代码如下。
type xxxx struct {
ID int gorm:"column:id"
Email string gorm:"column:email"
Mobile string gorm:"column:mobile"
CompanyPhone string gorm:"column:company_phone"
BankName string gorm:"column:bank_name"
BankAccount string gorm:"column:bank_account"
}
func UpdateWwcFapiao(w []xxxx) error { if err := db.Table(tableName).Updates(w).Error; err != nil { return err } return nil }
if err := dao.UpdateWwcFapiao(w); err != nil {
log.Fatalf("udpate table wwc_fapiao is err:%v\n", err)
}
提示我:unsupported data 这个是什么原因呢 是我用的方法不对吗

Updates 方法支持 struct 和 map[string]interface{} 参数。当使用 struct 更新时，默认情况下，GORM 只会更新非零值的字段

有没有办法类似删除一样的，加一个方法就可以实现更新默认值，每次我在更新的时候都写map的方式，很不好
