解决Go gorm踩过的坑

Scan error on column index 1, name “created_at”

提示：

Scan error on column index 1, name “created_at”: unsupported Scan, storing driver.Value type []uint8

打开数据库的时候加上parseTime=true

root:123456@tcp(127.0.0.1:3306)/mapdb?charset=utf8&parseTime=true

补充：golang Gorm 的使用总结

func (CoinLog) TableName() string {
 return "coin_log"
}

ID            int64              `gorm:"column:id" JSON:"id"`

通过预加载可以实现各个模型之间的一对多关系，例如下面的代码，其中device结构体对应多个DeviceModular，DeviceModular又有多个CommWeimaqi

db.sqlDB.Preload("DeviceModular", "modular_type=1").Preload("DeviceModular.CommWeimaqi").Find(&device)

gorm暂时不支持批量插入

  tx := db.SqlDB.Begin()
  sqlStr := "INSERT INTO report_form (id,create_time,choose_count, device_fall_count,game_order_count,coin_count,member_count," +
   "day_member_count,visit_count,lgz_coin_count,weimaqi_coin_count,store_id,real_coin_count,m_coin_count,coin_spec) VALUES "
  vals := []interface{}{}
  const rowSQL = "(?,?, ?, ?, ?, ?, ?, ?, ?, ?,?,?,?,?,?)"
  var inserts []string
  for _, elem := range reportForms {
   inserts = append(inserts, rowSQL)
   vals = append(vals, elem.ID, elem.CreateTime, elem.ChooseCount, elem.DeviceFallCount, elem.GameOrderCount, elem.CoinCount, elem.MemberCount, elem.DayMemberCount, elem.VisitCount, elem.LgzCoinCount, elem.WeimaqiCoinCount, elem.StoreId, elem.RealCoinCount, elem.MCoinCount, elem.CoinSpec)
  }
  sqlStr = sqlStr + strings.Join(inserts, ",")
  err := tx.Exec(sqlStr, vals...).Error
  if  err != nil {
   tx.Rollback()
   fmt.Print(err)
  }else {
   tx.Commit()
  }

以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。如有错误或未考虑完全的地方，望不吝赐教。
