Version 0.9.2 (2016-05-04)

  • Fix error when using date_hierarchy field in the admin
  • Fixed Django 1.10 warning in admin add-type view.

Version 0.9.1 (2016-02-18)

  • Fixed support for PolymorphicManager.from_queryset() for custom query sets.
  • Fixed Django 1.7 changeform_view() redirection to the child admin site. This fixes custom admin code that uses these views, such as django-reversion‘s revision_view() / recover_view().
  • Fixed .only('pk') field support.
  • Fixed object_history_template breadcrumb. NOTE: when using django-reversion / django-reversion-compare, make sure to implement a admin/polymorphic/object_history.html template in your project that extends from reversion/object_history.html or reversion-compare/object_history.html respectively.

Version 0.9 (2016-02-17)

  • Added .only() and .defer() support.
  • Added support for Django 1.8 complex expressions in .annotate() / .aggregate().
  • Fix Django 1.9 handling of custom URLs. The new change-URL redirect overlapped any custom URLs defined in the child admin.
  • Fix Django 1.9 support in the admin.
  • Fix missing history_view() redirection to the child admin, which is important for django-reversion support. See the documentation for hints for django-reversion-compare support.

Version 0.8.1 (2015-12-29)

  • Fixed support for reverse relations for relname___field when the field starts with an _ character. Otherwise, the query will be interpreted as subclass lookup (ClassName___field).

Version 0.8 (2015-12-28)

  • Added Django 1.9 compatibility.
  • Renamed polymorphic.manager => polymorphic.managers for consistentcy.
  • BACKWARDS INCOMPATIBILITY: The import paths have changed to support Django 1.9. Instead of from polymorphic import X, you’ll have to import from the proper package. For example:
from polymorphic.models import PolymorphicModel
from polymorphic.managers import PolymorphicManager, PolymorphicQuerySet
from polymorphic.showfields import ShowFieldContent, ShowFieldType, ShowFieldTypeAndContent
  • BACKWARDS INCOMPATIBILITY: Removed in favor of a standard __version__ in polymorphic/
  • BACKWARDS INCOMPATIBILITY: Removed automatic proxying of method calls to the queryset class. Use the standard Django methods instead:
# In model code:
objects = PolymorphicQuerySet.as_manager()

# For manager code:
MyCustomManager = PolymorphicManager.from_queryset(MyCustomQuerySet)

Version 0.7.2 (2015-10-01)

  • Added queryset.as_manager() support for Django 1.7/1.8
  • Optimize model access for non-dumpdata usage; avoid __getattribute__() call each time to access the manager.
  • Fixed 500 error when using invalid PK’s in the admin URL, return 404 instead.
  • Fixed possible issues when using an custom AdminSite class for the parent object.
  • Fixed Pickle exception when polymorphic model is cached.

Version 0.7.1 (2015-04-30)

  • Fixed Django 1.8 support for related field widgets.

Version 0.7 (2015-04-08)

  • Added Django 1.8 support
  • Added support for custom primary key defined using mybase_ptr = models.OneToOneField(BaseClass, parent_link=True, related_name="...").
  • Fixed Python 3 issue in the admin
  • Fixed _default_manager to be consistent with Django, it’s now assigned directly instead of using add_to_class()
  • Fixed 500 error for admin URLs without a ‘/’, e.g. admin/app/parentmodel/id.
  • Fixed preserved filter for Django admin in delete views
  • Removed test noise for diamond inheritance problem (which Django 1.7 detects)

Version 0.6.1 (2014-12-30)

  • Remove Django 1.7 warnings
  • Fix Django 1.4/1.5 queryset calls on related objects for unknown methods. The RelatedManager code overrides get_query_set() while __getattr__() used the new-style get_queryset().
  • Fix validate_model_fields(), caused errors when metaclass raises errors

Version 0.6 (2014-10-14)

  • Added Django 1.7 support.
  • Added permission check for all child types.
  • BACKWARDS INCOMPATIBILITY: the get_child_type_choices() method receives 2 arguments now (request, action). If you have overwritten this method in your code, make sure the method signature is updated accordingly.

Version 0.5.6 (2014-07-21)

  • Added pk_regex to the PolymorphicParentModelAdmin to support non-integer primary keys.
  • Fixed passing ?ct_id= to the add view for Django 1.6 (fixes compatibility with django-parler).

Version 0.5.5 (2014-04-29)

  • Fixed get_real_instance_class() for proxy models (broke in 0.5.4).

Version 0.5.4 (2014-04-09)

  • Fix .non_polymorphic() to returns a clone of the queryset, instead of effecting the existing queryset.
  • Fix missing alters_data = True annotations on the overwritten save() methods.
  • Fix infinite recursion bug in the admin with Django 1.6+
  • Added detection of bad ContentType table data.

Version 0.5.3 (2013-09-17)

  • Fix TypeError when base_form was not defined.
  • Fix passing /admin/app/model/id/XYZ urls to the correct admin backend. There is no need to include a ?ct_id=.. field, as the ID already provides enough information.

Version 0.5.2 (2013-09-05)

  • Fix Grappelli breadcrumb support in the views.
  • Fix unwanted ___ handling in the ORM when a field name starts with an underscore; this detects you meant relatedfield__ _underscorefield instead of ClassName___field.
  • Fix missing permission check in the “add type” view. This was caught however in the next step.
  • Fix admin validation errors related to additional non-model form fields.

Version 0.5.1 (2013-07-05)
