上例中 ，从 `user_in.dict()` 中得到了 `user_dict`，下面的代码：

```Python
user_dict = user_in.dict()
UserInDB(**user_dict)
```

等效于：

```Python
UserInDB(**user_in.dict())
```

……因为 `user_in.dict()` 是字典，在传递给 `UserInDB` 时，把 `**` 加在  `user_in.dict()` 前，可以让 Python 进行**解包**。

这样，就可以用其它 Pydantic 模型中的数据生成 Pydantic 模型。

#### 解包 `dict` 和更多关键字

接下来，继续添加关键字参数 `hashed_password=hashed_password`，例如：

```

### 4. Disable user

Disable user `newuser`.

```
mc admin user disable myminio newuser
```

Disable group `newgroup`.

```
mc admin group disable myminio newgroup
```

### 5. Remove user

Remove the user `newuser`.

```
mc admin user remove myminio newuser
```

Remove the user `newuser` from a group.

```

Da wir in obigem Beispiel `user_dict` mittels `user_in.dict()` erzeugt haben, ist dieser Code:

```Python
user_dict = user_in.dict()
UserInDB(**user_dict)
```

äquivalent zu:

```Python
UserInDB(**user_in.dict())
```

... weil `user_in.dict()` ein `dict` ist, und dann lassen wir Python es „entpacken“, indem wir es `UserInDB` übergeben, mit vorangestelltem `**`.

	user.Account.Number += "new"

	var user3 User
	DB.Preload("Account").Find(&user3, "id = ?", user.ID)

	CheckUser(t, user2, user3)
	lastUpdatedAt := user2.Account.UpdatedAt
	time.Sleep(time.Second)

	if err := DB.Session(&gorm.Session{FullSaveAssociations: true}).Save(&user).Error; err != nil {
