Ajax autocomplete list filter for Django admin

django-admin-autocomplete-list-filter

Ajax autocomplete list filter helper for Django admin. Uses Django’s built-in autocomplete widget! No extra package or install required!

Installation and Usage

$ pip install django-admin-autocomplete-list-filter

Add djaa_list_filter to INSTALLED_APPS in your settings.py:

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'djaa_list_filter',           
]

Now, let’s look at this example model:

# models.py

from django.conf import settings
from django.db import models


class Post(models.Model):
    category = models.ForeignKey(to='Category', on_delete=models.CASCADE, related_name='posts')
    author = models.ForeignKey(to=settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='posts')
    title = models.CharField(max_length=255)
    body = models.TextField()
    tags = models.ManyToManyField(to='Tag', blank=True)

    def __str__(self):
        return self.title


class Category(models.Model):
    title = models.CharField(max_length=255)

    def __str__(self):
        return self.title


class Tag(models.Model):
    name = models.CharField(max_length=255)

    def __str__(self):
        return self.name

We have 2 ForeignKey fields and one ManyToManyField to enable autocomplete list filter feature on admin. All you need is to inherit from AjaxAutocompleteListFilterModelAdmin which inherits from Django’s admin.ModelAdmin.

Now we have an extra ModelAdmin method: autocomplete_list_filter. Uses Django Admin’s search_fields logic. You need to enable search_fields in the related ModelAdmin. To enable completion on Category relation, CategoryAdmin should have search_fields that’s it!

from django.contrib import admin

from djaa_list_filter.admin import (
    AjaxAutocompleteListFilterModelAdmin,
)

from .models import Category, Post, Tag


@admin.register(Post)
class PostAdmin(AjaxAutocompleteListFilterModelAdmin):
    list_display = ('__str__', 'author', 'show_tags')
    autocomplete_list_filter = ('category', 'author', 'tags')

    def show_tags(self, obj):
        return ' , '.join(obj.tags.values_list('name', flat=True))


@admin.register(Category)
class CategoryAdmin(admin.ModelAdmin):
    search_fields = ['title']
    ordering = ['title']


@admin.register(Tag)
class TagAdmin(admin.ModelAdmin):
    search_fields = ['name']
    ordering = ['name']
