Circle

Circle original implementation. Provides an easy interface to manipulate, save and restore, circle-like values from the database. Works very similar to the ActiveRecord::Point, but for a list of 1 point and 1 radius data (x, y, and r). PostgreSQL Docs

How it works

Migration

Just set the type of the column as circle when creating a table.

create_table "region" do |t|
  t.string "title", null: false
  t.circle "area"
end

Using it

The column is automatically identified and its value turned into what is defined in geometry.circle_class or into a Torque::PostgreSQL::Circle.

This original implementation provides a couple of methods:

region = Region.new
region.area.x
region.area.y
region.area.r
region.area.radius   # Same as r
region.area.center   # Which will return a point for the center

The value can be set in some different manners:

region.area = '10,10,5'
region.area = '[10,10],5'
region.area = '<(10,10),5>'
region.area = [10,10,5]
region.area = [[10,10],5]
region.area = { x: 10, y: 10, r: 5 }
