pep484 stubs for Django framework

This package contains type stubs and mypy plugin to provide more precise static types and type inference for Django framework. Django uses some Python "magic" that makes having precise types for some code patterns problematic. This is why we need to accompany the stubs with mypy plugins. The final goal is to be able to get precise types for most common patterns.

Supports Python 3.6/3.7, and Django 2.1/2.2.

Could be run on earlier versions of Django, but expect some missing imports warnings.

Installation

pip install django-stubs

WARNING: All configuration from pre-1.0.0 versions is dropped, use one below.

WARNING: 1.0.0 breaks dmypy, if you need it, stay on the 0.12.x series.

To make mypy aware of the plugin, you need to add

[mypy]
plugins =
    mypy_django_plugin.main

in your mypy.ini file.

Plugin requires Django settings module (what you put into DJANGO_SETTINGS_MODULE variable) to be specified inside mypy.ini file.

[mypy]
strict_optional = True

; this one is new
[mypy.plugins.django-stubs]
django_settings_module = mysettings

where mysettings is a value of DJANGO_SETTINGS_MODULE (with or without quotes)

New implementation uses Django runtime to extract models information, so it will crash, if your installed apps models.py is not correct. For this same reason, you cannot use reveal_type inside global scope of any Python file that will be executed for django.setup().

In other words, if your manage.py runserver crashes, mypy will crash too.
