I just tried GEdit and failed
I just tried GEdit on the basis of this thread to replace a very good but slow Komodo. GEdit is not good, or should I say, the plugins that let it be a python dev environment are not good. Perhaps I've selected and incompatible set of plugins, because they started off working somewhat decently, then syntax coloring was wrong for some files as though it was detecting the wrong language and the class browser turned blank, A lot of the plugins don't look like they've been touched in a few years so maybe they're unmaintained. Could someone post a list of of GEdit plugins that create a good django environment? Komodo Edit is very good except it's too slow.

How to group by two fields simultaneously.
I have the following:
Model Person
Model Stat
Model Stat Value
Model Team
A Team has a set of Stats relevant to it. A person is on multiple
teams, and has stats for his/her performance on that team which are
stored as Stat Values. Stat values are unique by Person, Stats, and
Team.
I want to build a view that will show team overviews from the point if
view of a single specific person. All his/teams, and the associated
stats.
So my view throws out a list of teams, filtered to the person and my
template looks like this:
{% for t in teams %}
{% for s in t.getStats %}
** I WANT TO NOW DO SOMETHING LIKE: **
{% for v in s.getStatValues(Person,s) %)
** EXCEPT THAT I CAN'T PASS ARGS IN A TEMPLATE. **
But if I don't pass in those arguments I'll get all the statValues for
everyone on the team, not just the person I'm looking at. I wouldn't
retrieve it all and then put an {% if v.person=p %} or similar in the
template would I?
This must be something fairly common. What am I doing wrong? It's an
easy SQL statement to write, but how to do it Django style?

Database schema migration - any tools available?
Hi all, I have a migrations tool made by me for an internal project. I couldn't find anything at the time and I made my own. It uses the Command pattern (took the idea from the Rails migrations) and plain MySql queries with a parser made with Antlr ... I know it is not portable but this may be changed. MySql is used because that's all I use and because I was thinking of cool features like parsing the queries and creating visual diffs between two migrations ... that's for when I'll have enough time. Is there such a tool for Django? If there aren't any maybe I could package it and release it as open source ... otherwise it would be nice to work with a polished project (mine is just a quick hack with some potential). --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Working with inline formsets to created/edit an object
I am very interested in this as well. I had to abandon formsets because they were too difficult to get working for creating associated objects at the same time as the original object. I was sure this was a common issue but could find absolutely no information about how to do this reasonably cleanly, even reverse engineering the source. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: MySQLdb + AMD64
Try using Linux then. I just created an Ubuntu dev platform for Django on my AMD64 and everything worked very easily. You can even install Ubuntu from windows using Wubi -- practically a one-click install. Python, MySQL, and all the libs are all ready to go for AMD64, you just install using the package manager that comes with Ubuntu. Not sure what you use for an editor but most are available for Linux also. I found that MySQL for Windows was very tough to get working under Vista. Plus, if you are going to go live then chances are your hoster will be using unix-like software over Windows. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

problem with the ImageField using ModelForm
Hi, i have a problem with the form.ImageField using ModelForm. I define a ImageField in my model and I configure all path in the settings file. I have no problem when i use the django admin interface : the images are uploaded correctly to the directory and correctly added in the DB. But when i use the form i make with ModelForm. Nothing append. I don't understand because i don't customise the form, i just exclude some fields. Is it possible there is a bug in ModelForm.ImageField ??

Re: Json Serialization / Form Validation error
I ran into this same problem but the code snippets you guys gave
weren't working. In case anyone is reading this in the future, here is
what you want:
dict([(k, [unicode(e) for e in v]) for k,v in errors.items()])
The above line will give a dictionary of field names mapping to lists
of errors.

how to use render_to_response, ajax and javascript variables
Hi,
Please can anyone help with an app architecture problem I am having?
(I am quite new to Django)
I have an app which which serves up XHR requests (via YUI3 io
uitility) to urlpatterns. The views make HttpResponses using
render_to_response like so:
return render_to_response("registration/register.html", {
'form': form,
}, context_instance=RequestContext(request))
That is all fine: The html content is rendered in the relevant div
(using a YUI3 io's success callback) .
But the problem I have - and I may be thinking about this in the wrong
way - is that I also want to pick out some variables from the response
to use in my js success callback. If I wasn't using django templating
this could be straightforwardly achieved with a JSON response parsed
client side. So my difficulty is that I want both a rendered template
response and some JSON response in the same callback... I have thought
about 'enriching' the render_to_response context with these additional
variables, inserting them in hidden html fields and then querying the
dom for their values - but that feels awkward and also means the
response has to be added to the dom before the js can act on their
values.
This seems like a familiar nut that must be well documented
somewhere... :) any help, pointers very appreciated.
Thanks
Alex

Re: how to use render_to_response, ajax and javascript variables
Thanks all. I may go with Matt's idea of serialising html + other data
to json and decoding client side. I'm not totally keen though because
this abandons a very nice rollup of functionality in django's
render_to_response (I am not familiar with how to write the template
as JSON and rendering to that. Keeping the template as html seems like
the right thing to do). I was hoping you'd scream 'don't be daft -
everyone does this...' :)

reverse relationships and their creation
Hi,
I am getting a 'QuerySet' object has no attribute 'reel_set' on a
reverse relationship query.
I am pretty sure the models are correct which has made me look at what
else might be the problem. So far I have thought of:
- no relationships instances have been created between the two models
so effectively the set is empty which is a problem - is it? (this
seems like an unlikely cause)
- the 'Reel' model was created *after* instances of its foreign key
had been created - so I am wondering if syncdb doesn't create the _set
field - this also seems an unlikely cause of the problem as adding
foreign keys to models with existing instances is likely to happen a
lot during development
- something to do with INSTALLED_APPS ? I have changed the order to
ensure that the foreign key model (Reel) appears before the model it
has a foreign key to.
- other ideas?
Thanks for any thoughts,
Alex

model instances, schema and template variables
Hi,
Just want to know if this is the correct understanding of how model
instances are passed to templates.
If I load a model instance object into a template - is it the case
that I also implicitly load in any instance objects it is related
through foreign key fields? It seems that these, and in turn, any
foreign keys those objects have, are also loaded.
eg
return render_to_response("startpage.html", {
'A': instance1,
}, context_instance=RequestContext(request))
so in the template I can do things like:
{{ A.fk_field.name }}
{{ A.fk_field.another_fk_field.name}}
Is this correct - and how should it be controlled - supposing I really
do only want 'instance1' without FK following.
Is it also the case if I want access to an instance's reverse
relationship objects I have to explicitly load those into the template
seperately?
eg
return render_to_response("startpage.html", {
'A': instance1,
'BList': instance1.other_set.all(),
}, context_instance=RequestContext(request))
so in the template I can do
{% for B in BList %}
do something with B
{% endfor %}
Sorry if this is answered elsewhere but just couldn't find it!
Thanks
Alex

Django has incorrect time
I'm having some strange behavior when using Django and Postgres. My system time zone is EDT and when running datetime.now( ) from a *Python* shell I get the correct time. If I run a Django shell through manage.py it is an hour behind. I similarly have set up a view on a web page to display the time and it is also an hour behind. Now this is where things get tricky. I have some database fields that default to datetime.now( ) and get updated to the same when changes occur to the objects the fields are contained in. The database gets the correct local time (say 10:30) but when these values are displayed by Django on a page they are again an hour behind. So, Django cannot present the correct value (one hour behind) to me, but somehow the correct time gets inserted in the database, and when directly displaying this value from the database in Django it is again one hour behind. It sounds like a time zone thing but I've tried setting Django to an eastern zone and also None (to use the system TZ) but neither seemed to make a difference.

django-registration0.8 args on /activation/complete/
Hi, Thanks for great package - just stuck now on how to update app specific user profile on /activate/complete/ Although I have seen the code (re ln 80 in django-registration/ registration/views.py) I don't understand how to write the correct url pattern and view params to pick up the activated user in my view so as I can add some app specific data for each user. In the url pattern I have: url(r'^accounts/activate/complete/$' ,'myapp.views.profile', name='registration_activation_complete'), and in the view I want this sort of thing so as I can complete the UserProfile(this fails because the request.user is empty): def profile(request): new_user = request.user profile = UserProfile(user= new_user) and in the model: class UserProfile(models.Model): user = models.OneToOneField(User) st = models.DateTimeField(auto_now_add=True) ... I think the problem is not understanding what my view receives from the 'activate' redirect: if success_url is None: to, args, kwargs = backend.post_activation_redirect(request, account) return redirect(to, *args, **kwargs) I have tried setting a username parameter in the url pattern and view with no success. How should this be done? I need a - oh that's how it works - moment. Any help very appreciated. Alex -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Connecting a django-registration signal to a function

Multiple authentication sources to one database
I am trying to write an application that allows two different kinds of authentication: Users in the wild can register and use the site with a new username, password and email and authenticate as usual, and others can use a single-sign-on solution provided by my university. django- cas (http://code.google.com/p/django-cas/) and django-cas-provider (http://nitron.org/projects/django-cas-provider/) both handle the single-sign-on solution, but they overload the username field to correspond to the username provided by CAS. This means that if someone registers as "johndoe" then someone who authenticates as "johndoe" with CAS will suddenly have access to the internals of the other account. Is there a way to separate out these authentication methods so that both can be used on the same django installation? (They both need access to the same database of information.) If this isn't possible, I may try to create a whole second instance of django running on the same database (but then they both will want to use the "auth_users" table anyways). -- You received this message because you are subscribed to the Google Groups "Django users" group.

terms of service (tos field) validation and error reporting from django registration package
Hi,
Does anyone know how to get the error message in the form template
when the user fails of check the terms of service form field when
using RegistrationFormTermsOfService ? The form returns due to
validation but I don't get the error message in
{{ form.tos.errors }} . Any ideas? Is it anything to do with the tos
field being a checkbox?
Thanks Alex

Slug auto-complete after save
Hi all,
Slug autocomplete feature is really cool with:
prepopulated_fields = {'slug':('title',)}
Is it possible to prepopulating slug field even after save - when I
want to change title for example?
Actually I use django-multilingual and prepopulating of slug works
only for the first language (en for example), when I switch to another
language tab (es for example) - the entity is already saved and I have
now prepopulating for Spanish language.
Is it possible to solve this issue somehow?
Thanks.

Re: Slug auto-complete after save
File "admin_modify.py" method "def prepopulated_fields_js(context)"
Line 11:
if context['add'] and 'adminform' in context:
should be changed to
if 'adminform' in context:
to allow slug be auto updated every time and not only on the entity
creation in admin.
Is there any setting to do it without changing Django internal source
code?

table namespace hygiene: should I try to rename auth_* tables, or should I use a separate database?
django 1.2, python 2.6, mysql 5.1, etc. I am sharing a database with others on my project, and I would like to keep the table namespace neat and tidy. After poking around the archives for a while, I can't see any good way to specify names other than the default auth_group, auth_group_permissions, etc. for the auth module. I don't want my tables to get confused with someone else's. "auth" is unfortunately a very generic prefix. One can imagine lots of people making tables named auth_something. Is this renaming something that can be done in a reasonable way? If not, I could create a new database, and devote it to the django stuff. Is that a good solution? Are there significant disadvantages to using a separate mysql database just for the django stuff? Is there maintenance overhead for the dba? (I don't know.) Are there any disadvantages, say, to doing trans-database joins, or having trans- database key constraints, vs. within a single database? Does anyone see any other optimal ways to keep my table namespace clean? Thanks Alex -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: table namespace hygiene: should I try to rename auth_* tables, or should I use a separate database?
I poked around a little, and it looks like MySQL actually does support foreign keys across databases. I guess my questions are: As long as the separate databases are not explicitly distributed eg. to different machines or different CPUs, is there any disadvantage to joining or constraining across database boundaries? And/or is there a good way for me to customize the names of the tables created by eg., auth, to dampen my urge to use a different database just for the sake of namespace hygiene?

Internationalization problems in Django 1.2 (beta 1 SVN-12678)
I've got some very simply templates in which marking strings as
translatable is not working. For example:
--- snip
{% extends "base.html" %}
{% load i18n %}
{% block content %}
{% trans "Password reset successful" %}
{% trans "You successfully resetted your password. A confirmation mail
has been sent. Check your inbox for further instructions." %}
{% endblock %}
--- snip
For example for this template, the first text is being translated. The
second one is just printed like {% trans "The text..." %}.
I'm using the trans-tag in a very simple way and exactly how I used it
numerous times without running into problems. Do you have an idea on
this? I tried everything that came to my mind - the problem persists.
Could it be a problem of the development version? I didn't find
anything on the tickets and bug reports...
Hoping that I did not miss something very obvious :-)
Thanks in advance

Re: Internationalization problems in Django 1.2 (beta 1 SVN-12678)
Posting this question made me rethink the problem... And it was a very
small mistake: {% trans "..." %} is not able to mark multilined...
Just use one line and everything will work.
Hope this helps someone :-)

User form input as variable for form action?
Hi there, Does anyone know if it's possible to take data input into a

{% if form.date.errors %}*** {{ form.name.errors|join:", " }}{%
endif %}
The date of the batch to save article
profile to (-MM-DD)
DOI: 10.1038/
{{ form.doi }}
{% if form.doi.errors %}*** {{ form.name.errors|join:", " }}{%
endif %}
Perhaps this is not the right way to go about this though? If anyone
has a solution it would be much appreciated.
Thanks

Printing out HTML that doesn't get converted to
I'm working on my first Django project and I can't seem to get
information printed out as I would like it. I'm trying to print out
quotes to a page with the newlines turned into HTML tags (similar
to PHP's nl2br function). So far I've been able to do this using the
__str__ function for the Quote model, but it escapes the tags into
html entities that I see the tags in my browser instead of the line
breaks. I'm using the development version of Django.
Here's what my __str__ function looks like:
return self.quote.replace('\n', '')
And I'm just printing them out with a generic view that looks like
this:
{% for quote in object_list %}
{{ quote }}
{% for a in quote.authors.all %}
—{{ a }}
{% endfor %}
{% endfor %}
I'd appreciate any suggestions. I'm rather new to Python, so I
appreciate all the help I can get :)

Filtering by group
I'm playing around with a TV quotes database and I'm trying to get all quotes from one TV series. My problem is that the quotes are directly tied to an episode of a TV series, not the series itself. How can I easily get a queryset that represents all quotes from that series? Here's a snippet from my models.py (removing irrelevant info): class Source(models.Model): name = models.CharField(max_length=50) slug = models.SlugField(max_length=20) class Quote(models.Model): quote = models.TextField(max_length=500) authors = models.ManyToManyField(Author) source = models.ForeignKey(Source) class TVSeries(models.Model): name = models.CharField(max_length=50) slug = models.SlugField(max_length=20, editable=False) class TVEpisode(Source): series = models.ForeignKey(TVSeries) episodenum = models.IntegerField() In my view, I'm thinking of something like the following, which obviously doesn't work: queryset = Quote.objects.filter(source=TVEpisode.objects.filter(TVSeries.objects.filter(authors__slug__iexact=slug))) Is there an easy way to filter by groups like this?

Link to different URLs by Class
I'd like to make a link to an item based on which class it is in. I'm
creating a quotes database that has quotes from movies, tv shows, etc.
Movie, TVShow, etc. are all separate classes, and they have separate
URLs for viewing them. I'm trying to create a link to the source based
on which subclass the source is in.
For example, the movie subclass should have a link like /movie/slug
and tv show should have a link like /tv/show/episodeslug and so on. I
can do this quite easily when I know which subclass something belongs
to (and therefore which URL to load), but I'm not sure how to do it
when the subclass varies.
To link to all quotes by a single author (the person that said the
quote), I use this code in my template:
{{ a }}
Is there similar code (like a series of if statements) that could help
me determine the context of the quote?

media server implementation - context processor, custom template tag, or custom filter
I already have {{ MEDIA_URL }} set in html, css, and js templates and
that's working great. I would like to start setting far future caching
headers on media files based on the git abbreviated commit hash for
each file. i can think of three options for implementing this and
would appreciate feedback, especially in regard to the processing or
performance penalties any of these approaches may incur. i've
implemented proof-of-concept versions of all of them in development
and they at least accomplish what I want, though I haven't yet done
any benchmarking.
as part of the production deployment process, a script is run which
essentially does the following: for every static media file, find the
git abbreviated commit hash which looks like "857vb4". the results are
written to disk as a python dictionary:
STATIC_ASSETS = {
"/media/image/button.png": "/857vb4",
"/media/image/submit.png": "/219cb3",
etc.
}
the dictionary has approx 100 entries and may grow to 200.
all of the approaches below generate html like this:
http://media.example.com/857vb4/media/image/button.png";>
http://media.example.com/219cb3/media/image/submit.png";>
but the actual paths on disk do not include version numbers. apache
has a re-write rule which removes the revision information, so that
clients can be told to cache the static files for a long time into the
future because whenever the file changes, the revision number in the
url will change. here are some ways i've come up with for adding the
revision info to the static file urls.
1) simple string filter
templates look like this:
and the template filter is approx:
@register.filter
@stringfilter
def get_file_version(value, arg):
if arg in STATIC_ASSETS:
value = STATIC_ASSETS[arg] + arg;
else:
value = arg;
return value
2) simple custom template tag
templates look like:
template tag code:
@register.simple_tag
def get_file_version(arg):
value = arg
if arg in ASSET_LIST:
value = ASSET_LIST[arg] + arg;
return value
The third option would be a custom context processor which adds
template variables to each page that are tied to the filename.
Are these approaches reasonable or do they incur too much processing
for, say, a page that has 10 or 20 static files (images, js, css)? Is
there a better way I'm overlooking? I'm trying to avoid approaches
which rename files on disk or do find-and-replace operations on
template files.
Any feedback appreciated.

Formsets or Forms with Subforms
I have been trying to find a fairly generic way of creating forms that fill related models similar to the admin method of presenting the main form and then multiple forms for related objects that can be added in batches (ex, the tabular form). This is a common requirement but I haven't been able to find any documentation. The web has some references to something called FormSets, which I think might do it but I don't know how to use them or if they even exist anymore, or if they will exist in a future version, or what. I found a couple of tutorials on how to build those types of forms using views/templates, but they are custom each time and I find I have to do the same thing over and over. Can anyone lead me to some documentation about how to do this? Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Python-requests seems to 404 with Django/Tasty-pie?
I just discovered that the requests library honors HTTP_PROXY, but does not
honor NO_PROXY.
Based on what you say below, I'm betting this is your problem, or at least
a part of it.
One solution is for you to explicitly unset HTTP_PROXY when you don't want
it.
Another is for you to specify a proxies dict for requests.
Good luck!
Best
Alex

I can't span relationships in list_filter
Django 1.3 supposedly supports spanning model relationships in
list_filter, but when I try to use this feature, the admin page
redirects me to an unfiltered page.
For example, I have an admin list page for a class that looks like:
class PlayerAdmin(admin.ModelAdmin):
model = Player
list_filter = ('team__year',)
When I go to the admin list page, I see the options to filter by year
along the right hand side, and they are correctly populated with the
distinct years I have in the database. But if I click on an option
(which says it will go to /?team__year=2010 in the status bar) I get
redirected to /?e=1. This clears any other filters I have set up as
well.
Does anyone know why this is happening? Do you need any more
information to diagnose the problem?

Model Inheritance and ModelForms
I've been scouring Google and the Django documentation and I can't figure out how to do this. I'm working on an inventory management system for my shop. My inventory models.py similar to the following: class ItemType( models.Model ): def __unicode__( self ): return "blah blah blah" itemType = models.CharField( max_length = 32 ) isBook = models.BooleanField() class InventoryItem( models.Model ): def __unicode__( self ): return "blah" itemType = models.ForeignKey( ItemType ) description = models.CharField( max_length = 256 ) class InventoryBook( InventoryItem ): def __unicode__( self ): return "blah blah" title = models.CharField( max_length = 64 ) In my web app, I create a ModelForm based on InventoryItem and present that to the user. Upon submission, the POST data is used to create an instance of InventoryItem. I then check to see if inventoryItem.itemType.isBook() is True - if True, I want to cast inventoryItem to an InventoryBook type so I can set the extra fields and call save() so that it creates records in both tables in the MySQL database. I started trying to add a method to InventoryItem that would return an InventoryBook instance after being given the title string, but that doesn't work because Python doesn't have prototyping/forward declarations. Am I approaching this completely wrong, or am I just overlooking something simple? Any advice or links to relevant documentation would be *much* appreciated.

Re: Model Inheritance and ModelForms
Tom, Thanks for the quick reply! However, when I tried that I got an error saying that inventoryitem "is an invalid keyword argument for this function". I fixed this by manually specifying the OneToOneField relationship with the parent class as inventoryItem and setting parent_link=True. With that in place, I get errors about InventoryItem fields not being allowed to be null within InventoryBook. This doesn't make sense to me since InventoryBook should only have a link to the parent and its own local book-specific fields - not the fields previously declared in the parent InventoryItem. I have not declared any models to be abstract (and in fact have not declared Meta: at all). If I need to manually specify all of the InventoryItem fields again in the constructor of the InventoryBook, I can. But doing so seems to defeat the purpose of using inheritance to begin with. Is there something I'm still overlooking?

prefetch_related - possible to avoid "IN" ?
Hi - I am using prefetch_related as an efficient way to populate a large list of objects whose attributes that are one-to_many relationship. We have cases where we return a list of around 10,000 objects. This produces an SQL query with an "IN" clause and a list 10,000 IDs. Is it possible to instruct pretch_related to not use the list of objects but to use the query that produced the list instead? Or to explicitly give pretech_related a query to use? If that is not possible is there another way to go about this? Thanks! --Alex -- You received this message because you are subscribed to the Google Groups "Django users" group.

Django mysql over ssl (2026, 'SSL connection error: Failed to set ciphers to use')
Hi, Summary: I'm getting this error "(2026, 'SSL connection error: Failed to set ciphers to use')", on the django error page and I don't know what i happening!!! I'm using apache / wsgi and my aplication it's on a virtualenv. The main problem is that I can't connect to a remote mysql over ssl. The first think checked was the ssl configuration... but it's all rigth becouse I can run all django commands, (runserver too) without any problem, and the aplications it's connecting to the remote database over ssl correctly. The next think checked was runserver response and the application doesn't raise any error... it works perfectly... With that two points i can see that the problem is in the wsgi, specifically with the libraries that load to run the application becouse it's the only think that I can see that is diferent from a runserver (executed inside the virtualenv) Anyone have had the same problem or can give me ant clue, I'm spending a lot of hours tryng to solve that. The next test will be change to nginx to see if the problem persist.. -- You received this message because you are subscribed to the Google Groups "Django users" group.

queryset._clone() in generic views
What is 'queryset = queryset._clone()' statement in django.views.generic.list_detail.object_list view used for? Has it something to do with prevention of usage of cached results, to allow QuerySet to reflect changes made to the database? Should I use _clone(), too, if I'm reimplementing this view in order to add some filtering? Or, maybe, I should use QuerySet.all() method instead (i.e., 'queryset = queryset.all())? -- You received this message because you are subscribed to the Google Groups "Django users" group.

fetching data from intermediate many-to-many table
Hello!
Assume we have the following models:
class Book(models.Model):
title = models.CharField()
sequences = models.ManyToManyField(Sequence,
through='BookSequence')
class Sequence(models.Model):
name = models.CharField(unique=True)
class BookSequence(models.Model):
class Meta:
unique_together = ('book', 'sequence')
book = models.ForeignKey(Book)
sequence = models.ForeignKey(Sequence, related_name='detail')
number_in_sequence = models.IntegerField()
...and are trying to select the sequences a concrete book belongs to,
along with the number of this book in the sequence:
def print_book_sequences():
book = Book.objects.get(pk=1)
for seq in book.sequences.select_related():
number_in_sequence = seq.detail.get(book=book,
sequence=seq).seq_number
print seq.name, number_in_sequence
So, the question is:
Is there any way in django to select sequence name and sequence number
in one sql query?
The code in print_book_sequences results in two sql queries per
sequence, one selecting name and one number.

Re: MultiValueDictKeyError in Django admin edit inline generic model
I am having a similar problem that started when I upgraded from django
1.4.x to 1.6.5
My parent model has a custom pk and the model in my inline is using the
default autogenerated id.
Here is some snippets from my models and admin:
(note I have edited down for simplicity and have not tested the code below)
class Transaction(models.Model):
form = models.ForeignKey(Form)
code = models.CharField(max_length=4)
class Form(models.Model):
form_id = models.CharField(max_length=255, primary_key=True)
form_type = models.CharField(max_length=5)
notes = models.TextField(blank=True)

class TransactionInline(admin.TabularInline):
model = Transaction
fields = ('code', )
extra = 0
class FormAdmin(admin.ModelAdmin):
list_display = ('form_type',)
readonly_fields = ('form_type', 'form_id')
fields = ('form_type', 'form_id', 'notes')

Listening to a django channel from outside a consumer
Hi,
The docs explain that it is possible to publish to the channel layer from
outside of a consumer:
https://channels.readthedocs.io/en/latest/topics/channel_layers.html#using-outside-of-consumers
I
need to do the opposite. I have a fairly complex python script that reads
live data from pubnub, processes it, and pushes it to consumers via groups
on the channel_layer. This works fine, but I need consumers to be able to
announce their presence to this script so that it can push them data (it
currently pushes to the channel layer only when it gets new data from
pubnub, which could be every 24 hours).
I've decided to solve this by having the consumers publish to a 'presence'
channel on connect. I now need the pubnub source script to listen to this
channel. I've tried adding the below to the script, and it no longer throws
errors, but it doesn't actually respond to messages. It successfully joins
the channel layer, but the message handler 'receive_json', never fires.
This is the class, and then the initiation further down in the code:
from channels.generic.websocket import JsonWebsocketConsumer
class channelConsumer(JsonWebsocketConsumer):
def __init__(self):
self.channel_name = 'source'
def join(self):
async_to_sync(channel_layer.group_add)('presence', self.channel_name
)
def receive_json(self, message):
print("Presence Detected")
# do some stuff
global channel_layer
channel_layer = get_channel_layer()
global listener
listener = channelConsumer()
listener.join()

Access the current instance from limit_choices_to?
Hi,
is there currently a way to have something like:

firstborn = models.ForeignKey('Child',
limit_choices_to={'mother':lambda me: me})
class Child(models.Model):
mother = models.ForeignKey('Mother', related_name='children')
(taken from http://code.djangoproject.com/ticket/2445 )
Basically I'd like to have access to the current instance of the
class, when working with limit_choices_to. Of course we can't use self
(we're still defining the class).
Thank you!

Adding properties to models at run-time.
Hi,
I've been trying for some time to create a polymorphic link with a
backwards-link from the associated model. The problem is the model is
django.contrib.auth.models.User... Is there any way to add this
functionality without changing the django core? Trying to call
setattr(django.contrib.auth.models.User, 'target',
generic.GenericRelation(MyUser) does not work. It instantiates an
attribute named 'target', but it doesn't work in the manner
intended...
from django.contrib.auth.models import User as Account
from django.contrib.contenttypes.models import ContentType
from django.contrib.contenttypes import generic
class User(models.Model):
account_polymorphic_link = models.ForeignKey(ContentType)
account_id = models.PositiveIntegerField()
account = generic.GenericForeignKey('account_polymorphic_link',
'account_id')
setattr(Account, 'target', generic.GenericRelation(User)) #this
doesn't seem to work
My problem is that I'm using auth.User (Account in the above example)
to store username/password and to leverage permissions and such, but I
can't look someone up by username and get at the information in my
derivative class...
Does anyone have any ideas/suggestions?
Thank you,
Alex.

Re: Adding properties to models at run-time.
Thanks for the reply, DR.
How would I use the generic relationship without the backward link?
I have the normal auth.user class, and I have the my.user class that
extends it and has a polymorphic link pointing at auth.user. The
problem occurs when I collect a login/password, because I can't lookup
my.user without the backward link, that is I can't
my.user.filter(account__username = x, account__password = y) because
polymorphic links don't allow this. I also can't move in reverse, the
auth.user.authenticate(username, password) function returns an
auth.user, and I am unclear as to how I would get a my.user from this
information without calling for my.user.objects.all() and comparing
the link (which seems terribly, terribly inefficient...). Is there a
way to start with the target (auth.user) and get to my.user backward
via the contenttype?
I know about AUTH_PROFILE_MODULE, but the problem is that the goal is
to have multiple user classes. Ideally there would be a way to
specify the user model as an attribute of the auth.user model (which
would be the heretofore missing backward link), but barring that this
isn't much use to me because the AUTH_PROFILE_MODULE would have
multiple values.
Any clues?
Thanks,
Alex.

With simplejson module (that is part of django distribution) you can covert

Re: Is it possible to output JSON like this?
It's strange. I've just try this example and it is good:
In [1]: results = []
In [2]: results.append( { 'date' : '2008-11-04 00:00:00', 'dayEvents' :
...: [ { 'title' : 'Event 1', 'location' : '1', 'id' : '1' }, {
'title' :
...: 'Event 2', 'location' : '1', 'id' : '2' } ] } )
In [3]: from django.utils.simplejson import dumps
In [4]: dumps(results)
Out[4]: '[{"date": "2008-11-04 00:00:00", "dayEvents": [{"id": "1",

Re: Confused about unittests and fixtures
GenericForeignKey and content type application itself look very doubtful for me. If you have a ForeignKey to the ContentType model then you depends on order with ContentType objects creates on syncdb. Because ContentType that references to some model can have different primary key any time you flush database. I've faced this issue than develop some application that has fixtures with ContentType references. Reference brakes when needed ContentType object has illegal primary key.

Re: global name 'Image' is not defined
I think you have a typo in this line, May be you write `Image.new` with
lowercase "L" not uppercase "I" as first char.

Re: Per-Test Caching?
