ruby-on-rails – 模型上的rspec和undefined方法

我有一个具有forgot_password值的用户模型,该值只是一个将通过电子邮件发送出去的哈希值.

这似乎有效

ruby-1.9.2-p290 :001 > u=User.find(1)
...
ruby-1.9.2-p290 :002 > u.forgot_password
 => "1280aceaf23f185a2d09a57b5534e7e3"

但是我收到以下错误：

1) PasswordResets emails user when requesting password reset
   Failure/Error: click_button "jt"
   NoMethodError:
     undefined method `forgot_password=' for #<User:0x007ff916b03da0>
   # /Users/jt/rails-1/app/controllers/users_controller.rb:61:in `forgot_password_confirmation'
   # (eval):2:in `click_button'

这是规格：

需要’spec_helper’

describe "PasswordResets" do
  it "emails user when requesting password reset" do
    user=Factory(:user)
    visit log_in_path
    click_link "password"
    fill_in "email",:with => user.email
    click_button "jt"
  end
end

NoMethodError告诉我什么？看起来好像来自rails c,forget_password值存在.我错过了什么？

谢谢
