Php laravel-更新一对多多态关系

我在一对多多态关系中有三个表

┌─────────────────┐          ┌─────────────────┐          ┌──────────────────┐
│ users           │          │ phones          │          │ departments      │
├─────────────────┤          ├─────────────────┤          ├──────────────────┤
| id              |          | id              |          | id               |
| name            |          | name            |          | name             |
└─────────────────┘          | phones_type     |          └──────────────────┘
                             | phones_id       |          
                             └─────────────────┘          

电话型号：

public function phones()
 {
   return $this->morphTo();
 }

用户模型：

public function phones()
 {
   return $this->morphMany('App\Phone', 'phones');
 }

部门模式：

public function phones()
 {
   return $this->morphMany('App\Phone', 'phones');
 }

现在我想更新电话号码，以便用户可以编辑/添加/删除号码。。我无法一步到位，所以我尝试先删除所有手机，然后添加新号码

我的代码： 部门总监：

public function update(UpdateDepartment $request, Department $department)
    {
        $department->phones()->delete();
        $department->name = $request['name'];
        $department->save();
        foreach ($request->phone as $value) {
            $phone = new Phone;
            $phone->name = $value;
            $ department->phones()->save($phone);
        }
    }

UpdateDepartment.php：

public function rules()
    {
        return [
            'name' => 'required|alpha_spaces|min:3|max:255|unique: department,name,'.$this-> department ->id,
            'phone'    => 'required|array|unique:phones,name,'
            'phone.*'  => 'required|distinct|unique:phones,name,',
        ];
    }

我有两个问题：

1-这样做对吗？有没有办法一步同步更新的电话号码

---

2-如果是这样的话。。。如果用户只是将电话号码添加到现有号码中，如何强制唯一规则忽略给定的ID？

1-您可以发送一些带有新电话号码的标识符（ID），这样您就可以知道修改的具体内容，例如放置一些

数据ID=“{{{$phone->ID}”

到电话字段，并使用javascript生成请求，以生成如下内容：

"phones":
  {
    "1"(your phone id):"+123456789",
    "2":"+123654978",
  }

public function update(UpdateDepartment $request, Department $department)
{
    $department->name = $request['name'];
    foreach ($request->phones as $id => $value) {
        $department->phones->transform(function($item) use ($id, $value){
            if($item->id == $id) {
                $item->name = $value;
                $item->save(); //if You using laravel 5 You need to savve each phone model separately
            }
        });
    }

    $department->push(); //if You using laravel 6.x, this will save model with all changed/created relations
}

然后像这样迭代请求数据：

"phones":
  {
    "1"(your phone id):"+123456789",
    "2":"+123654978",
  }

public function update(UpdateDepartment $request, Department $department)
{
    $department->name = $request['name'];
    foreach ($request->phones as $id => $value) {
        $department->phones->transform(function($item) use ($id, $value){
            if($item->id == $id) {
                $item->name = $value;
                $item->save(); //if You using laravel 5 You need to savve each phone model separately
            }
        });
    }

    $department->push(); //if You using laravel 6.x, this will save model with all changed/created relations
}

UPD 但我建议将电话号码作为

json

存储在用户和部门的单独字段中，这样就可以简单地将模型中的旧号码集替换为请求中的新号码集，而无需对数据库进行不必要的查询
