Quick Start

pip install django-i18n-fields

# With Markdown editor support (martor)
pip install django-i18n-fields[md]

# models.py
from django.db import models
from i18n_fields import LocalizedCharField, LocalizedTextField

class Article(models.Model):
    title = LocalizedCharField(max_length=200, required=['en'])
    content = LocalizedTextField(blank=True)

# Create with translations
article = Article.objects.create(
    title={'en': 'Hello World', 'es': 'Hola Mundo'},
    content={'en': 'Content in English', 'es': 'Contenido en español'}
)

# Access in current language
print(article.title)  # Automatically uses active language

# Query by specific language
Article.objects.filter(title__en='Hello World')

# Order by translated field
from i18n_fields import L
Article.objects.order_by(L('title'))

# admin.py - Option 1: Using the base class (recommended)
from i18n_fields import LocalizedFieldsAdmin

@admin.register(Article)
class ArticleAdmin(LocalizedFieldsAdmin):
    list_display = ['title', 'created_at']
    # Automatic tab/dropdown widgets for all localized fields!

# admin.py - Option 2: Using the mixin with your own base class
from django.contrib import admin
from i18n_fields import LocalizedFieldsAdminMixin

@admin.register(Article)
class ArticleAdmin(LocalizedFieldsAdminMixin, admin.ModelAdmin):
    list_display = ['title', 'created_at']

# serializers.py
from i18n_fields.drf import LocalizedModelSerializer

class ArticleSerializer(LocalizedModelSerializer):
    class Meta:
        model = Article
        fields = ['id', 'title', 'content']

# Returns: {"id": 1, "title": "Hello World", "content": "..."}
# Automatically uses active language!

# settings.py
INSTALLED_APPS = [
    # ...
    'i18n_fields',
]

LANGUAGES = [
    ('en', 'English'),
    ('es', 'Spanish'),
    ('fr', 'French'),
]

I18N_FIELDS = {
    'DISPLAY': 'tab',  # or 'dropdown' for admin
    'FALLBACKS': {
        'en-us': ['en'],
        'es-mx': ['es'],
    },
}
