[Catalyst] $row-copy causing exit from controller(!)
I'm seeing something exceedingly odd: copying data causing a premature
return from the controller, like a detach(),
foreach my $table (@chart_related_tables) {
my $rs = $ds-resultset($table);
warn copying $table for , $new_chart-uid;
for my $row ($rs-search({web_chart_spec_uid = $chart-uid})) {
warn ..row , $row-web_chart_spec_uid, $row;
$row-copy({web_chart_spec_uid = $new_chart-uid}); # XXX
}
#$_-copy({web_chart_spec_uid = $new_chart-uid})
#for $rs-search({web_chart_spec_uid = $chart-uid});
die cloned, $new_chart-uid;
}
There's no further execution past the line marked XXX: the template is
rendered from that point on. The die is never called.
I have a feeling it's something to do with has_many
Chart:
__PACKAGE__-has_many(chartview_company = 'IDL::Schema::ChartCompany'
= 'web_chart_spec_uid', {cascade_delete = 0});
If I exclude from @chart_related_tables ChartCompany it works.
**
I realize there's scads of debug I could provide but wanted to check
first this wasn't something someone had run into before. If not, what
kind of debug can I provide?

[Catalyst] Re: How to print/display some data in an end action
* Andreas Marienborg [EMAIL PROTECTED] [2008-05-01 10:50]: No point in forwarding to end, since that is done automaticly. In which case it would run twice, actually. But maybe he has a more specific `end` action and so forwarding to ::C::Root::end is actually a useful thing to do in his app. As I said, we have seen too little of the code to make any meaningful suggestions.

Is copy throwing an exception? Are you using an old version of
stacktrace?
If yes and yes: upgrade StackTrace (it eats exceptions)
If no and no: something is horribly wrong (perl -d may help)
If yes and no: see above.
I have a feeling it's the first one. Another possibility is that copy
is last-ing out of itself.

If also occasionally seen exceptions disappear without stack trace

diving and perl -d)

There's no exception. Imagine a return; and that's what is happening AFAICT.
How does one use perl -d in the context of a FastCGI instance? Any
other debugging tips?

[Catalyst] Using URIs for my app in another program
Hi all I've run into a situation that I can't find a good solution to and am hoping to solicit some ideas from people on the list here. An app I've been working on consists of two main parts - a Catalyst-based web app which provides the UI, and a daemon that does the heavy lifting. They are totally separate applications that talk to one another via database. The daemon will sometimes send emails to users when it finishes certain tasks that the users are interested in, and I want to include links in the emails that would bring the user to a Results page on the web app where they can get more information about the result of the task. So, what I would like is to be able to call $c-uri_for() from my daemon. Is there any 'sanctioned' way of doing that? If possible, I'd like to avoid loading my whole catalyst app and somehow tricking it into believing its running under the same environment as my real app. Another option is to use the database to pass URIs around. Maybe a URI table that maps finished tasks to URIs. However, I would rather just be able to arbitrarily call $c-uri_for() whenever I decide I need to include a URI in my daemon instead of having to create a table or column whenever I decide I want to send a link to a new type of resource. Any suggestions? Maybe I'm just going about it all wrong? Thanks!

Re: [Catalyst] Using URIs for my app in another program
The most straightforward method I can think of is to factor out the URIs to a common config file. You can have your daemon read in the config file and generate URIs from that. Your Catalyst application can either continue to use base to generate URIs or you can generate some special URIs from the config file as well. The problem with having your daemon load up Catalyst to generate a URI is that I'm not sure how that would work. Catalyst generates URIs given a HTTP request. No HTTP request, no base URI. Another safety measure is that you can have your Catalyst appl do a sanity check against the URI config file to make sure it doesn't become out of date (maybe a startup test request).

RE: [Catalyst] Using URIs for my app in another program
Ah, right, I need a HTTP request to get base. I wasn't thinking straight about that. I think storing links in the database is what I'll do, because that leaves the responsibility of generating URIs solely with the catalyst app. If I refactor code or move things around I don't want to have to update my daemon at all.
