# after doing an edit via update, it won't redirect_to show, it stays on edit, I am using ajax
# in the view
# so here is the code:
#
# here is how I have the routes:
  map.resources :patrocinios
#...
  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'

# here is the controller:

  def edit
    @patrocinio = Patrocinio.find(params[:id])
    respond_to do |format|
      format.html # edit.html.erb
      format.xml  { render :xml => @patrocinio }
    end
  end

  def update
    @patrocinio = Patrocinio.find(params[:id])
    respond_to do |format|
      if @patrocinio.update_attributes(params[:patrocinio])
        flash[:notice] = 'Patrocinio was successfully updated.'
        format.html { redirect_to(@patrocinio) }
        format.xml  { head :ok }
      else
        format.html { render :action => "edit" }
        format.xml  { render :xml => @patrocinio.errors, :status => :unprocessable_entity }
      end
    end
  end

# here is the view:

<h1>Editing Patrocinio: <%= @patrocinio.id %> </h1>

<% form_remote_for(@patrocinio) do |f| %>
  <%= f.error_messages %>

  <p>
    <%= f.label :logotipo_id %><br />
    <%= f.select :logotipo_id, @logotipos, :prompt  => "Select one..." %></td>
  </p>

  <p>
    <%= observe_field( :patrocinio_logotipo_id,
                       :url => { :action => :update_image_div },
                       :frequency => 1.0,
                       :update => 'logo_field_div',
                       :with => :logotipo_id ) %>


  <div id='logo_field_div'>
  </div>

  </p>

  <p>
    <%= f.submit 'Update' %>
  </p>
<% end %>
