## Object

对 object 操作的三个方法 Insert / Update / Delete
```go
o := orm.NewOrm()
user := NewUser()
user.UserName = "slene"
user.Password = "password"
user.Email = "vslene@gmail.com"
obj := o.Object(user)
fmt.Println(obj.Insert())
user.UserName = "Your"
fmt.Println(obj.Update())
fmt.Println(obj.Delete())
```
### Read
```go
var user User
err := o.QueryTable("user").Filter("id", 1).One(&user)
if err != orm.ErrMultiRows {
	fmt.Println(user.UserName)
}
```
### Create
```go
profile := NewProfile()
profile.Age = 30
profile.Money = 9.8

user := NewUser()
user.Profile = profile
user.UserName = "slene"
user.Password = "password"
user.Email = "vslene@gmail.com"
user.IsActive = true

fmt.Println(o.Object(profile).Insert())
fmt.Println(o.Object(user).Insert())
fmt.Println(user.Id)
```
创建后会自动对 auto 的 field 赋值

### Update
```go
var user User
err := o.QueryTable("user").Filter("id", 1).One(&user)
if err != orm.ErrMultiRows {
	fmt.Println(user.UserName)
}
user.UserName = "MyName"
o.Object(&user).Update()
```
### Delete
```go
o.Object(user).Delete()
```
Delete 操作会对反向关系进行操作，此例中 Post 拥有一个到 User 的外键。删除 User 的时候。如果 on_delete 设置为默认的级联操作，将删除对应的 Post

删除以后会清除 auto field 的值
