Date Field Autoupdate

Hey All,

I am in the process of trying to run a script that turns text input
fields into the date field with Year, Month, Day only. I can
correctly pull the data and reformat it from the text input fields
without problems so far. I have it in an array. How do I go about
programatically adding the new date field to each story that I want to
and then setting it with the right date. I've taken a look at the API
and can't seem to understand. I think the fact that it is a date
input adds a degree of complication. Any help would be appreciated!

Re: Date Field Autoupdate [In reply to]

Okay, so I am successfully now updating the fields with my script
using this code:

my $article_date =
Bric::Biz::ElementType::Parts::FieldType->lookup({ id => 1934 });
$story = $story->add_field($article_date, 'YYYY-MM-DD hh:mm:ss');

Where 1934 is the ID of the element that I want to add and where the
time is an actual value. Now I am running into the problem that it
will not let me delete my old elements, this is the code that I am
trying to use:

foreach $element ($story->get_elements){
if($element->has_name('date')){
$element->do_delete;
$element->save;
}
}

But it keeps returning this error:
Can't locate object method "do_delete" via package
"Bric::Biz::Element::Field"

Any help would be greatly appreciated.

-Trevor

ps - I hope someday I'll know enough to help people on this list
instead of constantly asking questions :)

Have a look at the API docs for Bric::Biz::Element::Container-
>delete_elements(). I think the element has to be deleted via its
container, not from the element itself (i.e. tell the container to
delete an element inside rather than tell the element to delete itself).

The code that handles this when you delete elements in the UI is in
Bric/App/Callback/ContainerProf.pm. I usually find it helpful to "see
how the UI does it" and then copy/modify to suit.

Re: Date Field Autoupdate [In reply to]

I'm now trying to delete things as you mentioned by category using this code:

my $cat = $story->get_primary_category->get_id;
my @stories = Bric::Biz::Asset::Business::Story->list({ site_id
=> $story->get_site_id, category_id => $cat, active => 1, unexpired =>
1, publish_status => 1, element_key_name => 'news_release' });
foreach my $story (@stories){
$story->delete_elements({ id => 1354 });
}

But I am still getting this error:

Can't locate object method "do_delete" via package
"Bric::Biz::Element::Field"

Thanks,
Trevor

Re: Date Field Autoupdate [In reply to]

Okay so this is really weird but I just commented this line out of my code:
$story->delete_elements({ id => 1354 });

And I am still getting the error:
Can't locate object method "do_delete" via package
"Bric::Biz::Element::Field"

I did a search on the string 'do_delete' and nothing showed up in my
code. I've attached my whole code just in case you think you can
help. Thanks.

Re: Date Field Autoupdate [In reply to]

Okay, so apparently that last error was caused by a weird Bricolage
caching error of some sort, but now my template code is again actually
being the one called for preview. And with this method:
> $story->delete_elements({ id => 1354 });
I am still getting this error:
> Can't locate object method "do_delete" via package "Bric::Biz::Element::Field"
Help anyone?

I've no idea what's happening there, but if what you want is to delete
the "mumble" fields associated with the top-level element of those
stories, you'd have to do this:

foreach my $story (@stories) {
my $elem = $story->get_element;
if (my @fields = $elem->get_fields('mumble')) {
$elem->delete_elements(\@fields);
$elem->save;
}
}

Note how I'm finding the fields to delete using key name rather than
an ID.

HTH,

David
