Re: Generate different querysets depending of the website language

Hello,

If you are able to change the schema I would suggest you to use modeltranslation [https://github.com/deschler/django-modeltranslation],

also the source code of that app can help you in order to take an specific approach to your project.

About the URL's, if you use i18urls, it has priority over the http headers [https://docs.djangoproject.com/en/1.9/topics/i18n/translation/#module-django.conf.urls.i18n] (Not confirmed, but was true last time I checked it)

Hope it helps.

Hello,

I have an issue, I am creating a website that will be available in many languages, sharing the same database.

Most models have a "language" attribute that is the 2 letters from the language code (en, es, fr, etc.).

I am trying to find a way to show the correct content per language.

I tried many things, creating a custom manager :

from django.utils.translation import get_language, get_language_info

from django.db import models

class PerLanguageManager(models.Manager):

    def get_queryset(self):

        if get_language():

            return super(PerLanguageManager, self).get_queryset().filter(

                language=get_language_info(get_language())['code'])

        else:

            return super(PerLanguageManager, self).get_queryset()

Or overriding get_queryset using another method : (The language is always present in the url as /en/ or /es/) 

class RecipeIndexView(generic.ListView):

    paginate_by = 10

    def get_queryset(self):

        return Recipe.objects.filter(language=get_language_from_request(self.request, check_path=False))

But nothing work, I always get the default configured language (even if with the debug toolbar tell me the site is in another language, and all the translations are correctly done in the language specified in the URL, I always get the default language from the queries...)

I'm using a specific middleware to ignore the language specified in the browser to only use the language specified in the URL :

class ForceDefaultLanguageMiddleware(object):

    """

    Ignore Accept-Language HTTP headers

    This will force the I18N machinery to always choose settings.LANGUAGE_CODE

    as the default initial language, unless another one is set via sessions or cookies

    Should be installed *before* any middleware that checks request.META['HTTP_ACCEPT_LANGUAGE'],

    namely django.middleware.locale.LocaleMiddleware

    """

    def process_request(self, request):

        if 'HTTP_ACCEPT_LANGUAGE' in request.META:

            del request.META['HTTP_ACCEPT_LANGUAGE']

Any idea of how to make this work ? What is the good way to do this ?

Thank you.

Mathieu
