Django admin widget GenericForeignKey

Question

I am creating a Django application where all models can be connected to each other in the order specified by the user. I customize all this using GenericForeignKeys. A kicker is what I need to be able to support multiple collections of these types of / admin relationships. Thus, a single object may have more than one set of related objects.

Does anyone know a good GenericForeignKey widget for this situation? Preferably, it will be an autocomplete search that fills out the administrative form, as I can end up with a large number of objects.

Here is the code for my application to better understand what I mean.

from django.contrib import admin from django.contrib.contenttypes import generic from django.contrib.contenttypes.models import ContentType from django.db import models from django import forms # Models class Base(models.Model): title = models.CharField(max_length=255) class Meta: abstract = True def __unicode__(self): return self.title class Related(Base): """ A generic relationship model for relating resources. """ order = models.IntegerField(blank=True, null=True) limit = models.Q(model = 'Apple') | models.Q(model = 'Orange') | models.Q(model = 'Pear') content_type = models.ForeignKey(ContentType, related_name="related_%(class)s") object_id = models.PositiveIntegerField(db_index=True) object = generic.GenericForeignKey() related_content_type = models.ForeignKey(ContentType, related_name="related_related_%(class)s", limit_choices_to = limit) related_object_id = models.PositiveIntegerField(db_index=True) related_object = generic.GenericForeignKey('related_content_type', 'related_object_id') class Meta: ordering = ('order',) abstract = True def __unicode__(self): return self.object.title class FreshFruit(Related): pass class OldFruit(Related): pass class Apple(Base): pass class Orange(Base): pass class Pear(Base): pass # Admin classes class FreshFruitInline(generic.GenericStackedInline): model = FreshFruit extra = 1 # Admin classes class OldFruitInline(generic.GenericStackedInline): model = OldFruit extra = 1 class AppleAdmin(admin.ModelAdmin): inlines = [FreshFruitInline, OldFruitInline,] admin.site.register(Apple, AppleAdmin) class OrangeAdmin(admin.ModelAdmin): inlines = [FreshFruitInline, OldFruitInline,] admin.site.register(Orange, OrangeAdmin) class PearAdmin(admin.ModelAdmin): inlines = [FreshFruitInline, OldFruitInline,] admin.site.register(Pear, PearAdmin) 

I searched and searched and found widgets that do this for ManyToMany relationships, but nothing for my situation.

Thanks for taking the time to look at this.

Look at the generic Grappelli foreign key widget that works well: django-grappelli / generic_2_2
