So we have created the two required lists. Now let us display it to the user.

Refining the View

The first step in displaying both the lists is to create a template in the app/views/users folder. Let us name it display_assign.rhtml. It will contain code to show two combo boxes—one for showing the users and another for showing the roles. Apart from that we need to give the submit button to submit the selected values to the Controller. The code is identical to what you have seen for displaying the list of genres in the 'New Tale' page. The following is the code:

<h1>Assign Role</h1> <% form_tag :action => 'assign' do %> <p><label for="user_user_name">User<br/> <select name="user"> <% @users.each do |user| %> <option value="<%= user.id %>"> <%= user.user_name %> </option> <% end %> </select> </p> <p><label for="role_role_name">Role<br/> <select name="role"> <% @roles.each do |role| %> <option value="<%= role.id %>"> <%= role.name %> </option> <% end %> </select> </p> <%= submit_tag "Assign Role" %> <% end %> <%= link_to 'Back', :action => 'list' %>
