dalf 0.2.2

Dead simple autocompletion for Django admin list_filter with goodies.

Django Admin List Filter

Dead simple autocompletion for Django admin list_filter. This was made using the libraries shipped with Django (select2, jquery), Django’s built-in list filters, and Django’s built-in AutocompleteJsonView.

This package is an improved version of the previously created django-admin-autocomplete-list-filter package. It supports Django version 5 and above. Please note that the django-admin-autocomplete-list-filter package is now deprecated. Since I am no longer part of the organization where it was initially developed, I cannot archive it.

No extra package or install required!

Thanks to my dear friend Bahattin Çiniç’s warning, He realized that the necessary HTML, CSS, and JavaScript files were missing from the published package! I quickly fixed this and published a new version. The 0.1.0 version is a faulty version. I apologize to the users for this confusion. Thank you. - vigo

Usage

Use DALFModelAdmin, inherited from admin.ModelAdmin to inject media urls only. You have some filters;

• DALFRelatedField: inherited from admin.RelatedFieldListFilter.
• DALFRelatedFieldAjax: inherited from admin.RelatedFieldListFilter
• DALFRelatedOnlyField: inherited from admin.RelatedOnlyFieldListFilter.
• DALFChoicesField: inherited from admin.ChoicesFieldListFilter.

Example models.py

# models.py
import uuid

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


class Category(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    title = models.CharField(max_length=255)

    def __str__(self):
        return self.title


class Tag(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    name = models.CharField(max_length=255)

    def __str__(self):
        return self.name


class Post(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    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

Example admin.py:

# admin.py
from dalf.admin import DALFModelAdmin, DALFRelatedOnlyField, DALFRelatedFieldAjax
from django.contrib import admin
from YOURAPP.models import Post

@admin.register(Post)
class PostAdmin(DALFModelAdmin):
    list_filter = (
        ('author', DALFRelatedOnlyField),    # if author has a post!
        ('category', DALFRelatedFieldAjax),  # enable ajax completion for category field (FK)
        ('tags', DALFRelatedFieldAjax),      # enable ajax completion for tags field (M2M)
    )

That’s all... There is also DALFChoicesField, you can test it out:

# admin.py
from django.contrib import admin
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
from django.contrib.auth.models import User

from dalf.admin import (
    DALFModelAdmin,
    DALFChoicesField,
    DALFRelatedOnlyField,
    DALFRelatedFieldAjax,
)

from YOURAPP.models import Post, Category, Tag

# must be registered, must have search_fields, required for `author` field demo.
# this is demo purpose only, you can register/import your own/custom User model
class UserAdmin(BaseUserAdmin):
    search_fields = ['username']
    ordering = ['username']

admin.site.unregister(User)
admin.site.register(User, UserAdmin)

@admin.register(Post)
class PostAdmin(DALFModelAdmin):
    list_filter = (
        ('author', DALFChoicesField),        # enable autocomplete w/o ajax (FK)
        ('category', DALFRelatedFieldAjax),  # enable ajax completion for category field (FK)
        ('tags', DALFRelatedOnlyField),      # enable ajax completion for tags field (M2M) if posts has any tag!
    )

# must be registered, must have search_fields
@admin.register(Category)
class CategoryAdmin(admin.ModelAdmin):
    search_fields = ['title',]
    ordering = ['title']


# must be registered, must have search_fields
@admin.register(Tag)
class TagAdmin(admin.ModelAdmin):
    search_fields = ['name',]
    ordering = ['name']

Extras

I mostly use django-timezone-field, here is an illustration of timezone completion w/o ajax:

pip install django-timezone-field

Now add timezone field to Post model:

# modify models.py, add new ones
# ...

from timezone_field import TimeZoneField                 # <- add this line

class Post(models.Model):
    # all the other fiels
    timezone = TimeZoneField(default=settings.TIME_ZONE) # <- add this line
    
    # rest of the code

Now, just add timezone as regular list_filter:

# modify admin.py, add new ones

@admin.register(Post)
class PostAdmin(DALFModelAdmin):
    # previous codes
    list_filter = (
        # previous filters
        ('timezone', DALFChoicesField), # <- add this line
    )

That’s it!
