=head1 NAME
HTML::FormFu::Deflator::Strftime - Strftime deflator
=head1 SYNOPSIS
$form->deflator( Strftime => 'start_time' )
->strftime( '%d/%m/%Y' );
---
elements:
- type: Text
inflators:
- type: DateTime
parser:
strptime: "%Y/%m/%d"
deflator:
- type: Strftime
strftime: "%Y/%m/%d"
=head1 DESCRIPTION
Strftime deflator for L<DateTime> objects.
When you redisplay a form to the user following an invalid submission,
any fields with DateTime inflators will stringify to something like
'1970-01-01T00:00:00'. In most cases it makes more sense to use the same
format you've asked the user for. This deflator allows you to specify a
more suitable and user-friendly format.
This deflator calls L<DateTime>'s C<strftime> method. Possible values for
the format string are documented at
L<http://search.cpan.org/dist/DateTime/lib/DateTime.pm#strftime_Patterns>.
If you set the form's locale (see L<HTML::FormFu/locale>) this is set on the DateTime object. Now you can use C<%x> to get the default date or C<%X> for the default time for the object's locale.
