Laravel

Question

我想根据条件从模型中分离值。我想从类型为 3 的组织中分离所有人员，即工人。但是当我尝试这样做时，它分离了所有人，没有考虑 where 条件。

这是我的关系：

Class：组织

public function people()
{
    return $this->belongsToMany(People::class, 'organization_people')
}

public function workers()
{
    return $this->people()->where('type', 3); //returns all workers
}

public function detachWorkers()
{
    $this->workers()->detach(); // this detaches all people, I want it to detach only workers
}

Answer 1

您需要这样做：

public function people()
{
    return $this->belongsToMany(People::class, 'organization_people')
}

public function workers()
{
    return $this->people()->where('type', 3);
}

public function detachWorkers()
{
    $this->people()->detach($this->workers); 
}

IIUC Laravel 不会将 where 约束附加到 detach 上。但是，它将直接附加您放置在枢轴 table 上的任何约束，例如 $this->people()->wherePivot('type', 3); 假设您在枢轴 table.[=15 上有一个 type 列=]
