Yii2 active record model not saving data

Question

I\'ve built a simple form model & view, a simple AR model, and a simple controller. The form model assigns the correct values to the AR instance, but when I call save(),

Answer 1

Okay, I figured it out. Turns out that if you declare public attributes in your ActiveRecord model, they obscure the automatic attributes that are created by AR. Data gets assigned to your obscuring attributes but doesn't get sent into the database.

The correct AR model should have been simply this:

<?php

namespace app\models;

use Yii;
use yii\db\ActiveRecord;

class Prompt extends ActiveRecord
{
    /**
     * @return string the name of the table associated with this ActiveRecord class.
     */
    public static function tableName()
    {
        return 'prompt';
    }
}
