django-gm2m 1.3

Django generic many-to-many field

© 2014-2020 Thomas Khyn

Django generic many-to-many field implementation.

This django application exposes a GM2MField that combines the features of the standard Django ManyToManyField and GenericForeighKey and that can be used exactly the same way.

It has been tested with Django 2.2.*, 3.0.*, 3.1.*, 3.2.*, 4.0.*, 4.1.*, 4.2.*, 5.0.*, 5.1.*, 5.2.* and their compatible Python versions (3.8 to 3.13).

Features

• Works like the built-in Django related fields

• Creates one table per relation, like ManyToManyField, and not one big table linking anything to anything (django-generic-m2m’s default approach)

• No need to modify nor monkey-patch the existing model classes that need to be linked

• Automatic reverse relations when an instance is added

• Related objects prefetching

• Through models support

• Deletion behaviour customization using signals

• Migrations support
