python之是否可以在管理员之外使用 django-modeltranslation

我使用 django-modeltranslation我的 Django 1.11 项目中的应用程序。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，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') 

表单.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:

请您参考如下方法:

我也遇到了同样的错误，遇到了这个问题。但后来我找到了答案。

您正在使用 TranslationModelForm 扩展您的表单，而必须使用 Django 的 ModelForm 来扩展它。因为如docs中所述TranslationModelForm 去除了所有翻译字段。

这里需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，您都必须在 fields 中手动添加它，例如，title_en， title_de, title_ru 等

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