title: NoMethodError: undefined method `find' for "Truck":String
body: <p>Ok i want to switch the name of the model by the value of a field </p>
  
  <p>this is what i have:</p>
  
  <pre><code>type = notification.notification_type.capitalize
  post = type.find(post_id)
  </code></pre>
  
  <p>Type will be Truck, Load, or Hotload</p>
  
  <p>error:</p>
  
  <pre><code>NoMethodError: undefined method `find' for "Truck":String
  </code></pre>
  
  <p>I guess it is trying to do this:</p>
  
  <pre><code>post = "Truck".find(post_id)
  </code></pre>
  
  <p>instead of this</p>
  
  <pre><code>post = Truck.find(post_id)
  </code></pre>
