• ENVIRONMENT: Enable (development or production).
• FLASK_APP: Entry point of your application; should be wsgi.py.
• FLASK_DEBUG: Toggle debug mode on (True) or off (False).
• SECRET_KEY: Randomly generated string of characters used to encrypt your app's data.
• SQLALCHEMY_DATABASE_URI: Connection URI of a SQL database (ie: mysql+pymysql://myuser:[email protected]:1234/mydatabase)
• REDIS_URI: Connection URI of a Redis instance (ie: redis://:[email protected]:1234)
• LESS_BIN (optional for static assets): Path to your local LESS installation via which lessc.
• ASSETS_DEBUG (optional): Debug asset creation and bundling in development.
• LESS_RUN_IN_DEBUG (optional): Debug LESS while in development.
• COMPRESSOR_DEBUG (optional): Debug asset compression while in development.

Remember never to commit secrets saved in .env files to Github.

sample .env file

Thanks for the tutorial! There are a quite a few dependencies to get this working, a sample .env file would be useful.

Action Required: Fix Renovate Configuration

There is an error with this repository's Renovate configuration that needs to be fixed. As a precaution, Renovate will stop PRs until it is resolved.

Error type: undefined. Note: this is a nested preset so please contact the preset author if you are unable to fix it yourself.

requirements.txt is empty

User logged-in can access to /login using browser "go back" after login success

First thanks for this.
Like specified in title,
when a user is logged-in, he can access to /login using browser "go back"
(if I refresh from "/login", redirect to "/" ok)

@auth_bp.route('/login', methods=['GET', 'POST'])
def login():
    """
    Log-in page for registered users.
    GET: Serve Log-in page.
    POST: Validate form and redirect user to dashboard.
    """
    if current_user.is_authenticated:
        print(current_user.is_anonymous)
        return redirect(url_for('main_bp.dashboard'))  # Bypass if user is logged in

When I go back (after login success) "current_user.is_authenticated" never printed like they don't go here :/
(same with the print before the if).
Can you explain please if you see something ?
Regards
