英文:
Golang with GORM - sqlite Error when trying to migrate
问题
我正在开发一个机器人。为此，我决定使用sqlite数据库和GORM作为ORM。现在我正在处理一个简单的"Connection"文件，它应该连接到sqlite数据库（与Conection.go文件位于同一文件夹中）并迁移预定义的结构。
package database
import (
_ "github.com/mattn/go-sqlite3"
GlobalModels "goBot/modules/global/models"
"gorm.io/driver/sqlite"
"gorm.io/gorm"
"log"
"os"
)
func Connect() *gorm.DB {
log.Print(os.Getenv("DB_PATH"))
db, err := gorm.Open(sqlite.Open("db.sqlite"), &gorm.Config{})
if err != nil {
log.Fatal(err)
}
return db
}
func Migrate() {
db := Connect()
errUser := db.AutoMigrate(GlobalModels.User{})
if errUser != nil {
log.Fatal(errUser)
}
errUserFlags := db.AutoMigrate(GlobalModels.UserFlags{})
if errUserFlags != nil {
log.Fatal(errUserFlags)
}
}
以下是预定义的结构User.go和UserFlags.go：
package models
import "gorm.io/gorm"
type User struct {
gorm.Model
Name string `gorm:"column:name"`
UserID int `gorm:"column:user_id"`
ChatID string `gorm:"column:chat_id"`
}
package models
import "gorm.io/gorm"
type UserFlags struct {
gorm.Model
UserID int
LastModuleChosen string `gorm:"column:last_module_chosen"`
User User `gorm:"foreignKey:UserID"`
}
这是主函数，我在其中尝试迁移这些模型：
func main() {
database.Migrate()
fmt.Println("Starting the bot...")
startBot()
}
当我运行main.go时，出现以下两个错误：
....\go\pkg\mod\gorm.io\driver\sqlite@v1.5.0\error_translator.go:9:35: undefined: sqlite3.ErrNoExtended
....\go\pkg\mod\gorm.io\driver\sqlite@v1.5.0\error_translator.go:14:36: undefined: sqlite3.Error
我确保sqlite3已设置为PATH环境变量，并且我还安装了sqlite3的golang驱动程序"github.com/mattn/go-sqlite3"。不幸的是，我在网络上没有找到其他解决方案，所以也许这里有人可以帮我解决这个问题？
非常感谢您的帮助！

I am working on a Bot. For this purposes I have decided to use the sqlite DB and GORM as ORM. Right now i am working on a simple "Connection" file, that should connect with sqlite db (which is in the same folder as the Conection.go) and migrate the predefined structs.
package database
import (
_ "github.com/mattn/go-sqlite3"
GlobalModels "goBot/modules/global/models"
"gorm.io/driver/sqlite"
"gorm.io/gorm"
"log"
"os"
)
func Connect() *gorm.DB {
log.Print(os.Getenv("DB_PATH"))
db, err := gorm.Open(sqlite.Open("db.sqlite"), &gorm.Config{})
if err != nil {
log.Fatal(err)
}
return db
}
func Migrate() {
db := Connect()
errUser := db.AutoMigrate(GlobalModels.User{})
if errUser != nil {
log.Fatal(errUser)
}
errUserFlags := db.AutoMigrate(GlobalModels.UserFlags{})
if errUserFlags != nil {
log.Fatal(errUserFlags)
}
}
And here are the predefined structs User.go and UserFlags.go:
package models
import "gorm.io/gorm"
type User struct {
gorm.Model
Name string `gorm:"column:name"`
UserID int `gorm:"column:user_id"`
ChatID string `gorm:"column:chat_id"`
}
package models
import "gorm.io/gorm"
type UserFlags struct {
gorm.Model
UserID int
LastModuleChosen string `gorm:"column:last_module_chosen"`
User User `gorm:"foreignKey:UserID"`
}
Here is the main function, where i try to migrate this models:
func main() {
database.Migrate()
fmt.Println("Starting the bot...")
startBot()
}
When I run the main.go, the following 2 errors are occuring:
....\go\pkg\mod\gorm.io\driver\sqlite@v1.5.0\error_translator.go:9:35: undefined: sqlite3.ErrNoExtended
....\go\pkg\mod\gorm.io\driver\sqlite@v1.5.0\error_translator.go:14:36: undefined: sqlite3.Error
I have ensured, that the sqlite3 is set as env. variable in PATH and I have also installed the sqlite3 golang driver "github.com/mattn/go-sqlite3". Sadly I have not found any other solutions in the net, so maybe someone here could help me with this matter?
Thank you very much in advance!

这似乎是当前版本的GORM sqlite驱动程序（v1.5.0）的问题。https://github.com/go-gorm/sqlite/issues/142
看起来要么降级到1.4.4，要么等待新版本发布。
英文:
This appears to be an issue with the current version of the GORM sqlite driver (v 1.5.0)
https://github.com/go-gorm/sqlite/issues/142
Seems like it's necessary to either downgrade to 1.4.4 or wait for a new release.
