Question

我正在制作一项功能，每当我向RMA票证添加评论时，它都会向用户发送电子邮件，但我在提交评论时收到Trying to get property of non-object

下面我粘贴了CommentController和Email函数中的代码如果你想了解更多信息，我会发布我可以发布的信息

我收到此代码的错误 - $mailer->sendRmaTicketComments($comment->ticket->user, Auth::user(), $comment->ticket, $comment);

CommentController代码

<?php

namespace App\Http\Controllers\Rma;

use Auth;
use App\User;

use App\Rma\RmaTicket;
use App\Rma\RmaComments;

use App\Mailers\AppMailer;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class RmaCommentController extends Controller
{
    public function postComment(Request $request, AppMailer $mailer)
    {
        $this->validate($request, [
           'comment'    => 'required',
           'user_id'    => 'required',
        ]);

        $comment = RmaComments::create([
           'rma_ticket_id'  => $request->input('ticket_id'),
           'user_id'    => $request->input('user_id'),
           'comment'    => $request->input('comment'),
        ]);

        $mailer->sendRmaTicketComments($comment->ticket->user, Auth::user(), $comment->ticket, $comment);

        return redirect()->back()->with('successPanel', 'Thank you for your message please allow up to 48 hours for a response.');
    }
}

邮件功能代码

<?php

namespace App\Mailers;

use App\Rma\RmaTicket;
use App\Rma\RmaStatus;

use App\SupportTickets\SupportTicket;
use App\SupportTickets\SupportTicketStatus;

use App\User;
use Illuminate\Contracts\Mail\Mailer;
use Illuminate\Support\Facades\Mail;

class AppMailer
{
    protected $mailer;

    /**
     * Get the email address
     *
     * @var [type]
     */
    protected $to;

    /**
     * Set the subject for the email
     *
     * @var [type]
     */
    protected $subject;

    /**
     * Set the template for the email
     *
     * @var [type]
     */
    protected $view;

    /**
     * Set the data for the email
     *
     * @var array
     */
    protected $data = [];

    public function __construct(Mailer $mailer)
    {
        $this->mailer = $mailer;
    }

/**
     * Send RMA Comments/Replies to RMA Owner
     *
     * @param User      $ticketOwner
     * @param User      $user
     * @param rmaTicket $rmaTicket
     * @param Comment   $comment
     *
     * @return method delivered()
     */
    public function sendRmaTicketComments($ticketOwner, $user, RmaTicket $rmaTicket, $comment)
    {
        $this->to      = $ticketOwner->email;
        $this->subject = "RE[RMA Ticket # $rmaTicket->rma_ticket_id]";
        $this->view    = 'emails.rma.rma_comments';
        $this->data    = compact('ticketOwner', 'user', 'rmaTicket', 'comment');

        return $this->deliver();
    }

RmaComments模型

<?php

namespace App\Rma;

use Illuminate\Database\Eloquent\Model;

class RmaComments extends Model
{
    protected $table = 'rma_comments';
    protected $fillable = [
        'rma_ticket_id', 'user_id', 'comment'
    ];

    public function ticket()
    {
        return $this->belongsTo(RmaTicket::class);
    }

    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

RMA模型

<?php

namespace App\Rma;

use Illuminate\Database\Eloquent\Model;

class RmaTicket extends Model
{
    protected $table = 'rma_tickets';
    protected $fillable = [
        'user_id', 'rma_ticket_id', 'first_name', 'last_name',
        'email', 'fax', 'company', 'marketplace_id', 'returnTypeId',
        'product_name', 'quantity', 'order_number', 'address_one',

        'status_id', 'rma_number', 'refund_number', 'return_tracking_number',
        'replacement_number', 'return_label'
    ];

    public function returnType()
    {
        return $this->belongsTo(RmaReturnType::class);
    }

    public function marketplace()
    {
        return $this->belongsTo(RmaMarketplace::class);
    }

    public function status()
    {
        return $this->belongsTo(RmaStatus::class);
    }


     public function comments()
    {
        return $this->hasMany(RmaComments::class);
    }


    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

查看你的代码，如果你有dd（$ comment-＆gt; ticket）你就知道了，我相信这是你外键的命名。

your belongsTo：

deactivate
./bin/sshuttle mysshuser@mysshserver

需要ticket_id，但您将其命名为rma_ticket_id。

您可以在belongsTo关系中的第二个参数中指定不同的外键名称

 public function ticket()
{
    return $this->belongsTo(RmaTicket::class);
}

根据文档：

。 Eloquent通过检查关系方法的名称并使用_id为方法名称添加后缀来确定默认外键名称。但是，如果Phone模型上的外键不是user_id，则可以将自定义键名作为第二个参数传递给belongsTo方法：
