# 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!

![After](screenshots/demo.gif?v=2 "Widget in action...")

## Installation and Usage

```bash
$ pip install django-admin-autocomplete-list-filter2
```

Add `djaa_list_filter2` to `INSTALLED_APPS` in your `settings.py`:

```python
INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'djaa_list_filter2',           
]
```

Now, let’s look at this example model:

```python
# 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!

```python
from django.contrib import admin

from djaa_list_filter2.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']

```
