Handler crashed with error runtime error: hash of unhashable type models.Device

[zxysilent]

不确定是不是 xorm 的bug 使用了

sess := Db.NewSession()
defer sess.Close()
sess.Begin()

出现下面问题 Handler crashed with error runtime error: hash of unhashable type models.Device

如果不用 直接使用Db 则没有错误

models.Device 结构体可以贴下？

[zxysilent]

type Device struct {

你的版本？

[zxysilent]

go 1.9 // Version show the xorm's version Version string = "0.6.0.1022"

[lunny]

更新到最新版本再试下？

[zxysilent]

同样的问题 // Version show the xorm's version Version string = "0.6.3.0713"

我也遇到了这个问题, 也是在事务里, 使用的是pg:

log:

我的struct:

type CustomerProfile struct {
    GroupId   int       `xorm:"pk" json:"group_id"`
    Phone     string    `xorm:"pk" json:"phone"`
    Name      string    `json:"name"`
    Belong    string    `json:"belong"`
    Expand    KVExpand  `xorm:"json" json:"expand"`
    Status    int       `json:"-"`
    CreatedAt time.Time `xorm:"created" json:"-"`
    UpdatedAt time.Time `xorm:"updated" json:"-"`
}

// 客户资料, 以kv形式保存
type KVExpand struct {
    Keys   []string `json:"keys"`
    Values []string `json:"values"`
}

已使用了最新版617e0ae295d7fd8a4ea48f6c782781f6cc367c7e.

解决了: 将CustomerProfile.Expand定义为*KVExpand即可正确计算hash值.
