以下是bug，加粗的地方是需要添加的地方:
bug1:
func (c *PermissionController) Save() {
flash := beego.NewFlash()
pid, _ := strconv.Atoi(c.Input().Get("pid"))
name, url, description := c.Input().Get("name"), c.Input().Get("url"), c.Input().Get("description")
**if pid == 0{
flash.Error("请添加父节点")
flash.Store(&c.Controller)
c.Redirect("/permission/add?pid=", 302)**
}else if pid > 0 && len(name) == 0 {...}
bug2:
func (c *PermissionController) Update() {
flash := beego.NewFlash()
id, _ := strconv.Atoi(c.Ctx.Input.Param(":id"))
pid, _ := strconv.Atoi(c.Input().Get("pid"))
name, url, description := c.Input().Get("name"), c.Input().Get("url"), c.Input().Get("description")
**if pid == 0{
flash.Error("请添加父节点")
flash.Store(&c.Controller)
c.Redirect("/permission/edit/" + strconv.Itoa(id), 302)**
}else if pid > 0 && len(name) == 0 {...}
bug3:
func (c *UserController) UpdateAvatar() {
flash := beego.NewFlash()
f, h, err := c.GetFile("avatar")
**if err == http.ErrMissingFile {
flash.Error("请先上传文件")
flash.Store(&c.Controller)
c.Redirect("/user/setting", 302)
}**
defer f.Close()
if err != nil {
flash.Error("上传失败")
flash.Store(&c.Controller)
c.Redirect("/user/setting", 302)
return
bug4:

功能改进，为了让新手更好的理解beego框架的orm，我把sql语句全部改成了orm操作：
改进1:
//删除角色权限
func DeleteRolePermissionByPermissionId(permission_id int) {
o := orm.NewOrm()
permission := Permission{Id:permission_id}
o.QueryM2M(&permission,"Roles").Clear()
}
改进2:
//删除文章的回复
func DeleteReplyByTopic(topic *Topic) {
o := orm.NewOrm()
replies := Reply{Topic:topic}
o.Delete(&replies)
}
改进3:
//通过用户ID删除回复
func DeleteReplyByUser(user *User) {
o := orm.NewOrm()
reply := Reply{User:user}
o.Delete(&reply)
}
改进4:
//通过角色ID删除旧的角色权限
func DeleteRolePermissionByRoleId(role_id int) {
o := orm.NewOrm()
role := Role{Id:role_id}
o.QueryM2M(&role,"Permissions").Clear()
}
改进5:
//通过角色id和权限id保存角色权限
func SaveRolePermission(role_id int, permission_id int) {
o := orm.NewOrm()
role := Role{Id:role_id}
permission := Permission{Id:permission_id}
o.QueryM2M(&role,"Permissions").Add(&permission)
}
改进6:
//通过角色ID查找角色拥有的权限
func FindRolePermissionByRoleId(role_id int) []*Permission {
o := orm.NewOrm()
role := Role{Id:role_id}
o.LoadRelated(&role,"Permissions")
return role.Permissions
}
改进7:
//通过用户ID来查询权限
func FindPermissionByUser(id int) []*Permission {
o := orm.NewOrm()
var permissions []*Permission
o.QueryTable("permission").Filter("Roles__Role__Users__User__Id",id).All(&permissions)
return permissions
}
改进8:
//查询用户是否有这个权限
func FindPermissionByUserIdAndPermissionName(userId int, name string) bool {
o := orm.NewOrm()
var permission Permission
o.QueryTable("permission").Filter("Roles__Role__Users__User__Id",userId).Filter("Name",name).All(&permission)
return permission.Id > 0 //如果能查到数据，那么id肯定大于0
}
改进9:
//通过用户ID删除用户权限方法1
func DeleteUserRolesByUserId(user_id int) {
o := orm.NewOrm()
user := User{Id:user_id}
o.QueryM2M(&user,"Roles").Clear() //清除所有原始关系
}
改进10:
//保存用户权限
func SaveUserRole(user_id int, role_id int) {
o := orm.NewOrm()
user := User{Id:user_id}
role := Role{Id:role_id}
o.QueryM2M(&user,"Roles").Add(&role)
}
改进11:
//通过用户ID查找用户角色
func FindUserRolesByUserId(user_id int) []*Role {
o := orm.NewOrm()
user := User{Id:user_id}
o.LoadRelated(&user,"Roles")
return user.Roles
