ruby-on-rails - Rails + CanCan : User should be able to delete own photo, 但不能

Question

所以，我使用 Rails 3 和 CanCan 进行授权。我希望所有用户都能够删除他们创建的照片，我以为我的设置正确，但它不起作用...

这是我的能力等级:

class Ability
  include CanCan::Ability

  def initialize(user)

    # ONLY REGISTERED USERS CAN DO THESE THINGS
    unless user.nil?

      # ALL REGISTERED USERS CAN DO THESE THINGS
      can :read, [Photo, Context, Focus, LandUse, Vote, Rating, Comment, Profile, Article]
      can :show, Page

      # MEMBERS
      if user.has_role? :member
        can [:create, :read], Photo
        can [:update, :destroy], Photo, :user_id => user.id
        can :create, [Vote, Rating, Comment, Profile]
        can :update, [Vote, Rating, Comment, Profile], :user_id => user.id

        can [:show, :update], User do |u|
          u == user
        end
      end

      # CURATORS
      ...

      # ADMINS
      ...

    end

    # ALL VISITORS CAN DO THESE THINGS
    can :create, [User, Profile]
    can :request_invite, User
    # can :show, Page

  end
end

这是我的 Controller 操作:

def destroy
  @photo = Photo.find(params[:id])

  authorize! :delete, @photo
  @photo.destroy
  redirect_to :back, :notice => 'Photo deleted.'
end

知道这里出了什么问题吗？

Answer 1

应该是授权! :destroy, @photo 在 Controller 的 destroy 操作上。
