Thank you so much for your incredibly thorough response, Emmanuel! That is
exactly the kind of insight I was hoping for.
Best,

Subject: Re: Runtime decision on language support
To achieve this, you can create a custom middleware that inherits from
`LocaleMiddleware`. In your custom middleware, you can override the
`process_request` method to check for the tenant's allowed languages and set
the request's language accordingly.
1. Create a new model field for the Tenant model that stores the allowed
languages as a list. This can be a JSON field or a ManyToMany field linked to a
Language model.
# models.py
from django.contrib.postgres.fields import ArrayField
from django.db import models
class Tenant(models.Model):
...
allowed_languages = ArrayField(models.CharField(max_length=10))
2. Create a custom middleware that inherits from
`django.middleware.locale.LocaleMiddleware`:
# custom_middleware.py
from django.middleware.locale import LocaleMiddleware
from django.utils import translation
class CustomLocaleMiddleware(LocaleMiddleware):
def process_request(self, request):
# Get the current tenant
current_tenant = request.tenant
# Get the user's preferred language from the request
language = translation.get_language_from_request(request,
check_path=True)
# Check if the preferred language is in the tenant's allowed_languages
list
if language not in current_tenant.allowed_languages:
# If not, set the default language for the tenant
language = current_tenant.default_language
# Activate the chosen language
translation.activate(language)
request.LANGUAGE_CODE = translation.get_language()
3. Replace `LocaleMiddleware` with your custom middleware in your `MIDDLEWARE`
settings:
# settings.py
MIDDLEWARE = [
...
# 'django.middleware.locale.LocaleMiddleware',
'your_app.custom_middleware.CustomLocaleMiddleware'.
Now, when a user requests a page, the custom middleware checks if the requested
language is in the tenant's `allowed_languages` list. If it is not, the
tenant's default language will be used. This ensures that the UI and the data
are shown in a consistent language.
