A curated list of seed projects crafted with basic modules on top of Flask, a leading backend framework powered by Python. Open-source seed project enhanced with OAuth for Github, Dark-Mode, DB tools (Flask-Migrate), and Docker Support – Soft Dashboard Design.
- Working with a timestamp based on UTC is a good standard to follow.
- Lines 3 to 6 import the built-in pathlib as well as the third-party libraries connexion, SQLAlchemy, and Marshmallow.
- A curated list of awesome streaming video tools, frameworks, libraries, and learning resources.
- You remove the datetime import, the get_timestamp() function, and the PEOPLE dictionary.
Config.py gets the necessary modules imported into the program and configured. This includes Flask, Connexion, SQLAlchemy, and Marshmallow. It would be much better if what you got back for person was a Python object, where each of the fields is an attribute of the object. That way, you make sure that the objects contain the expected value types and not any malicious commands. Lines 8 and 9 iterate over people and print out the data of each person. By using the sqlalchemy option, you also install packages that helps your Flask app leverage the powers of SQLAlchemy.

With all these changes in place, it’s time to update your front-end code and leverage Swagger UI to try out if your database works as expected. Next up, you’ll update the existing functions connected to the endpoints listed above so that they can work with the people.db database. The moment you removed the PEOPLE dictionary, your Python code editor may have complained about the undefined PEOPLE variable in your code.
As you learned above, writing SQL may not only feel inconvenvient, but it can cause security issues. If you don’t want to worry too much about database interaction, a package like SQLAlchemy can help you out. You’re going to follow a database convention of naming the table as singular, so the table will be called person. python api design Database tables usually have an auto-incrementing integer value as the lookup key to rows. Each record in the table will have a primary key whose value is unique across the entire table. Having a primary key independent of the data stored in the table gives you the freedom to modify any other field in the row.

After you import the sqlite3 module, you can create a new database with .connect(). If you have a look at your file system after defining the conn variable, then you’ll notice that Python created the people.db database file right away.
