我在我的 Django 1.11 项目中使用django-modeltranslation应用程序。我成功安装了应用程序并进行了设置，还按照文档中的建议注册了翻译模型。

问题：是否可以在管理员之外使用此应用程序？如果可能的话我需要做什么？

翻译.py：

class ArticleTranslationOptions(TranslationOptions):
    fields = ('title', 'body',)

translator.register(Article, ArticleTranslationOptions)

设置.py：

LANGUAGE_CODE = 'ru'

LANGUAGES = (
    ('ru', _('Russian')),
    ('en', _('English')),
    ('de', _('German')),
)

MODELTRANSLATION_LANGUAGES = ('en', 'de')

表格.py：

from modeltranslation.forms import TranslationModelForm

class ArticleForm(TranslationModelForm):
    """
        Form based on "Article" model.
    """

    class Meta:
        model = Article
        fields = ('title', 'title_en', 'title_de', 'body', 'body_en', 'body_de',)

    def __init__(self, *args, **kwargs):
        super(ArticleForm, self).__init__(*args, **kwargs)
        self.fields['title'].widget.attrs = {
            'class': 'form-control',
            'id': 'title',
        }
        self.fields['title_en'].widget.attrs = {
            'class': 'form-control',
            'id': 'title_en',
        }
        self.fields['title_de'].widget.attrs = {
            'class': 'form-control',
            'id': 'title_de',
        }
        self.fields['body'].widget.attrs = {
            'class': 'form-control',
            'id': 'opt_head',
        }
        self.fields['body_en'].widget.attrs = {
            'class': 'form-control',
            'id': 'body_en',
        }
        self.fields['body_de'].widget.attrs = {
            'class': 'form-control',
            'id': 'body_de',
        }

错误：

我也遇到了同样的错误并遇到了这个问题。但后来我找到了答案。

您正在扩展您的表单，TranslationModelForm而您必须使用 Django 的ModelForm. 因为正如文档中提到的那样，TranslationModelForm它会删除所有翻译字段。

这里要注意的一件重要事情是，无论您想在表单中显示哪个翻译字段，都必须手动添加fields，例如title_en，、title_de等title_ru。

from django.forms import ModelForm
class ArticleForm(ModelForm):
    class Meta:
        model = Article
        fields = ('title', 'title_en', 'title_de', 'body', 'body_en', 'body_de',)
