Re: Generate different querysets depending of the website language

Hello.

I have been doing some tests, here are my results :

The Django default language (fallback) is in Spanish in all case

No IgnoreHTTPLanguageMiddleware

Browser having English has priority

URL specified language in Spanish /es/

-> Translated blocks in Spanish

-> Language related DB queries in English

URL specified language in English /en/

-> Translated blocks in English

-> Language related DB queries in English

No IgnoreHTTPLanguageMiddleware

Browser having Spanish has priority

URL specified language in Spanish /es/

-> Translated blocks in Spanish

-> Language related DB queries in Spanish

URL specified language in English /en/

-> Translated blocks in English

-> Language related DB queries in Spanish

IgnoreHTTPLanguageMiddleware enabled

Browser having Spanish has priority

URL specified language in Spanish /es/

-> Translated blocks in Spanish

-> Language related DB queries in Spanish

URL specified language in English /en/

-> Translated blocks in English

-> Language related DB queries in Spanish

IgnoreHTTPLanguageMiddleware enabled

Browser having English has priority

URL specified language in Spanish /es/

-> Translated blocks in Spanish

-> Language related DB queries in Spanish

URL specified language in English /en/

-> Translated blocks in English

-> Language related DB queries in Spanish

Basically, it looks like the block translations always use the language specified in the URL, where my queries always use the language specified in the HTTP request header... Is there something wrong with get_language() that could cause this ? Is there a better way ?

So I suppose when I "silence" the HTTP request header language it fallbacks to the default "Spanish" language.

Hmm, after some search, adding check_path=True to get_language_from_request fix this :)

Thank you.

Hello again,

In that case, I would double-check the middleware process and settings in your project.

One reason could be your are placing LocaleMiddleware after your ForceDefaultLanguage,

so https://github.com/django/django/blob/master/django/middleware/locale.py#L26

is setting the default language.

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
