Django Parler shows translated object one time per translation on the admin list

[temperatio]

I'm using Django 4.1 and django-parler 2.3

Parler related config in settings.py

LANGUAGES = [
    ('en', _('English')),
    ('es', _('Spanish')),
    ('fr', _('French')),
    ('it', _('Italian')),
    ('de', _('German')),
    ('pt', _('Portuguese')),
    ('nl', _('Dutch')),
    ('pl', _('Polish')),
]

PARLER_LANGUAGES = {
    None: (
        {'code': 'en', },
        {'code': 'es', },
        {'code': 'fr', },
        {'code': 'it', },
        {'code': 'de', },
        {'code': 'pt', },
        {'code': 'nl', },
        {'code': 'pl', },
    ),
    'default': {
        'fallback': 'en',  # defaults to PARLER_DEFAULT_LANGUAGE_CODE
        'hide_untranslated': False,  # the default; let .active_translations() return fallbacks too.
    }
}

I created a model using TranslatableModel and TranslatableAdmin. Then I created an object and filled the translatable fields of the same object for every language. When I get to the model list page, I see oneobjects in the list for every translated lenguage. (As you can see on the screenshot below)

It's a bug or I'm doing something wrong.

César.

Is this project abandoned?

Hi @temperatio,
I've found myself with the same problem!

As a workaround, despite it does not solve the problem but mitigates it a bit, I've added a list filter to show the records translated to the selected language (and they appear only once).

This is the code of the language filter:

from django.conf import settings
from django.contrib import admin
from parler.admin import TranslatableAdmin
from parler.managers import TranslatableQuerySet

class LanguageListFilter(admin.SimpleListFilter):
    title = _("language")
    parameter_name = "language"

    def lookups(self, request, model_admin):
        return settings.LANGUAGES

    def queryset(self, request, queryset):
        if not self.value():
            return queryset
        if not isinstance(queryset, TranslatableQuerySet):
            return queryset
        return queryset.translated(self.value())

class MyModelAdmin(TranslatableAdmin):
    model = MyModel
    list_filter = (LanguageListFilter, )

@temperatio: are you ordering by a translated field? I've been digging more about this problem, and I've found that I had duplicates if I add order_by("translations__name") (for example) to the queryset.

@bielfrontera I have search_fields = ('translations__name')
