Can't call method "run" on an undefined value
|
|
When I create and run a new Catalyst app form the CPAN tutorial, I get
the following error:
Can't call method "run" on an undefined value at
C:/Perl/site/lib/Catalyst.pm line 2094.
I am using Windows XP with MS SQL Server Express 2008 and a fresh
install of Catalyst.
When I port over a catalyst app i havce created on my Linux box, it
runs. The failure only occurs on apps I create on the Windows box. I am
not very far along in the tutorial when I am trying to run this. I don't
even have it connected to a database yet.
Also, I'm not sure if this is related or not, but the app I ported over
can connect to the MS SQL database using ODBC ( dbi:ODBC:ConnectName
). The app works fine and pulls and saves data properly. However, when
I make a change to the database and need to reflect that change in
Catalyst, I seem to be unable to connect. I run the following command,
but it does not create the Schema files as I would expect.
script\myapp_create.pl model DB DBIC::Schema MyApp::Schema create=static
components=TimeStamp,EncodedColumn dbi:ODBC:MyAppDB user1 password1
This will create a lib\MyApp\Model\DB.pm file and a lib\MyApp\Schema.pm
file. The schema.pm file has the proper load_namespaces instead of
load_classes. However, I don't get any files in my lib\MyApp\Schema
directory or lib\MyApp\Schema\Result directory. I have no idea why. I
originally thought it had something to do with my SQL Server
permissions, but now I'm not sure. They might be the same problem.
