我有两个模型,User
和 Team
它们之间的关系是ManyToMany
:
在用户
中:
public function teamMembers(){
return $this->belongsToMany('App\Team')->withPivot('id');;
}
在 Team
中:
public function teamMembers(){
return $this->belongsToMany('App\User')->withPivot('id');;
}
现在我想将用户添加到特定团队。所以数据透视表名称是 team_user
。
现在我要插入数据透视表的数据是:
array:4 [▼
"_token" => "mlwoAgCQYals1N1s2lNa4U5OTgtMNHh9LUhNGrWh"
"team_id" => "1"
"members_id" => array:3 [▼
0 => "2"
1 => "3"
2 => "4"
]
"status" => "1"
]
我在我的 Controller 中做了什么:
$team_id = $request->get("team_id");
$team = \App\Team::findOrFail($team_id);
foreach ($request->get('members_id') as $key => $value) {
$team->teamMembers()->attach($team);
$team->save();
}
但它只插入一条记录,我的意思是team_id
和第一个member_id
。
我希望它从 members_id
数组中为每个成员创建一条记录。我该怎么做?
最佳答案
您应该将一组用户 ID 传递给 attach()
方法。
For convenience,
attach
anddetach
also accept arrays of IDs as input
将您的代码更改为:
$team = \App\Team::findOrFail($request->team_id);
$team->teamMembers()->attach($request->members_id);
