9863	InlineModelAdmin breaks in the latest revision 9650	shilin	Keith Bussell	"I've defined two models like this:

{{{

class Parent(models.Model):    
    name = models.CharField(max_length = 128, db_index = True)    

class Child(models.Model):    
    parent = models.ForeignKey(Parent, related_name = 'child_set', editable = False)
    name = models.CharField(max_length = 30, blank = True)    

}}}

And in admin.py, I tried to edit the Child object related to the certain Parent object.


{{{

class ChildInline(admin.StackedInline):
    model = Child
    extra = 10

class ParentAdmin(admin.ModelAdmin):    
    inlines = [
       ChildInline,     
    ]

site.register(Parent, ParentAdmin)

}}}


However, the admin application shows something like below:

{{{
KeyError at /admin/object/object/add/

'object'
}}}

The line of code which throws the exception is

{{{
C:\Python24\lib\site-packages\django\forms\models.py in add_fields

 487. return save_instance(form, new_obj, exclude=[self._pk_field.name], commit=commit)
 488.
 489. def add_fields(self, form, index):
 490. super(BaseInlineFormSet, self).add_fields(form, index)
 491. if self._pk_field == self.fk:
 492. form.fields[self._pk_field.name] = InlineForeignKeyField(self.instance, pk_field=True)
 493. else:

 >>>This Line>>> 494. form.fields[self.fk.name] = InlineForeignKeyField(self.instance, label=form.fields[self.fk.name].label) ...

}}}

I've tried to revert my Django to revision 9160, the same model and admin settings do not throw the same exception. It's like that the foreignkey field leads to this error.
But I'm quite confused about it.
