construct() 方法的 _fields_set 关键字参数是可选的,但是允许您更精确地知道哪些字段是初始化时设置的,哪些是具有默认值的。如果该参数被省略,那么 __fields_set__ 将只包含数据提供的键。 例如,在上面的示例中,如果未提供 _fields_set 参数,new_user.__fields_set__ 将会是 {'id', 'age', 'name'}...
其中,field_name是字段的名称,field_type是字段的类型,Optional表示字段是可选的,default_value是字段的默认值。 例如,我们可以创建一个包含字符串和整数字段的动态模型: 代码语言:txt 复制 class DynamicModel(BaseModel): name: Optional[str] = None age: Optional[int] = None 使用动态模型类创建实例,并传入...

But, right now I can no longer create an instance without having to pass values to fields that are supposed to be set only in .env or loaded from environment. It is really nice that it now offers autocomplete (same goes to BaseModel) and it actually still works. It's just that I ...
