Question

我收到错误：

Catchable fatal error: Argument 1 passed to Application\Controller\IndexController::__construct() must be an instance of Application\Model\PlatnosciTable, none given, called in /var/www/Paczucha_pl/vendor/zendframework/zend-servicemanager/src/Factory/InvokableFactory.php on line 32 and defined in /var/www/Paczucha_pl/module/Application/src/Controller/IndexController.php on line 21

我正试图弄清楚我的代码中出错了什么。名称刚刚从Album更改为Platnosci。

有我的档案：

Platnosci.php

namespace Application\Model;

class Platnosci
{
    public $id;
    public $artist;
    public $title;

    public function exchangeArray($data)
    {
        $this->id     = (!empty($data['id'])) ? $data['id'] : null;
        $this->artist = (!empty($data['artist'])) ? $data['artist'] : null;
        $this->title  = (!empty($data['title'])) ? $data['title'] : null;
    }
}

PlatnosciTable.php

namespace Application\Model;

use RuntimeException;
use Zend\Db\TableGateway\TableGatewayInterface;

class PlatnosciTable
{
    protected $tableGateway;

    public function __construct(TableGateway $tableGateway) {
        $this->tableGateway = $tableGateway;
    }

    public function fetchAll() {
        $resultSet = $this->tableGateway->select();
        return $resultSet;
    }

    public function getAlbum($id) {
        $id  = (int) $id;
        $rowset = $this->tableGateway->select(array('id' => $id));
        $row = $rowset->current();
        if (!$row) {
            throw new \Exception("Could not find row $id");
        }
        return $row;
    }

    public function saveAlbum(Platnosci $album) {
        $data = array(
            'artist' => $album->artist,
            'title'  => $album->title,
        );

        $id = (int) $album->id;
        if ($id == 0) {
            $this->tableGateway->insert($data);
        } else {
            if ($this->getAlbum($id)) {
                $this->tableGateway->update($data, array('id' => $id));
            } else {
                throw new \Exception('Album id does not exist');
            }
        }
    }

    public function deleteAlbum($id) {
        $this->tableGateway->delete(array('id' => (int) $id));
    }
}

Answer 1

在＆＃34; PlatnosciTable.php＆＃34;中，构造函数应该读取 -

public function __construct（TableGatewayInterface $ tableGateway） { $ this-＆gt; tableGateway = $ tableGateway; }

并从＆＃34; module.config.php＆＃34;中移除以下部分;档案 -

＆＃39;控制器＆＃39; =＆GT; [ ＆＃39;工厂＆＃39; =＆GT; [ Controller \ PanelController :: class =＆gt; InvokableFactory ::类， ]，]，

Answer 2

构造函数中预期的TableGateway声明没有正确类的use。默认情况下，它在Application\Model命名空间中查找，而类应为Zend\Db\TableGateway\TableGateway：

namespace Application\Model;

// Add this to point TableGateway in __construct()
use Zend\Db\TableGateway\TableGateway;

// ...

class PlatnosciTable
{
    protected $tableGateway;

    // Now it should use a correct hinting
    public function __construct(TableGateway $tableGateway) {
        $this->tableGateway = $tableGateway;
    }

    // ...
}

Answer 3

还有一件事，在module.config.php和Module.php中有2个工厂。

如果我们在Module.php中制作

public function getControllerConfig() {
        return [
            'factories' => [
                Controller\IndexController::class => function($container) {
                    return new Controller\IndexController(
                        $container->get(Model\PlatnosciTable::class)
                    );
                },
            ],
        ];
    }

它不能在module.config.php中像

'controllers' => [
        'factories' => [
            Controller\IndexController::class => InvokableFactory::class,
        ],
    ],

因为它会覆盖。

ZF 3 __construct（）必须是......没有给出的实例
