title: Help with Formtastic
body: <p>First of all I'm no native speaker and just begun with rails three days ago. Sorry for my mistakes.
  Formtastic is driving me crazy. I have three tables: user, note, receiver:</p>
  
  <pre><code>class User &lt; ActiveRecord::Base
  has_many :receivers
  has_many :notes, :through =&gt; :receivers
  attr_accessible :id, :email, :password, :password_confirmation, :remember_me
  
  class Note &lt; ActiveRecord::Base
  has_many :receivers
  has_many :users, :through =&gt; :receivers
  attr_accessible :id, :text, :user_id
  accepts_nested_attributes_for :receivers
  
  class Receiver &lt; ActiveRecord::Base
  belongs_to :user
  belongs_to :note
  attr_accessible :user_id, :note_id, :note_attributes
  
  accepts_nested_attributes_for :user
  accepts_nested_attributes_for :note
  </code></pre>
  
  <p>And here my formtastic form:</p>
  
  <pre><code>&lt;%= semantic_form_for @note do |form| %&gt;
  &lt;%= form.inputs do %&gt;
    &lt;%= form.input :text %&gt;
    &lt;%= form.input :user_id, :as =&gt; :check_boxes, :collection =&gt; User.find(:all, :conditions =&gt; ["id != ?", current_user.id], :order =&gt; 'id').collect{|u| [u.email, u.id]} %&gt;
  &lt;% end %&gt;
  &lt;%= form.buttons %&gt;
  &lt;% end %&gt;
  </code></pre>
  
  <p>Now I want to create a new note which can have several receivers. Unfortunately only the note is created, but no entrys in the receiver table, even if I select receivers. Can someone help me please?</p>
  
  <p>Here my notes_controller:</p>
  
  <pre><code>@note = Note.new(params[:note])
  </code></pre>
