HTML::FormFu::Constraint::DateTime - DateTime constraint

SYNOPSIS

Top

    ---
    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

DESCRIPTION

Top

Ensure input can later be inflated to a DateTime object.

METHODS

Top

parser

Arguments: \%args

Required. Define the expected input string, so DateTime::Format::Builder knows how to turn it into a DateTime object.

Accepts arguments to be passed to parser in DateTime::Format::Builder.
