django-chassis 1.0.15

A declarative, fully typed chassis for building polished Django Admin applications.

Documentation · Quick start · API reference · Changelog

Django-Chassis gives a project a structured AdminSite, composable ModelAdmin options, custom pages, dashboard contracts, and a complete template overlay. Domain models and business rules stay in the project; Chassis provides the reusable Admin application layer around them.

Features

• Declarative configuration — compose the Admin with ChassisAdminSiteMixin, ChassisAdminMixin, and immutable options.
• A polished changelist — search, filters, date hierarchy, tabs, badges, pretty JSON, and decimal-amount presentation without ad-hoc template forks.
• Row, list, and object actions — permission-aware buttons, confirmation, and condition methods.
• Related data — independently paginated tables and typed repeatable inputs with native or application-owned form-data processing.
• Custom pages — permission-aware pages, personal pages, information pages, and timelines.
• Dashboard contracts — metrics, charts, alerts, actions, a four-column grid, and live refresh at dashboard/live/.
• Import/export — JSON/XML in, JSON/XML/CSV/XLSX out, preview/apply, history, optional Celery.
• Users and security — profiles, sessions, login-attempt limits, GeoIP country detection, and an Admin audit journal.
• Fully typed — ships py.typed and is checked with Pyrefly in strict mode.

Installation

pip install django-chassis

Version 1.0.15 requires Python 3.13 or 3.14 and Django 6.0+.

Put 'django_chassis' before 'django.contrib.admin' so package templates overlay the stock Admin:

INSTALLED_APPS = [
    'django_chassis',
    'django.contrib.admin',
    # ...
]

Background import/export is optional:

pip install 'django-chassis[celery]'

For a production HTTP server, Chassis also provides a Gunicorn management command:

python manage.py run_gunicorn --port=8000 --workers=2

Quick start

Create a Chassis AdminSite, register a model, and mount the site in urls.py:

from django.contrib.admin import AdminSite, ModelAdmin
from django.urls import path
from django.utils.translation import gettext_lazy as _

from django_chassis.mixins import ChassisAdminMixin, ChassisAdminSiteMixin
from django_chassis.options import RowActionsOption, SearchOption

from catalog.models import Book


class CustomAdminSite(ChassisAdminSiteMixin, AdminSite):
    chassis_brand_name = _('My project')
    chassis_brand_logo_static_path = 'img/logo.png'


admin_site = CustomAdminSite(name='admin')


class BookAdmin(ChassisAdminMixin, ModelAdmin):
    options = [SearchOption(fields=['title', 'isbn']), RowActionsOption()]


admin_site.register(Book, BookAdmin)

urlpatterns = [path('admin/', admin_site.urls)]

ChassisAdminSiteMixin and ChassisAdminMixin must come before their Django classes in the MRO.
