django-admin-blame

django-admin-blame is a Django app providing mixins for tracking date and author of model changes from django admin.

Description

Often it is useful to know date and author of object creation or modification. django-admin-blame provides a django model mixin with fields:

• created (datetime) - timestamp of object creation
• created_by (FK to User) - reference to an admin user who created this object through admin site
• modified (datetime) - timestamp of last object modification
• modified_by (FK to User) - reference to an admin user who made last changes to this object through admin site. If changes has been made somewhere else, field value is reset to None.

Installation

pip install django-admin-blame

Working example is in testproject.testapp.

1. Enable middleware in django settings:

   MIDDLEWARE.append('admin_log.middleware.AdminLogMiddleware')
   

2. Add model mixin to your models:

   from django.db import models
   
   from admin_log.models import AdminLogMixin
   
   
   class Subject(AdminLogMixin, models.Model):
       title = models.CharField(max_length=50)
       content = models.TextField()
   

3. Add admin mixin to corresponding model admin:

   from django.contrib import admin
   
   from admin_log.admin import AdminLogMixin
   from testproject.testapp import models
   
   
   @admin.register(models.Subject)
   class SubjectAdmin(AdminLogMixin, admin.ModelAdmin):
       pass
   

Now you have readonly fields with date and author of last revision in admin "edit" page.
