New description:
On django 1.10.6 and python 2.7.9 given this Model and ModelAdmin:
{{{
class Bar(models.Model):
name = models.CharField(
max_length=256
)
class Foo(models.Model):
name = models.CharField(
max_length=256
)
bar = models.ForeignKey(Bar)
class FooAdmin(admin.ModelAdmin):
search_fields = ['bar__pk']
}}}
Each search returns:
{{{
File "/venv/local/lib/python2.7/site-
packages/django/contrib/admin/views/main.py" in __init__
78. self.queryset = self.get_queryset(request)
File "/venv/local/lib/python2.7/site-
packages/django/contrib/admin/views/main.py" in get_queryset
346. qs, search_use_distinct =
self.model_admin.get_search_results(request, qs, self.query)
File "/venv/local/lib/python2.7/site-
packages/django/contrib/admin/options.py" in get_search_results
908. if lookup_needs_distinct(self.opts,
search_spec):
File "/venv/local/lib/python2.7/site-
packages/django/contrib/admin/utils.py" in lookup_needs_distinct
32. field = opts.get_field(field_name)
File "/venv/local/lib/python2.7/site-packages/django/db/models/options.py"
in get_field
619. raise FieldDoesNotExist('%s has no field named %r' %
(self.object_name, field_name))
Exception Type: FieldDoesNotExist at /admin/app/foo/
Exception Value: Bar has no field named u'pk'
}}}
Same code works fine in 1.8.16.
UPDATE: i've updated the test case as searching for the pk of the admin
model does not work in 1.8.16 too
