I have a friendship model for users and want to retrieve all the posts
my friends made.
class Friendship(models.Model):
from_friend = models.ForeignKey( User, related_name='friend_set' )
to_friend = models.ForeignKey( User, related_name='to_friend_set' )
class Post(models.Model):
text = mode
I'm validating a form, and use forms.IntegerField(min_value=0,).
If I submit a -1 value in that field, it throws a TypeError: not all
arguments converted during string formatting.
How come it doesn't raise a forms.ValidationError, and how should I
catch a negative value in this field?

Ok! Thanks for clearing that up for me, I'll filter it manually.

I have a model that looks something like this:
class Collection(models.Model):
user = models.ForeignKey(User)
item = models.ForeignKey(Items)
date = models.DateTimeField()
I'm trying to retrieve a list of unique users ordered by the last time
they added something to their collection.
I would

Thank you!

Yes! It does!
What an amazing timesaver that small line was :-)
Is it possible to actually access the rating directly from the
template?

Good point, I have consider
I have book editions in my database. Users can rate editions. If they
want, they can also add them to their book collection.
Here is a simplified overview of the models:
class Edition(models.Model):
title = models.models.CharField(max_length=255)
binding= models.models.CharField(max_l
I tried to use the @login_required decorator on a view that takes post
data.
Why isn't there an option to have the request object passed to the
login form?
Then it would be possible to have the loginform pass the post data to
the view that depends on it.
Does anyone have any clever workarounds f

I want to fetch a list of items in my database, and I have their id
ready:
my_ids_to_get = [ 1, 3, 2, ]
In mysql I would fetch them like this:
SELECT * FROM table WHERE id IN (1, 3, 2) ORDER BY FIELD( id, 1, 3,
2 )
This would preserve their order.
Can I build this query with the native django

I want to add a recursive relationship to the built-in User model - to
store relationships between users. Are there any (non-hairy) ways to
do this?

It doesn't look as the form object is subject to this automatic html
escaping, because you can pass html into the form object like this:

I try to do a raise forms.ValidationError('oh no'), but the
HTML tags are escaped when I render my form as {{ form }}.
Tried to do raise forms.ValidationError(mark_safe('oh no')),
but the HTML-tags are still escaped.
Any way to get around this?
