The new code that implements the database access is added on top of a simple, open-source codebase that serves a few nice pages converted to Jinja Templates. Add a new column and 'Migrate' the databaseįlask Database - The Initial Codebase.Add a new table ('Stats') and use Flask CLI to save data.Integrate SqlAlchemy - ORM used to access the information.Add new dependencies - SqlAlchemy, Flask-Migrate.The initial codebase - the starting point.

Flask Atlantis Dark - the same UI with more modules and features.Flask Database Sample - source code (MIT License), Github.For simplicity, SQLite is used but settings can be upgraded with ease to use more powerful DBMS like MySQL or PostgreSQL - the source code for Flask Database Sample can be found on Github. The necessary code is added progressively on top of a simple codebase from zero to the migration phase. This article explains how to configure and connect Flask to an SQLite Database using SqlAchemy as a connection layer.
