Login Form and Register Form on one page

Some websites may prefer to show the login form and the register form on one page.

Flask-User (v0.4.9 and up) ships with a login_or_register.html form template which requires the following application config settings:

• USER_LOGIN_TEMPLATE='flask_user/login_or_register.html'
• USER_REGISTER_TEMPLATE='flask_user/login_or_register.html'

This would accomplish the following:

• The /user/login and user/register URLs will now render login_or_register.html.
• login_or_register.html now displays a Login form and a Register form.
• The Login button will post to /user/login
• The Register button will post to /user/register

Hashing Passwords

If you want to populate your database with User records with hashed passwords use user_manager.hash_password():

user = User(
        email='user1@example.com',
        password=user_manager.hash_password('Password1'),
        )
db.session.add(user)
db.session.commit()

You can verify a password with user_manager.verify_password():

hashed_password = user.password
does_match = user_manager.verify_password(password, hashed_password)

Account Tracking

Flask-User deliberately stayed away from implementing account tracking features because:

• What to track is often customer specific
• Where to store it is often customer specific
• Custom tracking is easy to implement using signals

Here’s an example of tracking login_count and last_login_ip:

# This code has not been tested

from flask import request

@user_logged_in.connect_via(app)
def _track_logins(sender, user, **extra):
    user.login_count += 1
    user.last_login_ip = request.remote_addr
    db.session.commit()
