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::Role::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.
