This is a repost as I had zero replies to my first email. This problem is
driving me mad but it has to be a simple solution that I just can;t see.
Can someone please tell me what the difference is between the following bits
of code ....
<!-- this outputs the correct result -->
<% @swimming_class.lessons.each do |lesson| %>
<% lesson.lesson_register.attendees.each do |att| %>
<%= att.enrollee_id %>
<br />
<% end %>
<% end %>
<!-- the following outputs
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.enrollee_id
-->
<% @swimming_class.lessons.each do |lesson| %>
<% lesson.lesson_register.attendees[0].enrollee_id %>
<% end %>
Thsnk you
