OK Ive created a Subscription model, and expect somewhat to hang stuff off there

class Subscription < ActiveRecord::Base
  belongs_to :user
  belongs_to :page
end

There is an indexed id in the table cause I created it thus

class CreateSubscriptionsTable < ActiveRecord::Migration
  def change
    create_table :subscriptions do |t|
      t.integer :page_id
      t.integer :user_id
    end
    add_index :subscriptions, :page_id
    add_index :subscriptions, :user_id
  end
end

---------------

class User #...

  has_many :subscriptions
  has_many :pages, through: :subscriptions

----------------

class Page # ..

  has_many :subscriptions
  has_many :users, through: :subscriptions

  def subscribe(usr)
    self.users << usr unless self.users.exists?(usr)
  end

-------------------

Failing test, note creating a page adds the page creator to the subscribers (currently, the users) for a page

describe 'Subscription' do

  let(:user) {FactoryGirl.create(:user) }
  let(:user1) {FactoryGirl.create(:user) }
  let(:page){ FactoryGirl.create(:page, title: 'first title', user: user, content: 'any' ) }

  it "should keep track of subscribed pages for several users" do
    user.pages.should == [page]
    user1.pages.should == []
    page.subscribe(user1)
    page.users.should == [user, user1]
    user.pages.should == [page]
    user1.pages.should == [page]       # <------------ fails here
  end


expected: [#<Page id: 1, created_at: "2014-06-28 16:00:27", updated_at: "2014-06-28 16:00:27", 
             slug: "first-title", title: "first title", lock_version: 0, page_type: nil, moscow: "Not set yet">]
     got: #<ActiveRecord::Associations::CollectionProxy []> (using ==)

------------------

For reference these low level tests pass:

  it "should subscribe page creator" do
    page.users.count.should == 1
    page.users.last.should == user
  end

  it "should add a subscriber" do
    page.subscribe(user1)
    page.users.count.should == 2
    page.users.first.should == user
    page.users.last.should == user1
  end

  it "should add a subscriber once only" do
    page.subscribe(user)
    page.subscribe(user1)
    page.subscribe(user1)
    page.users.count.should == 2
    page.users.first.should == user
    page.users.last.should == user1
    user.pages.should == [page]
  end

---------------

problem 2 I have yet to get something like the following working

class Page # ..

  has_many :subscriptions, class_name: :user
  has_many :subscribers, through: :subscriptions

no matter which line I put class_name on... but that may be that I need to carefully read documentation
