Getting started quick guide

Installation

$ pip install django-moderation

Or download source code from http://github.com/dominno/django-moderation and run installation script:

$ python setup.py install

Configuration

django-moderation will autodiscover moderation classes in <app>/moderator.py files by default. So the simplest moderation configuration is to simply add moderation (or moderation.apps.ModerationConfig) to INSTALLED_APPS in your settings.py:

INSTALLED_APPS = [
    # ...
    'moderation',  # or 'moderation.apps.ModerationConfig',
    # ...
]

Then add all of your moderation classes to a moderator.py file in an app and register them with moderation:

from moderation import moderation
from moderation.moderator import GenericModerator

from yourapp.models import YourModel, AnotherModel


class AnotherModelModerator(GenericModerator):
    # Add your moderator settings for AnotherModel here


moderation.register(YourModel)  # Uses default moderation settings
moderation.register(AnotherModel, AnotherModelModerator)  # Uses custom moderation settings

This is exactly how Django’s contributed admin app registers models.

Alternative Configuration

If you don’t want django-moderation to autodiscover your moderation classes, you will add moderation.apps.SimpleModerationConfig to INSTALLED_APPS in your settings.py:

INSTALLED_APPS = [
    # ...
    'moderation.apps.SimpleModerationConfig',
    # ...
]

Then you will need to subclass your models from moderation.db.ModeratedModel and add moderation classes to each moderated model in models.py:

from django.db import models
from moderation.db import ModeratedModel


class MyModel(ModeratedModel):
    my_field = models.TextField()

    class Moderator:
        notify_user = False

Admin integration

  1. If you want to enable integration with Django Admin, then register admin class with your model:
from django.contrib import admin
from moderation.admin import ModerationAdmin


class YourModelAdmin(ModerationAdmin):
    """Admin settings go here."""

admin.site.register(YourModel, YourModelAdmin)

If admin_integration_enabled is enabled then when saving object in admin, data will not be saved in model instance but it will be stored in moderation queue. Also data in the change form will not display data from the original model instance but data from the ModeratedObject instance instead.

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(by=user, reason='Reason for approve')

YourModel.objects.get(pk=1)
<YourModel: YourModel object>

Please note that you can also access objects that are not approved by using unmoderated_objects manager, this manager will bypass the moderation system

YourModel.unmoderated_objects.get(pk=your_model.pk)

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(by=user, reason='Reason for approve')

your_model = YourModel.objects.get(pk=1)
your_model.__dict__
{'id': 1, 'description': 'New description'}
