title: How do you pass data between models in Ruby on Rails
body: <p>I have a controller and I current have it using redirect going to another controller, I know I can pass data around using the :query... </p>
  
  <p>Is there any way I can do this without the use of http as I'm finding it impossible to send a hash using http.</p>
  
  <p>I cant find this information any where, what is the most common way of sharing data (slash sending) data from one controller to another?</p>
  
  <p>please help been working on this for hours, btw am new to RoR</p>
