I have 3 tables

users
educations
educactions_users

The educactions_users is my join table, with the columns users_id and 
educations_id.

A part of the user-edit-view looks like this, where the user can 
specified there   educations. This works..after getting grey hair!!

<h4>educations</h4>
    <% for education in Education.find(:all) %>
  <div>
    <%= check_box_tag "user[education_ids][]", education.id, 
@user.educations.include?(education) %>
    <%= education.name%>
  </div>
  <% end %>

But.....

In the show-view i want a list of educations wich the user has selected. 
I thought this.

 <h4>Educations</h4>
      <ul>
      <% @user.educations do |education| %>
        <li><%= education.name%></li>
      <% end %>
      </ul>

This get empty value..

This is my problem..

Grtz..remco
