//检测当前用户是否具备权限
func (u *UserRepository) IsRight(action string,userID int64) bool {
	permission :=&model.Permission{}
	sql := "select p.id From user u,user_role ur,role r,role_permission rp,permission p WHERE p.permission_action=? AND p.id = rp.permission_id AND rp.role_id=r.id AND ur.role_id=r.id AND ur.user_id=u.id AND u.id=?"
	u.mysqlDb.Raw(sql,action,userID).Scan(permission)
	//可以写其它判断逻辑
	if permission.ID > 0{
		return true
	}
	return false
}```
这里为什么用原生sql语句，不用gorm了呢
