title: set current user when creating a comment with inherited_resource rails
body: <p>I am using Rails Inherited_resource gem in my comments controller, and comments is a nested resource so:<br/>
    resources :projects do<br/>
        &nbsp;&nbsp;resources :comments do<br/>
    end<br/></p>
  
  <p>I also have a belongs_to in the comments controller:<br/>
  belongs_to :project, :finder => :find_by_project_uuid!, :class_name => "Thfz::Project", :polymorphic => true</p>
  
  <ol>
  <li><p>How can I set the comment's user association to the current_user(user_id) when its created? As user_id is not suppose to be massive assigned.</p></li>
  <li><p>I tried following:<br/>
   def begin_of_association_chain<br/>
     &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;current_user<br/>
   end<br/>
  This does set the user id correctly, but I cannot get nested resource working for Project with this.</p></li>
  <li><p>Same question come when destroy a comment, I will need to find the comment through current_user, so how to achieve this?</p></li>
  </ol>
  
  <p>So do I have to write my own create and destroy actions?</p>
  
  <p>Thanks :)</p>
