為什么我的 updateOrInsert 不起作用 laravel

Question

我使用 updateOrInsert 來避免重復數據，為什么 Update 函數不起作用並且總是插入數據？

foreach($datas as $data){
                    DB::table('users')->updateOrInsert([
                        'user_connect_id' => $user->connect_id,
                        'description' => $data['description'],
                        'created_by' => $login->name,
                        'modified_by' => $login->name,
                        'created_at' => Carbon::now(),
                    ]);
                }

Answer 1

看看這個updateOrInsert ，你需要兩個參數，一個是匹配的屬性，另一個是你的數組。

updateOrInsert(array $attributes, array $values = []) 

例子：

DB::table('users')->updateOrInsert(['user_connect_id' => $user->connect_id],
                     [
                        'user_connect_id' => $user->connect_id,
                        'description' => $data['description'],
                        'created_by' => $login->name,
                        'modified_by' => $login->name,
                        'created_at' => Carbon::now(),
                     ]);

Answer 2

updateOrInsert 方法中有兩個參數。updateOrInsert 方法接受兩個參數：查找記錄的條件數組，以及包含要更新的列的列和值對數組。

例如：

DB::table('users')
    ->updateOrInsert(
        ['email' => 'john@example.com', 'name' => 'John'],
        ['votes' => '2']
    );
