Maybe hasOne->addField() can inherit field defaults from related model?

[DarkSide666]

If somehow we could get field properties from related model, then we can put them here: https://github.com/atk4/data/blob/develop/src/Reference_SQL_One.php#L46

For example,

class Model_RequestField extends Model
{
    public $table = 'request_field';

    public function init()
    {
        parent::init();

        $this->addField('type', [
            'type' => 'string',
            'mandatory' => true,
            'enum' => array_keys($v = [
                'moment'    => 'Moment',
                'datetime'  => 'DateTime',
                'int'       => 'Integer',
            ]),
            'ui' => ['valueList' => $v],
        ]);

        // hasMany
        $this->hasMany('Field');
    }
}

class Model_Field extends Model
{
    public $table = 'field';

    public function init()
    {
        parent::init();

        $f = $this->hasOne('request_field_id', ['RequestField', 'mandatory' => true]);
        $f->addField([
            'type',
            // these properties below would be nice to inherit from related model automatically by default
            'type' => 'string',
            'mandatory' => true,
            'enum' => array_keys($v = [
                'moment'    => 'Moment',
                'datetime'  => 'DateTime',
                'int'       => 'Integer',
            ]),
            'ui' => ['valueList' => $v],
        ]);

I tried this with type but problem is that this makes it super slow. Maybe we should define inheritance explicitly.

[romaninsh]

Has one is readonly but we need this for model joining.

I think this feature would be an overkill for basic functionality.

[DarkSide666]

Yeah probably, but still nice to have at some point :)

Maybe 447 implemented this?
