HTML::FormFu::Model::HashRef - handle hashrefs

VERSION

version 2.07

SYNOPSIS

  ---
    elements:
      - user_id
      - user_name
      - type: Repeatable
        nested_name: addresses
        elements:
          - type: Hidden
            name: id
          - street


  $form->model('HashRef')->default_values( {
    user_id => 123,
    user_name => 'Hans',
    addresses => [
      { id => 2,
        street => 'Somewhere' },
      { id => 3,
        street => 'Somewhere Else' }
    ]
    } );

  $form->default_model('HashRef');
  my $hashref = $form->model->create();

  # $hashref is very much the same as the hashref you passed to default_values()

DESCRIPTION

If you need the content of a formular as hashref or for processing with other modules like "JSON" you can use this model.

METHODS

create

This method creates a hashref from a filled form. This form can be filled by calling "default_values" in HTML::FormFu, default_values of any other model class (e. g. HTML::FormFu::Model::DBIC) or by simply submitting the form.

If "deflators" is true all deflators are processed (defaults to 1).

If "options" is true the value of all elements which have options like HTML::FormFu::Element::Select will be transformed.

  ---
    elements:
      - type: Select
        name: select
        options:
          - [1, "Foo"]
          - [2, "Bar"]

If the value of "select" is 1, create will create this hashref:

  { 'select' => { label => 'Foo', value => 1 } }

If there is more than one value selected, an arrayref is created instead:

  { 'select' => [ { label => 'Foo', value => 1 },
                  { label => 'Bar', value => 2 } ] }

If "options" is false, the output will look like this:

  { 'select' => 1 }

respectively

  { 'select' => [1, 2] }

"options" is false by default.

To get a flattened hash, you can set "/flatten" to a true value (defaults to 0). This will generate a hash which uses the nested name of each field as key and the value of this field as hash value. If there is a field which has more than one value, a counter is added. The above example would result in a hash like this using "/flatten":

  { 'select_0' => 1,
    'select_1' => 2 }

update

Alias for "create".

default_values

Populate a form using a hashref. This hashref has the same format as the output of "create". If "inflators" is true, all inflators will be processed (defaults to 1).

CONFIGURATION

These methods do not return the model object so chaining is not possible!
