Problems with Warden:Manager after_authentication callsbacks
原标题:Problems with Warden::Manager after_authentication callbacks

This would probably be simpler for me if Ruby was my first language, but anyway, here s my question:

利用铁路 3.1,我试图接触一些配备Devise的战备经理,每当用户迹象时,就创造新的《刑法》。 我把这一逻辑放在我的应用程序管理员身上。 问题在于,当我创立一条《宪章》时,我想给它一个用户。 我曾尝试使用“Devises”助手方法,目前是用户,但那是 t。

Most importantly, I want to know why I can t access my helper methods or methods defined in the ApplicationController from within the Warden::Manager block. But I also want to know how I can edit my code so I can use Devise s current_user method (and my current_cart method, shown below) within the block without errors like the one listed below being called.

我的守则如下:

class ApplicationController < ActionController::Base
  helper :all
  helper_method :current_user
  protect_from_forgery

  before_filter :fetch_categories

  .
  .
  .

  def current_cart
    @current_cart ||= Cart.find_by_user_id(current_user.id)
  end

  Warden::Manager.after_authentication do |user, auth, opts|
    Cart.create!(:user_id => current_user.id)
  end
end

Here s the error:

NameError in Devise::SessionsController#create

undefined local variable or method `current_user  for ApplicationController:Class
最佳回答

我真的不喜欢回答我自己的问题,但由于我感到有义务不回答问题:

我最后做的是,基本上把整个 call倒在一边。 虽然这可能与我的情况相提并论,但这里我做了些什么:

申请控制员:

before_filter :authenticate_user!, :only => :current_cart

这样,必须签署用户签名,以备打电话。 此外,还修改了目前的内容:

def current_cart
  session[:cart_id] ||= Cart.create(:user_id => current_user.id).id
  @current_cart ||= Cart.find(session[:cart_id])
end

因此,如果新车尚未存在,则现成正道。 您还可以做之前的“过滤器在可能影响到你的汽车的其他控制器中,如线性设备或产品”。

问题回答
Warden::Manager.after_authentication do |user, auth, opts|
  Cart.create!(:user_id => user.id)
end

在随后的“美容”栏中,你没有接触到目前的用户。 相反,使用新认证的用户物体作为参数。
