Answer 1

use partials to update particular div in view

render :partial => "fileame", :layout => false

Answer 2

You can replace a div's content with a partial like this.

render :update do |page|
  page.replace_html 'person-45', :partial => 'person', :object => @person
end

Where the div id is person-45 the partial's name is person. Also you can pass an object to your partial, in this case the object is @person. For more information please see the documentation.
