There are two ways. You can a) change the date formatting preference,
or b) pass in a strftime format string to get_data(). The date will be
returned in your local time zone.

David,

That local_date() call was commented out in my actual code, when I pasted it
into the email and neatened it up, I accidentally uncommented it. The code
actually looks like this:

if (my $pubdate = $element->get_data('publication_date', "%B %Y")) {
$formatted_date = $pubdate;
}

Doing this, it prints nothing. If I remove the arg for the time format, it
works fine printing Month Day, Year. Does the bric time format need to be
set a particular way (ISO?) for the formatting argument to work?

Phil

Not offhand, but I *can* tell you that you don't want to call
local_date(). get_data() does that for you. So you can just do this:

my $formatted_date = $element->get_data('publication_date', "%B %Y");

HTH,

David

No. If you don't pass in the date format argument, it just looks up the
Time/Date Format preference and uses that.

What happens when you use a different date format, say "%D"?

David,

No luck, I tried a few different date formats, and still nothing. Changing
the date/time format in bric does work correctly.

Does the get_data() method look like this for you?:

sub get_data {
my ($self, $format) = @_;
my $sql_type = $self->_get_sql_type or return;
return $sql_type eq 'date' ?
local_date($self->_get('_date_val'), $format) :
$self->_get('_'.$sql_type.'_val');
}

If so, try this instead:

sub get_data {
my ($self, $format) = @_;
my $sql_type = $self->_get_sql_type or return;
return $sql_type eq 'date' ?
local_date(scalar $self->_get('_date_val'), $format) :
$self->_get('_'.$sql_type.'_val');
}

Nope. get_data() did look like that, and I changed it to the second, and
still nothing.

That should be:

if (my $pubdate = $element->get_data('publication_date', '%B %Y')) {

With double-quotes %B and %Y are interpolated at hashes. With 'use
strict' in effect this would have given you an error about not declaring
%B and %Y.

Not true. This script generates no warnings:

#! /usr/bin/perl -w
use strict;
use Bric::Util::Time qw(local_date);
print local_date(undef, "%Y %B", 1), "\n";

Hashes don't interpolate in strings. Never did. :-)

Okay, trying to replicate...

* I've set up a clean install of 1.4.1 from CVS.
* I added a date field, "big date" to the "Story" element.
* I added this line to the default /story.mc template:

<h2>Date: <% $element->get_data('big_date', "%B %Y") %></h2>

* I deploy the changed /story.mc template.
* I created a story based on the "Story" element and set a date in the
"Big Date" field, then saved it.
* I preview the story...and the date it empty!
* I change the line in /story.mc to this:

<h2>Date: <% $element->get_data('big_date') %></h2>

* I deploy the changed template.
* I preview my test story...and the date shows up!

Okay, so I've replicated the bug. Let me see if I can fix it....

Oh, duh, we're both looking in the wrong place! The $element object is
a container element, not a data element. So if we look at
Bric::Biz::Asset::Business::Parts::Tile::Container->get_data, you'll
see the problem! The second argument is the order number, not the date
format:

=item $string = $tile->get_data($name, $obj_order)

=item $string = $tile->get_data($name, $obj_order, $date_format)

So you need to pass in the date format as the third argument. Returning
to my testing...

* I change the template to look like this:

<h2>Date: <% $element->get_data('big_date', 1, "%B %Y") %></h2>

Note that the "1" can also be "undef" -- the method will change it to
"1".

* I deploy the changed /story.mc template.
* I preview my test story...and it works!

That's what you have to do-- the date format is the third parameter to
the get_data() method, not the second.

HTH,

David
