Hi there:
I recently upgraded to Maypole 2.08 and discovered that it is not compatible
with the Maypole app I have been using. I'm hoping that those of you who are
more familiar with the Maypole-innards will be able to shed some light on why
I'm having the problems I am.
In the `Changes' file for Maypole 2.08 a fix is listed from Marcus Ramberg where
"Maypole::Application adds plugin classes to caller's @ISA." The effect of this
patch appears to be:
--- Application.pm (my older copy)
+++ Application.pm (Maypole SVN revision 334)
@@ -7,7 +7,7 @@
use Maypole::Config;
our @ISA;
-our $VERSION = '2.07';
+our $VERSION = '2.08';
sub import {
my ( $self, @plugins ) = @_;
@@ -28,7 +28,7 @@

warn "Loaded plugin: Maypole::Plugin::$_" if $caller->debug;
- unshift @ISA, "Maypole::Plugin::$_";
+ push @{"${caller}::ISA"}, "Maypole::Plugin::$_";
}
}
}
Now this is all fine and dandy but when I apply this patch my application breaks
with the following error:
MyApp...Debugging enabled
MyApp...Loaded plugin: Maypole::Plugin::Authentication::Abstract
MyApp...Loaded plugin: Maypole::Plugin::Config::YAML
MyApp...No DSN set in config
[error] Can't locate object method "new" via package "Class::DBI::Loader::"
(perhaps you forgot to load "Class::DBI::Loader::"?) at
/.../lib/Class/DBI/Loader.pm line 77.
BEGIN failed--compilation aborted at /.../MyApp.pm line 36.
Compilation failed in require at (eval 10) line 3.
[error] Can't call method "_table2class" on an undefined value at
/.../lib/Maypole/Model/CDBI.pm line 250.
It may help to know that I begin the Maypole app by writing:
BEGIN {
package MyApp;
use MyApp::Constants;
$ENV{MAYPOLE_CONFIG} = BINPATH . '/MyApp.yaml';
}
package MyApp;
use Maypole::Application qw(
-Debug
Config::YAML
Authentication::Abstract
-Setup
);
And that I am using Maypole::Plugin::Config::YAML 0.04 and
Maypole::Plugin::Authentication::Abstract 0.10.
Any explanations as to why this patch to Application.pm was made would be
greatly appreciated as would be any suggestions concerning how I might go about
fixing my application!
Thanks
Matt
