Hi,
I'm new to the Catalyst architecture and have been working through some
examples to learn the ropes. However, in the application I am working on, I am
able to Update, but not Create a new record. I am using HTML::FormHandler and I
believe that the inability to Create a new record has something to do with my
setup of the Form Model. Each time I try to create a new record I get the
following error.
Caught exception in Signup::Web::Controller::users->add "Can't call method
"resolve" on an undefined value at
C:/strawberry/perl/site/lib/DBIx/Class/Row.pm line 1289."The error leads me to
believe that the new_result is not working property with the Form, because if I
remove the code and leave the "item" empty the form will generate but of course
not allow the new record to be added. Data::Dumper shows that the Item variable
looks like this:
Item: $VAR1 = bless( {}, 'Signup::Web::Model::signup::User' );
Any idea where I have went wrong so that this error is created when adding new
Records and not updates?
