RSS error

[Gabriel - Iulian Dumbrava]

Hi guys,

I'm trying to make the rss work. I managed to call the
"LatestGalleriesFeed" function by using direct pointing in url
(commented out in the urlpatter bellow), but when trying to use the
generic view with the feeds mapping I get the error "object.__new__()
takes no parameters"

Thanks!
Gabriel - Iulian Dumbrava

This is my configuration:

from verticalsoftware.galleries.models import LatestGalleriesFeed

feeds = {
#'articles': ArticlesFeed,
'blogs': LatestEntries,
#'podcasts': PodcastFeed,
'gallery': LatestGalleriesFeed,
}

urlpatterns = patterns('',
(r'^feeds/(?P.*)/', 'django.contrib.syndication.views.feed',
{'feed_dict': feeds}),
#(r'^feeds/$', LatestGalleriesFeed()),
...


and the function is:

class LatestGalleriesFeed(Feed):
title = "Chicagocrime.org site news"
link = "/sitenews/"
description = "Updates on changes and additions to
chicagocrime.org."

def items(self):
return Gallery.objects.all().order_by('-date_added')[:5]

def item_title(self, item):
return item.title

def item_description(self, item):
return item.description

def item_link(self, item):
return item.get_self_url

Can you give an example of the second application where you put the templates,
settings and so on?
I'm trying to put all the media, templates in the application directory.
However, it's not clear to me how i can do this as you end up with 2 media 
url's.
One for the project and one for the applications, same goes for the templates.

thanks Erik,
By 'update' I meant a major addition/removal of text(say 100
characters).
Initially I thought of making hash of a page and comparing it to the
saved hash of the same page  at a different moment of time..But ,this
would
cause even a tiny change to be considered as an update..I would like
to use a filter to set an update of x number of characters.
May be using f=urllib.urlopen and
currentsize=len(f.read())  will let me find the number of added/
removed characters..and set the filter accordingly..

any other suggestions most welcome
harry

I agree with Thomas that at least some guidelines would be nice.
As what you and Steve have been saying about the need for a "Python for 
Djangonauts" class,
i think it would be a good idea also.
I'm wondering though what specific Python topics you would touch?
One that comes to mind is the use __init__,py and this modules in general as 
this
knowledge is needed to understand how you can split your models and views.

This would be what i would put in the guidelines for code structuring.
Topics i think would be interesting:
1. Project vs App
- What is a project? When do you use applications?
- Possible examples of coding structure
- 1 site in 1 project
- many sites in 1 project
- ...
2. Splitting models & views
3. How can you cleanly seperate an application further from a project
4. Building reusable applications
5. Advanced building methods
- Buildout
- Virtualenv
- ...

If we could agree on a list of topics, we can start writing it ourselves.
We have people here with lots of experience regarding these kind of
more advanced topics.
I wouldn't mind to write something on point 2 but that would need
to be verified by someone with loads more experience than me before
it could be published.

Benedict

I'd be tempted to answer : all of Python - hence my opinion that at
this point it's more about learning Python than anything else.

But the most obvious points are probably about Python's execution
model:
* what happens when a .py file is loaded into the interpreter, whether
thru direct execution ('> python somefile.py') or via an import,
* modules, packages, and the pythonpath
* import hooks and how django use them

This is already explained in Python's fine manual.

Ok, this is more Django-specific, and I agree that sharing experience
on these points might be a good thing.

> 2. Splitting models & views

It's a more general pattern: turning a module (single .py file) into a
package without breaking client code.

> 3. How can you cleanly seperate an application further from a project

Part of this topic is mostly generic dependencies management, but
there are indeed quite a few Django-specific points here.

> 4. Building reusable applications

There are already some threads, blog posts etc on this, but I've met a
couple issues never adressed so far.

Implementing accounts

[mf]

After finishing the core functionalities of my project it's time to
begin with other secundary but important things.

I've something like the following models.py file:

class Category(models.Model):
   name = models.CharField(max_length=30)

class Transaction(models.Model):
name = models.CharField(max_length=30)
description = models.TextField(blank=True)
amount = models.DecimalField(max_digits=12, decimal_places=2)
category = models.ForeignKey(Category,
related_name='transacciones', blank=True, null=True)

And this is what I want to do:

 Accounts: Each user can create different accounts.Example: the user A
have a home account with categories car and house, and a work account
with categories salary and bonuses. I don't know how to explain it
well, I'd like to have a "group of rows" for each account.

It seems pretty easy to do but I can't find the solution.

When I did something similar, I had the same SITE_ID for the two projects.
 The two sites still had their own settings.py and application source. 
The key things that were different in settings.py were that ROOT_URLCONF
pointed to different URLs, and TEMPLATE_DIRS pointed to different top
level templates.  In that way I have different sites, but still referring
to the same database tables, and crucially the same SITE_ID, so you
wouldn't have the problem with django-comments.

Would that work for you?

Tim.

.dates() bug or feature?

Hi all,

Anyone has explanation to this? :

>>> len(models.Rezerwacja.objects.all())
9
>>> len(models.Rezerwacja.objects.annotate(przyjazd=Min('transza__zajetosc__dzien')))
9
>>> models.Rezerwacja.objects.annotate(przyjazd=Min('transza__zajetosc__dzien')).dates('utworzona','year')
[datetime.datetime(2010, 1, 1, 0, 0), datetime.datetime(2010, 1, 1, 0,
0), datetime.datetime(2010, 1, 1, 0, 0), datetime.datetime(2010, 1, 1,
0, 0), datetime.datetime(2010, 1, 1, 0, 0)]

I expect to get ONE datetime.datetime(2010, 1, 1, 0, 0) rather then 5
which is |Min('transza__zajetosc__dzien')| ...

Validating or modifying admin inlines against main form

[graeme]

I need to do one of the following in the admin using Django 1.2:

1. Validate a value in a form against which objects have been added
using an inline form.
2. Add or delete related objects depending on the value in the main
model from.

The first would be preferable as the user would be able to decide
which was wrong and correct it appropriately.

I have tried doing this using the model's clean() method, its save()
method and a post_save signal. In all cases I cannot get the new
related objects.

I have thought of using form validation, but I cannot figure out how
to get the values from the inlines in the validation of the
ModelAdmin.form.

Re: DjangoCon 2011

[Steve Holden]

There seemed to be a general feeling that a change of venue should head
Eastwards rather than South. So we are looking primarily for East coast
locations as an alternative to Portland for 2011.

The choice of venue was made in advance for this year - effectively we
took over an existing contract. This is the first time anyone has
suggested a non-hotel venue.

I haven't really heard much support for a university venue from the
community at large. They have both advantages and disadvantages. Of
course PyCon used a university location for the first three years. After
we outgrew the original location the conference's size made it difficult
to find university locations large enough (according to the people who
made the choices - I only chaired for three years).

It would be best not to cast the net too wide, given that a year ahead
is a relatively short planning time frame for a conference of this size.

You might also have a look at Providence, RI. There's an airport, it's
an hour from Boston by car, and they have an active tech community
there:

http://rinexus.com/
http://providencegeeks.org/
http://www.pbn.com/Schillings-38-Studios-signs-lease-at-One-Empire-Plaza,52603

Good restaurants abound and entertainment options are at least extant
if not quite as rich as Portland, OR. Venues are likely to be far
cheaper than Boston.

get_or_create failuire

[Szymon]

Hi,

Problem: sometimes (not always) get_or_create is trying to create
duplicated record.

Model:

class online(models.Model):
 postac = models.OneToOneField('postac.postacie',
related_name="lista_online")
 data = models.DateTimeField()

Code snippet:

o =
online.objects.filter(postac__user=request.user).exclude(postac=request.session['postac'])
o.delete()
o, c = online.objects.get_or_create(postac=request.session['postac'],
defaults={ 'data' : datetime.now()+timedelta(minutes=15) })
if not c:
o.data = datetime.now()+timedelta(minutes=15)
o.save()

Database schema:

  Column   |   Type   |
Modifiers
---+--
+-
 id| integer  | not null default
nextval('spoleczniak_online_id_seq'::regclass)
 postac_id | integer  | not null
 data  | timestamp with time zone | not null
Indexes:
"spoleczniak_online_pkey" PRIMARY KEY, btree (id)
"spoleczniak_online_postac_id_key" UNIQUE, btree (postac_id)
Foreign-key constraints:
"spoleczniak_online_postac_id_fkey" FOREIGN KEY (postac_id)
REFERENCES postac_postacie(id) DEFERRABLE INITIALLY DEFERRED


PostgreSQL error:

Database of course is PostgreSQL, Django 1.2.3 (btw. nice version

Re: DjangoCon 2011

[Steve Holden]

Without wishing to seem non-responsive, can I just point out that we
can't keep extending the search indefinitely. First of all, we need to
make a decision reasonably quickly.Secondly, these venue searches take
time. While it costs nothing to "toss something out there", there *are*
costs involved with investigating available venues.

Consequently I am unlikely to look at any particular place unless it is
clearly supported by a number of people. And having had Chicago, New
York and Washington DC in our sights I am not inclined to extend that
list without a strong indication of support from a broad cross-section
of the community.

I hope nobody takes this the wrong way.

 Steve

Admin returning the wrong string

[Caomhin]

I have a slightly strange occurrence happening which makes no real
sense to me so I thought I'd see if anyone had any helpful hints...

My app stores people's first and last names, however for privacy
reason unless a user is logged in when browsing the website they will
only see "Firstname Initial" instead of "Firstname Lastname".  This is
achieved by a models.py containing:

def __str__(self):
return self.full_name()

def full_name(self):
return smart_str('%s %s' % (self.first_name(), 
self.last_name()))

def anonymize_name(self):
if self.last_name():
return smart_str('%s %s' % (self.first_name(), 
self.last_name()
[0]))
else:
return smart_str('%s' % (self.first_name()))

What is confusing me however is the Admin site for this model, or more
accurately the Admin page for another model which uses Person in a
many-to-many inline.  The dropdown menu seems to show "Firstname
Lastname" about 75% of the time and "Firstname Initial" the other 25%,
obviously returning anonymize_name instead of full_name somewhat
randomly (this has been tested with a selection of records and across
multiple browsers with what can best be described as sporadic
variation.

The anonymize_name is only referenced in views.py for the specific
views that it's required, and admin.py doesn't import views.py so it's
making the choice purely from models.py it would see.  ANy insight or
suggests would be much appreciated.

Steve,

This seems totally reasonable.

Looking at this from a different perspective, given that there are a
large and increasing number of python-based startups in NYC, would it
make a difference re: which city was chosen if we (in NYC) were able
to solicit sponsorships from VCs and tech firms here (in NYC)?

It might, though the sponsors would need to commit in advance.

The main issue would be the cost of accommodation, which can be very
high in the city. Do you think you could get sponsors to offset those
costs? I'm finding it difficult to imagine how that could practically be
done.

JSON and Blackberry

Hello django experts,

I'm creating a web service that returns a json application as content
type but every time that I try to consume this with a blackberry

I try with another json service and it's working fine in the
blackberry. Here is my example service, what i'm doing wrong? It's
something about the headers in the HttpResponse?

I have no clue why the httpconnection can retrieve any data of my
django service.

I hope someone can helpme.

Really slow performance on webfaction

[Peter Harley]

Hi all,

I'm trying to figure out possible causes for really slow performance
of my site on my production server on webfaction - it can take up to
15s to load!

It only seems to be a problem on the home page of my site and it also
doesn't seem to be anything like too many queries. Using the debug
toolbar, I got the following information:

User CPU time   1060.838 msec
System CPU time 97.985 msec
Total CPU time  1158.823 msec
Elapsed time13099.062 msec

It also tells me that the cache has been hit, meaning only a few DB
hits. On my test server it loads very quickly on a cache hit.

Obviously from this information no one is going to solve the problem,
but if you can help me by suggesting where to look or how to get some
more useful profiling information on a production server that would be
great.

Cheers,

Pete

Re: Really slow performance on webfaction

[Shawn Milochik]

Do you see anything at all like this if you run your app from your development 
box? 

You can always use the Python debugger to trace for your code and look for 
bottlenecks.
(Awesome tutorial) http://www.doughellmann.com/PyMOTW/pdb/index.html

Also, put in logging and add log.debug statements in various stages of the 
code. From the timestamps you can home in on the trouble spot.

Re: Where do you put your business logic in django? Organizing big projects in django.

[Thomas Weholt]

Inspired by the discussions in this thread I've created a reusable app
that mainly consists of a couple of management commands, like
startbigapp ( working name ) which is a crude hack of the startapp
code in django. It creates module for models and views instead of the
standard views.py and models.py. Another command is addmodel
   which will support the module layout
created by startbigapp, but will also create scaffolding using generic
views and basic templates for new/update/list/delete of the specified
models ( the models doesn`t have fields, that will have to be added
manually ). It saves some time and reducing repetetive typing. I was
thinking of making a command that would take an existing app and
generate a new version of the app splitting models ( and perhaps views
? ) into modules. The app will be a collection of helper methods for
code organizing and generation of boilerplate code. Any thoughts or
ideas?

I`ll upload it to the cheeseshop as soon as I can get time to
debug/test a bit more. The code isn`t pretty at the moment, but it
seems to get the job done.

Have you guys seen adoptahacker.com? I'm sure that Jon Wegener and the team at

In terms of getting hotel rooms sponsored, we might be able to VCs to offer 
sponsorship for this (though we should at least reach out to  Charlie O'Donnell 
@ First Round Capital to get his take on this).

Bug in model inheritance?

[phill]

This looks quite a bit like a bug, but we may be off the reservation
in terms of how we're using the product. (Disclaimer: I'm relatively
new to Django, and extremely new to the codebase that I ran into this
on).

We've got a form of schema-inheritance going on in this project in
order to accomplish shared-id-space and the ability to relate models
to one of a number of different types. The way that we've broken it
out runs us into a strange inconsistency in Django that specifically
affects our ability to serialize the objects. Here's a simplified
version of what we're doing:

class Entity(models.Model):
entityType = models.CharField(editable=False,max_length=50)

def __init__(self, *args, **kwargs):
super(Entity, self).__init__(*args, **kwargs)
self.entityType = self.__class__.__name__

def __unicode__(self):
return 'Entity: %s %s' %(self.entityType, self.id)

class BasePerson(Entity):

entity = models.OneToOneField(Entity, parent_link=True)
name = models.CharField(max_length=50)

class Meta:
abstract = True

class Kid(BasePerson):
school = models.CharField(max_length=50)

class Adult(BasePerson):
job = models.CharField(max_length=50)



When I dump instances of these models out using the standard fixtures
serialization, instances of Kid will serialize the 'entity' field, but
instances of Adult won't. The reason is because Adult's entity field
is marked primaryKey=True. Kid's is not. There appears to be a caching
issue here, because if I swap the order that Kid and Adult are defined
in.. the error reverses (now Kid's field will be marked pk).

Is this a bug? If not, what's the reasoning behind this behavior? Is
there a better pattern for accomplishing this kind of inheritance?

Thanks in advance for your help.

Have you looked at the bug tracker? It might be a post-1.0 feature, or it's 
just that nobody mentioned it. You should check, their tracker is completely 
open and they're very responsive and reactive (I've reported a fair number of 
bugs on the EAPs and betas, and overall I enjoyed the interaction)

Re: Bug in model inheritance?

[Alec Shaner]

As to whether it's a bug or not I have no idea, though it seems so.

If you use:

entity = models.OneToOneField(Entity, parent_link=True, primary_key=True)

it will create the primary key in both Kid and Adult tables, which
sounds like what you want?

Just for the record: "views.py" and "models.py" are actually modules.
What your command creates are packages (folders with an __init__.py
module).

Re: Really slow performance on webfaction

[Bill Freeman]

Are you running with the same data set both places?

The biggest speed problem I ever had in deployment was because real data
blew the database up with a huge join.  My dummy data on the test box didn't
evoke it.  (Fix was to get a simple query set and loop over it so that another
query could be qualified without a m2m join).

User.get_profile() not working

[adj7388]

Django newbie issue. Just trying to understand. I'm setting up a
simple UserProfile class to link to User (as described in several
places in documentation). Here's what I have --- a simple example of
storing the user's website in a profile

#In myapp/models.py
class UserProfile(models.Model):
def __init__(self, website='http://www.default.com'):
super(UserProfile, self).__init__()
self.website = website
user = models.ForeignKey(User, unique=True,
related_name="user_profile") <-- note related_name...see below
website = models.URLField()

#In myproject/settings.py
AUTH_PROFILE_MODULE = "myapp.UserProfile"

Now I create a empty db
run: python2.6 manage.py syncdb
All tables look good in postgres.

Now in the python shell:

Python 2.6.5 (r265:79063, May 12 2010, 10:28:19)
>>> from django.contrib.auth.models import User
>>> from myapp.models import UserProfile
>>> u = User(username='testuser', password='s')
>>> u.save()
>>> up = UserProfile(website='www.overridethesite.com')
>>> up.user=u
>>> up.save()

So far so good
Over in Postgres, everything looks fine:
mydb=> select au.id as id, au.username, up.id as upid, up.user_id as
fk_userid, up.website from auth_user au join myapp_userprofile up on
(au.id=up.user_id);
   id | username | upid | fk_userid | website
--+--+--+---+-
2 | testuser |1 | 2 | www.overridethesite.com
(1 row)

Now back in the python shell, trying to use the profile from the user
obj:

>>> u.user_profile.values()  <--- works fine using the related_name I set in 
>>> the UserProfile class
[{'website': u'www.overridethesite.com', 'user_id': 2, 'id': 1}]

### But get_profile() fails:

>>> myprofile = u.get_profile()
Traceback (most recent call last):
  File "", line 1, in 
  File "/home/myusername/webapps/django_boosters/lib/python2.6/django/
contrib/auth/models.py", line 370, in get_profile
self._profile_cache =
model._default_manager.using(self._state.db).get(user__id__exact=self.id)
  File "/home/myusername/webapps/django_boosters/lib/python2.6/django/
db/models/query.py", line 336, in get

self._result_cache = list(self.iterator())
  File "/home/myusername/webapps/django_boosters/lib/python2.6/django/
db/models/query.py", line 282, in iterator
obj = self.model(*row[index_start:aggregate_start])
TypeError: __init__() takes at most 2 arguments (4 given)

Can anyone tell me what's going on, or what I'm doing wrong? Thanks in
advance.

Content length (which you could also get using the HTTP header "Content 
Length") won't necessarily tell you if content has changed. I think your 
problem is a candidate for http://en.wikipedia.org/wiki/Levenshtein_distance 
(calculating the "distance" between two strings), for which I think there are 
Python implementations.

Depending on your requirements, you could add other heuristics to detect major 
changes, e.g. load the page into an XML parser and only check certain 's. 
But further suggestions would require more information on your problem.

Kind regards,

Erik

Description: S/MIME cryptographic signature

Formsets, forms and related editing

[Axel Bock]

Hello again,

after some trying and not coming to a successful end I might need a hint or
two with the following construction.

Assume a pilots flight log: Each flight can have several legs, and a
purpose. So basically the model looks like this:

Mission:
Pilot
Purpose
...

Leg:
Mission: ForeignKey('mission')
Departure
Target
Time

The relationship is Mission (1) --> (*) Leg (one to many). The legs are
REQUIRED for the Mission to be complete.

Now I am trying to design a view which presents an input for the Mission AND
the leg part, so when submitting you create a Mission including its legs.
There are also several restrictions, one of them being that a pilot can only
log his own Missions. For this reason I do not present a "Pilot" entry
field, and intend to fill in the Pilot later (it's of course a registered
user, so I am following the procedure described in the Django docs -
save(commit=False), update the field value).

But this does not work. :/

The view is roughly this code:
mission = MissionForm()  # a modelform
LegFormSet = inlineformset_factory(Mission, Leg, form=LegForm, extra=1,
can_delete=False)
legforms = LegFormSet(prefix="legformset")
render_to_response("...", { ... }, context_instance=...)

The View seems to work all right, but the processing does not. The
processing code is roughly:
mission = MissionForm(request.POST).save(commit=False)
# it seems to abort here with the error "The Mission could not be
created because the data didn't validate"
legs =[f.save(commit=False) for f in LegFormSet(request.POST,
prefix="legformset")]

Are there any best practices when doing such kind of thing? Am I doing it
wrong?


thanks in advance for any help & greetings,
Axel.

Fixing Missing Template Error

[octopusgrabbus]

I am getting a Missing Template exception

Exception Type: TemplateDoesNotExist
Exception Value:

registration/login.html

My urls.py looks like this:

from django.conf.urls.defaults import *
from django.contrib.auth.views import login
.
.
.
urlpatterns = patterns('',
(r'^$', main_page),
(r'^login/$', 'django.contrib.auth.views.login'),
 )

I would like to correct the exception, but do not know where to begin.
This does not work either under runserver or the default configuration
under Apache.

Small examples work with the general project. This is a login
application under a project.

Thanks for any pointers.

What's your TEMPLATE_DIRS value in settings.py?

Inside your template dir you need to create the file registration/login.html

The auth contrib app doesn't provides default templates.

Re: IDE for Python/django

For me, at least in ubuntu 64 bit, pycharm is indeed terribly slow.
And this on a icore7 machine with 8 gigs of ram. Otherwise I like it,

Re: Really slow performance on webfaction

[pjrhar...@gmail.com]

Thanks for the help guys. I started trying to log things, and only
then did I notice that I'd missed the obvious - one of the few queries
was taking 11s!

Turns out it was a pointless join from a weird use of queries (a
queryset contructed one place with more filters added elsewhere in an
odd order). Also turns out that, as expected, it was a case of having
a much smaller set of test data on my dev server, so it wasn't all
that slow on there.

Fixed (I hope - its now loading in at most 2s, disappointingly it
still doesn't seem to make much odds whether it hits the cache or
not...) by just making the query a bit more sane. I suspect there's a
few more places where I can improve on similar things that just aren't
causing such a headache because the data set isn't so big for a
different model.

Thanks,

Pete

iPhone talking to Django server (matching session)

[Danny Bos]

Heya,

I've got a Django application talking to an iPhone sending photos and
User data back and forth. I figured the best way to approach this
(tell me otherwise) was to log the user in on the server and pass the
iPhone back the 'session ID' in a JSON array.

Then when the iPhone sends me back some info, they send me that same
'session ID' and I match that to the associated user content in order
to get the User details. Does this make sense? Is it the way to go in
order to pass User details back and forth to an iPhone.

If so.

How do I find the User when the iPhone passes me back the 'session
ID'?

Thanks in advance,
Hope all is well your side of town ...

Model field choices

[Derek]

I have a model which has choices specified for the "offer_type" field:

class Coupon(models.Model):
offer_types = (
(1, 'Percentage Off'),
(2, 'Amount Off'),
(3, 'Free'),
)

business = models.ForeignKey(Business)
offer_type = models.IntegerField(choices=offer_types)

How do I then retrieve the "human readable" values when referencing a
Coupon object?  Right now Coupon.objects.get(id=1).offer_type returns
the numeric value only ("3" instead of "free"... which I suppose is to
be expected).

Thanks!

You should find that your model instances have a
get_offer_type_display() method that you can call to retrieve the value
that the user sees in the interface. These methods are added for each
field with choices set in its definition.

Re: Removing the 'site' (not the website/url) field from django-comments

Good idea, but that won't work unfortunately as we use the 'Site'

Re: form validation for empty checkboxes that are not required (and they are the only fields present)

Adding a hidden garbage field works.  Seems like it's just a little

LOGIN FORM

[Saad Sharif]

Hi all,
   I want to create  a simple login form in django..Please
help I am a complete beginner

My Code:
{% csrf_token %}
username 
password 
 login 


Error Message (when I press login button) :

Forbidden (403)

CSRF verification failed. Request aborted.
Help

Reason given for failure: CSRF token missing or incorrect.


In general, this can occur when there is a genuine Cross Site Request
Forgery, or when Django's CSRF mechanism has not been used correctly.
For POST forms, you need to ensure:

* The view function uses RequestContext for the template, instead
of Context.
* In the template, there is a {% csrf_token %} template tag inside
each POST form that targets an internal URL.
* If you are not using CsrfViewMiddleware, then you must use
csrf_protect on any views that use the csrf_token template tag, as
well as those that accept the POST data.

You're seeing the help section of this page because you have DEBUG =
True in your Django settings file. Change that to False, and only the
initial error message will be displayed.

You can customize this page using the CSRF_FAILURE_VIEW setting."


Please help me out

Why did you do that? and not:

 #In myapp/models.py
 class UserProfile(models.Model):
user = models.ForeignKey(User, unique=True,

related_name="user_profile") <-- note related_name...see below
 website = models.URLField(default='http://www.default.com')

That's cause __init__() of a model actually takes more arguments than
you allow. Redefining __init__ goes something like:

> class UserProfile(models.Model):
>def __init__(self, *args, **kwargs):
  website = kwargs.get('website', "default_url")
>super(UserProfile, self).__init__(*args, **kwargs)
>self.website = website

Note, I said _something like_ there could be more ways to do it.

Re: User.get_profile() not working

[adj7388]

Good grief. After spending hours trying to figure out what was wrong,
I immediately found the problem after making this post. Here's the
solution:

I had overridden UserProfile.__init__() like this:

class UserProfile(models.Model):
def __init__(self, website='http://www.default.com'):

while its superclass looks like this:
class Model(object):
...
def __init__(self, *args, **kwargs):

Somewhere deep inside Django the 'model.__init__()' was being called
to create a UserProfile passing it a bunch of parameters it was not
prepared to accept. So I just changed it to:

class UserProfile(models.Model):
def __init__(self, website='http://www.default.com', *args,
**kwargs):

... and all was well. That explained the 'TypeError: __init__() takes
at most 2 arguments (4 given) ' message.

This seems to be because you have overwritten the __init__ method of
the model. Don't do that. There's no need to, as simply instantiating
a model with keyword parameters does what you want:

UserProfile(website='www.google.com')

How to get an ajax call to return both QuerySet and paging info in Django

[Dmitrij]

I am trying to implement paging across ajax calls. The page should not
refresh when the user wants to see the next x num of results.

Here is my problem. Returning the QuerySet is super simple. I just do
(sumaJson is custom)

data = serializers.serialize('sumaJson', result_page.object_list,
relations=('first_major', 'country_of_origin', 'second_major'))
return HttpResponse(data, mimetype="application/json")

Now I also want to return things like

result_page.has_previous()
result_page.has_next()
result_page.paginator.count

and so on. I for the life of me can't figure out how to get both
across in one response. I can't add this info to
result_page.object_list because then the serializer fails. If I
something of the sort of

simplejson.dumps(paging_info + result_page.object_list)

Then in the javascript the QuerySet is no longer a list of objects but
just a big string of characters which can't be interpreted with

$.each(data.data, function(index, item){

I tried some bad hacks like creating a fake object and putting it in
the object_list, serializing this and then deleting the object. This
allows me to get the data across. However, I don't want to be creating
and deleting fake objects.

I don't want to meddle with the serializer. I don't want to send a
second ajax request once I get the querySet back to get the paging
info.

Am I missing something? Is there an easy way to get both across in one
response? Thanks!

Re: User.get_profile() not working

Using *args and **kwargs might work

then maybe

self.website = kwargs.get('website', 'default.com')

I don't know about a fake object, but surely if you put everything you
want in a Python dict and then serialize that it will arrive in
JavaScript as an object with named fields, which you can use as you want
by referencing the fields as object attributes. Or am I missing something?

Re: How to get an ajax call to return both QuerySet and paging info in Django

[Dmitrij Petters]

Well that would require me to use simplejson.dumps(data) right? I need to
use my custom serializer in order to do a deep serialization of the model to
model dependencies. As far as I understand, serializers are meant to take
querysets or something of the sort, not dictionaries containing various
kinds of data. Please correct me if I'm wrong. So I can't do something like
serializers.serialize('json" {'queryset' : queryset, 'paging_data' :
paging_data}). Similarly if I use simplejson.dumps, I lose the ability to
get that deep serialization.

Re: Bug in model inheritance?

[phill]

Alec,

Thanks.. yeah, your fix forces the fields to pk=True, which doesn't
redundantly serialize the field with it's custom name in my case. If
for some reason you wanted to ensure that the field was serialized
using it's custom field name though.. there doesn't appear to be a way
to do that. I'm pretty convinced this is a bug.

[Saad Sharif]

Hi all,

I created a simple login form

What is the correct way to copy an object from one model to a similar model?

[Yo-Yo Ma]

I have two models that are identical in structure except one has 2
extra fields. The second one is used for record keeping and is never
edited by users. The system takes the first model and copies it to the
second model, adding some extra meta information, all when a certain
action is performed against the first model.

What is the best practice for this?

spam.attribute_one = foo.attribute_one
spam.attribute_two = foo.attribute_two

Or, is there a pattern that works well?

Re: Import Error

[Yo-Yo Ma]

(r'^login/', include('macrohms.views.login')),  is incorrect.

the include() function, pertaining to urls.py is for including other
URL confs (so you can have sub-sections of your site contain their own
urls.py). You'll want to replace that line with:

url(r'^login/$', 'macrohms.views.login')),

Note, I changed two additional things - I changed your tuple to a
url() function call instead, and I added a $ at the end of the URL
pattern (denotes the end of a string in regex). The url() function is
the "cool" way to define URLs.

Re: Import Error

[Saad Sharif]

Thanks a lo :)

but there is a new error

The Error:

Forbidden (403)

CSRF verification failed. Request aborted.
 Help

Reason given for failure:

CSRF token missing or incorrect.


In general, this can occur when there is a genuine Cross Site Request
Forgery, or when Django's CSRF
mechanismhas
not been used correctly. For POST forms, you need to ensure:

   - The view function uses
RequestContextfor
the template, instead of
   Context.
   - In the template, there is a {% csrf_token %} template tag inside each
   POST form that targets an internal URL.
   - If you are not using CsrfViewMiddleware, then you must use
csrf_protecton any views that use the
   csrf_token template tag, as well as those that accept the POST data.

You're seeing the help section of this page because you have DEBUG = True in
your Django settings file. Change that to False, and only the initial error
message will be displayed.

You can customize this page using the CSRF_FAILURE_VIEW setting.

Re: IDE for Python/django

[Eric Elinow]

While I wouldn't say Pycharm is 'terribly slow' (on my dual-quad xeon Mac Pro 
w/8 gigs of ram running OSX 10.6.4), I will say that it is noticeably slower 
than my current Python IDE of choice, Netbeans 6.9.1 which is relatively snappy 
though YMMV.

Re: Import Error

[Yo-Yo Ma]

User logs into your site (SaadsDjangoSite.com). User goes to
CriminalCSRFSite.com while logged into yours. They put a script tag in
their page that has a post-back to 
ttp://saadsdjangosite.com/delete-everything-and-kill-kittens/.
This causes the user's logged in browser to make a request to your
site, and delete everything and kill kittens, all without the user
knowing what happened.

Follow those instructions. Make sure you put {% csrf_token %} right
after your open  tag.

The error page that comes up comes with a list of three possible
sources of error.

Have you ruled out those?
