🎭 Use Modeltranslation

Camomilla comes with django-modeltranslation installed and configured. Modeltranslation is a django app that allows you to translate your models fields.

To use it, you need to add the modeltranslation app to your INSTALLED_APPS setting:

# <project_name>/settings.py

INSTALLED_APPS = [
    ...
    "modeltranslation",
    ...
]

🪡 Register your models

To translate a model, you need to register in the modeltranslation registry. To register a model, you need to create a translation.py file in your django app folder and register your models there.

Let's see an example:

# <project_name>/<app_name>/translation.py

from modeltranslation.translator import translator, TranslationOptions
from .models import MyModel

class MyModelTranslationOptions(TranslationOptions):
    fields = ("title", "description")

translator.register(MyModel, MyModelTranslationOptions)

In this example we registered the MyModel model and we specified that we want to translate the title and description fields.

TranslationOptions fields can be inherited from other TranslationOptions, so you can create a base TranslationOptions class and inherit from it in your models TranslationOptions.

For models that inherit from camomilla AbstractPage, should use the AbstractPageTranslationOptions class, to inherit all needed fields to translate.

# <project_name>/<app_name>/translation.py

from modeltranslation.translator import translator, TranslationOptions
from camomilla.translation import AbstractPageTranslationOptions
from .models import MyModel

class MyModelTranslationOptions(AbstractPageTranslationOptions):
    fields = ("title", "description")

translator.register(MyModel, MyModelTranslationOptions)

🚨 Caveats with Rest Framework

If you are using Django Rest Framework you should always declare get_queryset in your viewsets, otherwise the statically declared queryset will not provide results in the requested language.

# <project_name>/<app_name>/views.py

from rest_framework import viewsets

class MyModelViewSet(viewsets.ModelViewSet):
    queryset = MyModel.objects.all() # this will not work

    def get_queryset(self):
        return MyModel.objects.all()
