=head1 NAME
HTML::FormFu::Constraint::DateTime - DateTime constraint
=head1 VERSION
version 2.07
=head1 SYNOPSIS
---
elements:
- type: Text
name: start_date
constraints:
- type: DateTime
parser:
strptime: '%d-%m-%Y'
- type: Text
name: end_time
constraints:
- type: DateTime
parser:
regex: !!perl/regexp '^(\d{2}) - (\d{2}) - (\d{4})$'
params: [day, month, year]
An example of using the same parser declaration for both a DateTime
constraint and a DateTime inflator, using YAML references:
---
elements:
- type: Text
name: date
constraints:
- type: DateTime
parser: &PARSER
strptime: '%d-%m-%Y'
inflators:
- type: DateTime
parser: *PARSER
=head1 DESCRIPTION
Ensure input can later be inflated to a DateTime object.
=head1 METHODS
=head2 parser
Arguments: \%args
Required. Define the expected input string, so L<DateTime::Format::Builder>
knows how to turn it into a L<DateTime> object.
Accepts arguments to be passed to L<DateTime::Format::Builder/parser>.
