Settings¶
The following settings can be added to your project’s settings.py file to customise the behaviour of Djem features.
DJEM_COMMON_INFO_REQUIRE_USER_ON_SAVE¶
New in version 0.4.
Default: True
By default, the save() method of CommonInfoMixin and the update() method of CommonInfoQuerySet require their first positional argument to be a User instance, so they can automatically set the user_created and/or user_modified fields that CommonInfoMixin provides. This behaviour can cause issues if you are using third party code that calls the save method of a model instance or the update method of a queryset, as it will not pass this required argument.
Djem provides CommonInfoForm to enable Django ModelForms to work with models making use of CommonInfoMixin. But if you can’t use similar wrappers around other third party code invoking these methods, this setting can help.
Setting DJEM_COMMON_INFO_REQUIRE_USER_ON_SAVE to False removes the “required” nature of the user argument to save()/update(). It will still be accepted, and will still be used as per usual if it is provided. But if it is not provided, no exception will be raised, and the fields that would ordinarily be populated by it will simply be left alone.
Warning
The user_created and user_modified fields will still be required. When creating instances of models using CommonInfoMixin, and a User is not passed to the save() method, these fields will need to be populated manually, or an IntegrityError will be raised.
Warning
Using this setting can reduce the accuracy of user_modified, as it is no longer guaranteed to be updated by any save/update to the model instance. It will be up to you to ensure that this field is updated when necessary.
DJEM_DEFAULT_403¶
New in version 0.5.
Default: False
Specifies the default behaviour of the permission_required() decorator and djem.auth.PermissionRequired class-based view mixin when a user does not have the specified permission/s. If True, the PermissionDenied exception will be raised, invoking the 403 handler. If False, the user will be redirected to the appropriate login url.
This affects default behaviour only - individual uses of permission_required() and djem.auth.PermissionRequired can customise it.
DJEM_DEFAULT_PAGE_LENGTH¶
New in version 0.5.
Default: None
The default page length to use for the djem.pagination.get_page() helper function. Adding this setting removes the need to provide a page length argument to every djem.pagination.get_page() call. See Controlling page length for more details.
DJEM_FORM_FIELD_TAG¶
New in version 0.6.
Default: ‘div’
The HTML tag to use for the wrapping element rendered around form fields when using the form_field or checkbox template tags.
