title: Rails: Create a form wrapper using partials
body: <p>I have a form_for in all of my views. Now I need to insert a hidden html input element in all of these views. </p>
  
  <p>Is there anyway I could specify a wrapper over form using partials where I take all the form parameters , do my own logic of inserting the hidden input element and render the rest of the block given by the views? How can I do this?</p>
