ruby-on-rails - 密码存在验证的自定义错误消息

Question

看起来这应该是直截了当的。注册新用户时，我想要针对空白用户名和密码的自定义错误。它适用于用户名:

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

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

当该字段为空白时，它给出“请输入名称”。错误。

密码也是一样:

 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，我会收到默认的“不能为空”消息。

Answer 1

has_secure_password自动为您添加一些验证:

Password must be present on creation

Password length should be less than or equal to 72 characters

Confirmation of password (using a password_confirmation attribute)

为防止这种情况发生，请声明:

has_secure_password validations: false

然后您可以添加自己的。
