Hi I have a shopping cart application, where by each cart can hold several kinds of objects, I have therefore used generic relations to model the application along the lines of below, whereby each cart can have many cartitems which are linked by a standard foreign key relationship, the cartitems are in turn linked to the individual item models by a GenericForeignKey:
class Cart(models.Model): invoice = models.PositiveIntegerField(max_length=50, null=True, unique=True) datetime_added = models.DateTimeField(auto_now_add=True) ....etc class CartItem(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') cart = models.ForeignKey(Cart, related_name="items") class AccessoryOrder(models.Model): cart_item = generic.GenericRelation(CartItem) class BikePart(UsedItem): partType = models.ForeignKey(PartType) cart_item = generic.GenericRelation(CartItem) class UsedBike(UsedItem): bike = models.ForeignKey(Bike) cart_item = generic.GenericRelation(CartItem) This works fine, but I can't figure out a way to get what I want in the admin app. I have created the AccessoryOrderInline class subclassing GenericStackedInline, but the inlines don't work in reverse even where you have added the generic.GenericRelation attribute to the model. The relevant parts of admin.py are: class AccessoryOrderInline(generic.GenericStackedInline): model = AccessoryOrder class CartItemInline(admin.StackedInline): model = CartItem exclude = ('content_type', 'object_id') extra = 0 fields = ('content.object',) inlines = [ AccessoryOrderInline, ] class CartAdmin(admin.ModelAdmin): date_hierarchy = 'datetime_added' form = CartForm inlines = [ CartItemInline, ] The issue is that when I click on a cart to view in admin, I the CartItem objects but not the Accessory objects themselves, or any other types of item. With the model design the way it is, I don't see a way of getting the admin app to do what I want, so is my model design flawed and is there a better way of doing this using generic relations.
