Hi All,
I am quite a beginner for Catalyst. When I used Chained Controller to
handle some permission pages, I met a problem
First I use this piece of code to make sure that a user is logged in, if
not, the use will be forward to the login page, and I assume after login, it
will return back to the original page
sub base : Chained('/') : PathPart('user') : CaptureArgs(0) {
my ($self, $c) = @_;
if (!$c->user_exists) {
$c->flash->{'message'} = "You need to login to view this page";
$c->forward('login');
}
$c->stash->{'resultset'} = $c->model('DB::User');
}
So in the other actions, I don't need to check the user is logged in or not
sub get : Chained('base') : PathPart("") : CaptureArgs('1') {
my ($self, $c, $id) = @_;
if ($c->user->id == $id) {
...........
}
But it did not work out as I thought so, when I try to access some page,
eg. /user/$id/view
I got a error
Caught exception in SEA::Controller::User->get "Can't call method "id"
on an undefined value
What is the problem with this code?
