title: form_for in pages other than create and edit
body: <p>I'm new to development on rails and I needed a bit of help</p>
  
  <p>I was working on a project for cataloging projects in our college.</p>
  
  <p>I have a controller and an associated model called projects. I would like to have a form_for in the Show page of projects.</p>
  
  <p>Is that even possible? </p>
  
  <p>If so, Any idea on how I can go about this?</p>
  
  <p>Thanks</p>
