[Catalyst] PAR Deployment
Hi all, I am quite new to the framework and was trying to deploy my application as a PAR archive. I have tried to follow all the different ways from the Advent Calendars and also as per PAR::Tutorial and I can't seem to get this to work. I'm sure there have been successful deployments using this method. So, can someone please point me in the right direction for deploying a Catalyst application as a PAR. The servers I'm trying this on are: 1. Mac OS X 10.4.8 (Tiger) 2. Linux i686 GNU/Linux Thanks, Adeola. -- Creative Developer - Digital Craftsmen Ltd Exmouth House, 3 Pine Street London, EC1R 0JH t: +44 20 7183 1410 f: +44 20 7099 5140 m: +44 79 3952 0786 w: http://www.digitalcraftsmen.net/ ___ List: Catalyst@lists.rawmode.org Listinfo: http://lists.rawmode.org/mailman/listinfo/catalyst Searchable archive: http://www.mail-archive.com/catalyst@lists.rawmode.org/ Dev site: http://dev.catalyst.perl.org/

I think this needs to be:
[% Catalyst.config.name %]
I call template like this:
$c->stash->{template}->'books/view.tt2';
And this needs to be:
$c->stash->{template} = 'books/view.tt2';
HTH,

[Catalyst] Changing the request->user_agent

[Catalyst] internal redirect
Hi all,
Is there a way to do an internal redirect in Catalyst?
In my application I'm generating images on the fly and want to
redirect to the image if creation succeeds.
For instance:
$image = Imager->new()
$image->read( file => $src_file );
$new_img = $image->copy->scale( xpixels => 32, ypixels => 32 );
if ( $new_img->write( file => $new_filename ) ) {
# do internal redirect to new file here
}
I tried using "$c->response->redirect( $new_filepath )" but that
issues a 302 "Temporarily Moved" status. But what I actually want is
a way to do the redirect outside of the response chain.
I hope this is clear?!
Thanks,
Adeola.

I suspect your web document root is not the root of the file system.
Oops -- I read those as the same variable. Shows, how important it is
to use good variable names.
Are you sure $new_filepath is really where you are saving the image?
Yes, the new image is being created as $new_filepath.
By $new_filepath I mean uri_path and $new_filename is system_path.

[Catalyst] MySQL server has gone away

This problem will occur when a process forks after creating a DBI connection, since the connection becomes invalid in the child process. See the code in Catalyst::Model::DBI for ways to handle this. OK. Thanks. I'll have a look and hopefully this will all be fixed. Its really strange, 'cause it worked for a short while (maybe about 12 - 24 hours) after deploying it but then it just gave up.

[Catalyst] SubRequest and template recursion
Hi all,
I have a template (page.tt2) that uses TT's VIEW directive, where I'm
making a sub-request:
[% BLOCK feed;
data = Catalyst.subreq("/feed/$feed_url");
data;
END;
%]
In my controller:
sub get_feed : LocalRegex('^(.*$) ) {
my ( $self, $c );
my $src_url = $c->request->captures->[0];
my $content = get($src_url); # already USE(ing) LWP::Simple above
$c->stash->{source_string} = $content;
$c->stash->{template} = 'feed.tt2';
}
But instead of a return of the results of running the source through
the feed.tt2 template I get an error "file error - recursion into
'page.tt2'".
Any help, hints would be gratefully appreciated.
Adeola.

Re: [Catalyst] Using a custom TT filter
Hello,
In your TT::View you could add:
use base 'Catalyst::View::TT';
sub noDia {
my $text = shift;
$text =~ tr/ăşţîâĂŞŢÎÂ/astiaASTIA/;
return $text;
}
__PACKAGE__->config({
FILTERS => {
'noDia' => \&noDia,
},
});
So, in your template you should be able to use:
[% FILTER noDia -%]
data to parse
[% END %]
I hope this helps. This is just form my knowledge of TT. I'm still
getting used to Catalyst so someone else might have a better idea but
its worth a try ;)

to load "D:\web\TranzactiiBursiere\lib::Diverse::NoDia"?) at D:/usr/

How can I define a custom TT filter in a Catalyst app?
(I need to filter a text depending on a condition, and I don't know
if I can use another method for doing this.)
Thank you.

From TFM:
new()
This constructor follows the often seen named parameter method call.
Parameters you can use are: filename, parser, xml, ioref and context.
The filename parameter specifies an XML file to parse.
The xml parameter specifies a string to parse
^
Dave,
In my Template I already have that:
[%
USE doc = XML.XPath( xml => source_string );
node = doc.findnodes('/rss');
adaptation.print(node);
-%]
I also tried using 'text' as in Template::Plugin::XML::XPath docs,
with no luck.

[Catalyst] Problems forwarding to view

I'm trying to use Catayst::View::XSLT and my end sub looks like this:
# from MyApp::Controller::Root
sub end : Private {
my ( $c, $self ) = @_;
$c->forward( $c->view('XSLT') );
}
but when I make a request to the server I get an error:
[error] Caught exception in MyApp::Controller::Root->end "Can't locate
object method "view" via package "MyApp::Controller::Root" at
/Users/adeola/projects/MyApp/script/../lib/MyApp/Controller/Root.pm line
160."
I have even tried:
c->forward('MyApp::View::XSLT');
and that gives the the error:
[error] Caught exception in MyApp::Controller::Root->end "Can't locate
object method "forward" via package "MyApp::Controller::Root" at
/Users/adeola/projects/MyApp/script/../lib/MyApp/Controller/Root.pm line

Am I missing something? Any tips/leads would be greatly appreciated.
