设置未知属性：yii\validators\NumberValidator::0

Question

我尝试调用一个设置表单，它显示用于将数据保存到价格数据库中的输入表单。

我的模型在渲染过程中抛出上述异常：

未知属性 – yii\base\UnknownPropertyException
设置未知属性：yii\validators\NumberValidator::0

_price-item 行错误：

$form->field($model, "[{$i}]credits")->textInput(['maxlength' => 8])

型号：

<?php

namespace app\models;


use Yii;

/**
 * @package app\models
 *
 * @property integer $id
 * @property integer $credits
 * @property integer $price
 * @property integer $reduced_price
 * @property integer $discount
 * @property string $start
 * @property string $end
 * @property integer $active

 */
class Price extends \app\base\ActiveRecord
{
    public function rules()
        {
            return [
                [['credits'], 'integer', 'required'],
                [['price'], 'integer','integerOnly' => false,'required', 'min' => 0, 'max' => 10000],
                [['reduced_price','discount'],'integer','integerOnly' => false,'min' => 0, 'max' => 10000],
                [['start','end'],'format' => 'php:Y-m-d H:i:s'],
                [['active'], 'integer'],
                [['active'], 'in', 'range' => array_keys(self::$_CONDITIONS)],
                ];
        }
}

小部件：

<?php DynamicFormWidget::begin([
            'widgetContainer' => 'wrapper-prices',
            'widgetBody' => '.container-items',
            'widgetItem' => '.item',
            'limit' => 30,
            'min' => 1,
            'insertButton' => '.add-item',
            'deleteButton' => '.remove-item',
            'model' => count($prices) ? $prices[0] : new \app\models\Price(),
            'template' => $this->render('_price-item', [
                'i' => 0,
                'form' => $form,
                'model' => count($prices) ? $prices[0] : new \app\models\Price(),
            ]),
            'formId' => 'dynamic-form',
            'formFields' => [
                'credits',
                'price',
                'reduced_price',
                'discount',
                'start',
                'end',
                'active',
            ],
        ]); ?>

mysql:

CREATE TABLE `price` (
  `id` int(11) NOT NULL,
  `credits` int(11) NOT NULL,
  `price` float NOT NULL,
  `reduced_price` float DEFAULT NULL,
  `discount` float DEFAULT NULL,
  `start` datetime DEFAULT NULL,
  `end` datetime DEFAULT NULL,
  `active` smallint(1) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

谁能告诉我，怎么了？我的头都快烧起来了

Answer 1

这是你的前 2 条规则

[['credits'], 'integer', 'required'],
[['price'], 'integer','integerOnly' => false,'required', 'min' => 0, 'max' => 10000],

您在一个错误的规则中设置了 2 个核心验证器 integer、required。 integer 例如验证器采用 max 或 min 参数，并且也作为关联数组 'min'=>10，并分配属性值，如 $obj->min=10 ，并且您的代码将强制整数验证器将 'required' 解释为 0=>'required' ，这清楚地解释了上述错误。

Unknown Property – yii\base\UnknownPropertyException Setting unknown property: yii\validators\NumberValidator::0

将规则方法更改为

 public function rules()
        {
            return [
                [['credits','price'], 'required'],
                [['price'], 'integer','integerOnly' => false, 'min' => 0, 'max' => 10000],
                [['reduced_price','discount'],'integer','integerOnly' => false,'min' => 0, 'max' => 10000],
                [['start','end'],'datetime','format' => 'php:Y-m-d H:i:s'],
                [['active','credits'], 'integer'],
                [['active'], 'in', 'range' => array_keys(self::$_CONDITIONS)],
                ];
        }

更新

你的第 4 条规则也会抛出错误

[['start','end'],'datetime','format' => 'php:Y-m-d H:i:s'],

我也更新了上面的代码块。

正确的工作规则是：

感谢穆罕默德

public function rules()
{
    return [
        [['credits','price'], 'required'],
        [['price','reduced_price','discount'],'integer','integerOnly' => false,'min' => 0, 'max' => 10000],
        [['start','end'],'datetime','format' => 'php:Y-m-d'],
        [['status','credits'], 'integer'],
        [['status'], 'in', 'range' => array_keys(self::$_CONDITIONS)],
    ];
}
