使用带有 django-translated-fields 的表单

Question

请看一下这个问题：

How do I use ModelForm with django-translated-fields?

你有什么解决办法吗？

简而言之，我正在尝试将 Speedy Net 从使用 django-modeltranslation 转换为 django-translated-fields。我定义了模型和表单，一切都用英语工作，但在另一种语言（希伯来语）中我遇到了一个问题，即表单字段是用英语而不是希伯来语（当前语言）定义的。我做错了什么以及如何定义表格以在当前语言中工作？（模型中由 TranslatedField 定义的字段应该仅在 SpeedyMatchProfileActivationForm 形式的当前语言中可见）。

我想澄清一下，我想要的定义不是上面那样。所需的定义是使用表格中的当前语言，而不是始终使用英语。当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：

tree

forms.py

models.py

现在的问题是 class SpeedyMatchProfileActivationForm（在 forms.py 中定义）。我认为这主要是因为 class 是在 get_language() returns 任何东西之前定义的。但是当 class 被定义为 django-modeltranslation 时（例如在分支 staging 中），它起作用了。

顺便说一句，我想切换到django-translated-fields的原因之一是因为它在数据库中只定义了2个（语言的数量）字段，而django-modeltranslation定义了3个字段-其中之一（没有任何语言的主要领域）在我看来根本没有必要。看一眼： Remove original language field on migrations

class SpeedyMatchProfileActivationForm 现在已定义（使用 django-translated-fields、link）：

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),
        }

之前定义过（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！

我找到了解决办法。这不是最佳解决方案，但它确实有效。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],

    }
    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:

        )
        widgets = {
            'smoking_status': forms.RadioSelect(),
            'marital_status': forms.RadioSelect(),
            **{to_attribute(name='profile_description', language_code=language_code): forms.Textarea(attrs={'rows': 3, 'cols': 25}) for language_code, language_name in django_settings.LANGUAGES},
