从控制台设计的current_user方法

Question

rails 3.2.18
devise
pry-rails gem (which installs pry)
pry-doc gem

我启动了rails控制台：

rails c

然后我登录了：

然后我登录了：

[13] pry(main)> ApplicationController.allow_forgery_protection = false
=> false
[14] pry(main)> app.post('/sign_in', {"user"=>{"login"=>"p3.rails.production@gmail.com", "password"=>"Vw#98052"}})
=> 302

302表示我已成功登录，这意味着我可以致电：

[15] pry(main)> app.controller.current_user

但我收到以下回复：

NoMethodError: undefined method `current_user' for #<Devise::FailureApp:0x000000094e33c0>
from (pry):13:in `__pry__'

[16] pry(main)> app.session

给我：

=> {"flash"=>
  #<ActionDispatch::Flash::FlashHash:0x00000009509598
   @closed=false,
   @flashes={:alert=>"You need to sign in or sign up before continuing."},
   @now=nil,
   @used=#<Set: {}>>}
