ActiveModel :: SecurePassword未定义方法`password_digest =’

我尝试按照http://bcardarella.com/post/4668842452/exploring-rails-3-1-activemodel-securepassword使用rails 3.1 ActiveModel :: SecurePassword

我最后得到了红灯……

user.rb

class User  { :on => :create } end 

factory.rb

 Factory.define :user do |f| f.email "[e-mail]" f.password "foobar" f.password_confirmation { |u| u.password } end 

spec_user.rb

 describe User do it "should authenticate with matching username and password" do user = Factory(:user, :email => '[e-mail]', :password => 'secret') User.authenticate('[e-mail]', 'secret').should == user end end 

我得到了红灯……

  Failure/Error: user = Factory(:user, :email => '[e-mail]', :password => 'secret') NoMethodError: undefined method `password_digest=' for # 

我认为这是rake db：migrate问题，我查看了rails c，但显然定义了password_digest。

 ruby-1.9.2-p180 :007 > a = User.new => # ruby-1.9.2-p180 :008 > a.password_digest = 3 => 3

我遇到了同样的问题，在以下评论中找到了一个（我认为是）更好的解决方案：

基本上，您需要通过迁移向您的模型添加password_digest字段。 在此之前，它将添加一个password_digest =方法，但它不会被保存，并且该方法不会出现在工厂等中

Answer 2

解决了

 describe User do it "should authenticate with matching username and password" do user = Factory(:user, :email => '[e-mail]', :password => 'secret') User.find_by_email('[e-mail]').try(:authenticate, 'secret').should == user end end
