django-subquery

Backport of https://docs.djangoproject.com/en/dev/ref/models/expressions/#subquery-expressions to support legacy Django versions.

Installation:

$ pip install django-subquery

Usage:

Please see the official Django documentation: https://docs.djangoproject.com/en/dev/ref/models/expressions/#subquery-expressions

Note that you need to import from django_subquery.expressions instead of django.db.models.

Supported versions:

This package is in production use with Django 1.8, but should work with any version of Django from 1.8 onwards.

Unsupported features:

This package is not likely to work on Oracle, as that required some backend within django to work.

Upgrading from < 1.0

The main class used to be called SubQuery, but was renamed Subquery when merged into Django 1.11.

You'll need to adjust your code accordingly.
