PolymorphicChildModelAdmin list displays base model of foreignkey fields

[variable]

I am aware of the polymorphic_list field in the PolymorphicParentModelAdmin, but I am using PolymorphicChildModelAdmin, and I am wondering if it's possible to display the relationship field to it's child class.

e.g

class Vote(Model):
  #  item can be "Content", "User" which extends "Trackable"
  item = Trackable(..)

When I display the admin list, the item is always displayed as "Trackable"

I'm not sure I get this.. You have a VoteAdmin or TrackableAdmin child? could you post a more complete example? the code you show clearly isn't Django model code, I'd expect it to be:

class Vote(models.Model):
    item = models.ForeignKey(Trackable)

@bckohan I think this should be a discussion

polymorphic_list only works on PolymorphicParentModelAdmin because it relies on a polymorphic queryset to resolve and display fields from different child models.

PolymorphicChildModelAdmin is already scoped to a single concrete child model and uses a non-polymorphic queryset, so there’s no equivalent mechanism to automatically display relationship fields that belong to other child classes.

You can display:

• fields defined on the child model itself, and
• fields defined on the parent model.

If you need to show data shared across multiple children, the recommended approach is to move that relationship to the parent model. Otherwise, the only workaround is a custom list_display method that manually accesses related objects, which is read-only and must be handled carefully.

This limitation is intentional and consistent with Django admin’s model isolation, not a missing feature in django-polymorphic.
