title: For rails app, how to render all of pages inside a different folder to another html file in view?
body: <p>I have two different folders in View folder, lets say them A and B.</p>
  
  <p>In B folder, the content is generated by scaffold, so there is 5 html.erb files inside: _form.html.erb, edit.html.erb, index.html.erb, new.html.erb and show.html.erb.</p>
  
  <p>What I need is only index.html.erb, edit.html.erb and _form.html.erb, which is because users are only allowed to edit the content and do nothing else.</p>
  
  <p>In A folder, I have only 1 index.html.erb, and I want everything shows on this file. How to render the index and form file to it? I want users could see the content of index.html.erb and they can also click 'edit' to go to the form.html.erb. And the form should be in my A folder's index file, too..</p>
