About The Project
Message in a Bottle is an application where users can discover stories about the communities around them. This app was designed as a way to interact with cities, neighborhoods, and the people that inhabit them. The Message in a Bottle backend is built with a Django framework that stores story and user data through PostgreSQL. We expose this data to our frontend team to build out the user interface.
Learning Goals
- Building a RESTful API with a Python Django backend
- Collaborating with a Front-End dev team
- Geolocation calls and tracking
- Applying best practices learned during Turing to a new language and framework
- e.g. TDD, OOP, REST, MVC(Rails) <--> MTV(Django)
- Making use of the
git rebaseworkflow
