在django 1.3上使用django-multilingual ng编辑时，管理页面出现错误

Question

我试图将我的应用程序切换到使用多语言ng，但不幸的是，在线文档和常见问题解答很少。我希望有人能告诉我我的诊所是怎么回事，

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")

下面是我的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项目时，我得到以下错误

Answer 1

不要使用django-multilingual ng，因为它不再被支持，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。

对我来说，这个问题在Django 1.2.4上没有表现出来，所以一旦你通过Django 1.2.5 release notes，你可能会想要回到那个版本。

Answer 2

我安装了最新的版本，错误消失了：

$ pip install git+https://github.com/ojii/django-multilingual-ng.git

虽然这个版本的错误消失了，但它仍然显示它不受支持。我非常倾向于回滚到Django 1.2.4，但我仍然在努力弄清楚这一点。

正如前面提到的，django-nani项目前景看好，但它仍处于alpha阶段。截至今天的修订，我找不到一种方法来处理任何类型的模型关系。他们will be working on it soon。

Answer 3

我也遇到了同样的问题，从1.2.4升级到1.2.7的新安全版本。Ng已经在使用中，不能被替换掉，即使对它的支持已经被删除。就是我们生活的世界。我找不到任何关于force_having在django查询系统中角色的文档。

很高兴他们正在开发一种新的系统。如果有人对force_having有所了解，我们将不胜感激。
