title: Add new fields to Devise model. Rails 5
body: <p>So I wanna add some new fields to my Devise model User. When I was using Rails 3 I just added new fields to model and added those fields to Model.rb </p>
  
  <pre><code>attr_accessible :name, :etc  
  </code></pre>
  
  <p>and then I changed Registration view.
  Now I've done the same, but I haven't Devise/User controller so I can't do something like this</p>
  
  <pre><code> def user_params
        params.require(:users).permit(:name)
   end 
  </code></pre>
  
  <p>Or</p>
  
  <pre><code>attr_accessible :name, :etc 
  </code></pre>
