Rails - Jan 2006 - Trying to understand the difference between similar iterators

What''s the difference between these two?
Objective:
Trying to display the addresses of the students that has "has_many"
relations with addresses

<td><% @student.addresses.each {|address| "Address:
#{address.addr1}<br/>"} %> </td>   ****** did not work
<% end %>

This code worked:
<td><% @student.addresses.each do |address|%>
     <%= address.addr1 %><br/>
<% end %>

Any comments appreciated.
Thanks

Hi,
You shouldn''t need the <% end %> because you are passing in a
block.
This should work as well.

<% @student.addresses.each {|address| %>
<%= address.addr1 %><br/>
<% } %>

Well first of all, when you''re iterating through a block, you
don''t
need to have an end.  In fact it should give you some kind of error. 
Secondly, <% just evals a statement, <%= renders the output.  So your
loop should be:

<td><%= @student.addresses.each {|address| "Address:
#{address.addr1}<br/>"} %> </td>
