Answer 1

Assuming what you have

class User < ApplicatonRecord
  has_many :courses
end

and in controller you assign @user var. You should have in view smth like that:

<p> User: <%= @user.name %> </p>
<ul>
<% @user.courses do |course| %>
  <li><%= link_to(course.name, course) %></li>
<% end %>
</ul>
