First, here is an example model:
Foo
name
Bar
foo = fk(Foo)
FooBar
bar = fk(Bar)
Given the above (simplified) model, the following works fine:
>>> FooBar.objects.filter(bar__foo__name='blah')
However, if I want to use that for a 'list_filter' in the Admin to
filter FooBars by 'name' I get the following Error:
myproject.foobar: "admin.list_filter" refers to 'bar__foo', which
isn't a field.
For kicks I tried using 'bar.foo' with the same results. I tried
adding '__name' or '.name' to the end (ie.: 'bar__foo_name'), but that
didn't help either.
Can't 'list_filter' filter across mutiple ForeignKeys?
And now I attempt to answer my own question:
It occurs to me that it may be related to the inability to sort such
items in the 'list_display'. For example, in FooBar I also have the
following property defined:
def _get_bar_foo(self):
return self.bar.foo
name = property(_get_bar_foo)
And in the 'list_display' for FooBar:
list_display = ('name')
Which works great, except that column is not sortable, which is fine
in this case. Even so, I would still like to view only FooBars in
which bar.foo.name = "blah" via 'list_filter'.
