Creating a view that display all records that belongs_to an association

I'm trying to create a view that display all records that belongs to an association and not sure on how to go about this.

I've created an erb file in view/members/showmembers.html.erb, added 'showmembers' method in members_controller.rb but when I go to http://localhost:3000/members/showmembers it says 'Couldn't find Member with id=showmembers' and its pointing to the show method in the controller *'app/controllers/members_controller.rb:29:in `show'*.

  def showmembers    
     @organization = Organization.find(1)
     @shmembers = @organization.members.all
 
     respond_to do |format|
       format.html # index.html.erb
       format.json { render json: @members }
     end
   end
 

showmembers.html.erb

    <% @shmembers.each do |shmember| %>
       <tr>
         <td><%= shmember.id %></td>
         <td><%= shmember.first_name %></td>
       </tr>
     <% end %>
 

Thanks.
