déclaratif_authorization contient et ressources héritées

Question

J'ai des rails3 app avec déclarative_authorisation et héritéd_resources gemmes installées.Laissez-moi vous montrer du code de mon application:

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

Mes règles d'autorisation:

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

dans les messages / index.html.haml J'utilise

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

et dans mes messages_controller

class PostsController < InheritedResources::Base
  respond_to :html

  belongs_to :blog
  filter_access_to :all
end

semble bon, mais ne fonctionne pas: (

L'utilisateur de test a le rôle de modérateur avec l'adhésion du modérateur pour l'un des blogs, mais sans adhésion au deuxième blog.

avec les règles et le code suivant tout utilisateur avec le rôle de modérateurs peut créer un article dans n'importe quel blog.

Pourriez-vous me dire s'il vous plaît - ce que je dois changer pour autoriser uniquement les auteurs de blogs et le modérateur à envoyer des messages sur les blogs, mais pas sur les autres blogs?

Answer 1

Not so elegant way, but i solved it with following:

1. changed access filter in posts_controller:

   filter_resource_access :nested_in => :blog

2. Added method to posts controller

   protected

   def new_post_for_collection @post = Blog.find(params[:blog_id]).posts.new end

3. Changes in index.html.haml

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