  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

• Don’t count ManyToMany fields on a model as a field

• Remove common prefix checking.

• models.. specifying “objects = “ should be last

• Calling request.is_authenticated without actually calling function

• order_by(‘?’)

• request.method.upper is a no-op (etc.)

• cache.set without a timeout

• Unreversible urlpatterns

• Form class not in forms.py

• Admin class not in admin.py

• {% if foo %}{{ foo }}{% else %}bar{% endif %} => {{ foo|default:”bar” }}

• {% with foo as bar %} … [ not using {{ bar }} ] … {% endwith %}

• {% endblock %} vs. {% endblock blockname %}

• Ordering of MIDDLEWARE_CLASSES

• TEMPLATE_DIRS not absolute
