Custom list display of model timestamps for Django Admin.

Project description

Show human readable created/modified dates and/or times in the django.contrib.admin changelist for models that track the moment of creation and updates.


First you will need to have a model that tracks the moment of creation and modification. The barebones example for that is:

from django.db import models

class TimestampedItem(models.Model):
    created = models.DateTimeField('created', auto_now_add=True)
    modified = models.DateTimeField('modified', auto_now=True)

Or, if you are using django-extensions:

from django_extensions.db.models import TimeStampedModel

class TimestampedItem(TimeStampedModel):

Now it’s time to register this model with Django’s admin site.

Create a admin class, just like you’d usually do, but make it extend TimestampedAdminMixin as well as any other base admin class you use:

from django.contrib import admin
from models import TimestampedItem
from admintimestamps import TimestampedAdminMixin

class TimestampedAdmin(TimestampedAdminMixin, admin.ModelAdmin):
    pass, TimestampedAdmin)

That’s it!


If the names of you timestamp fields aren’t created and modified but for example created_at and modified_at you’ll need to do a tiny bit of configuration in the model admin class:

class TimestampedAdmin(TimestampedAdminMixin, admin.ModelAdmin):
    timestamp_fields = ('created_at', 'modified_at')

You can also use the timestamp_fields tuple to only show one field by only specifying the field you want to show:

class TimestampedAdmin(TimestampedAdminMixin, admin.ModelAdmin):
    timestamp_fields = ('modified',)
