Fields without validation rules are not saved?

I have a field in my table which does not need any validation rule. It’s an optional field so I didn’t added a validation to it but when I hit submit - with value in that field - is not saved. If I add a validation to the field, required for ex, the content is saved into the database. Any idea why Yii performs this way?

major method:

you can add the safe rule in your model~ even if without the field actually~

other method:

you can use $post->save(false) to skip the validate of model~

    public function rules() {

        return array(

            array('Street, Number, ZipCode, Phone, Fax', 'safe')



Yes. As to why Yii behaves like this, that’s explained here.
