Re: [cgiapp] Splitting large projects.

Hi,

That sounds pretty complicated to me. How about something like this?

sub hold_page {
        
# just use this to set hold
my $self=shift;
my $q = $self->query();
my $ord_num = $q->param("ordnum");

my $holdobj = Holds->new(OrdNum         => $ord_num,
                        HoldReason      => 'Manual');

if ( $holdobj->setHold() ){
        
return parse_header($self,$q->param('instance')) . "HOLD SET for $ord_num";     
        
}

        
}


It cleans things up a lot, I use the Holds module for all things "Holds" related so it is not just for this one purpose.  I also don't see the big problem with passing your query data around. That is what references are for. I do this kind of thing a lot for report queries also where each method is a query in the module and the module's queries share one display method. I guess the only other thing to look into is AUTOLOADER if you are getting into a situation where you have so much code you really would not want it all included at once. I just started learning about that. I see it used in a lot of cpan modules. 


Thanks,

Eric
