# Yii2 Model hasOne & hasMany 用法

model設定關聯表 hasOne & hasMany 用法

/**
 * This is the model class for table "deposit".
 * 
 * @property integer $customer_id
 * @property integer $channel_id
 * @property string $order_sn
 * @property double $Order_amount
 *
 * @property Customer $customer
 * @property Channel $channel
 */
 
class Deposit extends BaseActiveRecord
{
    // set table name
    public static function tableName()
    {
     return 'deposit';
    }

    public function rules()
    {
     // 設定table的欄位規則
    }

    public function attributeLabels()
    {
     // 設定屬性名稱
    }
     
    public function getChannel()
    {
    	return $this->hasOne(Channel::className(), ['CID' => 'CID']);
    }

    public function getCustomer()
    {
        return $this->hasOne(Customer::className(), ['UID' => 'UID']);
    }
    
}

使用`$this->hasOne('關聯表明稱', ['關聯表欄位' => '本表欄位']);`取得相對應的資料
