DBIx::Class + TT sucks, javascript sucks

DBIx::Class ++ TT sucks.

ok, assuming that we get a record like this:

my $topic = $c->model('DBIC')->resultset('Topic')->search( { topic_id => $topic_id } )->first;
$topic->{post_on} = &format_date($topic->post_on);

now TT has two [% topic.post_on %], one is $topic->{post_on}, another one is $topic->post_on.
TT will fetch the "$topic->post_on" but ingore the $topic->{post_on}.
if we need TT fetch the "$topic->{post_on}", we have two ways:
1. $topic->{_column_data}->{post_on} = &format_date($topic->post_on);
2. $topic->{post_on_date} = &format_date($topic->post_on); [% topic.post_on_date %]

javascript sucks.

IE will complain at:

var myAjax = new Ajax.Request( url, {
     method: 'get',
     parameters: pars,
     onSuccess: showCityResponse,
     onFailure: reportCityError,
 } );

but Firefox will not.
The reason is "onFailure: reportCityError," chomp the last ","
"onFailure: reportCityError" will work.

It's hard to debug under IE, and Firefox has "FireBug". Thank God.
