我知道这看起来似乎微不足道,但我真的无法弄明白。我开始使用Yii Framework和MySQL开发数据库应用程序。我试着按照简单的基础教程: http://www.yiiframework.com/doc-2.0/guide-start-databases.html ,但我用自己的桌子"超市"。 我收到此错误:
未知属性 - yii \ base \ UnknownPropertyException 获取未知属性:app \ models \ Supermarkets :: name
很明显,方法获取('名称')导致此错误,但我不知道如何解决此问题。
这是我的代码:
...型号/ supermarkets.php:
<?php
namespace app\models;
use yii\db\ActiveRecord;
class Supermarkets extends ActiveRecord
{
}
...控制器/ SupermarketsController.php:
<?php
namespace app\controllers;
use yii\web\Controller;
use yii\data\Pagination;
use app\models\Supermarkets;
class SupermarketsController extends Controller
{
public function actionIndex()
{
$query = Supermarkets::find();
$pagination = new Pagination([
'defaultPageSize' => 5,
'totalCount' => $query->count(),
]);
$supermarkets = $query->orderBy('name')
->offset($pagination->offset)
->limit($pagination->limit)
->all();
return $this->render('index', [
'supermarkets' => $supermarkets,
'pagination' => $pagination,
]);
}
}
...视图/超市/ index.php的:
<?php
use yii\helpers\Html;
use yii\widgets\LinkPager;
?>
<h1>Supermarkets</h1>
<ul>
<?php foreach ($supermarkets as $supermarket): ?>
<li>
<?= $supermarket->name?>
<?= $supermarket->location ?>
<?= $supermarket->telephone ?>
<?= $supermarket->fax ?>
<?= $supermarket->website ?>
</li>
<?php endforeach; ?>
</ul>
<?= LinkPager::widget(['pagination' => $pagination]) ?>
Supermarkets.db:
CREATE TABLE IF NOT EXISTS `supermarkets` (
`Name` varchar(71) NOT NULL,
`Location` varchar(191) DEFAULT NULL,
`Telephone` varchar(68) DEFAULT NULL,
`Fax` varchar(29) DEFAULT NULL,
`Website` varchar(24) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
有什么建议吗?
答案 0 :(得分:1)
你可能会失去模特Supermarkets
:
/**
* @inheritdoc
*/
public static function tableName()
{
return 'Supermarkets';
}
如果未设置方法,则默认表名为supermarkets
。因为在yii\db\ActiveRecord
集合中:
public static function tableName()
{
return '{{%' . Inflector::camel2id(StringHelper::basename(get_called_class()), '_') . '}}';
}
修改
使用从模型中删除此内容
/**
* @inheritdoc
*/
public static function tableName()
{
return 'Supermarkets';
}
并使用
<?= $supermarket->Name?>
<?= $supermarket->Location ?>
<?= $supermarket->Telephone ?>
<?= $supermarket->Fax ?>
<?= $supermarket->Website ?>
或者更好的方式。使用您的第一个代码。并更改列 - &gt;设置小的第一个字母。像那样
CREATE TABLE IF NOT EXISTS `supermarkets` (
`name` varchar(71) NOT NULL,
`location` varchar(191) DEFAULT NULL,
`telephone` varchar(68) DEFAULT NULL,
`fax` varchar(29) DEFAULT NULL,
`website` varchar(24) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
