# Well that's what i've done, i was just reading some shit on some blog that was giving pros and cons to both

# so my actual question is this, I have a route /register that you make a POST to.

@user_blueprint.route('/register', methods=['POST'])
def register():
    email = request.form['email']
    password = request.form['password']
    username = request.form['username']

    if isValidEmail(email) and isValidPassword(password) and \
       isValidUsername(username):
        user = User(
            email=email,
            password=password,
            username=username
        )

        db.session.add(user)
        db.session.commit()

        login_user(user)
    etc. etc.




 # In that I have the 3 funcs isValid...() eg:


def isValidEmail(email):
    if len(email) > 7:
        # https://stackoverflow.com/questions/8022530/how-to-check-for-valid-email-address
        if re.match("^.+@(\[?)[a-zA-Z0-9-.]+.([a-zA-Z]{2,3}|[0-9]{1,3})(]?)$",
                    email):
            if User.query.filter_by(email=email).first() is None:
                return True
            else:
                # return False "Error: user already exists"
    # return False "Error: not a valid email address"

def isValidPassword(password):
    # https://stackoverflow.com/questions/41117733/validation-a-password-python
    pattern = re.compile('^(?=\S{6,20}$)(?=.*?\d)(?=.*?[a-z])(?=.*?[A-Z])(?=.*?[^A-Za-z\s0-9])')
    if pattern.match(password):
        return True
    else:
        # return False "Password Requirments: 6 chars, 1 digit, 1 Uppercase, 1 special"


# This is when i get a bit lost, I want the corresponding errors to appear below the respective inputs dynamically (as the rest of the form is dynamically built, instead of hiding/showing).
# So i need to return false back to register and send the error message back to the client to be rendered clientside.

# I thought about handling all the errors for the modal (username, email, password) in one function where you pass in the input element and then insert the new <p> after and then set the innerHTML to that of the error. But im not quite sure how i would do that or if that is the best way, if there is a better/nicer way that im missing, would appreciate the help.
