[英]Custom error messages not working in Django ModelForm
I have a ModelForm and I want to customize some of the error messages for required fields. 我有一个ModelForm,我想为必填字段自定义一些错误消息。 Some of the customized error messages work, but some don't.
一些自定义的错误消息有效,但有些无效。 Here is my code:
这是我的代码:
error_messages = {
'photo': {
'required': _("A profile picture is required."),
},
'height': {
'required': _("Your height is required."),
},
'diet': {
'required': _("Your diet is required."), # ~~~~ TODO: not working.
},
'smoking_status': {
'required': _("Your smoking status is required."), # ~~~~ TODO: not working.
},
'relationship_status': {
'required': _("Your relationship status is required."), # ~~~~ TODO: not working.
},
**{to_attribute(name='profile_description', language_code=language_code): {
'required': _("Please write a few words about yourself."),
} for language_code, language_name in django_settings.LANGUAGES},
**{to_attribute(name='city', language_code=language_code): {
'required': _("Please write where you live."), # ~~~~ TODO: not working.
} for language_code, language_name in django_settings.LANGUAGES},
**{to_attribute(name='children', language_code=language_code): {
'required': _("Do you have children? How many?"),
} for language_code, language_name in django_settings.LANGUAGES},
**{to_attribute(name='more_children', language_code=language_code): {
'required': _("Do you want (more) children?"),
} for language_code, language_name in django_settings.LANGUAGES},
**{to_attribute(name='match_description', language_code=language_code): {
'required': _("Who is your ideal partner?"),
} for language_code, language_name in django_settings.LANGUAGES},
'gender_to_match': {
'required': _("Gender to match is required."), # ~~~~ TODO: not working.
},
'min_age_to_match': {
'required': _("Minimal age to match is required."),
},
'max_age_to_match': {
'required': _("Maximal age to match is required."),
},
'diet_match': {
'required': _("Diet match is required."),
},
'smoking_status_match': {
'required': _("Smoking status match is required."),
},
'relationship_status_match': {
'required': _("Relationship status match is required."),
},
}

I marked the custom error messages which are not working with # ~~~~ TODO: not working.
我标记了与
# ~~~~ TODO: not working.
兼容的自定义错误消息# ~~~~ TODO: not working.
. 。 The others are working.
其他人在工作。
Any suggestions? 有什么建议么?
OK, I found out that I have to define these error messages when I declare the fields or the widgets: 好的,我发现在声明字段或窗口小部件时必须定义以下错误消息:
photo = forms.ImageField(required=False, widget=CustomPhotoWidget, label=_('Add profile picture'), error_messages={'required': _("A profile picture is required.")})
diet = forms.ChoiceField(widget=forms.RadioSelect(), label=_('My diet'), error_messages={'required': _("Your diet is required.")})
smoking_status = forms.ChoiceField(widget=forms.RadioSelect(), label=_('My smoking status'), error_messages={'required': _("Your smoking status is required.")})
relationship_status = forms.ChoiceField(widget=forms.RadioSelect(), label=_('My relationship status'), error_messages={'required': _("Your relationship status is required.")})
gender_to_match = forms.MultipleChoiceField(choices=User.GENDER_CHOICES, widget=forms.CheckboxSelectMultiple, error_messages={'required': _("Gender to match is required.")})
# ~~~~ TODO: define all the languages and not just hard-code languages like below.
_city = forms.CharField(label=_('City or locality'), max_length=120, error_messages={'required': _("Please write where you live.")})
city_en = _city
city_he = _city

The error message can also be customized in the __init__
method: 错误消息也可以在
__init__
方法中自定义:
if (to_attribute(name='profile_description') in self.fields):
self.fields[to_attribute(name='profile_description')].error_messages = {'required': pgettext_lazy(context=self.instance.user.get_gender(), message="Please write a few words about yourself.")}
if (to_attribute(name='city') in self.fields):
self.fields[to_attribute(name='city')].error_messages = {'required': pgettext_lazy(context=self.instance.user.get_gender(), message="Please write where you live.")}
if (to_attribute(name='children') in self.fields):
self.fields[to_attribute(name='children')].label = pgettext_lazy(context=self.instance.user.get_gender(), message='Do you have children? How many?')
self.fields[to_attribute(name='children')].error_messages = {'required': pgettext_lazy(context=self.instance.user.get_gender(), message="Do you have children? How many?")}
if (to_attribute(name='more_children') in self.fields):
self.fields[to_attribute(name='more_children')].label = pgettext_lazy(context=self.instance.user.get_gender(), message='Do you want (more) children?')
self.fields[to_attribute(name='more_children')].error_messages = {'required': pgettext_lazy(context=self.instance.user.get_gender(), message="Do you want (more) children?")}
if (to_attribute(name='match_description') in self.fields):
self.fields[to_attribute(name='match_description')].label = pgettext_lazy(context=self.instance.get_match_gender(), message='My ideal match')
self.fields[to_attribute(name='match_description')].error_messages = {'required': pgettext_lazy(context=self.instance.get_match_gender(), message="Who is your ideal partner?")}
