Symfony：如何获取与oneToMany关系相关的所有用户帖子

Question

我有两个实体User和Booking，它们与oneToMany关系相关，当用户进行预订时，用户ID保存在预订的user_id列表中，我希望在控制器中检索所有用户的预订！ >

/**
 * @ORM\ManyToOne(targetEntity=User::class, inversedBy="bookings")
 * @JoinColumn(name="user_id", referencedColumnName="id")
 */
private $user;

    public function setUser(?User $user): self
    {
        $this->user = $user;

        return $this;
    }

---

/**
     * @ORM\OneToMany(targetEntity=Booking::class, mappedBy="user")
     */
    private $bookings;

/**
     * @return Collection|Booking[]
     */
    public function getBookings(): Collection
    {
        return $this->bookings;
    }

    public function addBooking(Booking $booking): self
    {
        if (!$this->bookings->contains($booking)) {
            $this->bookings[] = $booking;
            $booking->setUser($this);
        }

        return $this;
    }

---

/**
     * @Route("/user/profile/my-bookings", name="user.profile.bookings")
     */

    public function getUserBookings(){
        $user = $this->getUser()->getBookings();

        return $this->render('user/user.bookings.html.twig', [
            'user'=>$user
        ]);
    }

当尝试获取连接的用户并调用getBookings（）方法时，它不会返回任何东西！

$ this-> getUser返回什么：

Answer 1

您可以使用

从树枝上打印它

{% for booking in user.bookings %}
    {{booking}}
{% endfor %}

或使用PHP将其检索到您的控制器中

foreach($user->getBookings() as $booking){
    echo $booking->getYourField();
}

Answer 2

我找到了解决方案，我只是忘了在用户和预订之间的OneToMany关系中添加获取EAGER了！
