How django-moderation works
When you change existing object or create new one, it will not be publicly available until moderator approves it. It will be stored in ModeratedObject model.
your_model = YourModel(description='test') your_model.save() YourModel.objects.get(pk=your_model.pk) Traceback (most recent call last): DoesNotExist: YourModel matching query does not exist.
When you will approve object, then it will be publicly available.
your_model.moderated_object.approve(moderatated_by=user, reason='Reason for approve') YourModel.objects.get(pk=1) <YourModel: YourModel object>
You can access changed object by calling changed_object on moderated_object:
your_model.moderated_object.changed_object <YourModel: YourModel object>
This is deserialized version of object that was changed.
Now when you will change an object, old version of it will be available publicly, new version will be saved in moderated_object
your_model.description = 'New description' your_model.save() your_model = YourModel.objects.get(pk=1) your_model.__dict__ {'id': 1, 'description': 'test'} your_model.moderated_object.changed_object.__dict__ {'id': 1, 'description': 'New description'} your_model.moderated_object.approve(moderatated_by=user, reason='Reason for approve') your_model = YourModel.objects.get(pk=1) your_model.__dict__ {'id': 1, 'description': 'New description'}
Email notifications
By default when user change object that is under moderation, e-mail notification is send to moderator. It will inform him that object was changed and need to be moderated.
When moderator approves or reject object changes then e-mail notification is send to user that changed this object. It will inform user if his changes were accepted or rejected and inform him why it was rejected or approved.
How to overwrite email notification templates
E-mail notifications use following templates:
- moderation/notification_subject_moderator.txt
- moderation/notification_message_moderator.txt
- moderation/notification_subject_user.txt
- moderation/notification_message_user.txt
Default context:
content_type - content type object of moderated object
moderated_object - ModeratedObject instance
site - current Site instance
How to pass extra context to email notification templates
If you want to pass extra context to email notification methods you new need to create new class that subclass BaseModerationNotification class.
class CustomModerationNotification(BaseModerationNotification): def inform_moderator(self, subject_template='moderation/notification_subject_moderator.txt', message_template='moderation/notification_message_moderator.txt', extra_context=None): '''Send notification to moderator''' extra_context={'test':'test'} super(CustomModerationNotification, self).inform_moderator(subject_template, message_template, extra_context) def inform_user(self, user, subject_template='moderation/notification_subject_user.txt', message_template='moderation/notification_message_user.txt', extra_context=None) '''Send notification to user when object is approved or rejected''' extra_context={'test':'test'} super(CustomModerationNotification, self).inform_user(user, subject_template, message_template, extra_context)
Next register it with moderation as notification_class:
moderation.register(YourModel, notification_class=CustomModerationNotification)
Signals
moderation.signals.pre_moderation - signal send before object is approved or rejected
Arguments sent with this signal:
sender - The model class.
instance - Instance of model class that is moderated
status - Moderation status, 0 - rejected, 1 - approved
moderation.signals.post_moderation - signal send after object is approved or rejected
Arguments sent with this signal:
sender - The model class.
instance - Instance of model class that is moderated
status - Moderation status, 0 - rejected, 1 - approved
Forms
When creating ModelForms for models that are under moderation use BaseModeratedObjectForm class as ModelForm class. Thanks to that form will initialized with data from changed_object.
from moderation.forms import BaseModeratedObjectForm class ModeratedObjectForm(BaseModeratedObjectForm): class Meta: model = MyModel
