Moving a subelement from one story to another

Hi. I am looking to insert a subelement from one story into another
story. I have this so far:

<%perl>
# $from_story and $to_story are definitely defined and populated.

my $from_subel = $from_story->get_container("subel");

if ($from_subel) {
my $to_subel = $to_story->add_container($from_subel);
$to_story->save();
if ($to_subel) {
print "{" . $to_subel->get_data("headline") . "}<br>\n";
} # end if
} # end if
</%perl>

When I preview the handler story I get

Can't locate object method "get_field_types" via package
"Bric::Biz::Element::Container"

I have done this successfully with fields but never with containers.
Thanks for any suggestions.

Hi,

If you search the archives and check out my github repo, you can see my
copy/paste code that i did for WHO (where it does containers).

http://github.com/brewt/bricolage/tree/master

Unfortunately, its been a while since I looked at the code and have forgotten
where everything is.

This won't work. You pass an element type to add_container, not a
container. Pass it to add_element(), instead. But clone it first:

use CLONE;
if (my $from_subel = $from_story->get_container("subel")) {
$to_story->add_element( CLONE::clone($from_subel)-
>prepare_clone );
$to_story->save;
}

You have to use CLONE::clone() because prepare_clone changes the
element in-place (basically just sets the ID to `undef`), and you
don't want to mess it up in $from_story.

HTH,

David

Sorry, make that:

$to_story->get_element->add_element( CLONE::clone($from_subel)-
>prepare_clone );

Best,

David
