django-more

A collection of Django patches and extensions to give more of the features and functionality that I want or expect from Django.
Currently aimed only at Django 1.11

django_more

django_more contains field and classes for Django that do not require any patching and can be used directly.

• django_more.storages
  Allows defining Django storages in settings and generating the storage classes as needed in django_more.storages.NAME.
• django_more.PartialIndex
  Database partial indexes using Django query and Q() notation.
  Working on postgres, untested elsewhere.
• django_more.HashField
  Field for storing hashes and removing the issues with comparing, generating, and converting hashes.
• django_more.OrderByField (requires django_types)
  Field for order_with_respect_to similar functionality, with support for an arbitrary number of fields in the ordering, database constraints, bulk updates, single query creation, and generic keys.

Placing django_more into Django INSTALLED_APPS will automatically invoke django_types.patch_types() - only necessary for OrderByField makemigrations

django_enum

django_enum patches Django to add EnumFields, with enum state information in migrations to allow for consistent migrations compatible with postgres and mysql.

• django_enum.EnumField (requires django_types)
  Django field based upon python 3.4 (PEP435) Enum with support for database enum fields.
• django_enum.enum_meta
  Decorator to hide Meta classes in standard python Enum.
• django_enum.patch_enum()
  Applies patches to Django necessary for this module to work.

Placing django_enum into Django INSTALLED_APPS will automatically invoke patch_enum() and django_types.patch_types()

django_types

django_types patches Django to add support for custom database types to be used within migrations.
Not intended to be used directly, but by other reusable apps adding fields that rely on the additional functionality.

• django_types.CustomTypeField
  Base implementation for custom types that can be managed within the migration framework.
• django_types.patch_types()
  Applies patches to Django necessary for this module to work.

Apps dependent on this should check for ProjectState.add_type() support, and if not present apply this with patch_types()

django_cte

django_cte patches Django to add CTE based functionality.

• django_cte.patch_cte()
  Applies patches to Django necessary for this module to work.

Not included in distributions until out of WIP state
Placing django_cte into Django INSTALLED_APPS will automatically invoke patch_cte()

patchy

patchy is class based monkey patching package used by the other django-more modules to apply their patches in a consistent and safe manner that is hopefully less fragile to Django core changes.

• patchy.patchy()
  Creates a class and context manager to apply patches.
• patchy.super_patchy()
  Provides functionality similar to super() to functions and methods that have been patched in, allowing calls the methods they replaced.
