Dichiarative_Authorization's contiene e risorse ereditate

Question

Ho un'app Rails3 con dichiarative_authorization e gemme ereditate_reited_reted installate.Lascia che ti mostri qualche codice dalla mia app:

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

.

Le mie regole di autorizzazione:

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

.

in post / index.html.haml i uso

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

.

e nel mio post_controller

class PostsController < InheritedResources::Base
  respond_to :html

  belongs_to :blog
  filter_access_to :all
end

.

Sembra buono, ma non funziona: (

Test L'utente ha il ruolo del moderatore con l'iscrizione del moderatore per uno dei blog, ma senza alcuna iscrizione nel secondo blog.

Con le seguenti regole e codice qualsiasi utente con ruolo dei moderatori può creare post in qualsiasi blog.

Potresti dirmi per favore - cosa ho bisogno di cambiare per consentire solo agli autori del blog e al moderatore di inviare messaggi a loro blog ma non agli altri blog?

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
