授權使用cancancan的特定控制器操作

Question

我有鏈接訪問玩家的load_player視圖以訪問屬於current_user的玩家。那麼我該如何限制對沒有屬於其他用戶的俱樂部或俱樂部的current_user的load_player方法的訪問。注意我想限制訪問load_player頁面。

的routes.rb

get 'player/load_player/:id' => "player#load_player", as: :player 

player_controller.rb

class PlayerController < ApplicationController 

    before_action :authenticate_user! 
    authorize_resource :class => false 

    layout "player" 

    def load_player 
    @club_hash = Club.where({:id => params[:id]}).pluck(:club_hash).first 
    end 
end 

ability.rb

class Ability 
    include CanCan::Ability 
    def initialize(user) 
    user ||= User.new # guest user (not logged in) 

    if user.is?(:admin) 
     can :manage, :all 
    elsif user.is?(:owner) 
     can :read, all: { except: [UploadedSong]} 
     can :manage, Club, user_id: user.id 
     can :read, :load_player, id: user.id 
    elsif user.is?(:user) 
     can :read, all: { except: [UploadedSong]} 
    end  
    end 
end 

Answer 1

current_user.clubs.where(id: params[:id]).pluck(:club_hash).try(:first) 

# or add user_id inside where clause 

Club.where(id: params[:id], user_id: current_user.id).pluck(:club_hash).try(:first) 

希望這會解決你的問題:)
