Django generic many-to-many field
Project description
© 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.* and 3.0.* and their matching Python versions (3.5 to 3.8).

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
Documentation
The documentation is hosted on readthedocs. You’ll find a quick start and the description of all django-gm2m’s advanced features.
