How to add new property to model yii framework?

I have added a new column in my table ‘delivery_state’

And for using it in yii framework.

i have added this ‘delivery_state’ in model like this in following function

public function rules()


        // NOTE: you should only define rules for those attributes that

        // will receive user inputs.

        return array(

            array('buyer_id, seller_id, lta_product_id, currency_id, order_date, delivery_date, payment_date', 'required'),

            array('seller_id, currency_id', 'numerical', 'integerOnly'=>true),

            array('buyer_id, lta_product_id, quantity', 'length', 'max'=>11),

            array('unitary_price, total_price', 'length', 'max'=>10),

            array('delivery_title, delivery_address,delivery_state, delivery_city, delivery_country_id', 'length', 'max'=>255),

            array('delivery_zip', 'length', 'max'=>16),

            array('phone_number', 'length', 'max'=>24),

            array('notes', 'length', 'max'=>1024),

            array('status', 'length', 'max'=>1),

            // The following rule is used by search().

            // Please remove those attributes that should not be searched.

            array('id, buyer_id, seller_id, lta_product_id, quantity, unitary_price, total_price, currency_id, order_date, delivery_date, payment_date, delivery_title, delivery_address,delivery_city, delivery_zip, delivery_country_id, phone_number, notes, status', 'safe', 'on'=>'search'),



public function attributeLabels()


        return array(

            'id' => 'Id',

            'buyer_id' => 'Buyer',

            'seller_id' => 'Seller',

            'lta_product_id' => 'Lta Product',

            'lta_contract_id' => 'Lta Contract',

            'payment_date' => 'Payment Date',

            'delivery_title' => 'Delivery Title',

            'delivery_address' => 'Delivery Address',

            'delivery_state' => 'Delivery State',

            'delivery_city' => 'Delivery City',

            'delivery_zip' => 'Delivery Zip',

            'delivery_country_id' => 'Delivery Country',

            'phone_number' => 'Phone Number',

            'notes' => 'Notes',

            'status' => 'Status',

            'buyer_quota' => 'Buyer Quota',

            'seller_quota' => 'Seller Quota',



I have added this ‘delivery_state’ in both the function rules and attributes but i got error message property delivery_state is not defined.

Can you guys please suggest me where i am wrong…

Or anything i am missing to define…
