Save int, but display text

Question

I’m studying Cake and I have a question, have some way to display a list, but save a number in the comic?

For example, permission levels:

0 - admin
1 - vendas
2 - Edição
3 - Financeiro

In all views should appear only the text, but when saving save the number.

Answer 1

You can use the Entity for this, through a virtual field. Leave your field (which is saved in the bank) as Hidden, and create a new field (with another name) as virtual.

Dai, creates a Setter that takes the value in string, transforms it into number and saves the data in the database field, and a getter takes the database number and returns the string.

It would be something like that:

class User extends Entity
{
    protected $_hidden = ['permissoes'];
    protected $_virtual = ['cargo'];

    protected function _getCargo()
    {
        $dicionario = [
            0 => 'admin', 
            1 => 'vendas', 
            2 => 'Edição',
            3 => 'Financeiro'
        ];
        return $dicionario[$this->_properties['permissoes']];
    }
    protected function _setCargo($cargo)
    {
        $dicionario = [
            'admin' => 0, 
            'vendas' => 1, 
            'Edição' => 2,
            'Financeiro' => 3
        ];
        return $dicionario[$cargo];
    }
}
