蒸气3 Fluent MySQL:在模型上保存可为auto_increment添加10倍

当我将对象保存到数据库中时,它会将对象的ID存储为+10。默认情况下,表的自动增量为1。当我向数据库中手动添加内容时,它的增量为1。

我是否缺少FluentMySQL的设置(或我的错误设置)?

  func storeOrUpdateItemRecord(_ item: FetcherItem, store: Store, on conn: DatabaseConnectable) throws -> EventLoopFuture<Item> {
    guard let storeId = store.id else {
      throw Abort(.internalServerError)
    }

    let calendar = Calendar.current
    let fromDate = calendar.startOfDay(for: Date())
    guard let endDate = calendar.date(bySettingHour: 23, minute: 59, second: 59, of: Date()) else { throw Abort(.internalServerError) }

    return Item.query(on: conn)
      // Bunch of filters
      .filter(\.scheduledDate < endDate)
      .all()
      .flatMap(to: Flight.self) { flights in
        if var firstItem = flights.first {
          debugPrint("Found item, updating...")
          // Update a bunch of values
          return firstItem.save(on: conn)
        }

        debugPrint("Did not find item, saving new...")
        return item.toItem(forStore: store).save(on: conn)
    }
  }

toItem函数不执行任何操作,然后启动新的Item

extension FetcherItem {

  func toItem(forStore store: Store) -> Item {
    return Item.init(
      id: nil,
      // Set a bunch of values
      actualDate: actualDateTime)
  }
}

如您所见,id设置为nil ...我猜应该在进行插入查询时使用null存储。

数据库中的结果

MySQL db result

我想念什么?

更新: 在遵循this page的建议之后,我为查询添加了日志记录...,它们似乎可以正常工作。 流利的查询示例:

[mysql] [2019-03-06 08:49:44 +0000] INSERT INTO `Items` (`company`, `name`, `storeId`, [...] `scheduledDate`) VALUES (?, ?, ?, ?, ?, ?, ?, ?) [string("A company"), string("abc123"), integer8(1), [...] time(2019-3-6 16:25:0.0)]

如您所见,它不会以任何方式设置id。也许是MySQL问题?

答案 0 :(得分:1)

Found the problem. MySQL has set the @@auto_increment_increment to 10, hence the jumping.

More information here:

If you have this problem, run the following command (source):

  • SELECT @@auto_increment_increment

and to set it:

  • SET @@auto_increment_increment=1
