Filling Stash from Another Controller's Action

Question

I have an action in one controller that needs some db records stashed to render a table.

I have an action in a second controller that fills a very similar table, and so the data in its own stash is the same as I need for the first one.

Without duplicating a bunch of code in both controllers, is there a way to use one action to fill the stash of the other?

EDIT: In response to code request (somewhat simplified, but should get the gist across):

In Contoller::ShoppingCart

sub data : Chained('base') PathPart('') CaptureArgs(0) {
my ( $self, $c ) = @_;

my $query = DBRESULTS;
    my $count = 20;

$c->stash(
    data         => $items,
    dataRowCount => scalar @$items,
    totalCount   => $count,
    pageSize     => $pageSize,
);
}

In Controller::Vendor

sub viewform : Chained('row') Args(1) {
    my ( $self, $c, $view ) = @_;

    $c->stash(
        template => 'simpleItem.mas',
        view => $view,
    );
}

The simpleItem.mas template requires data, dataRowCount, totalCount, pageSize, so grabbing the stash from Controller::ShoppingCart::pageData would be ideal.

Could we see your code please? – gideon Jan 30 '13 at 05:40 — gideon, Jan 30 '13 at 05:40

You should be able to simply $c->forward() to the specific action you need.

sub viewform : Chained('row') Args(1) {
    my ( $self, $c, $view ) = @_;

    $c->forward('Controller::ShoppingCart', 'data', [ @optional_args ]);

    $c->stash(
        template => 'simpleItem.mas',
        view => $view,
    );
}

All the gory details, including the siblings of forward(), like detach(), go() and visit().

You could chain both actions off of another function, say in Root.pm, that would get these db records and put them in the stash for you.

i.e.:

# in Root.pm
sub get_db_stuff :Path('') :Args(0) {
    my ( $self, $c ) = @_;

    #store stuff in stash
    $c->stash->{db} = #get db records
}

Then your in your other controllers where your actions are you would need these two functions:

sub base : Chained('/get_db_stuff') PathPrefix CaptureArgs(0) {}

sub use_db_stuff : Chained('base') PathPart Args(0) {
    my ( $self, $c ) = @_; 

    #db records now accessible through $c->stash->{db}
}

Good idea, but unfortunately, they are both already pretty dependent on chains themselves, so I can't really change what they are chained to. — Ryan, Jan 30 '13 at 06:02
