如何在Django的modelform小部件中添加自定义错误消息 [英] how to add custom error messages in modelform widgets in django

问题描述

这些是模型形式的字段类Meta:

these are fields of the model form class Meta:

    model = Employee
    exclude = ('user', 'created_by', 'is_deleted', 'created')

这些是小部件

    widgets = {
        'first_name': forms.TextInput(attrs={'placeholder': _('First name')}),
        'last_name': forms.TextInput(attrs={'placeholder': _('Last name')}),
        'house_name': forms.TextInput(attrs={'placeholder': _('House name / flat No')}),
        'street_name': forms.TextInput(attrs={'placeholder': _('Street Name / No')}),
        'locality_name': forms.TextInput(attrs={'placeholder': _('Locality Name / No')}),
        'pin_code': forms.TextInput(attrs={'placeholder': _('Zip Code')}),
    }

推荐答案

错误消息未放置在小部件内

Error messages are not placed inside widgets

class MyForm(forms.ModelForm):

   class Meta:
       model=Employee
       exclude = ('user', 'created_by', 'is_deleted', 'created')
       error_messages = {
        'first_name': {
            'max_length': _("This writer's name is too long."),
           },
       }
