Installation

pip install django-htmx-admin

Add to your INSTALLED_APPS:

INSTALLED_APPS = [
    ...
    'django_htmx',
    'htmx_admin',
    ...
]

Add the middleware:

MIDDLEWARE = [
    ...
    'django_htmx.middleware.HtmxMiddleware',
    'htmx_admin.middleware.HtmxMessageMiddleware',
    ...
]

Usage

# admin.py
from django.contrib import admin
from htmx_admin import HtmxModelAdmin
from .models import Product

@admin.register(Product)
class ProductAdmin(HtmxModelAdmin):
    list_display = ['name', 'price', 'stock', 'category']

    # New HTMX features:
    list_editable_htmx = ['price', 'stock']  # Fields that can be edited inline
    list_filter_htmx = ['category']           # Filters that update without reload
    modal_fields = ['name', 'description', 'price']  # Fields to show in modal form

Configuration Options

HtmxModelAdmin Attributes

Attribute	Type	Description
list_editable_htmx	list[str]	Fields that can be edited inline
list_filter_htmx	list[str]	Filters that update without reload
modal_fields	list[str]	Fields to show in modal form

Admin Theme Support

django-htmx-admin automatically detects and adapts to your admin theme:

• Default Django Admin — Full support out of the box
• Grappelli — Automatic detection and themed templates

The package auto-detects which theme is installed and uses the appropriate templates and styling.

How It Works

django-htmx-admin uses HTMX to enhance Django Admin with partial page updates:

1. Inline Editing: Clicking an editable cell sends an HTMX GET request for the edit form, then POST to save.
2. Modal Forms: Add/Edit buttons trigger HTMX requests that load forms into a modal overlay.
3. Deletions: Delete buttons send HTMX DELETE requests and animate row removal.
4. Toast Messages: Server responses include HX-Trigger headers that display toast notifications.

Middleware

HtmxMessageMiddleware

Converts Django's messages framework messages to HTMX triggers for toast notifications.

HtmxRedirectMiddleware (optional)

Converts redirect responses to HX-Redirect headers for HTMX requests.

HtmxVaryHeaderMiddleware (optional)

Adds HX-Request to the Vary header for proper caching.

Mixins for Custom Views

You can use the provided mixins in your own views:

from htmx_admin.mixins import HtmxResponseMixin, HtmxFormMixin

class MyView(HtmxResponseMixin, View):
    def post(self, request):
        # Do something
        return self.htmx_response(
            status=204,
            showMessage={'level': 'success', 'message': 'Done!'}
        )

class MyFormView(HtmxFormMixin, FormView):
    form_class = MyForm
    template_name = 'my_form.html'
