title: How to setup cancancan abilities
body: <p>Having trouble figuring out how to set up my different roles with cancancan abilities. I have a model "Business" which has many users with a role of either :owner, :manager or :employee.<br>
  Im trying to make it first that if they don't belong_to that business they can't see anything for that business.  And second I want to limit functionality based on which role they have. </p>
  
  <p>I guess I could do this within the views by using if statements and only showing them the things they have access to, but wondering if there is a better way with cancan</p>
