Multi Email App

The Multi Email App builds on the features of Basic App:

- Internationalization

- Login, Change password and Logout

- Register with Username and Email, Change username

- Email confirmation, Forgot password

- the create_app() application factory pattern

And adds the following:

- Multiple Emails per User (v0.5.1 and up)

This app requires appropriate SMTP configuration.

Create multi_email_app.py

Create ~/dev/example/multi_email_app.py with the content below.

Make sure to adjust the MAIL_* settings below to the correct SMTP server and SMTP account settings.

Highlighted code shows what was added to the Basic App.

!! This recipe requires Flask-User v0.5.1 or up !! Please upgrade earlier versions.

In a nut shell:

- Define User model (username, password, etc)

- Define UserEmail model (user_id, email, is_confirmed, is_primary, etc)

- Define one-to-many relationship between User and UserEmail

- Register User and UserEmail class through SQLAlchemyAdapter()

- Visit /user/manage-emails as an authenticated user.

Run the Multi Email App

Run the Multi Email App with the following command:

cd ~/dev/example
python multi_email_app.py

And point your browser to http://localhost:5000.

If you receive an SendEmailError message, or if the Registration form does not respond quickly then you may have specified incorrect SMTP settings.

If you receive a ‘AssertionError: No sender address has been set’ error, you may be using an old version of Flask-Mail which uses DEFAULT_MAIL_SENDER instead of MAIL_DEFAULT_SENDER.

If you receive a SQLAlchemy error message, delete the multi_email_app.sqlite file and restart the app. You may be using an old DB schema in that file.
