Я пытаюсь переключить свое приложение на использование многоязычности, но, к сожалению, в Интернете очень мало документации и часто задаваемых вопросов.Я надеюсь, что кто-то сможет рассказать, что происходит с моей практикой,
моя модель
class Main(models.Model):
""" Main Class for all categories """
slug = models.SlugField()
is_active = models.BooleanField(default=True)
site = models.ForeignKey(Site)
parent = models.ForeignKey('self', blank=True, null=True)
class Translation(TranslationModel):
title = models.CharField(max_length=100)
label = models.CharField(max_length=100, blank=True, null=True)
description = models.TextField(blank=True, null=True)
disclaimer = models.TextField(blank=True, null=True)
class Meta:
unique_together = (("slug", "parent"))
def __unicode__(self):
return self.title if self.title is not None else _("No translation")
, а моя admin.py
class MainAdmin(MultilingualModelAdmin):
''' Multilingual interface for Main category '''
class ListAdmin(MultilingualModelAdmin):
''' Multilingual interface for Main category '''
admin.site.register(Main, MainAdmin)
admin.site.register(List, ListAdmin)
Когда я получаю доступ к своей панели администратора, я могу видеть модель, список элементов, добавлять новые элементы, но когда я пытаюсь изменить существующий элемент или удалить его, я получаю следующее сообщение об ошибке
