Statement.Changed can't work on a new custom struct #7486
Description
GORM Playground Link
Description
When hook tx.Statement.Changed on func BeforeUpdate catch "age"
create a struct, and method.
func (m *Man) update(data interface{}) error {
return DB.Set("data", data).Model(m).Where("id = ?", m.Id).Updates(data).Error
}
func (m *Man) BeforeUpdate(tx *gorm.DB) error {
if !tx.Statement.Changed("age") {
fmt.Println("no")
return nil
}
fmt.Println("yes")
return nil
}this struct have Age, so tx.Statement.Changed("age") should got yes, but got panic: reflect: Field index out of range
var change3 = struct {
Age int
}{Age: 30}
// change3 -> panic: reflect: Field index out of range
err := idx.update(change3)
if err != nil {
return
}at playground, just change1 and change2 got yes.
