Build your first REST API with Flask and PostgreSQL

It's been a while! Learn how to create a home automation web service to store and retrieve temperatures in different rooms of your house (Arduinos not included!). Using Flask we can easily build an API that your temperature sensors can send data to, and then we can retrieve the data or do some processing with it.

This video will help you learn how to build a simple Flask API using PostgreSQL for data storage.

Thank you very much for watching!

did you read my mind? i was just wishing for this!

[playcode]

excelente, ainda não tinha experimentado python pra api.

[tanzania]

Thank you for all the explanations. I am new to APIs and wonder if you can give me a hint on how can I create an API that I can give to another person so he can share his data with me without me having access to his database and I can store the shared data in my database. I hope I am not saying something stupid. Thank you for your help. By the way, I just bought your Udemy course.

Hey, I bought two of your udemy courses on flask rest api, one got updated recently, was thinking if you are going to update the advanced one, or there is no such plan.

Hi everyone i cant do the db part because elephantsql are shutting down i cant register anything else i can use please

[ahmedsubmission]

I am getting this error once I add the db url and do flask run:

psycopg2.OperationalError: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory
Is the server running locally and accepting connections on that socket?

[benthebrute]

Any insight on using psycopg2 for windows? I attempted with and without the -binary part and got errors either way. Error: pg_config executable not found.

[LorenzoPeve]

Just wanted to point out that this is connecting to the DB using a global connection object which is not good for working with servers (concurrency issues, scaling problems, etc)

ElephantSQL is discontinuing its services. The product will reach its End of Life on January 27, 2025. I wasn't able to create an account to even follow along with this video.

Thank you for the video, but all this without an ORM as SQL-Alchemy does not seem truly professional.
