Question

withTrashed怎样才能应用hasManyThrough关系？

$this->hasManyThrough('App\Message', 'App\Deal')->withTrashed();

返回

调用未定义的方法Illuminate \ Database \ Query \ Builder :: withTrashed（）

当我做的时候：

$messages = Auth::user()->messages()->with('deal')->orderBy('created_at', 'DESC')->get();`

这是我的交易模型：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;

class Deal extends Model
{

    use SoftDeletes;

    /* ... */

    protected $dates = ['deleted_at'];

    public function user() {
        return $this->belongsTo('App\User');
    }

    public function messages() {
        return $this->hasMany('App\Message'); // I've tried to put withTrashed() here, there is no error but it doesn't include soft deleting items.
    }
}

Answer 1

对于所有来迟的人，现在有一种使用Laravel进行此操作的本地方法。

$this->hasManyThrough('App\Message', 'App\Deal')->withTrashedParents();

此文档记录不充分，但可以在Illuminate\Database\Eloquent\Relations\HasManyThrough

中找到

Answer 2

引发错误是因为您在SoftDelete模型中未使用Message特征而请求已删除邮件的邮件。

在检查hasManyThrough关系代码后，我发现没有办法以这种方式进行，你应该玩。

例如：

使用消息获取用户的交易

$deals = Auth::user()->deals()->withTrashed()->with('messages')->get();
foreach($deals as $deal) {
     //Do your logic here and you can access messages of deal with $deal->messages
}
