That's probably because of exactly what I said. the default to_s/
inspect produces output like #<ClassName: ...> but that's not legal
html so it displays as just #. If you want something useful to be
displayed that's up to you, eg <%= records.collect {|r| r.name}.join
(', ') %> (assuming what you wanted to display was the name attribute
of the records. If you want to display all the attributes you could
probably just call inspect on the attributes property of each of your
records.
