Redmine

For security purposes I would like to suppress the list of members in the project overview to everyone accept the project admistrators.

In app/views/projects/show.rhtml I'm trying to modify this block of code

<div class="splitcontentright">
    <% if @members_by_role.any? %>
    <div class="box">
        <h3 class="icon22 icon22-users"><%=l(:label_member_plural)%></h3>    
        <p><% @members_by_role.keys.sort.each do |role| %>
        <%= role.name %>:
        <%= @members_by_role[role].collect(&:user).sort.collect{|u| link_to_user u}.join(", ") %>
        <br />
        <% end %></p>
    </div>
    <% end %>

I believe what I need is @members_by_role.admin or something like that. I believe I can do this in projects_controller.rb in app/controller/ but it causes an error when I display the page.
