title: Must i use a polymorphic setup?
body: <p>I have a app setup question: (for a travel site)</p>
  
  <p>My models are </p>
  
  <pre><code>class User &lt; ActiveRecord::Base
  end
  class House &lt; ActiveRecord::Base
  end
  class Apartment &lt; ActiveRecord::Base
  end
  
  class Boutique &lt; ActiveRecord::Base
  end
  class City &lt; ActiveRecord::Base
  end
  class Activity &lt; ActiveRecord::Base
  end
  </code></pre>
  
  <p>I want to add a "i've been there", "i've done that", "i want to go there" ect to the user model. So when a user/visitor is by example on the activity show page there is a function where they can add the status describe above. </p>
  
  <p>Where do i start in relation with my db setup...must i use the polymorphic setup? </p>
  
  <p>Thanks..remco</p>
