```Python

```Python
UserInDB(
    username="john",
    password="secret",
    email="******@****.***",
    full_name=None,
)
```

或更精准，直接使用 `user_dict`（无论它将来包含什么字段）：

```Python
UserInDB(
    username = user_dict["username"],
    password = user_dict["password"],
    email = user_dict["email"],
    full_name = user_dict["full_name"],
)
```

#### 用另一个模型的内容生成 Pydantic 模型 { #a-pydantic-model-from-the-contents-of-another }

    // Helper methods

    private Object getFieldValue(Object obj, String fieldName) {
        try {
            Field field = getField(obj.getClass(), fieldName);
            field.setAccessible(true);
            return field.get(obj);
        } catch (Exception e) {
            throw new RuntimeException("Failed to get field value: " + fieldName, e);
        }
    }
