Updating the application

In this section, we’ll update the routes to use the new authentication model. Lastly, we’ll update the POST route for adding an event to populate the events field in the user’s record.

Updating the user sign-in route

In routes/users.py, update the imports:

from fastapi import APIRouter, Depends, HTTPException, status
from fastapi.security import OAuth2PasswordRequestForm
from auth.jwt_handler import create_access_token
from models.users import User

We have imported the OAuth2PasswordRequestForm class from FastAPI’s security module. This will be injected into the sign-in route to retrieve the credentials sent over: username and password. Let’s update the sign_user_in() route function:

async def sign_user_in(user: OAuth2PasswordRequestForm = Depends()) -> dict:
    user_exist = await User.find_one(User.email == 
    user.username)
    ..
