Rails - Mar 2008 - Removing an element from an array

Hey,

I''m adding objects to an array, where they are displayed elsewhere on
the page.
I went to add the remove method, called by the remove button on the
page, and it''s not functioning as I would hope. I figured this is a
straightforward thing, but I want to do it the right way.

Add in view
<%= link_to_remote ''Add'',
    :url => { :action => ''add_subject'', :id =>
subject },
    :update => ''added_subjects''%>

Add in controller
  def add_subject
    @added_subjects = find_added_subjects
    @added_subjects << Subject.find(params[:id])

    render :partial => ''added_subjects'', :layout =>
false
  end

I tried this for the remove,

View
<%= link_to_remote ''Remove'',
   :url => { :action => ''remove_subject'', :id =>
subject },
   :update => ''added_subjects'' %>


Controller
  def remove_subject
    @added_subjects = find_added_subjects
    @added_subjects.reject! { |subject| subject.id == params[:id] }

    render :partial => ''added_subjects'', :layout =>
false
  end

Thanks!
