使用与雄辩的关系 [英] Using withTrashed with relationships in Eloquent

问题描述

有没有办法使用 withTrashed 与Eloquent中的关系。

Is there a way to use withTrashed with relationships in Eloquent.

我需要的是这个。我有表和模型标记和另一个表用户。 用户有许多标记和标记属于用户。所以我在Eloquent模型中定义了这一点。

What I need is this. I have table and model Mark and another table User. User has many Mark and Mark belongs to User. So I defined this in Eloquent models.

现在我需要得到一个软删除的 Mark 的实例。如果用户不被软删除，但如果标记和用户软删除，我收到错误尝试获取非对象的属性，因为

Now I need to get an instance of Mark that is soft deleted. This is not a problem if User isn't soft deleted, but if both Mark and User are soft deleted, I get an error Trying to get property of non-object, because

$mark->user

t返回实际用户，因为它是软删除。

won't return actual user, cause it is soft deleted.

有没有办法，我可以做一些像

Is there a way that I can do something like

$mark->withTrashed()->user

得到这个相关的用户，即使它被删除了

to get this related user even if it is deleted?

推荐答案

根据你的需要，你可以定义关系： p>

Depenging on your needs, you can define the relationship:

public function marks()
{
  return $this->hasMany('Mark')->withTrashed();
}

// then just
$user->marks;

或即时使用：

$user->marks()->withTrashed()->get();

// or when lazy/eager loading
$user = User::with(['marks' => function ($q) {
   $q->withTrashed();
}])->find($userId);

在您粘贴的示例中，将是：

And in your pasted example it will be:

$mark->user() // get relation object first
   ->withTrashed() // apply withTrashed on the relation query
   ->first();  // fetch the user

// alternatively you use getResults relation method
$mark->user()
   ->withTrashed()
   ->getResults();  // returns single model for belongsTo

$user->marks()->withTrashed()
   ->getResults(); // returns collection for hasMany
