Question

我的rails3应用程序安装了declarative_authorization和inherited_resources gems。让我告诉你我的应用程序中的一些代码：

class Blog < ActiveRecord::Base
  has_many :posts
  has_many :memberships, :class_name => "BlogMembership"

  has_many :subscribers, :through => :memberships, :source => :user, :conditions => "blog_memberships.membership_type = #{BlogMembership::SUBSCRIBER} or blog_memberships.membership_type = #{BlogMembership::AUTHOR} or blog_memberships.membership_type = #{BlogMembership::MODERATOR}"
  has_many :authors, :through => :memberships, :source => :user, :conditions => "blog_memberships.membership_type = #{BlogMembership::AUTHOR} or blog_memberships.membership_type = #{BlogMembership::MODERATOR}"
  has_many :moderators, :through => :memberships, :source => :user, :conditions => "blog_memberships.membership_type = #{BlogMembership::MODERATOR}"
end


class Post < ActiveRecord::Base
  belongs_to :blog, :counter_cache => true
  belongs_to :author, :class_name => "User", :foreign_key => "user_id"
end


class BlogMembership < ActiveRecord::Base
  belongs_to :user
  belongs_to :blog

  # Membership types:
  SUBSCRIBER = 0
  AUTHOR = 1
  MODERATOR = 2
end

我的授权规则：

authorization do
  role :guest do
    description "Not logged in users and users not assigned to any group"

    ##### Blogs and Posts
    has_permission_on :blogs, :to => [ :read, :list ]

    has_permission_on :posts, :to => [ :read, :feed ]
    has_permission_on :posts, :to => :flag if User.current
  end

  role :admin do
    description "Administrators"
    has_omnipotence # Can manage all
  end

  role :moderator do
    description "Blog moderators"

    includes [ :guest, :blogger ]

    has_permission_on :posts, :to => :manage do
      if_attribute :blog => { :moderators => contains { user } }
    end
  end

  role :blogger do
    description "Blog authors"

    includes :guest
    has_permission_on :posts, :to => :create do
      if_attribute :blog => { :authors => contains { user } }
    end
    has_permission_on :posts, :to => :manage do
      if_attribute :author => is { user }
    end
  end
end

privileges do
  # default privilege hierarchies to facilitate RESTful Rails apps
  privilege :manage, :includes => [:create, :read, :update, :delete]
  privilege :read, :includes => [:index, :show]
  privilege :create, :includes => :new
  privilege :update, :includes => :edit
  privilege :delete, :includes => :destroy
end

在posts / index.html.haml中我使用

- if permitted_to? :create, :posts
  .button.add-post
    = link_to "New post", new_resource_path

和我的posts_controller

class PostsController < InheritedResources::Base
  respond_to :html

  belongs_to :blog
  filter_access_to :all
end

看起来不错，但不起作用：（

测试用户拥有主持人的角色，主持人是其中一个博客的成员，但没有第二个博客的任何会员资格。

使用以下规则和代码，任何具有版主角色的用户都可以在任何博客中创建帖子。

你能告诉我 - 我需要改变什么才允许博客作者和版主将帖子发送到他们的博客而不是其他博客？

Answer 1

不是那么优雅的方式，但我用以下方法解决了这个问题：

更改了posts_controller中的访问过滤器：

filter_resource_access：nested_in =＆gt; ：博客
添加了发布控制器的方法

保护

def new_post_for_collection @post = Blog.find（params [：blog_id]）。posts.new 端
index.html.haml中的更改
- if allowed_to？：create，@ post .button.add员额 = link_to“新帖子”，new_resource_path

declarative_authorization包含和继承的资源
