如何向模型yii框架添加新属性


How to add new property to model yii framework?

我在我的表'delivery_state'中添加了一个新列

以及在yii框架中使用。

我在下面的函数中添加了这个'delivery_state'模型

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',
            'quantity' => 'Quantity',
            'unitary_price' => 'Unitary Price',
            'total_price' => 'Total Price',
            'currency_id' => 'Currency',
            'order_date' => 'Order Date',
            'delivery_date' => 'Delivery Date',
            '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',
        );
    }

我已经在函数规则和属性中添加了这个'delivery_state',但我得到了错误消息属性delivery_state未定义。

你们能告诉我哪里我错了....

或任何我错过定义…

谢谢

您应该修改数据库以包含delivery_state列。但是,如果你不打算将信息保存在db中,你可以简单地将其定义为你的模块

的属性。
<?php
class Delivery extends CActiveRecord
{
    public $delivery_state;
    /**
     * @return string the associated database table name
     */
    public function tableName()
    {
        return 'table-name';
    }

}

检查main.php文件中的'schemaCachingDuration'。如果它不是"0",那就试着把它变成"0"。在我的例子中,它起作用了。

并添加'delivery_state'规则数组'safe'。它与错误无关,但它可以帮助您在提交表单时获得所有属性。
