Description (last modified by )
Administration list view shows choices in filters not responding to the limit_choices_to field for the field.
For example, if we have
class Color(models.Model): value=models.CharField(...) warm=models.BooleanField(...) class Thing(models.Model): title=models.CharField(...) color=models.ForeignKey(Color, limit_choices_to={'warm': True}) class Admin: list_filter = ('color',)
We will get all the choices of Color objects listed in the Filter/By Color section instead of getting only those, which are warm.
To fix this, the line
self.lookup_choices = f.rel.to._default_manager.all()
at class RelatedFilterSpec(FilterSpec) in the file django/contrib/admin/filterspecs.py has to be changed to
if f.rel.limit_choices_to: self.lookup_choices = f.rel.to._default_manager.filter(**f.rel.limit_choices_to) else: self.lookup_choices = f.rel.to._default_manager.all()

This seems like the logical thing to do. If someone disagrees, feel free to set back to decision needed. Can someone provide a real patch please.

I tested out the patch and it works. Not sure it this should have a unit test or not it seems really simple and none of the other filters are currently being tested.

I found one case, where it fails: that is when Q() objects instead of dictionaries are used to limit the choices. Here is the simple fix:
if f.rel.limit_choices_to: if type(f.rel.limit_choices_to).__name__ == "dict": self.lookup_choices = f.rel.to._default_manager.filter(**f.rel.limit_choices_to) else: self.lookup_choices = f.rel.to._default_manager.filter(f.rel.limit_choices_to) else: self.lookup_choices = f.rel.to._default_manager.all()

The patch by Archatas doesn't work with the following limit_choices_to:
limit_choices_to = {'parentisnull': False}

Take limit_choices_to
into account for list_filter

The same thing is done in the get_choices()
method in /django/db/models/fields/__init__.py
, ideally we would reuse this, but because I don't want to rewrite a function I don't completely understand, I have just copied the approach taken in get_choices().
The patch I just attached should work exactly the same way as get_choices()
.

Version: | SVN → newforms-admin |
The admin code in trunk won't be updated. Moving this to newforms-admin. It does look to still be a problem in that branch. Please submit patches against newforms-admin.

(Please don't change ticket titles to make them less readable by chewing up space with an unnecessary prefix. We already have the version field and patch checkboxes and the like to differentiate between things.)

Problem originally reported against old admin, should not block merge of newforms-admin.

doesn't matter as the problem still exists and is major as it may render admin pages unusable.

As suggested by comment:7 new patch uses field's get_choices to construct a list of (id, title) pairs. Though a bit bigger (3 lines instead of 1) this looks cleaner to me.
