Django正则表达式验证器消息无效 [英] Django regex validator message has no effect

问题描述

我试图得到它，以便验证器告诉你用户名必须是字母数字。这是我的代码到目前为止。我已经确认它在正确的时间验证。唯一的问题是，无论我尝试什么，RegexValidator仍然会抓住默认错误（输入有效值）。

I am trying to get it so that the validator tells you "username must be alphanumeric". This is my code so far. I have confirmed that it validates at the correct time. The only problem is that no matter what I try, The RegexValidator still chucks the default error ("enter a valid value").

这是我的代码。我还尝试了没有'message ='在前面，它仍然说输入有效的值，而不是用户名必须是字母数字

This is my code. I also tried it without the 'message=' in front, and it still said "enter a valid value", instead of "username must be alphanumeric"

user = CharField(
    max_length=30,required=True,
    validators=[
        RegexValidator('^[a-zA-Z0-9]*$',
            message='Username must be Alphanumeric'
        ),
    ]
)

推荐答案

添加错误代码如何：

user = CharField(
    max_length=30,
    required=True,
    validators=[
        RegexValidator(
            regex='^[a-zA-Z0-9]*$',
            message='Username must be Alphanumeric',
            code='invalid_username'
        ),
    ]
)
