"go package main import ( "fmt" "github.com/astaxie/beego/orm" _ "github.com/go-sql-driver/mysql" "time" ) type Userinfo struct { Uid int `orm:"pk"` Username string Departname string Created time.Time } func init() { orm.RegisterModel(new(Userinfo)) orm.RegisterDataBase("default", "mysql", "momaek:123456@/test?charset=utf8")}
func main() { o := orm.NewOrm() user := Userinfo{Username: "hello", Departname: "wd"} id, err := o.Insert(&user) fmt.Printf("ID:%d, Err: %v\n ", id, err) user.Uid = 3 user.Created = time.Now() user.Departname = "wakkkk" num, err := o.Update(&user) fmt.Printf("Num:%d ,ERR: %v\n", num, err) u := Userinfo{Username: "hello"} err = o.Read(&u) fmt.Println(u) fmt.Printf("ERR: %v\n", err) num, err = o.Delete(&u) fmt.Printf("NUM: %d, Err: %v\n", num, err) }"
代码是这样的。然后运行报错：
ID:47, Err: Num:0 ,ERR: {0 hello 0001-01-01 00:00:00 +0000 UTC} ERR: missed pk value NUM: 0, Err: missed pk value 
beego的orm默认应该把
id int作为主键read, update, delete的时候必须有主键,应该只有create的时候不需要，因为主键是auto的。你主键设置是正确的
其实建议主键是这样的
然后这段代码，比如read，beego orm 执行的时候，会找到主键，获取主键的值value，然后执行
select fields from user where uid = value,你的主键的值不存在(0)，orm就没法执行select， 当然会报错http://jinzhu.me/gorm/curd.ht...
感觉这个 orm 更好用一些。
通过先查询，查找改主键是否有值Read()
Insert Update Delete
