Question

我在Django中编写了这个函数来覆盖＆＃39;标签后缀和表单字段错误消息。在同一个函数中，lebel后缀正在工作（冒号被删除）但错误消息没有被自定义的替换。这是带有函数的表单类：

class User_accountModelForm(forms.ModelForm):

    # to remove colons from the labels:
    def __init__(self, *args, **kwargs):
        kwargs.setdefault('label_suffix', '')
        super(User_accountModelForm, self).__init__(*args, **kwargs)

        # changing error messages:
        for field in self.fields.values():
        field.error_messages = {'required':'The field {fieldname} is required'.format(fieldname=field.label)}



    class Meta:
        model = User_account
        fields = ['first_name', 'other fields']

感谢任何帮助或线索

要覆盖表单错误消息，请将其添加到表单Meta;另见ModelForm docs：

class User_accountModelForm(ModelForm):
    class Meta:
        model = User_account
        fields = ['first_name', 'other fields']
        error_messages = {
            'first_name': {
                # for example:
                'max_length': _("This writer's name is too long."),
            },
        }

自定义错误消息＆＃39;请填写此表单＆＃39;在Django
