密码存在验证的自定义错误消息

问题描述

这看起来应该很简单.注册新用户时，我想要空白用户名和密码的自定义错误.它适用于用户名:

It seems like this should be straightforward. When signing up new users, I want custom errors for blank user names and passwords. It worked fine for the user name:

validates :name, presence: { message: "Please enter a name." },

                      length: { maximum: 50,
                      message: "Please enter a name shorter than 50 characters"}

当该字段为空时，它会显示请输入名称".错误.

When the field is blank, it gives the "Please enter a name." error.

密码也一样:

 has_secure_password
     validates :password, presence: { message: "Please enter a password." },
                          length: { minimum: 8,
                             message: "Please choose a password with at least 8 \
                             characters."}

最小长度消息工作正常.但是，如果我使用空密码提交，则会收到默认的不能为空"消息.

The minimum length message works fine. But if I submit with an empty password, I get the default "can't be blank" message.

推荐答案

has_secure_password validations: false 起初有效，但在编辑用户配置文件页面时遇到问题.它假定用户可能没有输入密码.所以这取决于 has_secure_password 中的验证，上面的答案禁用了.

has_secure_password validations: false worked at first, but I had a problem when I made the edit user profile page. It assumes the user might not enter a password. So it depends on the validations in has_secure_password, which the answer above disables.

更好的方法是编辑 config/local/en.yml:

A better way is to edit config/local/en.yml:

en:
  activerecord:
    attributes:
      user:
        password: "Password"
    errors:
      models:
        user:
          attributes:
            password:
              blank: "Please enter a password."
