( [id://3333]=superdoc: print w/replies, xml ) Need Help??
The following code tells me that no new sub can be found in package STRTicket. While true technically... the @ISA is supposed to enable inheritance... I thought. In this case the empty sub class fails.

All classes are in the same monolithic source file. USE doesn't appear to like that and searches for actual .pm files... so I used import which seems to give me the symboltables (Ticket->new works for instance... but inheritance appears to fail ( Empty sub-class test fails). So What... if anything else am I supposed to do when everything is in a single file to use an object and its subclasses?

my $t = new STRTicket(); package Ticket; sub new { my $class = shift; my $ticketid = shift; my $self= { 'TICKETID' => undef, 'SOURCE' => undef, 'CREATEDBY' => undef, 'OWNER' => undef, 'MODIFIEDBY'=> undef, 'CREATEDON' => undef, 'MODIFIEDON'=> undef, 'COMPANYNAME'=> undef, 'STATE' => undef, 'STATUS' => undef, 'BZTICKETS' => (), 'AGE' => undef, 'TITLE' => undef, }; bless $self, $class; if ( defined $ticket) { $self->{'TICKETID'} = $ticket; } else { die "Ticket object instantiated without a ticket id! This shou +ld never happen.\n"; } return $self; } sub load_bztickets($){ my $self= shift; my $dbh = shift; # pass in the database reference for Bugzilla } 1; package BZTicket; import Ticket; # use Ticket; @ISA = ('Ticket'); 1; package CRMTicket; import Ticket; #use Ticket; @ISA = ('Ticket'); 1; package STRTicket; import Ticket; # use Ticket; @ISA = ('Ticket'); 1;

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
