[Dbix-class] result testing

[Ronald J Kimball]

The call to $rs->first returns undef, so you're trying to call 
undef->id.  That's why you get the error.  Is that enough of a hint?  :)


Try this:

myErrorFunc() unless $rs->first;


If id is a primary or unique key, you could do this instead:

myErrorFunc() unless $c->model('AppModelDB::Clients')->find({id=>$id});
