我后面使用TiDB,可直接连接多个地址,所以使用了 dbresolver。 在创建gorm时,发现使用了一个nil的gorm.Dialector。后面db.AutoMigrate 就会读到空指针。 请问这里 gorm.Open 是必须要传入一个正确的链接么?后面不是已经使用了dbresolver了吗? 辛苦解答一下,谢谢。
db, err := gorm.Open(nil, &gorm.Config{}) if err != nil { return err } err = db.Use(dbresolver.Register(dbresolver.Config{Sources: dias, Policy: dbresolver.RandomPolicy{}}))
