Re: Inconsistent keyword filtering on FK

I'm getting a 'cannot resolve keyword' on a objects.filter that
doesn't seem to make sense.

Here is the model:

class Person(models.Model):
   payee = models.ForeignKey(
       Payee,
       null=True,
       blank=True,
   )
   ut = models.ForeignKey(
       Utility,
       null=True,
       blank=True,
   )

The problem:

Utility.objects.filter(person=1144) # works fine
Payee.objects.filter(person=26) # gives us FieldError: Cannot resolve
keyword 'person' into field

Is this what you need??

Payee.objects.filter(

    person = Person(id=26)

)

or.. Payee.objects.filter(

    person__id = 26

) - but this would be slightly more performance hitting i think.

 

I've tried to follow this around, finding myself in the Options object
where I printed out self._related_objects_cache.items() ... Utility
has about 20 other models that define a FK to it, and appear in the
related objects cache. Payee has about 13 models that define a FK to
it - but only one of them appears in the related object cache (and
it's not 'person')

I haven't been able to track it beyond this point to anything
conclusive. Any suggestions on where to look next?
