Related names are broken when using AllLookupsFilter

models.py

from __future__ import unicode_literals

from django.db import models


class A(models.Model):
    name = models.CharField(max_length=50)

class B(models.Model):
    a = models.ForeignKey(A)

filters.py

import rest_framework_filters as filters

from .models import B

class BFilter(filters.FilterSet):
    name = filters.AllLookupsFilter(name='a__name')
    working_name = filters.CharFilter(name='a__name')

    class Meta:
        model = B

Error when BFilter.name is in the code

>>> from testapp.filters import *
Traceback (most recent call last):
  File "<console>", line 1, in <module>

    raise FieldDoesNotExist('%s has no field named %r' % (self.object_name, field_name))
FieldDoesNotExist: B has no field named 'a__name'

There is no error BFilter.name is removed, i.e. BFilter.working_name does not have any problem with the related field.

pip freeze

Django==1.10.2
argparse==1.2.1
django-filter==0.15.3
djangorestframework==3.4.7
djangorestframework-filters==0.9.0
wsgiref==0.1.2

It seems like django_filters uses django_filters.utils.get_model_field to solve this issue,

This has been fixed on master.
