在 Laravel 6+ 中的 insert() 函数之后检索批量插入的 id

Question

我研究了很多，但找不到任何解决方案。所以我把它贴在这里 我的问题是在插入批量行后，我想获取所有插入的 ID 以将 ID 保存到另一个数据透视表。这是我的代码

$create_market = [];
                $create_market_possibility = [];
                foreach ($request->type0 as $key => $value) {
                    array_push($create_market, [
                        'market_id' => $value['market_id'],
                        'event_id' => $value['event_id'],
                        'name' => $value['name'],
                        'bet_min' => $value['min_bet'],
                        'bet_max' => $value['max_bet'],
                        'commission' => $value['commission'],
                        'type' => 0,
                        'created_at' => \Carbon\Carbon::now(),
                        'updated_at' => \Carbon\Carbon::now()
                    ]);
                }
                foreach ($request->type1 as $key => $value1) {
                    array_push($create_market, [
                        'market_id' => $value1['market_id'],
                        'event_id' => $value1['event_id'],
                        'name' => $value1['name'],
                        'bet_min' => $value1['min_bet'],
                        'bet_max' => $value1['max_bet'],
                        'commission' => $value1['commission'],
                        'type' => 1,
                        'created_at' => \Carbon\Carbon::now(),
                        'updated_at' => \Carbon\Carbon::now()
                    ]);
                    foreach ($value1['possibility'] as $key => $value2) {
                        array_push($create_market_possibility, [

                            // because i am not getting the inserted ids here i cant push it here
                            // that is the problem i am facing 

                            'market_id' => $value1['market_id'],
                            'event_id' => $value1['event_id'],
                            'possibility' => $value2['possibility'],
                            'created_at' => \Carbon\Carbon::now(),
                            'updated_at' => \Carbon\Carbon::now()
                        ]);
                    }
                }
                Market::insert($create_market);
                // Here i want to retrive the last inserted all ids and put then in the obj of
                  [$create_market_possibility] array ... 

                if(count($create_market_possibility) > 0) {
                    MarketPossibility::insert($create_market_possibility);
                }
                $response = [
                    'status' => true,
                    'message' => 'Market Successfully Created'
                ];
                return response()->json($response); //@ sending response

我在使用 create() 进行单次插入时做了这件事 $id = Market::create($array) 它返回了我的对象.. 但在这种情况下，我必须插入多行..
如果有其他方法请告诉我，谢谢！

Answer 1

1。对于 type0

您可以为 type0 运行 Market::insert($array)，因为没有关联的 MarketPossibility

2。对于 type1，

您必须一个一个地创建每个市场，然后将其关联 - 您可以使用 saveMany() 使其更干净更快：

$market = Market::create([...])

$new_market_possibility = [];
foreach ($value1['possibility'] as $key => $value2) {
    $new_market_possibility[] = new App\MarketPossibility([...]);
}

$market->marketPossibilities()->saveMany($new_market_possibilities);

假设您在 Market 和 MarketPossibility 之间建立了标准关系
