Simple implementation of multi-lingual models for Django. Django-admin integration works out of the box.

Support discontinued. There are many better alternatives available.


  • Django 1.5, 1.6, 1.7
  • Python 2.7, 3.4, 3.5, 3.6


Note, that Django 1.5 is required. Earlier versions are not supported.

  1. Installation

Latest stable version on PyPI:

pip install django-slim

Latest stable version on BitBucket:

pip install

Latest stable version on GitHub:

pip install
  1. Add slim to INSTALLED_APPS of you settings module.

Usage and examples

An extensive example project is available.

Screen shots are present in documentation on PythonHosted.


In order to be able to quickly evaluate the django-slim, a demo app (with a quick installer) has been created (Debian only). Follow the instructions below for having the demo running within a minute.

Grab the latest


Create a new- or switch to existing- virtual environment, assign execute rights to the installer and run the

chmod +x


Go to the front/back -end and test the app.

- Front-end URL:
- Admin URL:
- Admin username: admin
- Password: test

Let's now step-by-step review our imaginary example app.

Add slim to installed apps.

    # ...
    # ...

Add languages.

    ('en', gettext("English")),  # Main language!
    ('hy', gettext("Armenian")),
    ('nl', gettext("Dutch")),
    ('ru', gettext("Russian")),


from django.db import models

from slim import LanguageField, Slim

class FooItem(models.Model, Slim):

    title = models.CharField(_("Title"), max_length=100)
    slug = models.SlugField(unique=True, verbose_name=_("Slug"))
    body = models.TextField(_("Body"))
    language = LanguageField()


from django.contrib import admin

from slim.admin import SlimAdmin

class FooItemAdmin(SlimAdmin):

    list_display = ('title',)
    fieldsets = (
        (None, {
            'fields': ('title', 'slug', 'body')
    ), FooItemAdmin)


We assume that language code is kept in the request object (django-localeurl behaviour, which you're advised to use).

from slim import get_language_from_request

from example.models import FooItem

def browse(request, template_name='foo/browse.html'):
    language = get_language_from_request(request)
    queryset = FooItem._default_manager.filter(language=language)

    # The rest of the code

More on ORM filtering

from example.models import FooItem
foo = FooItem._default_manager.all()[0]
<FooItem: Lorem ipsum>

Let's assume, we have such record and it has been translated to Armenian (hy) and Dutch (nl). Original translation is named Lorem ipsum. Other translations have the language code appended to the title.

armenian_foo = foo.get_translation_for('hy')
<FooItem: Lorem ipsum HY>
dutch_foo = foo.get_translation_for('nl')
<FooItem: Lorem ipsum NL>

If we have a translated object, we can always get the main translation.

armenian_foo.original_translation == foo

All available translations for foo:

[<FooItem: Lorem ipsum HY>, <FooItem: Lorem ipsum NL>]

All available translations for Armenian foo.

[<FooItem: Lorem ipsum>, <FooItem: Lorem ipsum NL>]

See example directory for a working example.

django-localeurl integration

Note, that django-localeurl usage is deprecated. We're moving to nowadays approaches. This version (0.8) is the last version to support django-localeurl.


django-localeurl integration is fully supported for Python 2.6.* and 2.7.* and installs automatically when installing django-slim. If you are using Python 3, install a forked version of django-localeurl (since official version does not yet have support for Python 3).

Forked version from BitBucket:

$ pip install -e hg+


Use slim.models.decorators.auto_prepend_language decorator in order to have it working.

Example (have in mind our FooItem model.

from django.core.urlresolvers import reverse

from slim.models.decorators import auto_prepend_language

class FooItem(models.Model):

# Some other code; have in mind previous pieces. @auto_prepend_language def get_absolute_url(self):

kwargs = {'slug': self.slug} return reverse('foo.detail', kwargs=kwargs)

Do not forget to add the LocaleURLMiddleware to the MIDDLEWARE_CLASSES (as first).

'localeurl.middleware.LocaleURLMiddleware', # The rest...


Also, add localeurl to INSTALLED_APPS.

# Some apps... 'localeurl', # Some more apps...
