How do we check if a User already exists in Flask Restful Api
If we wanted to use this API in a mobile app, how would we check if the user already exists and them sign them in?
I think Kenneth Love handles that in the video. The
create_user class method first checks to see if the user exists (based on email or username) before trying to actually add the new user to the database.
But, more or less, you first want to use the information provided by the user to check the database for an existing user object/resource (with whatever you are using, in this case an SQLite database and the Peewee ORM), and only create one if it doesn't exist.
