Just a small FYI more than anything, which might help fill in a few gaps...
$c->dbh would need you to modify MyApp.pm, this is useful at times for creating little helper methods that you want accessible via $c, or to override existing $c methods.
The session plugin does this too, that's why $c->sessionid is available, etc. or $c->check_user_roles() when using the Authorization::Roles plugin.
I'm not sure you'd really want $c->dbh anyway, since that's doesn't sound like you would be encapsulating the Model very well, and sounds like you'd have SQL in your controller code?

Cool, thanks. Reading the tutorial I got the impression $c was always passed. Thanks for clearing that up, which is why I guess $c->dbh doesn't exist. hmm, much for me to get my head round for sure!

There's no black-magic going on, so your AuthenticateUser() sub never "magically" gets $c. In short, you'll only get $c when using the method attributes, such as :Private, :Chained, etc. On 10/29/2012 07:07 PM, Craig Chant wrote:Hi, I seem to be unable to work out why $c is never automatically passed to any of my models or methods?
