我试图将我的应用程序切换为使用多语言ng，不幸的是，网上的文档和常见问题解答很少。我希望有人能够说出我的练习是怎么回事，
以下是我的模型
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")
以下是我 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)
当我访问我的管理面板时，我可以看到模型、项目列表、添加新项目，但当我尝试编辑现有项目或删除一个项目时，我收到以下错误

不要使用 django-multilingual-ng，因为它不再受支持，会给你带来很多麻烦。django-multilingual-ng的作者开始了一个新的有前途的项目，名为django-nani。它应该是可靠的，并且与Django 1.3兼容。
至于我，这个问题没有出现在 Django 1.2.4 上，所以一旦你浏览了 Django 1.2.5 发行说明，你可能想回到那个版本。
我从最新版本安装，错误消失了：
$ pip install git+https://github.com/ojii/django-multilingual-ng.git
尽管使用此版本时错误已消失，但它仍然表示不受支持。我非常倾向于回滚到 Django 1.2.4，但我仍在努力解决这个问题。
如前所述，django-nani 项目很有前途，但它仍处于 alpha 阶段。截至今天的修订版，我找不到处理任何类型的模型关系的方法。他们将很快着手。
我遇到了同样的问题，从 1.2.4 升级到 1.2.7 中的新安全版本。Ng 已经在使用中，即使对它的支持已被放弃，也无法换出。就是我们生活的世界。我找不到任何关于force_having在 django 查询系统中的角色的文档。
很高兴他们正在开发一个新系统。如果有人对force_having有任何了解，将不胜感激。
