Custom Object-Oriented Module using HTML::Template
Hey everyone, Firstly, I apologize I sent the previous email under an incorrect subject line. I am working on my first Object-Oriented project, and have hit a slight snag. I am using HTML::Template to output within the View module, but it never outputs. I don't see any errors in the logs, I just get a blank page. Below is pertinent information including a test script with its output: OS Info: CentOS release 4.6 (Final) Package info: perl-5.8.8-11 perl-HTML-Template-2.9-1 httpd-2.0.59-1.el4s1.10.el4.centos mod_perl-2.0.3-1.el4s1.3 /home/perl/Myserver/View.pm package Myserver::View; #Setup some essentials use strict; #strict tolerance for code use Carp; #debugging use diagnostics;#more debugging use warnings; #more debugging #Loadup some needed functions use HTML::Template; sub new { my $self= shift; return $self; } sub mainpage { my $self= shift; my $template= HTML::Template->new( filename => '/home/Perl/tmpl/mainpage.tmpl', cache => 1, debug => 1, stack_debug => 1 ); print "Content-Type: text/html\n\n"; $template->output; return $self; } 1; /home/Perl/tests/View_mainpage.pl #!/usr/bin/perl -w # Test printing of the main page print "Main Page.."; #Let's load the view module use lib "../"; use Myserver::View; #Now let's load some things that are very handy use strict; #strict tolerance for code use Carp; #debugging use warnings; #more debugging use diagnostics;#even more debugging # Let's create an object my $view= Myserver::View->new; # Now, let's tell View to display the main page $view->mainpage; print ".OK"; 1; /home/Perl/tmpl/mainpage.tmpl: Test!

Re: Custom Object-Oriented Module using HTML::Template
That worked great with the test script ( print $template->output; ), but unfortunately, I'm having trouble getting the display onto a web page (via the Handler). The resulting web page is blank, with no source. Below are my Apache configs for the handler, logs, and the handler and view module's latest code. I've also included the test script code, just in case there is some obvious reason it would work and the handler won't.

Re: Custom Object-Oriented Module using HTML::Template
Hi. First, a small disgression : along with perl, comes a beautiful test tool for HTTP stuff, called "lwp-request". Like, at the command-line : lwp-request (to see the options) lwp-request -m GET -Sed "http://myserver/myURL"; (that will show you what you get as a response, without a browser getting in the way) Then, below, are you not now sending one "Content-type" too many ? It looks like you are doing it once in handler(), and once in mainpage().

Thanks for the reply.

Re: Custom Object-Oriented Module using HTML::Template
Hi. First, don't take my suggestions as gospel, I don't know the TT2 and do not really know how you're supposed to work with it. But it seems to me that this is in the wrong order : $view->mainpage; $self->content_type('text/html'); I think you should trigger the HTTP header before you generate the content. Now, whether that is the reason of your current problem or not, I haven't a clue. But I'm trying, and I'm really interested, because I am starting to want to know more about TT2 (and Catalyst) these days. So your "from-the-very beginning" approach is also very helpful to me. (And I do have a certain experience of Apache2/mod_perl2) And, re-check your lwp-request switches, you might have disabled the display of the response content (remove the -d).

Good suggestion, I moved the content_type to the top of the handler routine in Handler.pm, so it now looks like: --- sub handler { my $self= shift; $self->content_type('text/html'); my $view= Myserver::View->new(); $view->mainpage; # Obligatory stuff for the handler return Apache2::Const::OK; } --- I am still getting a blank page, though.

SetHandler modperl doesn't bind 'print' to '$r->print'. Try SetHandler perl-script, or change your code to pass in the request object and use $r->print instead of print.

FYI, for those interested, I had to do some code adjustments. There was a missing right curly bracket in Handler.pm (need to close the sub), and I wasn't loading DECLINED properly in Handler.pm. Here is the proper setup: --- package Myserver::Handler; #Setup some essentials use strict; #strict tolerance for code use Carp; #debugging use diagnostics;#more debugging use warnings; #more debugging #Handler-related stuff use Apache2::RequestRec (); use Apache2::RequestIO (); use Apache2::Const -compile => qw(OK DECLINED); #Loadup Apache2::Request so we know what's been passed to us use Apache2::Request; #Loadup the Main (Model) and View modules (staying true to the #Model/View/Control (MVC) (We are, Handler, or Control)) use lib "../"; use Myserver::Main; use Myserver::View; sub handler { # We are an instance method my $request = shift; my $view= Myserver::View->new(); if (my $output = $view->mainpage()) { $request->content_type('text/html'); $request->print($output); return Apache2::Const::OK; } else { return Apache2::Const::DECLINED; }; } 1; --- On Thu, 2008-03-13 at 16:32 +, xyon wrote: > Thank you all for your advice.
