Have you had a look at the sites framework yet:

Re: Web Designer

[Markus Gattol]

I'd say most people us a simple text editor such as Vim, Emacs... If you use 
runserver and and your browsers auto-reload for that tab then that's all you 
need. If you want to be a bit speedier then you can use things like 
Sass/Compass for your CSS and maybe HamlPy for your HTML. Both have "watch" 
commands that watch your .sass/.haml files and automatically create the 
.css/.html which would then be picked up be runserver which in turn gets 
reloaded by your browser's tab for which you set the autoload toggle.

for HTML
 - https://github.com/jessemiller/HamlPy

for CSS
 - https://github.com/chriseppstein/compass (is written in Sass)

The odd thing being email_config_set is a related name for a
ManyToMany field. I'm not sure why django is trying to resolve it into
a field.

To make it even more odd, this error occurs when DEBUG = TRUE and not
when DEBUG = FALSE when testing with runserver.

I've been trying to solve this for days now with much googling/pdb/

Re: FieldError on ManyToMany after upgrading to Django 1.3

[Russell Keith-Magee]

Hi Philip,

I can't say I've seen the error you report.

My immediate question when I see reports like this is "what else are
you doing?". Django has an extensive test suite, and things like m2m
fields are tested very heavily. Outside of Django's test suite, there
are thousands of applications out there using Django, and many of them
are using Django 1.3, and this is the first time that this particular
problem has been reported. So, you are clearly doing *something* that
is unusual (whether you know it's unusual or not).

What we need is a reproducible test case -- the smallest possible
sample of code that works under 1.2.7, but breaks under 1.3.1. That
will provide us the basis on which to debug the problem, and form the
core of a regression test to make sure the problem doesn't occur again
in the future.

Yours,
Russ Magee %-)

Yes, I've seen similar problems in two sites I'm running. I suspect it
has to do with dynamically created models and startup timing effects
in our case. I'm not sure when it started and it's really hard to test
because it only happens in production (mod_wsgi / DEBUG=False) and I

I am indeed using psycopyg2 and pg8.1, which version did you move to in 
order to solve the problem? I have just been using 8.1 since it was the 
default for CentOS 5, but I also see the 8.4 is available via yum.

Re: FieldError on ManyToMany after upgrading to Django 1.3

[Philip Mountifield]

I also have a great deal of dynamically generated models. Interestingly 
in my case I find the issue when using the development server with DEBUG 
= TRUE, I've not yet tried it in deployment.


I'll take a look at your github, thanks for sharing the link.

Out of interest, with respect to David's comment about postgres 
versions, do you use version 8.1 or another?

Re: FieldError on ManyToMany after upgrading to Django 1.3

[David Markey]

I actually haven't moved.. I'm still using django 1.2.x. :)

Although we plan to move to PG 9.1 and django 1.3 within the next few
weeks(we are already using both in testing)

I think i read something somewhere in the django 1.3 documentation that PG
8.1 was not supported any more(could have dreamt it though).

you will have to do this in python - but then django is nothing but

Reuse admin for views when some fields are from remote sources

[cesar.ortiz]

Hi,

We have some fields that will appear in the view that we won't to be
part of the model. They are from other system and we don't wish to
store them in order to avoid the problems that will arise with the
duplication of data.
We also would like to reuse the admin as much as possible in order to
avoid to create our own templates.

Those remote fields will be read/written to the remote system.
Which would be the best way to implement this behaviour in django?

Thanks,

-- César

Re: Reuse admin for views when some fields are from remote sources

[Ilian Iliev]

If these fields are not field in the model class you won't see them in the
add/edit of the admin.
If you want to show them in the view(list) section of the admin you can
define them as properties,
example:

class MyModel(models.Model):
# field here

@property
def remote_property(self):
return remote_property

class MyModelAdmin(admin.ModelAdmin)
list_display = ( 'remote_property', 'other_model_field')

HY010 Function sequence error (mssql django-pyodbc)

[PyMan]

Hi guys, I'm experiencing a problem with ODBC driver. I'm quite sure
is not a django problem, but I'm posting here 'cause maybe someone can
help me.

I'm using Python 2.6, Django 1.2.0, pyodbc 2.1.7, django-pyodbc (not
the last version, but it's ok for this django version).

In the settings the DATABASES['default']['OPTIONS']['driver'] is
setted up to 'SQL Native Client' or 'SQL Server Native Client 10.0'
and the MARS_Connection is True.

I get the error "HY010 Function sequence error" when doing some query,
I don't get the error if using 'SQL Server' as driver (but it's slow
since it can't use MARS well, I mean chunked reads).

I experience the problem with mssql 2005 and 2008 too.

I could understand I get the problem when reading/writing "many"
records (not so many tough). For example I have a table with about
1700 records and the Mytable.objects.all().delete() works for the
first 100 records and then the above error is raised (note that django
has an internal setting CHUNK_SIZE setted up to 100!).

Another example is then Mytable is empty and I do this:
for item in Mytable2.objects.all():
Mytable.objects.create(...)

600 records are created and then the error is raised (Mytable2 has
about 1700 records...)

Upgrading to the last django-pyodbc version and to the pyodbc 2.1.11
can't solve things.

Thank you for your time!

Multiple Image Field in a model

[NavaTux]

Hi all,

   I have a filed(ImageField) in my model.Also I want to have
multiple ImageFields.How to have more than one ImageFields only in
django model.Is there any need to derive that ImageField as a seperate
new model which holds as a foreign key of another one?

This is my model:

class Report(models.Model):
name = models.CharField(max_length=1024)
data = models.TextField()
image = models.ImageField(upload_to=settings.IMAGE_UPLOAD_PATH,
blank=True, null=True)

I need to display atleast 4 imagefields for this model object?

Re: Multiple Image Field in a model

[Philip Mountifield]

I would put the images in a seperate model such as "ReportImage" and 
make a foreign key to "Report", and finally I'd use the "inlines" admin 
feature for ReportImages to display them on the same page as the report.

postgres- can nulls be first when sorting in asc order?

[j_syk]

Hello-
On Friday afternoon I migrated a project from sqlite to postgres.
Everything went smoothly and I was able to go home for the weekend and
be happy. Yay.
This morning I was informed that the sort order is different. I have a
DateField for a due date that is set as not required, however leaving
it blank treats it as ASAP. I'm assuming this is a result of the
different sort orders between sqlite and postgres. I got used to
sqlite sorting it like: "None, Oct, Dec, etc." but now I am getting
"Oct, Dec, etc., None".

Here are the options I'd rather not do:
-Go back to sqlite
-set the default as some date years ago and override the display value
in templates (I already use this method to make a None show as "ASAP")
i.e. {% if item.due_date == '1999-1-1' %}ASAP{% else %}
{{ item.due_date }}{% endif %}
-add another field to the model, a boolean field for  ASAP, set it to
true if the due date is blank and sort by that first (this may
actually be a decent option)

I'm hoping there is a setting in postgres that can be changed for the
sort priority of null.
Is this any easy way to solve this problem before I start reworking
all the code?

The main difference is that mine is a DateField. So I can't just make
it 0 instead of None.

Accessing sum in templates

[David]

Hello

In my view I have:

a = Person.objects.select_related().get(pk=pk)
b =
a.issue_set.filter(resolution_date__isnull=True).aggregate(Sum('type__severity'))
variables = RequestContext(request, {
'person': a,
'issue': b,
})
return render_to_response('contacts/view_person.html',
variables)

b produces the query:

SELECT SUM("issues_type"."severity") AS "type__severity__sum" FROM
"issues_issue" LEFT OUTER JOIN "issues_type" ON
("issues_issue"."type_id" = "issues_type"."id") WHERE
("issues_issue"."person_id" = 1 AND "issues_issue"."resolution_date"
IS NULL)

How can I access and use type__severity__sum in my template please ?
This is what I have tried:


{% for is in person.issue_set.all %}
Issues
{{ is.type__severity__sum }}
{% endfor %}


Thanks for any help

You can control the order of how nulls sort with pgsql (at least, 8.3
and above) by appending 'NULLS FIRST' or 'NULLS LAST' to the 'ORDER
BY' clause of a select query. I'm not aware of a way to
administratively choose 'NULLS FIRST' for all queries, and you may
find it tricky getting 'ORDER BY ... NULLS FIRST' into a django
produced query.

Wrong view prefix on Django 1.3, mod_wsgi and mutliple URLconfs

[lucamag]

Hi all,
I'm using multiple URLconfs for my simple django application.
Everything works fine in development mode, but I'm getting a strange
error when moving to Apache 2 with mod_wsgi.

My main urls.py looks like:

---
from django.conf.urls.defaults import *
from django.conf import settings

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
# Include app URL structure
(r'^alerts/', include('mymodule.urls')),
# Uncomment the admin/doc line below to enable admin
documentation:
(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
(r'^admin/', include(admin.site.urls)),
)
---

and the urls.py for my first module is below.
Please note I'm using a prefix view:

---
from django.conf.urls.defaults import *
urlpatterns = patterns('assistant.views',
# Example:
(r'^view/(?P\d+)/$', 'detail'),
(r'^$', 'index'),
)
---

How can it be that the once running in Apache my main application
works fine, but the admin page fails with a "TemplateSyntaxError"
because it tries to use a wrong view name,  It looks for
"assistant.views.django.view.generic.simple" rather then
"django.views.generic.simple"?

The problem disappear if merging everything in one urls.py file
without any view prefix.

Thanks in advance!
Luca

[maxwell]

(All code is some kind of pseudocode, just for better reading I have
an Invoice model:

 class Invoice(models.Model):
// many fields here
I need to attach some products (with price for unit, and quantity
fields) to this invoice, so I made additional table:

class InvoiceProduct(models.Model):
product = models.ForeignKey
quantity = models.IntegerField
unit_price = models.DecimalField
invoice = models.ForeignKey(Invoice)
So, this is almost first question — «Could it be done better way?»

My second problem is, that in django admin I have manage these models
by inlines: Screenshot But my customer wants otherwise. He wants one
button (Add product) then pop-up windows appears, with fields:
product, quantity, unit price. He fills them, press OK. Then pop-up
window closes and line with "product fields" appears in main form. I
suppose I need override admin form template? Or I need to write my own
widget or smth like that?

Sorry for my English.

Cloudfiles Storage Backend

[Kurtis]

Hey,

I really want to build a storage back-end for cloudfiles. The snag is
that cloudfiles containers do not allow for a hierarchical directory
structure. Everything must be in a "base directory".

Does anyone have any suggestions on methods for performing this
conversion of a hierarchical directory structure to a flat directory
structure?

Thanks!

Russ,

Thanks very much for helping to separate the processing.  I'm trying to 
implement a setup using your suggestions.  I've hit a snag on a detail:

> class SearchForm(forms.Form):
>organization = forms.ModelField(Organization)
>search_term = forms.CharField(max_length=100)

What's a ModelField?  I was unable to find it in a search on 
docs.djangoproject.com.  I found it referred to in an abstract way on a google 
search, but not as an actual attribute name.

Thanks!

David

Good to know. I am using 8.4, I may look into adding the order by into
a .extra() call.
Thanks

Due to the urgency, I went with option 3 on my list (adding an ASAP
field to the model), It just frustrates me that I now have a column
that is false except when the due_date column is null. Just seems like
such a waste, I wish I could have hooked into the due_date. Good news
is that this guarantees the right sort for any db, should I ever need
to switch it.

FileField parser populating other fields

[Paulo VJ]

Hello Everyone,

I'm looking to building an Model where it's fields are populated by the 
contents of a PDF file.
I've come to this solution, one I didn't like:

class ContaPdf(models.Model):
  conta_pdf = models.FileField(upload_to='conta_pdf')
  
class Conta(models.Model)
  data_inicio = models.DateField()
  data_fim = models.DateField()
  data_vencimento = models.DateField()
  telefone = models.ForeignKey(Telefone)

@receiver(pos_save, sender=ContaPdf)
def pdf_parser(sender, **kwards):
  # Parses data from PDF file and create/save Conta object.

Is there any easier way to do this, considering I'll be using mostly 
django.admin as interface?
I can't quite see the alternatives.

Thanks a lot,
Paulo

Re: Web Designer

[Sushirod]

For Mac I use coda and for Windows I realy like Notepad++.

As far as WYSIWYG editors go I`ve never seen one that`s better than
Dreamweaver, wich I`d say it`s not that wysiwyg at all. To be honest
there's no such thing as a WYSIWYG, I think its just a marketing term
that propose a software with a very junky visualization of what your
are doing.

The real deal it's to experience the code rendered in browser (try to
use all of then for production purpose). That`s how your user will
experience it.

I`d also say that vi (or vim) are realy good to work "in server" via
the SSH, I use it sometimes before going to production.

Make good use of plugins such as firebug (firefox) and the google
chrome code inspector.

good django twitter login tutorial

[Guido]

Hey all,

I want to build a website where users log in with their twitter
account like you see a lot on the internet.

I read some things about OAuth 2.0 etc. but don't understand any of
those docs.

I am a total beginner (I just got the poll application to work) and
have never build a site with users/logins.

Do you guys know a tutorial that explains all the basics (possibly
explains what tables are made etc and why) for django and twitter
login?

Thanks!

p.s. of course I have googled, however I can't find any good stuff.
More general good django tut sites would be welcome too!

Russ and Tom,

Thanks to both of you.  It's  working.  Here's what I did (Sdo is the 
Organization):

# snip of models.py
class Sdo(models.Model):
name = models.CharField(max_length=255, unique=True)
background = models.TextField(blank=True, null=True)
address = models.CharField(max_length=255, blank=True, null=True)
phone = models.CharField(max_length=255, blank=True, null=True)
url = models.CharField(max_length=255, blank=True, null=True)

def __unicode__(self):
return self.name

class Document(models.Model):
number = models.CharField(max_length=255)
title = models.CharField(max_length=255)
edition = models.CharField(max_length=255)
scope = models.CharField(max_length=255, blank=True, null=True)
sdo = models.ForeignKey(Sdo)

class Meta:
unique_together = (('number', 'title', 'edition'),)

def __unicode__(self):
return u'%s %s %s' % (self.number, self.title, self.edition)

# snip from forms.py
class SearchForm(forms.Form):
sdo = forms.ModelChoiceField(queryset=Sdo.objects.all())
document_search_term = forms.CharField(max_length=100)

# snip from views.py
def search_form(request):
form = SearchForm(data=request.GET)
if form.is_valid():
sdo = form.cleaned_data['sdo']
document_search_term = form.cleaned_data['document_search_term']
documents = Document.objects.filter(sdo=sdo, 
number__icontains=document_search_term)
results = RequestContext(request, {
'form': form,
'documents': documents,
'show_results': True
})
return render_to_response('search_form.html', results)
else:
return render_to_response('search_form.html', locals())

# contents of search_form.html
{% extends "base.html" %}
{% block external %}
{% endblock %}
{% block title %}SDO Search{% endblock %}
{% block head %}SDO Search{% endblock %}
{% block content %}

  

  
SDO
{{ form.sdo }}
Document Number
{{ form.document_search_term }}
  


  
  
{% if show_results %}
{% include "document_list.html" %}
{% endif %}
  
  {% endblock %}


#contents of document_list.html
{% if documents %}


  {% for document in documents %}
  
{{ document.number }}{{ document.title }}{{ 
document.edition }}
  
  {% endfor %}


{% endif %}

There is a simple url.py entry for /search_form/.  It provides a list of the 
documents that have the sdo_id that matches the id field in Sdo for the 
selected value of the Sdo name in the sdo field of the request.

I know some of this is goofy as I'm working from tuts and the examples in the 
docs and such, but I would like to say that I'm impressed how relatively easy 
it is to get something working in Django.  Especially with such a helpful users 
mailing list!

circular dependency in models.py

[Amit Sethi]

I think the solution to this might actually be very simple . I have an
app stories that looks something like this at the moment . It is in
the same file ideally i would like if both of them were related by
foreignkey but that is not possible because they are in same file and
there are declaration issues(NameError).

class Story(models.Model):
"""Story model."""

author = models.ForeignKey(User, blank=True, null=True)
title = models.TextField(_('title'), )


class Vote(models.Model):
"""
A vote on an story by a User.
"""
user = models.ForeignKey(User)
story = models.ForeignKey(Story)
votes = models.SmallIntegerField(default=0)

if i make a foreignkey in story , I have to write a very complicated
query to ensure no user can vote twice.  In case I keep it in vote its
incredibly complicated to write a query to get the score for a story
and order stories by vote what should i do .


Thanks
Amit

Re: Cloudfiles Storage Backend

[Kurtis Mullins]

Thanks Alex.

Yeah, I actually did try to use that. Currently I'm using it for SFTP (and
having some issues with the URLs provided by the SFTP plugin). The problem
with the Cloudfiles implementation is that, according to what I've read and
tried, the API it used is outdated. Rackspace has changed quite a bit since
it was built. So for now, it's not a readily available resource for
Rackspace Cloudfiles. If anyone can prove me wrong, I'd be very happy :)

Question about losing port number.

[Chen Xu]

I have a general question about  PHP:
So basically I have a link, and I want the href to be absolute., so I
do 'https://' . $_SERVER['HTTP_HOST'] . '/login' ; this gives me
https://127.0.0.1/login on my local; however, what i really want is
https://127.0.0.1:9090/login, it is missing ":9090".

Could anyone please help?

Using exists() on queryset for a User

[Kurtis]

I'm trying to check if a user with a specified email already exists.
According to the docs, it's better to use the .exists() method.

I tried this:

if User.objects.exists(email = data['email']):
raise forms.ValidationError(u'Email Already Exists')

However, I get this error:

exists() got an unexpected keyword argument 'email'

I'm just going to assume I went about this the wrong way. Any
suggestions on how to do it the right way?

looking for an event planning app

[j_syk]

I'm looking to build a site to plan events for a small convention.
I've been looking around for an
Here's what I'm looking for:

-Users can sign up to host an event at a given location
-User can pick event length in hour or 30min increments
-There can't be more than one event at the same location and time
-Chart/spreadsheet view of the whole event, or a specific location

It would be like a meeting space planning application. I'm kinda on a
time crunch so finding an existing app would be nice, if not, this
won't be too hard to implement myself (and may have to post a repo if
it's any good).

Anyone know of any suitable apps to check out? Thanks

can't get STATICFILES to work (Django dev version)

[nara]

I am having trouble getting STATICFILES to work. I have read the docs,
and followed the instructions, but I never get my css files to load.
My current workaround is to put all the css inline in my template
file, but that should not be a permanent solution.

I am running the django dev version, and I am using the built-in
server. Here are my changes:

1. I placed my media (css) files under /home/nara/media
2. I added '/home/nara/media' under STATICFILES_DIRS
(django.contrib.staticfiles is already in INSTALLED_APPS)
3. I added {{STATIC_URL}} (no spaces) in front of the reference to
static files in my template file.
4. I restarted the server.

No further changes. I don't have additional copies of the static files
anywhere else, such
us under my project, or app.

Looking at the result in firebug within firefox, I get an HTTP
response of 200 on my css files
(happen to be css/blueprint/screen.css and print.css), but the files
are null. Clearing
the cache, restarting Firefox etc. do not help.

I have been fighting this issue for several days now, and have tried
many things,
but the above description is for my current state.

Thanks
Nara

Are you sure that covers the OP question? I think django-oauth is
useful to create oauth providers; for consumers (like the one he's
trying to build) he needs a client. For that, I found python-oauth2 at
https://github.com/simplegeo/python-oauth2; the readme there has even
an example of authenticating a django app with twitter.

Re: DJango doesn't work with Oracle 11g on Windows 8

[Benjamin Welton]

Very true, oracle is quite difficult to get working (properly at least) 
in general on windows. Much less what amounts to a beta version of 
windows. I haven't heard back from the original poster on this, like i 
said im very curious to see if he was able to get everything working 
correctly. Everything should work for him since there doesnt seem to be 
any major kernel changes in windows 8 (unless he's using the Protogon 
file system, then all bets are off).

PicklingError: Can't pickle :

I have upgraded psycopg2 to version 2.4.2 (the FixedOffsetTimezone
should contain a fix for pickling errors - 
http://initd.org/psycopg/docs/tz.html),
but I still see the error. I have contacted newrelic about the issue,
but they see this issue not related to newrelic.

Has someone a hint how I can nail that issue down?

Many thanks, tom

Postgres on OSX Lion

[adrian]

Postgres comes pre-installed in OSX Lion for the first time (and mysql
is no longer present).  Yeah!
I installed psycopg2 using pip.

Then I kept getting the error message:

psycopg2.OperationalError: could not connect to server: Permission
denied
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?

The simple solution is to change your settings file so that HOST =
'localhost'.   If it is set to '127.0.0.1'  or not specified you will
get the error above.

Re: Platform system with Django?

[Ian]

So I already have my site up and running in PHP/mySQL, but I want to
move to Django (and learn it in the process!)

The way I do it now is have a main table of posts, and the table of
posts has a column called "site".  If the user accesses myproject.com/
mySite, it loads the posts from the database for everything with the
condition site=="mySite"
So I do it the same way in Django?  Use the same logic, with Django's
sites framework?

That makes my life easy since the application logic is already done!
How do I handle the subdomain, though?

Thanks!

Re: can't get STATICFILES to work (Django dev version)

[nara]

Xavier,

I followed the blog, and at the end, my css files were not getting
pulled in.
I then tried doing a ./manage.py collectstatic, and this does collect
all
static files. Unfortunately, running the server still does not serve
my
css files.

I have spent too many cycles on this issue now. I will go back to my
workaround of just placing css inline in the templates, and later,
use Apache on my local machine to serve the css files.

Thanks
Nara

Forms from models API example.

[Jack720]

I'd just like to state that I did try and find this out on my own
first but "django form model api" isn't a vary narrowing search. I've
read through the documentation multiple times but I'm still a little
stuck. It would appear most of the documentation/examples are
outdated. I'm certain this has been answered before I just can't find
the answer.

First, is the current forms api solid? Or are major changes still
planed? It seems like it went through a major change in 2007 and now
2010? The newforms versus forms gets a bit hairy.

2ndly, As a bit of constructive criticism the main tutorial should
really have included a section on the forms api. At the very least the
end of the tutorial should let you know it exists. I know how time
keeps documentation from getting done. I get the whole learning to
multiply before using a calculator thing but I didn't even know about
that part of the API for a while and it's fairly major. When it comes
to forms the tutorial leaves us at multiplication and didn't even tell
us there was a calculator.

3rd, and the main question. Does anyone have a simple working example!
I'm trying to use the form api using my models but the code in the
documentation seems to have a bit of a chicken egg problem. They seem
to show a view that displays a new form or posts and saves a form but
doesn't show how we got the form for a specific record id in the first
place! I'm just trying to create a simple list of records with CRUD.
simple enough just like the admin interface only I'll be putting a
bunch of other code around this.

password_reset_form_save() got an unexpected keyword argument 'request'

[Ben O'Day]

I recently upgraded to Django 1.3 (from 1.2) and noticed that our
password reset functionality isn't working.  I do have the templates
customized, but am using the default view/form files for this.
Looking at the django.contrib.auth.views file, I can't see the issue
either (the parameters in the opt dict seem to match the expected
params on the form, etc)

here is my urls.py config...

# password reset
(r'^password_reset/$', 'django.contrib.auth.views.password_reset',
{'template_name':'registration/dasn_password_reset.html',
'email_template_name':'email/dasn_password_reset_email.html'}),
(r'^password_reset/done/$',
'django.contrib.auth.views.password_reset_done',
{'template_name':'registration/dasn_password_reset_done.html'}),
(r'^reset/(?P[0-9A-Za-z]+)-(?P.+)/$',
'django.contrib.auth.views.password_reset_confirm', {'template_name':
'registration/dasn_password_reset_confirm.html'}),
(r'^reset/done/$',
'django.contrib.auth.views.password_reset_complete', {'template_name':

here is the error...any ideas?

Creating an imageField from a charField

[Mehrms]

Does anyone know how to instantiate an imageField using just the URL
of the image?

I am storing my URLs to images in a charField, but I am letting the
user interact with the imageField. Everything works fine to render the
imageField and I can use the imageField to upload an image. The url of
the stored image is safely stored in the database in a charField. The
only problem is I can't figure out how to pass the image url to the
imageField when I dynamicly create the imageField.

Is there a way to bind the data from the charField to the imageField.
I looked through all the data binding documentation and it doesnt show
how to bind data on a per field basis.

Any suggestions would help. The reason I have the url in a charField
is because its a property in a sudo triplestore.

Here is a sample of the code for my form.

class MetadataForm(ModelForm):
"""
Based upon the metatype create the correct field for this form.
"""
def __init__(self, *args, **kwargs):
super(MetadataForm, self).__init__(*args,**kwargs)

type_id = self.instance.metaType_id

if type_id != None:
self.fields['value'] = self.createField(type_id)

def createField(self,type):

metatype = MetaType.objects.get(id=type)

if (metatype.type == 'charField'):
return forms.CharField(widget = forms.Textarea,
required=False)
if (metatype.type == 'imageField'):
f = forms.ImageField(required=False)
   return f

Thanks for the help,

Brian

I'm not sure what you're referring to with the 2010 change. The forms
API has been very much stable since 2007, and is covered by Django's
backwards compatibility policy.

Thanks for the feedback -- we're certainly aware that more tutorials
are needed, we just haven't found the time (or the willing volunteers)
to write them. Forms would certainly be a good candidate for a new
tutorial.

Well, the pieces are all there [1] [2]; it's just not obvious how to
put them all together. Here's an example of an update view:

from django import forms
from django.http import Http404, HttpResponseRedirect
from django.shortcuts import render
from myapp.models import MyModel

class MyForm(forms.ModelForm):
class Meta:
model = MyModel

def my_view(request, object_id):
try:
obj = MyModel.objects.get(pk=object_id)
except MyModel.DoesNotExist:
raise Http404

if request.method == 'POST':
form = MyForm(instance=obj, data=request.POST)
if form.is_valid():
form.save()
return HttpResponseRedirect('/some/url/')
else:
form = MyForm(instance=obj)

return render(request, 'example/template.html' {
'form': form
})

The only differences between this example and the simple form example are:
  * You start the view by retrieve an object matching the view
arguments, raising 404 if the object can't be found
  * You pass that instance to the form when you construct the form instance.

I know this isn't the same as a full length tutorial, but I hope it's
enough to get you going.

Re: can't get STATICFILES to work (Django dev version)

[nara]

Good news, my static files finally work. (I wanted to make
one last try before giving up). Bottom line, I did not
have to make any changes to my original settings.py or urls.py.
All I did: created a static dir. under my app's directory, placed
the css files under it, and put '/static/css/blueprint/screen.css' to
refer to the external css. That was it.

Here is the head section of my template file, list.html:

  
  
  


Thanks

Re: can't get STATICFILES to work (Django dev version)

When you want to access say screen.css, how do you put it in your template??

Re: can't get STATICFILES to work (Django dev version)

Hi,

Using a static directory like that on the development server sounds wrong and 
you'll most probably have issues when the site goes live.

>From what you said, it looks like you are confusing STATICFILES_DIRS and 
>STATICFILES_ROOT.

Regards,
Xavier.

 I have read and followed the docs on static files.
 django.contrib.staticfiles is in INSTALLED_APPS
 (by default), and I have set STATICFILES_DIRS to where my static files
 are (/home/nara/media). (I have
 tried with and without a slash at the end of this absolute file path).
