Flask-User-Base is a Flask boilerplate app that makes it easy to create a web application that can support users. The app only uses Flask and common Flask extensions to minimize the learning curve. The extension Flask-User handles all user related code including user registration, user login, email confirmation, and password resets so the developer can get started with writing application specific code. A secondary purpose of this repository is to demonstrate how to incorporate Flask-User in a Flask project.

Flask-User has been implemented in the models to support all optional data-models including multiple email accounts per user and user roles. These can be easily changed if needed by referring to the Flask-User data-models documentation. Flask-User's built in templates have been duplicated in a directory in the application's primary templates folder to allow for Flask-User's templates to be customized if desired, as documented here. If no customization is desired, all Flask-User templates can be removed from the templates folder.

This app can be deployed on Heroku immediately and includes the Heroku-related files Procfile and runtime.txt. These files can be removed if Heroku deployment is not needed.

Inside the config.py files and the setup.py file, the app is referred to as "Project." A case sensitive search and "replace all" operation in the project's root directory is all that is needed to customize the name of the app.

The following instructions are for MacOS. See the Installation part of the Flask documentation to run the app on other operating systems.

1. git clone this repository
2. python3 -m venv venv to create a new virtual environment
3. . venv/bin/activate to activate the virtual environment (deactivate the virtual environment with deactivate)
4. pip3 install -r requirements.txt to install/update all requirements
5. pip3 install --editable . in the root directory to install the application package

1. . venv/bin/activate to activate the virtual environment
2. python3 run.py to run the app
3. View the app in a web browser at http://localhost:5000

0. The application is configured to create a sqlite database called dev.db in the top-level folder when it is run locally
1. flask db init to create the migration repository
2. flask db migrate to have Alembic compare the db schema with db file
3. flask db upgrade to apply changes to the db file

1. On Heroku, set the environment variable ENV to 'prod' which loads config.py from the instance folder instead of the root directory
2. heroku addons:add heroku-postgresql:hobby-dev to create a Postgres database
3. Set SQLALCHEMY_DATABASE_URI to Heroku's DATABASE_URL environment variable in the config.py file in Flask's instance folder
4. Use Flask Migrate's flask db init and flask db migrate commands to generate migrations
5. Push the migrations folder to Heroku
6. heroku run python3 manage.py db upgrade --app app-name to upgrade the production database

0. brew install postgresql to install Postgres with Homebrew
1. brew services start postgresql to start
2. brew services stop postgresql to stop

1. Use the command heroku pg:pull DATABASE_URL new_db_name -a heroku_app_name which creates a new local Postgres database with the name new_db_name and the same database schema and content of your Postgres database on Heroku. A database with the same name must not already exist. You can use a tool like Postico to view and manage your local Postgres databases with a GUI.
2. Configure your Flask app to use the new Postgres database. Assuming Flask-SQLAlchemy is being used, in Flask's configuration set SQLALCHEMY_DATABASE_URI = "postgresql://localhost/new_db_name".
3. Now that Flask recognizes the new local Postgres database mirroring the production database, use Flask-Migrate's flask db init and flask db migrate commands to generate a migration script.
4. Push the migrations folder generated by Flask-Migrate to Heroku.
5. Use Flask-Migrate to upgrade the production database on Heroku with heroku run flask db upgrade -a heroku_app_name.
