title: Getting "path" info from the model
body: <p>**Update: i actually have a pretty good reason. I have a notify class that sends out links to users. So i need to have the URL information in there, simply for the very same routing reasons as the front end ;)</p>
  
  <p>how do i get "path" routes when i am in the model?</p>
  
  <pre><code>users_path(xxx)
  app.users_path(xxx)
  </code></pre>
  
  <p>Both of this fails</p>
