if the user tries this, the user fails the unique constraint in the database
find out a way to fix this so that the app catches it
[ ] Add an alert and redirect to the create user page
probably needs try and except statements to work

Fixed the error by adding a try: and except: statement in the function in the model.py file. I then added an if statement for the alert that is mapped to the cannot_create boolean. Screen Shot 2019-06-17 at 12 48 43 PM
