php - laravel 5.5-尝试获取非对象的属性时出错(views\pledges\index.blade.php)

我得到了非对象错误的属性
竞选、宣誓和会员模式相互关联，也就是说他们之间的关系是自相矛盾的。
这是我的竞选模式

   class Campaign extends Model
{
    protected $table = "campaigns";

    public function pledges()
    {
        return $this->hasMany(Pledge::class, 'campaign_id', 'id')->orderBy('created_at', 'desc');
    }
}

这是我的保证模型

   class Pledge extends Model
{
    protected $table = "pledges";

    public function campaign()
    {
        return $this->hasOne(Campaign::class, 'id', 'campaign_id');
    }


    public function member()
    {
        return $this->hasOne(Member::class, 'id', 'member_id');
    }
}

这是我的会员模型

   class Member extends Model
{
    protected $table = "members";

    public function loans()
    {
        return $this->hasMany(Loan::class, 'borrower_id', 'id');
    }

    public function user()
    {
        return $this->hasOne(User::class, 'id', 'user_id');
    }

    public function pledges()
    {
        return $this->hasMany(Pledge::class, 'member_id', 'id');
    }

    public function contributions()
    {
        return $this->hasMany(Contribution::class, 'member_id', 'id');
    }

    public function tags()
    {
        return $this->hasMany(MemberTag::class, 'member_id', 'id');
    }

    public function attendance()
    {
        return $this->hasMany(EventAttendance::class, 'member_id', 'id');
    }
    public function families()
    {
        return $this->hasMany(FamilyMember::class, 'member_id', 'id');
    }
    public function family()
    {
        return $this->hasOne(Family::class, 'member_id', 'id');
    }
}

这是我的view.pleedge.blade文件我不知道为什么会得到试图得到非对象错误，你的输入将非常感谢各位。

<div class="widget-content nopadding">
            <table class="table table-bordered data-table">
              <thead>
                <tr>
                  <th>Campaign</th>
                  <th>Member</th>
                  <th>Amount</th>
                  <th>Date</th>
                </tr>
              </thead>
              <tbody>


                <tr class="gradeX">


                    @foreach ($pledge as $pledges)
                      <td>{{ $pledges->member->first_name }}</td>
                       <td>{{ $pledges->campaign->campaign_id }}</td>
                        <td>{{ $pledges->pledges->amount }}</td>
                        <td>{{ $pledges->pledges->date }}</td>
                    @endforeach
                </tr>
              </tbody>
            </table>

嘿，伙计们，这是保证控制器，便于调试。非常感谢到目前为止的反馈。

<?php

class Pledgecontroller extends Controller

    /**

     * @return \Illuminate\Http\Response
     */
    public function index()
    {

        $member= Member::all();
        $campaign= Campaign::all();
        $pledge= Pledge::all();
        return view ('pledges.index', compact ('member', 'campaign', 'pledge'));

最佳答案

你应该使用正确的关系：

class Pledge extends Model
{
    protected $table = "pledges";

    public function campaign()
    {
        return $this->belongsTo(Campaign::class, 'campaign_id');
    }


    public function member()
    {
        return $this->belongsTo(Member::class, 'member_id');
    }
}

另外，你不应该这样做，因为你没有承诺有承诺：

$pledges->pledges->amount

此外，如果不是所有的保证都属于某个成员，则需要检查以下内容：

optional($pledges->member)->first_name
