Question

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

使用rails 3.1 ActiveModel :: SecurePassword

我结束了红灯......

user.rb

class User < ActiveRecord::Base
  has_secure_password
  validates :password, :presence => { :on => :create }
end

factory.rb

Factory.define :user do |f|
  f.email "foo@bar.com"
  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 => 'frank@gmail.com', :password => 'secret')
    User.authenticate('frank@gmail.com', 'secret').should == user
  end
end

我得到了红灯......

 Failure/Error: user = Factory(:user, :email => 'frank@gmail.com', :password => 'secret')
 NoMethodError:
   undefined method `password_digest=' for #<User:0xb383460>

我认为这是rake db：migrate问题，我查看了rails c，但很明显定义了password_digest。

ruby-1.9.2-p180 :007 > a = User.new
 => #<User id: nil, email: nil, password_digest: nil, is_admin: nil, created_at: nil, updated_at: nil> 
ruby-1.9.2-p180 :008 > a.password_digest = 3
 => 3

Answer 1

我遇到了同样的问题，并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 => 'frank@gmail.com', :password => 'secret')
    User.find_by_email('frank@gmail.com').try(:authenticate, 'secret').should == user
  end
end

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