In order to make my Models available on each Controller. Of course, I could
create a CGI::App package, add all the use lines there and base all my
Controllers on that package. Sure, less lines to type on each Controller.
But, every time I create a new Model, I need to make sure I added it on that
base package. Which I found annoying.
So, the question is: Does anyone knows a way to *solve* this ( I understand
it's not really a problem, but more a matter of personal preference ) other
than having a CA based package including all the packages under Models/ and
make all the Controllers inherit from that package?
Well, one way is to use a method which returns either a stashed or
newly-created model object, like this:
package MyApp::Base;
sub model {
my ($self, $classname) = @_;
# return stashed package object if it exists:
if ( my $stashed = $self->stash->{"model::$classname"} ) {
return $stashed;
}
my $package = "MyApp::Model::$classname";
unless (eval "require $package") {
$self->error("Unable to load module [$package].");
}
# instantiate object
my $model = $package->new()
|| $self->error("unable to instantiate [$package].");
# stash for future calls:
$self->stash->{"model::$classname"} = $model;
return $model;
}
Then each controller inherits from MyApp::Base (you don't even strictly
need that level of complexity), and its methods call the model methods
as eg $self->model('User')->some_method(\%args), where 'User' equates to
MyApp::Model::User, and contains all the user-related methods. And I
don't have to worry about adding new Model classes to any list of
modules, just call them as required. Not sure if that exactly chimes
with what you wanted though.
