Question

我有组和组成员，一个表用于组，其中我只存储组名，第二个表是组成员，其中我有user_id，group_id字段。

我正在使用邮递员创建API，我想插入小组成员的详细信息，如下所示：

"group_members": [1,3]

我的身体要求是：

{
    "name": "Steve", // name is group name
    "group_members": [1,3]  // [1,3] here 1 and 3 is user_id
}

我要针对[group_id]将[1,3]存储到user_id字段的group_members表中，如果存在[1,3]，则应在user_id字段中输入两个条目我还附上了桌子的屏幕截图：

我的控制器：

DB::beginTransaction();

    try{

        $request->request->add(['created_by' => Auth::user()->id]);
        $group = $this->group->create($request->only($this->group->getModel()->fillable));
        $request->request->add(['group_id' => $group->id]);
        $this->groupMembers->create($request->only($this->groupMembers->getModel()->fillable));

        DB::commit();

        return response([
            'status' => true,
            'message' => 'Group added',

        ], 200);

    } catch(\Exception $ex) {
        DB::rollback();
        return response([
            'status' => false,
            'message' => __('messages.validation_errors'),
            'errors' => $ex->getMessage(),
        ], 500);
    }

我如何将这个数组值存储到数据库中，您的帮助将不胜感激？https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.security/set-executionpolicy?view=powershell-6

               try {

        $group = $this->group->find($request->input('id'));
        $request->request->add(['updated_by' => Auth::user()->id]);
        $group->fill($request->all())->save();

        return response(['status' => true, 'message' => 'Group updated'], 500);

    } catch (\Exception $ex) {
        return response(['status' => false, 'message' => 'Validation Errors', 'errors' => $ex->getMessage()], 500);
    }





      public function updateGroup(Request $request)
    {
    $validator = UserValidations::validateGroup($request->all());

    if($validator->fails()) {
        return response(['status' => false, 'message' => 'Validation Errors', 'errors' => $validator->errors()->all()], 500);
    }

    try {

        $group = $this->group->find($request->input('id'));
        $request->request->add(['updated_by' => Auth::user()->id]);
        $group->fill($request->all())->save();

        return response(['status' => true, 'message' => 'Group updated'], 500);

    } catch (\Exception $ex) {
        return response(['status' => false, 'message' => 'Validation Errors', 'errors' => $ex->getMessage()], 500);
    }
}

Answer 1

更改这两行

$request->request->add(['group_id' => $group->id]);
$this->groupMembers->create($request->only($this->groupMembers->getModel()->fillable));

收件人

$user_ids = $request->get('group_members');
foreach($user_ids as $user_id){
    $this->groupMembers->create(['group_id' => $group->id, 'user_id'=>$user_id]);
}

希望这可以解决您的问题。

使用attach和many to many关系来做。

Group.php

User.php

let urls  = URL(string: "itms-apps://itunes.apple.com/in/app/brother-iprint-label/id523047493?mt=8")
    if UIApplication.shared.canOpenURL(urls!) {
        UIApplication.shared.open(urls!, options: [:], completionHandler: nil)
    }

现在，您只需执行以下操作即可按其ID将成员添加到组中：

class Group extends Model
{
    public function users()
    {
        return $this->belongsToMany('App\User', 'group_members');
    }
}

如果您要从组中删除一个或多个成员，则同样如此：

class User extends Model
{
    public function groups()
    {
        return $this->belongsToMany('App\Group', 'group_members');
    }
}
