Easily translate "cheese omelet" into "omelette au fromage".








Simple Django model translations without nasty hacks.


  • Nice admin integration.
  • Access translated attributes like regular attributes.
  • Automatic fallback to the default language.
  • Separate table for translated fields, compatible with django-hvad.
  • Plays nice with others, compatible with django-polymorphic, django-mptt and such:
    • No ORM query hacks.
    • Easy to combine with custom Manager or QuerySet classes.
    • Easy to construct the translations model manually when needed.

See the documentation for more details.

A brief overview

Installing django-parler

The package can be installed using:

pip install django-parler

Add the following settings:


Optionally, the admin tabs can be configured too:

    None: (
        {'code': 'en',},
        {'code': 'en-us',},
        {'code': 'it',},
        {'code': 'nl',},
    'default': {
        'fallback': 'en',             # defaults to PARLER_DEFAULT_LANGUAGE_CODE
        'hide_untranslated': False,   # the default; let .active_translations() return fallbacks too.

Replace None with the SITE_ID when you run a multi-site project with the sites framework. Each SITE_ID can be added as additional entry in the dictionary.

Make sure your project is configured for multiple languages. It might be useful to limit the LANGUAGES setting. For example:

from django.utils.translation import gettext_lazy as _


    ('en', _("English")),
    ('en-us', _("US English")),
    ('it', _('Italian')),
    ('nl', _('Dutch')),
    ('fr', _('French')),
    ('es', _('Spanish')),

By default, the fallback language is the same as LANGUAGE_CODE. The fallback language can be changed in the settings:


Creating models

Using the TranslatedFields wrapper, model fields can be marked as translatable:

from django.db import models
from parler.models import TranslatableModel, TranslatedFields

class MyModel(TranslatableModel):
    translations = TranslatedFields(
        title = models.CharField(_("Title"), max_length=200)

    def __unicode__(self):
        return self.title

Accessing fields

Translatable fields can be used like regular fields:

>>> object = MyModel.objects.all()[0]
>>> object.get_current_language()
>>> object.title
u'cheese omelet'

>>> object.set_current_language('fr')       # Only switches
>>> object.title = "omelette du fromage"    # Translation is created on demand.

Internally, django-parler stores the translated fields in a separate model, with one row per language.

Filtering translations

To query translated fields, use the .translated() method:

MyObject.objects.translated(title='cheese omelet')

To access objects in both the current and possibly the fallback language, use:

MyObject.objects.active_translations(title='cheese omelet')

This returns objects in the languages which are considered \"active\", which are:

  • The current language
  • The fallback language when hide_untranslated=False in the PARLER_LANGUAGES setting.

Changing the language

The queryset can be instructed to return objects in a specific language:

>>> objects = MyModel.objects.language('fr').all()
>>> objects[0].title
u'omelette du fromage'

This only sets the language of the object. By default, the current Django language is used.

Use object.get_current_language() and object.set_current_language() to change the language on individual objects. There is a context manager to do this temporary:

from parler.utils.context import switch_language

with switch_language(model, 'fr'):
    print model.title

And a function to query just a specific field:

model.safe_translation_getter('title', language_code='fr')

Advanced Features

This package also includes:

  • Creating the TranslatedFieldsModel manually!
  • Form classes for inline support.
  • View classes for switching languages, creating/updating translatable objects.
  • Template tags for language switching-buttons.
  • ORM methods to handle the translated fields.
  • Admin inlines support.

See the documentation for more details.

Special notes

  • Using ModelAdmin.prepopulated_fields doesn\'t work, but you can use get_prepopulated_fields() as workaround.
  • Due to ORM restrictions queries for translated fields should be performed in a single .translated(..) or .active_translations(..) call.
  • The .active_translations(..) method typically needs to .distinct() call to avoid duplicate results of the same object.


  • The list code currently performs one query per object. This needs to be reduced.
  • Preferably, the TranslatedField proxy on the model should behave like a RelatedField, if that would nicely with the ORM too.
