授权用户使用扫描和设计
原标题:authorizing users with cancan and devise

我有一个以Devise为创建的用户模式,它拥有一个行政管理的风气场和一个角色。 我试图创建一种能力阶层,使非行政管理用户能够根据角色拥有某些能力,但与这一进程有问题。 我设立了授权控制员:

class AuthorizedController < ApplicationController
 before_filter :authenticate_user!
 check_authorization :unless => :devise_controller?
 load_and_authorize_resource

 rescue_from CanCan::AccessDenied do |exception|
  flash[:alert] = exception.message
  redirect_to root_url
 end

end

class Ability
  include CanCan::Ability

  def initialize(user)
    if !user
    can  :read, :all
  end

  if user 
    admin_rules if user.admin?
    commenter_rules if user.role.equal?("1")
    author_rules if user.role.equal?("2")
  end     
end

  def admin_rules
    can :manage, :all
  end

  def commenter_rules
    can :manage, Data, :active => true, :user_id => user.id
  end

  def author_rules
    can :manage, Post, :active => true, :user_id => user.id
  end 
end

现在,每当我试图查阅任何网页时,它就会发出一个例外的信息:“你不能获准进入这一网页,而不能进入网站的那部分。

问题回答

我感觉到can正在正确工作。 引诱:

  1. Temporarily take out the check_authorization
  2. 添加几条内容,以便了解你具备哪些能力:

    %h1 What abilities do I have?
    %ul
      %li can?(:manage, Data)
      %li can?(:manage, :all)
      %li etc..
