Task Lister

My First Web Application in Python-Flask.

Description

1. This is a basic web application, which allows the user to login and create tasks/to-do items.
2. User creates task by entering the task heading, task description and the deadline (till when the task is to be completed) .
3. The user can update, delete the tasks accordingly. The application also sends email notification to the registered email about the deadline of the task.

Working

• The user has to first register himself/herself using basic details like email.
• Once the registration is complete the user gets a Welcome Email.
• The user can the login and start creating tasks.
  • The user gets an email notification 24 hrs prior to the task deadline.

Note

• In config.py use your own environment variables
  • database URL
  • Email (Mandatory for email notification)
  • Password (Mandatory for email notification)

Environment Variable	Description
SECRET_KEY	Secret key for your application
MAIL_SERVER	Mail server for the email notifications
EMAIL	Email address from which notifications would be sent
EMAIL_TOKEN	Password for the email address account
TASK_LISTER_DEBUG	To specify if the environment is production or development
TASK_LISTER_KOYEB_DB	Database URL for the database hosted on Koyeb

Note on psycopg2 in Flask

When using psycopg2 in Flask, ensure that the database URI starts with postgresql:// instead of postgres://.

For example, use:
postgresql://username@localhost:5432/template1

SQLAlchemy previously supported both postgres:// and postgresql://, but support for the postgres scheme has been removed. Make sure to update your connection string to avoid compatibility issues.

Setting Up Google SMTP for Sending Emails

If you are using a Google SMTP server for sending emails in your application, follow the steps below:

1. Log in to your Google account.
2. Navigate to Google Account Settings.
3. Go to 2-Step Verification and enable it if not already enabled.
4. Access App Passwords from the security settings.
5. Provide a desired name for the app and click Create. This will generate a password for your application.
6. Copy the password displayed on the screen and use it as the value for the EMAIL_TOKEN environment variable in your application.
