django-pylint is a Pylint plugin for improving code analysis for when analysing code using Django. This package is a currently maintained fork of pylint-django!

Ensure django-pylint is installed and on your path (pip install django-pylint), and then run pylint:

pylint --load-plugins pylint_django [..other options..]

• Prevents warnings about Django-generated attributes such as Model.objects or Views.request.
• Prevents warnings when using ForeignKey attributes ("Instance of ForeignKey has no member").
• Fixes pylint's knowledge of the types of Model and Form field attributes
• Validates Model.__unicode__ methods.
• Meta informational classes on forms and models do not generate errors.

The structure of the test package follows that from pylint itself.

It is fairly simple: create a module starting with func_ followed by a test name, and insert into it some code. The tests will run pylint against these modules. If the idea is that no messages now occur, then that is fine, just check to see if it works by running scripts/test.sh.

Ideally, add some pylint error suppression messages to the file to prevent spurious warnings, since these are all tiny little modules not designed to do anything so there's no need to be perfect.

It is possible to make tests with expected error output, for example, if adding a new message or simply accepting that pylint is supposed to warn. Add a .txt file which should match the name of the test and contains error type, line number, class and expected text. The test code itself should also be annotated with comments on lines which are supposed to trigger pylint messages! See func_model_does_not_use_unicode_py33 for example!
