1. Nessa aula vamos criar o primeiro model de Usuário.
  2. Vamos precisar instalar a biblioteca Pydantic, para isso, vamos executar o comando pip install pydantic==1.10.7.
  3. Vamos criar o arquivo user_model.py e adicionar o seguinte código: 
from beanie import Document, Indexed
from uuid import UUID, uuid4
from pydantic import Field, EmailStr
from datetime import datetime
from typing import Optional

class User(Document):
    user_id: UUID = Field(default_factory=uuid4)
    username: Indexed(str, unique=True)
    email: Indexed(EmailStr, unique=True)
    hash_password: str
    first_name: Optional[str] = None
    last_name: Optional[str] = None
    disabled: Optional[str] = None
    
    def __repr__(self) -> str:
        return f'User {self.email}'
    
    def __str__(self) -> str:
        return self.email
    
    def __eq__(self, other: object) -> bool:
        if isinstance(other, User):
            return self.email == other.email
        return False
    
    @property
    def create(self) -> datetime:
        return self.id.generation_time
    
    @classmethod
    async def by_email(self, email: str) -> "User":
        return await self.find_one(self.email == email)
