我正在尝试设置我的程序,以便仅在密码更改时验证密码(这样用户可以编辑其他信息而无需输入密码).
我目前收到错误消息
NoMethodError in UsersController#create,undefined method `password_changed?' for #<User:0x00000100d1d7a0>
当我尝试登录时
这是我在user.rb中的验证码:
validates :name,:presence => true,:length => { :maximum => 50 } validates :email,:presence => true,:format => { :with => email_regex },:uniqueness => { :case_sensitive => false } validates :password,:presence =>true,:confirmation => true,:length => { :within => 6..40 },:if=>:password_changed?
这是我在users_controller.rb中的create方法:
def create @user = User.new(params[:user]) if @user.save sign_in @user flash[:success] = "Welcome to the Sample App!" redirect_to @user else @title = "Sign up" render 'new' end end
谢谢!
解决方法
用…来代替:
:if => lambda {|user| user.password_changed? }
我会做两种不同的验证:
validates :password,:on => :create validates :password,:on => :update,:unless => lambda{ |user| user.password.blank? }
