I recently completed the Lynda.com tutorial for AngularJS, and they show an example in which they used a JSON file to filter and sort the "airport data". However near the end they replace the actual file with an API that calls the database and returns data in JSON format.
How do I do that part on the backend? How do I have a database with JSON APIs? What's the best place to start?
I have some experience with frameworks like Django for the backend, so ideally Python would be the language on the backend.
