9730	When using model inheritance, raw_id_fields returns a model's name in the input field.	grantmoney	Malcolm Tredinnick	"# Parent Model
{{{
from django.db import models

class Place(models.Model):
    name = models.CharField(max_length=99)
    description = models.CharField(max_length=400, blank=True)
}}}

# Child Models
{{{
class Country(Place):
    place = models.OneToOneField(Place, primary_key=True, parent_link=True, related_name='place_country')

class City(Place):
    place = models.OneToOneField(Place, primary_key=True, parent_link=True, related_name='place_city')
    country = models.ForeignKey(Country, related_name='city_country')
}}}

# Admin
{{{
from django.contrib import admin

class CityOptions(admin.ModelAdmin):
    raw_id_fields = ('country',)

admin.site.register(Place)
admin.site.register(Country)
admin.site.register(City, CityOptions)
}}}

# Description
First we start with a base model named Place, and then set up 2 Child models (Country and City in this case).

If we then use raw_id_fields for a ForeignKey to a model that inherits from the base model, instead of returning the model's pk/id, it instead returns the name of the object.

{{{
# First we create a Country
country, x = Country.objects.get_or_create(name=""America"")
}}}

If we now try to add a City using Django's admin, when selecting the country (which when using raw_id_fields is done via a pop up browser window), the input field will be given a value of ""America"" instead of the object's pk which in this case would be 1.

Going through where this might have started to occur, it seems to have started with the changes to ForeignKeyRawIdWidget in [8823]."		closed	contrib.admin	1.0		duplicate			Unreviewed	0	0	0	0	0	0
