This was what I thought and am trying to avoid, I am doing my best to keep
concern with SQL trot he Model and any action/method that requires data to use
the Model and have the business logic kept in the Model, so that only
actions->routes and the additional application helper methods are in the
controller.
I have read and seen frameworks such as Mojolicious encourage a shrinkage of
the Model and move alot of functionality to the Controller, so there is a
paradigm which seems to imply it is ok to do more stuff in the Controller, but
I am leaning towards having the main code in the Model and then bolting it
together via the Controller.
So for example the authentication for the user is in the Controller but it
simply utilises the Model
EG.
sub AuthenticateUser {
my ( $self, $c ) = @_;
$c->session;
if(!$c->model('Members')->LogCheck($c)){
$c->forward('/login/login');
}
}
Dunno, this is all new to me and I'm refactoring as I go, so I doubt I'll get
it right first time! Does anyone?

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?
