example/views.py

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 (am) 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('am')
<FooItem: Lorem ipsum AM>
>>> 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
True

All available translations for foo:

>>> foo.available_translations.all()
[<FooItem: Lorem ipsum AM>, <FooItem: Lorem ipsum NL>]

All available translations for Armenian foo.

>>> armenian_foo.available_translations.all()
[<FooItem: Lorem ipsum>, <FooItem: Lorem ipsum NL>]
