请看一下这个问题：

如何将 ModelForm 与 django-translated-fields 一起使用？

你有什么解决办法吗？

简而言之，我正在尝试将 Speedy Net 从 using 转换django-modeltranslation为django-translated-fields. 我定义了模型和表单，一切都用英语工作，但是用另一种语言（希伯来语）我有一个问题，表单字段是用英语而不是希伯来语（当前语言）定义的。我做错了什么，如何定义表格以使用当前语言？（模型中由 TranslatedField 定义的字段应仅在 SpeedyMatchProfileActivationForm 形式的当前语言中可见）。

我想澄清一下，所需的定义与上述不同。所需的定义是使用表单中的当前语言，而不是始终使用英语。当前语言不是英语时使用英语是一个错误。

你可以在这里看到代码：

树

表格.py

模型.py

现在的问题在于类SpeedyMatchProfileActivationForm（在forms.py中定义）。我认为这主要是因为类是在get_language()返回任何东西之前定义的。但是当类被定义时django-modeltranslation（例如在 branch staging中），它就起作用了。

顺便说一句，我想切换到的原因之一django-translated-fields是因为它在数据库中只定义了 2 个（语言数量）字段，并django-modeltranslation定义了 3 个字段 - 其中一个（没有任何语言的主要字段）在我看来不是完全有必要。看看： 删除迁移时的原始语言字段

class SpeedyMatchProfileActivationForm现在定义（带有django-translated-fields，链接）：

class SpeedyMatchProfileActivationForm(forms.ModelForm):
    validators = {
        'height': [speedy_match_accounts_validators.validate_height],
        'smoking_status': [speedy_match_accounts_validators.validate_smoking_status],
        'marital_status': [speedy_match_accounts_validators.validate_marital_status],
        to_attribute(name='profile_description'): [speedy_match_accounts_validators.validate_profile_description],
        to_attribute(name='city'): [speedy_match_accounts_validators.validate_city],
        to_attribute(name='children'): [speedy_match_accounts_validators.validate_children],
        to_attribute(name='more_children'): [speedy_match_accounts_validators.validate_more_children],
        to_attribute(name='match_description'): [speedy_match_accounts_validators.validate_match_description],
        'gender_to_match': [speedy_match_accounts_validators.validate_gender_to_match],
        'min_age_match': [speedy_match_accounts_validators.validate_min_age_match],
        'max_age_match': [speedy_match_accounts_validators.validate_max_age_match],
        'diet_match': [speedy_match_accounts_validators.validate_diet_match],
        'smoking_status_match': [speedy_match_accounts_validators.validate_smoking_status_match],
        'marital_status_match': [speedy_match_accounts_validators.validate_marital_status_match],
    }
    diet = forms.ChoiceField(choices=User.DIET_VALID_CHOICES, widget=forms.RadioSelect(), label=_('My diet'), validators=[speedy_match_accounts_validators.validate_diet])
    photo = forms.ImageField(required=False, widget=CustomPhotoWidget, label=_('Add profile picture'))

    class Meta:
        model = SpeedyMatchSiteProfile
        fields = ('photo', to_attribute(name='profile_description'), to_attribute(name='city'), 'height', to_attribute(name='children'), to_attribute(name='more_children'), 'diet', 'smoking_status', 'marital_status', 'gender_to_match', to_attribute(name='match_description'), 'min_age_match', 'max_age_match', 'diet_match', 'smoking_status_match', 'marital_status_match')
        widgets = {
            'smoking_status': forms.RadioSelect(),
            'marital_status': forms.RadioSelect(),
            to_attribute(name='profile_description'): forms.Textarea(attrs={'rows': 3, 'cols': 25}),
            to_attribute(name='city'): forms.TextInput(),
            to_attribute(name='children'): forms.TextInput(),
            to_attribute(name='more_children'): forms.TextInput(),
            to_attribute(name='match_description'): forms.Textarea(attrs={'rows': 3, 'cols': 25}),
            'diet_match': CustomJsonWidget(choices=User.DIET_VALID_CHOICES),
            'smoking_status_match': CustomJsonWidget(choices=SpeedyMatchSiteProfile.SMOKING_STATUS_VALID_CHOICES),
            'marital_status_match': CustomJsonWidget(choices=SpeedyMatchSiteProfile.MARITAL_STATUS_VALID_CHOICES),
        }

它是以前定义的（带有django-modeltranslation, link）：

class SpeedyMatchProfileActivationForm(TranslationModelForm):
    validators = {
        'height': [speedy_match_accounts_validators.validate_height],
        'min_age_match': [speedy_match_accounts_validators.validate_min_age_match],
        'max_age_match': [speedy_match_accounts_validators.validate_max_age_match],
        'smoking_status': [speedy_match_accounts_validators.validate_smoking_status],
        'city': [speedy_match_accounts_validators.validate_city],
        'marital_status': [speedy_match_accounts_validators.validate_marital_status],
        'children': [speedy_match_accounts_validators.validate_children],
        'more_children': [speedy_match_accounts_validators.validate_more_children],
        'profile_description': [speedy_match_accounts_validators.validate_profile_description],
        'match_description': [speedy_match_accounts_validators.validate_match_description],
        'gender_to_match': [speedy_match_accounts_validators.validate_gender_to_match],
        'diet_match': [speedy_match_accounts_validators.validate_diet_match],
        'smoking_status_match': [speedy_match_accounts_validators.validate_smoking_status_match],
        'marital_status_match': [speedy_match_accounts_validators.validate_marital_status_match],
    }
    diet = forms.ChoiceField(choices=User.DIET_VALID_CHOICES, widget=forms.RadioSelect(), label=_('My diet'), validators=[speedy_match_accounts_validators.validate_diet])
    photo = forms.ImageField(required=False, widget=CustomPhotoWidget, label=_('Add profile picture'))

    class Meta:
        model = SpeedyMatchSiteProfile
        fields = ('photo', 'profile_description', 'city', 'height', 'children', 'more_children', 'diet', 'smoking_status', 'marital_status', 'gender_to_match', 'match_description', 'min_age_match', 'max_age_match', 'diet_match', 'smoking_status_match', 'marital_status_match')
        widgets = {
            'profile_description': forms.Textarea(attrs={'rows': 3, 'cols': 25}),
            'children': forms.TextInput(),
            'more_children': forms.TextInput(),
            'smoking_status': forms.RadioSelect(),
            'marital_status': forms.RadioSelect(),
            'match_description': forms.Textarea(attrs={'rows': 3, 'cols': 25}),
            'diet_match': CustomJsonWidget(choices=User.DIET_VALID_CHOICES),
            'smoking_status_match': CustomJsonWidget(choices=SpeedyMatchSiteProfile.SMOKING_STATUS_VALID_CHOICES),
            'marital_status_match': CustomJsonWidget(choices=SpeedyMatchSiteProfile.MARITAL_STATUS_VALID_CHOICES),
        }

谢谢！

我找到了解决方案。这不是最佳解决方案，但它有效。我将所有语言的字段添加到表单中。我们不需要的字段已经在__init__方法中删除。

class SpeedyMatchProfileActivationForm(forms.ModelForm):
    validators = {
        'height': [speedy_match_accounts_validators.validate_height],
        'smoking_status': [speedy_match_accounts_validators.validate_smoking_status],
        'marital_status': [speedy_match_accounts_validators.validate_marital_status],
        **{to_attribute(name='profile_description', language_code=language_code): [speedy_match_accounts_validators.validate_profile_description] for language_code, language_name in django_settings.LANGUAGES},
        **{to_attribute(name='city', language_code=language_code): [speedy_match_accounts_validators.validate_city] for language_code, language_name in django_settings.LANGUAGES},
        **{to_attribute(name='children', language_code=language_code): [speedy_match_accounts_validators.validate_children] for language_code, language_name in django_settings.LANGUAGES},
        **{to_attribute(name='more_children', language_code=language_code): [speedy_match_accounts_validators.validate_more_children] for language_code, language_name in django_settings.LANGUAGES},
        **{to_attribute(name='match_description', language_code=language_code): [speedy_match_accounts_validators.validate_match_description] for language_code, language_name in django_settings.LANGUAGES},
        'gender_to_match': [speedy_match_accounts_validators.validate_gender_to_match],

        widgets = {
