Apartment Rental MVP
https://github.com/than1089/apartment-rentalAn MVP featuring all the necessary functionalities for an apartment rental web app.
Users have multiple options on the login page: log in with a password, log in with Facebook, and log in with Google. After three consecutive failed login attempts, users will be blocked, with admins having the ability to manually unblock them via the admin dashboard.
There are three types of accounts: normal users, agencies, and admins. Agencies can list apartments for rent, while admins have full management capabilities. Users can search for apartments based on criteria such as the number of rooms, area, and price range.
A key challenge in this project was implementing GeoDjango and PostGIS or SpatiaLite to store longitude and latitude coordinates for apartments. Additionally, GIS technology facilitates querying by distance in comparison to the preferred location.
