` validate_py(self)` causes error when a variable is using alias

[wasdee]

validate_py(self) causes error when a variable is using alias i.e. scopes: List[str] = Field(alias='scope'). This also causes incompatible to use with fastapi. I personally think that the function validate

    def validate_py(self):
        """Validates but also adds None for the removed fields.
        The first init validates all current info and adds None to fields that were del
        The second init validates all the None fields to make sure they can be None."""
        BaseModel.__init__(self, **self.dict())
        BaseModel.__init__(self, **self.dict())

Could be changed to solve this. For example, we could use orm style creation to avoid the error. I still not fully understand the process of the library. please advice. 😂

for the workaround, i creates 2 class and use the orm to convert them.
