Question

我是symfony的新手，我正在尝试将结果数组显示到twig模板中。这是问题..

这是我的实体

<?php

namespace XYZ\FirstBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Shifts
 * @ORM\Entity(repositoryClass="XYZ\FirstBundle\Repository\ShiftRepository")
 * @ORM\Table(name="shifts")
 */
class Shifts
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var \DateTime
     *
     * @ORM\Column(name="date", type="date")
     */
    private $date;

    /**
     * @var string
     *
     * @ORM\Column(name="site_name", type="string", length=255)
     */
    private $site_name;

    /**
     * @var string
     *
     * @ORM\Column(name="location", type="string", length=255)
     */
    private $location;

    /**
     * @var \DateTime
     *
     * @ORM\Column(name="start_time", type="time")
     */
    private $startTime;

    /**
     * @var \DateTime
     *
     * @ORM\Column(name="end_time", type="time")
     */
    private $endTime;


    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }

    /**
     * Set date
     *
     * @param \DateTime $date
     * @return Shifts
     */
    public function setDate($date)
    {
        $this->date = $date;

        return $this;
    }

    /**
     * Get date
     *
     * @return \DateTime 
     */
    public function getDate()
    {
        return $this->date;
    }

    /**
     * Set site_name
     *
     * @param string $location
     * @return Shifts
     */
    public function setSitename($site_name)
    {
        $this->site_name = $site_name;

        return $this;
    }

    /**
     * Get site_name
     *
     * @return string 
     */
    public function getSitename()
    {
        return $this->site_name;
    }

    /**
     * Set location
     *
     * @param string $location
     * @return Shifts
     */
    public function setLocation($location)
    {
        $this->location = $location;

        return $this;
    }

    /**
     * Get location
     *
     * @return string 
     */
    public function getLocation()
    {
        return $this->location;
    }

    /**
     * Set startTime
     *
     * @param \DateTime $startTime
     * @return Shifts
     */
    public function setStartTime($startTime)
    {
        $this->startTime = $startTime;

        return $this;
    }

    /**
     * Get startTime
     *
     * @return \DateTime 
     */
    public function getStartTime()
    {
        return $this->startTime;
    }

    /**
     * Set endTime
     *
     * @param \DateTime $endTime
     * @return Shifts
     */
    public function setEndTime($endTime)
    {
        $this->endTime = $endTime;

        return $this;
    }

    /**
     * Get endTime
     *
     * @return \DateTime 
     */
    public function getEndTime()
    {
        return $this->endTime;
    }

    /**
     *
     * @return string String representation of this class
     */
    public function __toString()
    {

        return (string) $this->site_name;
        return (string) $this->location;
        return (string) $this->startTime;
        return (string) $this->endTime;


    }
}

控制器

 public function showShiftAction() 
    {
        $em = $this->getDoctrine()->getManager();
        $shift =array();
        $shift = $em->getRepository('XYZFirstBundle:Shifts')
         ->findAll();

         var_dump($shift);

        return $this->render('XYZFirstBundle:Default:allshifts.html.twig', array(
                'shift' => $shift
            ));
    }

存储库

<?php

namespace XYZ\FirstBundle\Repository;

use Doctrine\ORM\EntityRepository;

class ShiftRepository extends EntityRepository
{
    public function showAllShifts()
    {
        return $this->getEntityManager()
            ->createQuery (
                'SELECT Shifts FROM XYZFirstBundle:Shifts Shifts'
                )
            ->getResult();
    }
}

现在我在模板中使用以下内容..

{% extends 'base.html.twig' %}

{% block title %}RMS-Roster{% endblock %}


 {% block pageContent %}

    <h2>Create Roster</h2>   
                        <h5>These are all your shifts</h5> <br>
                        {{ shift.date }}
                        {{ shift.site_name }}
                        {{ shift.location }}
                        {{ shift.startTime }}
                        {{ shift.endTime }}

 {% endblock %}

我收到此错误 - ATTERACFirstBundle中不存在具有键“0,1,2,3”的数组的键“日期”：默认：第10行的allshifts.html.twig

但在var_dump()我正在获取整个数组。当我使用这个

{% block pageContent %}

    <h2>Create Roster</h2>   
                        <h5>These are all your shifts</h5> <br>
                        {{ shift.0 }}
                        {{ shift.1 }}
                        {{ shift.2 }}
                        {{ shift.3 }}

 {% endblock %}

我获得了唯一的site_name结果。

我不确定我哪里出错了。期待见解。提前致谢。干杯
