我有一个这样的父表:
俱乐部
ID | 姓名 | 预算 |
---|---|---|
1 | 兵工厂 | 90 |
2 | 切尔西 | 150 |
3 | 曼城 | 135 |
4 | 曼联 | 140 |
5 | 托特纳姆热刺 | 87 |
还有这样的子表
球员
ID | club_id | 姓名 | 位置 |
---|---|---|---|
1 | 3 | 希腊语 | LM |
2 | 3 | 英镑 | 长宽 |
3 | 3 | 哈兰德 | 英石 |
4 | 1 | 迪巴拉 | 英石 |
5 | 1 | 卡塞米罗 | DM |
6 | 4 | 弗雷德 | DM |
7 | 2 | 姆巴佩 | 英石 |
8 | 2 | 冒险 | 长宽 |
9 | 4 | 瓦拉内 | DM |
club_id 是引用 clubs 表 id 列的外键
俱乐部模式
public function players()
{
return $this->hasMany('App\Models\Player', 'club_id', 'id');
}
播放器模型
public function club()
{
return $this->belongsTo('App\Models\Club', 'club_id', 'id');
}
我有一个数组输入和逻辑来创建这样的俱乐部和球员:
// the array create input will contain the club and all the players that is related to the club
$createInput = array(
'title' => 'Liverpool',
'budget' => '70'
'players' => [
[
'name' => 'Handerson',
'Position' => 'CM'
],
[
'name' => 'Milner',
'Position' => 'LW'
]
]
);
$club = new Club;
$club->name = $createInput['name];
$club->budget = $createInput['name];
$club->save();
foreach($createInput['players'] as $playerInput){
$player = new Player;
$player->name = $playerInput['name'];
$player->position = $playerInput['position'];
$player->save();
}]
我有一个数组输入和逻辑来更新俱乐部和球员,如下所示:
// the array update input will contain the club and all the players that are related to the club
$updateInput = array(
'id'. => 1,
'budget' => '50',
'players' => [
[
'id' => '4',
'name' => 'Dybala',
'Position' => 'ST'
],
[
'name' => 'Sane',
'Position' => 'LW'
],
[
'name' => 'De Ligt',
'Position' => 'DF'
]
]
);
$club = Club::find($updateInput['id']);
if(isset($updateInput['name'])) $club->name = $updateInput['name'];
if(isset($updateInput['budget'])) $club->budget = $updateInput['budget'];
$club->save();
$existingIds = [];
foreach($updateInput['players'] as $playerInput){
if(isset($playerInput['id'])) $player = Player::find($playerInput['id']);
else $player = new Player;
if(isset($updateInput['name'])) $player->name = $playerInput['name'];
if(isset($updateInput['position'])) $player->name = $playerInput['position'];
$player->save();
$existingIds[] = $player->id;
}
//if the player id is not in the input data then delete it
DB::table('players')->whereNotIn('id', $existingIds)->where('club_id', $club->id)->delete();
我打算通过使用 sync 和 createorupdate 方法来简化我的代码,但我不确定哪个更适合插入/更新/删除连接到俱乐部表的相关球员数据?
