无法使用symfony和主义及其关联对象或表保存到postgresql中？

Question

I have to save a ticket with ticket_attachments , ticket_comments and ticket_status_history . I will persist only ticket object but want to save attachments,comments and history. I am using doctrine and symfony and annotations.

I have created 3 array collections in ticket with mappedBy and cascade remove and persist. And used inversedBy in attachments, comments and history. But after persisting and flush only ticket is being saved but other objects ie attachments,comments and historys are not saving. But shows No Error .

Ticket.php

/**
     * @ORM\OneToMany(targetEntity="AppBundle\Entity\TicketAttachments", mappedBy="ticket", cascade={"persist", "remove"})
     */
    private $attachments;

    /**
     * @ORM\OneToMany(targetEntity="AppBundle\Entity\TicketComments", mappedBy="ticket", cascade={"persist", "remove"})
     */
    private $comments;

    /**
     * @ORM\OneToMany(targetEntity="AppBundle\Entity\TicketStatusHistory", mappedBy="ticket", cascade={"persist", "remove"})
     */
    private $historys;

    public function __construct()
    {
        $this->attachments = new ArrayCollection();
        $this->comments = new ArrayCollection();
        $this->historys = new ArrayCollection();
    }

History, Comments and Attachments.php

/**
     * @var \AppBundle\Entity\Ticket
     *
     * @ORM\ManyToOne(targetEntity="AppBundle\Entity\Ticket", inversedBy="historys")
     * @ORM\JoinColumns({
     *   @ORM\JoinColumn(name="ticket_id", referencedColumnName="id")
     * })
     */
    private $ticket;

All have it's setter and getter. Where is the problem?

Answer 1

Are you setting them to each other? As in:

public function addToHistories($history) {
   $this->historys[] = $history;
   $history->setTicket($this);
}

They have to be associated with each other within the setters (or some other way) for cascade persist to work.
