set_unusable_password() Marks the user as having no password set. This isn’t the same as having a blank string for a password. check_password() for this user will never return True.

class UserAttributeSimilarityValidator(user_attributes=DEFAULT_USER_ATTRIBUTES, max_similarity=0.7) [source] Validates whether the password is sufficiently different from certain attributes of the user.

ModelAdmin.get_formsets_with_inlines(request, obj=None) [source] Yields (FormSet, InlineModelAdmin) pairs for use in admin add and change views.

django.template.Library.filter() Once you’ve written your filter definition, you need to register it with your Library instance, to make it available to Django’s template language: register.filter('cut', cut) register.filter('lower', lower) The Library.filter() method takes two arguments: The name of the filter – a string. The compilation function – a Python function (not the name of the function as a string). You can use register.filter() as a decorator instead: @register.filter(name='cu
