cancancan多態關聯能力（has_many）

Question

我有嵌套的資源，我想允許部門/ 1 /列表，公司/ 1 /列表和繼續，我該怎麼做？順便說一句，進出口使用導軌5和cancancan 2.0

這裏是我的文件：

的routes.rb

resources :departments do 
    resources :lists 
    end 

    resources :lists do 
    member do 
     put :done 
    end 
    end 

    devise_for :users, :skip => [:registrations] 

    devise_scope :user do 
    root to: "devise/sessions#new" 
    get "https://stackoverflow.com/users/edit" => "devise/registrations#edit", :as => :edit_user_registration 
    patch "/users" => "devise/registrations#update", :as => :user_registration 
    put "/users" => "devise/registrations#update" 
    end 

    resources :users do 
    resources :lists 
    end 

    resources :companies do 
    resources :lists 
    end 

list.rb

class List < ApplicationRecord 
     belongs_to :listable, polymorphic: true 
    end 

department.rb

class Department < ApplicationRecord 
    has_many :lists, as: :listable 
end 

company.rb

class Company < ApplicationRecord 
    has_many :lists, as: :listable 
end 

lists_controller.rb

class ListsController < ApplicationController 
    load_resource :department 
    load_resource :company 
    load_resource :user 
    load_and_authorize_resource :list, :through => [:department, :company, :user] 

ability.rb

class Ability 
    include CanCan::Ability 

    def initialize(user) 
    user ||= User.new 

    if user.has_role? :admin 
     can :manage, :all 
    else 
     can :read, List, { :company => { :id => user.company_id } } 
     can :read, List, { :department => { :id => user.departments.first.id } } 
    end 
    end 
end 

感謝。

我還是弄不明白

有人請幫幫我。

Answer 1

嘗試：

class ListsController < ApplicationController 
    load_resource :department 
    load_resource :company 
    load_resource :user 
    load_and_authorize_resource :list, :through => [:department, :company, :user] 
end 

不lists，這將是list :)
