django-hvad Sample Code

admins.py

from django.contrib import admin
import models

from models import Portal

from hvad.admin import TranslatableAdmin, InlineModelForm

class PortalAdmin(TranslatableAdmin):
    # Don't use this:
    # fields = ('title', 'description', )

    # !!! Here is the magic !!!
    def get_fieldsets(self, request, obj=None):
        return (
            ("General", {
                "fields": (
                    "title",
                ),
            }),
            ("Localizables", {
                "fields": (
                    "description",
                    "details",
                )
            })
        )

admin.site.register(models.Portal, PortalAdmin)

Django Multilingual Model.md

I tried the first 2 items from Django Packages. And I found that django-hvad is better for me.

models.py

from django.db import models

from hvad.models import TranslatableModel, TranslatedFields

class Portal(TranslatableModel):
    title = models.CharField(max_length = 100, blank=True)
    
    translations = TranslatedFields(
        description = models.TextField(blank=True),
        details = models.CharField(max_length=255),
    )
    
    def __unicode__(self):
        return self.title
