Comment:
I fixed this by changing:
django/contrib/admin/util.py
{{{
#!python
def get_limit_choices_to_from_path(model, path):
""" Return Q object for limiting choices if applicable.
If final model in path is linked via a ForeignKey or ManyToManyField
which
has a `limit_choices_to` attribute, return it as a Q object.
"""
fields = get_fields_from_path(model, path)
fields = remove_trailing_data_field(fields)
+ if len(fields)==0:
+ return models.Q()
limit_choices_to = (
hasattr(fields[-1], 'rel') and
getattr(fields[-1].rel, 'limit_choices_to', None))
if not limit_choices_to:
return models.Q() # empty Q
elif isinstance(limit_choices_to, models.Q):
return limit_choices_to # already a Q
else:
return models.Q(**limit_choices_to) # convert dict to Q
}}}
