Question

我正在尝试使用django-modeltranslation翻译我的模型，而SlugField给我带来了很多麻烦。我已成功注册了要翻译的字段，您可以在db表描述中看到：

                                     Table "public.news_news"
    Column    |           Type           |                       Modifiers                        
--------------+--------------------------+--------------------------------------------------------
 id           | integer                  | not null default nextval('news_news_id_seq'::regclass)
 title        | character varying(255)   | not null
 title_en     | character varying(255)   | 
 title_nb     | character varying(255)   | 
 slug         | character varying(50)    | not null
 slug_en      | character varying(50)    | 
 slug_nb      | character varying(50)    |

但是当我尝试添加新的新闻项时，我收到以下错误：

Traceback: File "/home/roberto/.virtualenvs/ve_news/local/lib/python2.7/site-packages/django/core/handlers/base.py" in get_response

Exception Type: KeyError at /en/admin/news/news/add/ Exception Value: u"Key 'slug' not found in Form"

我的admin.py：

from cmsplugin_news.admin import NewsAdmin as OldNewsAdmin

class NewsAdmin(OldNewsAdmin, TranslationAdmin,):
    fields = ('title', 'slug')
    form = NewNewsForm

models.py：

class News(models.Model):
    title = models.CharField(_('Title'), max_length=255)
    slug = models.SlugField(
        _('Slug'), unique_for_date='pub_date',
    )

和forms.py:

class NewNewsForm(forms.ModelForm):
    class Meta:
        model = News
        fields = ('title', 'slug', )

同样，这是我的translation.py，其中我声明了应该由django-modeltranslation翻译的字段。我想无论如何错误不在这里，因为字段已在db：

中翻译

class NewsTranslationOptions(TranslationOptions):
    fields = ('title', 'slug', 'excerpt', 'content')

translator.register(News, NewsTranslationOptions)

请帮忙吗？我真的被卡住了！谢谢！

如何翻译SlugField？
