Tool to lint Django applications and projects

django-lint

Ideas

• Default manager with restrictive get_query_set()
• Oldforms (?)

• Overring definition of model. Eg:

  class MyModel(models.Model):

  foo = [..]

  foo = [..]

• Not importing settings via "django.conf import settings"
• Not using reverse (or @permalink) in get_absolute_url (?)
• Form definitions in models.py
• Ignore tests

Models

• Don't count ManyToMany fields on a model as a field
• Remove common prefix checking.
• models.. specifying "objects = " should be last

Views

• Calling request.is_authenticated without actually calling function
• order_by('?')
• request.method.upper is a no-op (etc.)
• cache.set without a timeout

URLS

• Unreversible urlpatterns

Layout

• Form class not in forms.py
• Admin class not in admin.py

Templates

• {% if foo %}{{ foo }}{% else %}bar{% endif %} => {{ foo|default:"bar" }}
• {% with foo as bar %} ... [ not using {{ bar }} ] ... {% endwith %}
• {% endblock %} vs. {% endblock blockname %}

Settings

• Ordering of MIDDLEWARE_CLASSES
• TEMPLATE_DIRS not absolute

Layout

forms not in forms.py managers not in managers.py
