yii2 计算 2 价值在行动创造

Question

这是我在控制器中创建的操作

public function actionCreate()
{
    $model = new User();

    if ($model->load(Yii::$app->request->post()) && $model->save()) {
        return $this->redirect(['view', 'id' => $model->id]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

数据库：

tb_leave

id
id_employee <fk>
startdate
enddate
duration
leave_type //enum 'annual leave','medical check'

tb_employee
id
name
address
total_leave

逻辑是 // if "total_leave" >= "duration" && leave_type = "Annual Leave" 然后是 total_leave - duration。并将结果插入到tb_employee中的total_leave。

有人可以帮我解决这个问题吗？

Answer 1

将 beforeSave 函数添加到如下所示的 tb_leave 模型类并更新 total_leave 值。

/**
 * @inheritdoc
 */
public function beforeSave($insert)
{
    if (parent::beforeSave($insert)) {

        $user = User::find()->where(['id' => this->id_employee])->one();

        if($user->total_leave >= this->duration && this->leave_type = "annual Leave"){
            $user->total_leave = $user->total_leave - this->duration;
            $user->save();
        }

        return true;
    } else {
        return false;
    }
}

这个函数每次保存tb_leave前都会触发。
