ruby-on-rails - 如何通过 habtm 关联设置 load_and_authorize_resource？

Question

我有要在项目上下文中显示的任务。它们通过 habtm 关联关联。所以我有三个表:projects、tasks 和 projects_tasks。

resources :projects do
  resources :tasks
end

class Project < ActiveRecord::Base
  has_and_belongs_to_many :tasks
  ...

class Task < ActiveRecord::Base
  has_and_belongs_to_many :projects
  ...

如何通过 habtm 关联设置 load_and_authorize_resource？

# ???
class TasksController < ApplicationController
  load_and_authorize_resource :project
  load_and_authorize_resource :task, :through => :project, :shallow => true
  ...

你可能想让你加入一个模型，这样一个项目 has_many :tasks, :through => : assignments
