DIV {
MARGIN:0px;}
From: John Napiorkowski
This is the error message you get if you create
a subclass of Catalyst::View that doesn't implement a process() method.
It probably doesn't have anything to do with the name of the module...
I have tried:
perl script/myapp_create.pl view
Show
After restarting the application, it gives that
error. If I do instead:
perl script/myapp_create.pl view
Html
The application works fine after restarting it.
Am I doing something wrong?
Thanks.

I'd personally be interested in seeing what the generated files look
like. Could you attach them in your response (or post them someplace we
can see?)
Hi,
Here is the first one (Show.pm):
package
TranzactiiBursiere::View::Show;
use strict;
use warnings;
use base
'Catalyst::View';
=head1 NAME
TranzactiiBursiere::View::Show - Catalyst
View
=head1 DESCRIPTION
Catalyst View.
=head1 AUTHOR

=head1 LICENSE

itself.
=cut
1;
And here it is the second one that works
(Html.pm):
package
TranzactiiBursiere::View::Html;
use strict;
use warnings;
use base
'Catalyst::View';
=head1 NAME
TranzactiiBursiere::View::Html - Catalyst
View
=head1 DESCRIPTION
Catalyst View.
=head1 AUTHOR

=head1 LICENSE
This library is free software, you can
redistribute it and/or modify
it under the same terms as Perl
itself.
=cut
1;
If I just delete the file Show.pm and restart the
server, the program works fine, but if I put it back and restart, it gives
that error.
I have seen the same thing under Linux and
Windows.
Thanks.
As others have pointed out, when you use $c->forward(...) that target needs a
process method. I try to think of modules that I forward to as being
implementations of the "Command" design pattern, or part of a Pipeline pattern,
instead of a module that is actually instantiated and consumed. At least
that's the way I try to make sense of all the different ways you can access
Catalyst modules.
I'm guessing that the reason Html works is that you actually have a different
Html modules or Action somewhere in the path that works correctly, and it is
that module and not the new one you are creating that is getting called.
When I forward to a view I try to be very explicit like:
$c->forward($c->view('html')) || $c->log->error("Can't find the html view.");
I find this helps. So try looking in your list of installed components to see
if Html is being matched someplace else. Also please let me know what you goal
here is, that way maybe we can advise a bit better. Good Luck
