SYNOPSIS

12         ---
13           elements:
14             - user_id
15             - user_name
16             - type: Repeatable
17               nested_name: addresses
18               elements:
19                 - type: Hidden
20                   name: id
21                 - street

24         $form->model('HashRef')->default_values( {
25           user_id => 123,
26           user_name => 'Hans',
27           addresses => [
28             { id => 2,
29               street => 'Somewhere' },
30             { id => 3,
31               street => 'Somewhere Else' }
32           ]
33           } );
34
35         $form->default_model('HashRef');
36         my $hashref = $form->model->create();
37
38         # $hashref is very much the same as the hashref you passed to default_values()

DESCRIPTION

41       If you need the content of a formular as hashref or for processing with
42       other modules like "JSON" you can use this model.
43

METHODS

45   create
46       This method creates a hashref from a filled form. This form can be
47       filled by calling "default_values" in HTML::FormFu, default_values of
48       any other model class (e. g. HTML::FormFu::Model::DBIC) or by simply
49       submitting the form.
50
51       If "deflators" is true all deflators are processed (defaults to 1).
52
53       If "options" is true the value of all elements which have options like
54       HTML::FormFu::Element::Select will be transformed.
55
56         ---
57           elements:
58             - type: Select
59               name: select
60               options:
61                 - [1, "Foo"]
62                 - [2, "Bar"]
63
64       If the value of "select" is 1, create will create this hashref:
65
66         { 'select' => { label => 'Foo', value => 1 } }
67
68       If there is more than one value selected, an arrayref is created
69       instead:
70
71         { 'select' => [ { label => 'Foo', value => 1 },
72                         { label => 'Bar', value => 2 } ] }
73
74       If "options" is false, the output will look like this:
75
76         { 'select' => 1 }
77
78       respectively
79
80         { 'select' => [1, 2] }
81
82       "options" is false by default.
83
84       To get a flattened hash, you can set "/flatten" to a true value
85       (defaults to 0).  This will generate a hash which uses the nested name
86       of each field as key and the value of this field as hash value. If
87       there is a field which has more than one value, a counter is added. The
88       above example would result in a hash like this using "/flatten":
89
90         { 'select_0' => 1,
91           'select_1' => 2 }
92
93   update
94       Alias for "create".
95
96   default_values
97       Populate a form using a hashref. This hashref has the same format as
98       the output of "create".  If "inflators" is true, all inflators will be
99       processed (defaults to 1).
100

CONFIGURATION

102       These methods do not return the model object so chaining is not
103       possible!
104
105   options
106       Adds the label of a value to the hashref if the element has "options"
107       in HTML::FormFu::Role::Element::Group.  See "create" for an example.
108       Defaults to 0.
109
110   flatten
111       Flattens the hash using Hash::Flatten. See "create" for an example.
112       Defaults to 0.
113
114   deflators
115       If true, processes deflators in "/create". Defaults to 1.
116
117   inflators
118       If true, processes inflators in "/default_values". Defaults to 1.
