HTML::FormFu::Model::HashRef(3pm) User Contributed Perl Documentation HTML::FormFu::Model::HashRef(3pm) NAME
HTML::FormFu::Model::HashRef - handle hashrefs 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! options Adds the label of a value to the hashref if the element has "options" in HTML::FormFu::Element::_Group. See "create" for an example. Defaults to 0. flatten Flattens the hash using Hash::Flatten. See "create" for an example. Defaults to 0. deflators If true, processes deflators in "/create". Defaults to 1. inflators If true, processes inflators in "/default_values". Defaults to 1. SEE ALSO
