Bug: rules() "required" is generated before "*_default"

[siggi-k]

The automatic generation of rules() first generates 'required' and then 'default' values.
Consequently, default values are not considered when checking 'required'.
The 'required' rules should therefore be generated after 'default'.

Example

schema.yaml

...

      required:
        - verified
      properties:
         verified:
            type: boolean
            default: false
...

This means that "verified" must be set. If it is not passed in a form, it must be saved as false.

The succession of generic "rules".

ACTUAL STATE

'trim' => [...],
'required' => [...],
...
'verified_default' => [['verified'], 'default', 'value' => false],
...

TARGET STATE

'trim' => [...],
'verified_default' => [['verified'], 'default', 'value' => false],
// all defaults
'required' => [...],
...

Though I have already implemented the solution for this issue, I think required validation is not required for boolean with default values.

It can be achieved as

$model = new Post;
$model->loadDefaultValues();
if ($model->load($_POST) && $model->validate()) {
}

This does not really make sense, default applies if empty, using required means it can not be empty.

I would like to know your use case can be achieved by any below options?

Option 1: set default value false in database table. And Yii model validation rules, remove required rule

Option 2: can you please check if yii\validators\RequiredValidator::$skipOnEmpty and/or yii\validators\RequiredValidator::$requiredValue fixes your use case
