Cakephp Model Validation decimal value

Question

I am trying to validate a decimal value, i do use naturalNumber but did not recognize a value as 1,00 as greater than zero.

How can i work with decimal values using Cakephp 2 validation ? (0,01) would be accepted!

I try :

$this->loadModel('SomeModel');    
$data = array(
    'decimal_value' => '0,01',
); 

$this->SomeModel->save($data);

class SomeModel extends AppModel {
    public $validate = array(
            'naturalNumber' => array(
                'rule' => 'naturalNumber',
                'message' => 'Value must be grater than 0',
                'required' => true
            )
        )
    );
}

without knowing cakephp 2 validation.. 0,01 is not a natural number. also possibly you need to use a dot instead of comma for decimals. commas are to separate thousands. — at0mzk

Decimals aren't natural numbers, natural numbers do not have fractions. Also 0,01 doesn't validate, Validation::naturalNumber('0,01') returns false.

If you want to validate decimals, use for example the decimal rule (and if you do make sure that you set the proper locale if you expect commas as decimal separator), or even a custom regex.
