Question

你好我是ruby on rails的新手我在验证旧密码时遇到问题。如果我要进入编辑帐户页面，如果我保存它，旧密码的验证显示即使编辑帐户页面和更改密码页面是不同的页面，但它们共享一个模型。请帮帮我。

这是我的模特：

validates_presence_of :firstname, :message => 'First Name is required'
  validates_format_of :firstname, :with => /\A[a-zA-Z]+([a-zA-Z]|\d)*\Z/, :message => 'First name must not contain special characters'
  validates_presence_of :lastname, :message => 'Last Name is required'
  validates_format_of :lastname, :with => /\A[a-zA-Z]+([a-zA-Z]|\d)*\Z/, :message => 'Lastname name must not contain special characters'
  validates_presence_of :email, :message => 'Email Address is required'
  validates_uniqueness_of :email, :message => 'Email address is already taken, please select a new one'
  validates_format_of :email, :with => /^([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})$/i, :message => "Please enter a valid email address"
  validates_presence_of :username, :message => 'Username is required'
  validates_uniqueness_of :username, :message => 'Username is already taken, please select a new one'
  validates_length_of :username, :within => 3..15, :message => "Username must be at least 3 - 15 characters in length", :on => :create


  validates_presence_of :password_old, :on => :update, :message => "Old password is required"

如果您需要更多信息，请提前评论。

所以你说它在更新帐户信息时不应该检查密码。如果用户在更改密码字段中提供了新密码，您可以编写条件验证来检查old_password。

validates_presence_of :password_old, :on => :update, :unless => :current_password.nil?,:message => "Old password is required"
