在对象的字段而不是对象上调用方法？

Question

This code has some objects representing a user and the admin who created that user. It's a trimmed down version of some code submitted to us by an applicant. The code is broken and deletes the admin when you try to delete the user (as demonstrated by main). Why does u.Delete call the admin's delete instead of the user's delete?

package admin
import "fmt"
type Admin struct {}
func (Admin) Delete() {
    fmt.Println("deleting admin")
}

package user

import (

    "fmt"

    "admin"

)

type User struct {*admin.Admin}

func (*User) D

In your sample code the letter e in User's Delete method is not of the same encoding as the letter e in Admin's Delete method. Since Go supports utf8 this is not an error but it is a different method. Fix the e in User's Delete method and all should work as expected.
