我正在使用 Doctrine ORM。
尝试从数据库中获取数据时出现此错误：
Fatal error: Uncaught PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'db.GenericMeasurements' doesn't exist

生成错误的代码：

$sensor = $entityManager->getRepository('EspRemoteServer\Entity\GenericSensor')->getSensor(1);
    foreach ($sensor as $s)
    {
        $measurement = $s->getMeasurements();
        $values = $measurement->getValues();
    }

它进入 getValues() 并在尝试执行 sql 时生成错误。我试图用 AssociationOverride 做一些事情，但似乎我无法覆盖表名。

通用测量.php

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\MappedSuperclass
 */
abstract class GenericMeasurements
{
    /**
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     * @ORM\Column(name="id", type="integer")
     */
    private $id;

    /**
     * @ORM\Column(name="time", type="datetime", nullable=false)
     */
    private $time;

    /**
    * @ORM\ManyToOne(targetEntity="GenericSensor", inversedBy="measurements")
    * @ORM\JoinColumn(name="sensor_id", referencedColumnName="id")
    */
    private $sensor;

    function __construct()
    {
    }

    //getters and setters
}

DS18B20Measurements.php

/**
 * @ORM\Entity
 * @ORM\Table(name="ds18b20_sensor")
*/
class DS18B20Measurements extends GenericMeasurements
{
    use TemperatureTrait;

    function __construct()
    {
    }
}

通用传感器.php

/**

class GenericSensor
{
    /**

    private $id;

    /**

    private $name;

    private $token;

    private $description;
    
    /**

    */
    private $location;

    /**
    * @ORM\OneToMany(targetEntity="GenericMeasurements", mappedBy="sensor")
    **/
    private $measurements;


    function __construct($name = '', $token = '', $description = '', $location = '')
    {
        $this->name = $name;
        $this->token = $token;
        $this->description = $description;
        $this->location = $location;
        $this->measurements = new ArrayCollection();
    }

    //getters and setters
}
