I have Django 1.7 with PostgreSQL 9.3 behind.
I want to store a model with geometrical field circle and be able to get true or false if a given point is within the stored geometrical circle. I found that question and that library and also this option, so I got lost...
What is the right and simpler way to do it, is it better to save a point and a radius and then calculate it (so I need to install the django-postgres-geometry?), or should I update Django and PostgreSQL?
