RGeo::ActiveRecord is an optional RGeo module providing spatial extensions for ActiveRecord, as well as a set of helpers for writing spatial ActiveRecord adapters based on RGeo.
RGeo is a key component for writing location-aware applications in the Ruby programming language. At its core is an implementation of the industry standard OGC Simple Features Specification, which provides data representations of geometric objects such as points, lines, and polygons, along with a set of geometric analysis operations. See the README for the “rgeo” gem for more information.
RGeo::ActiveRecord is an optional RGeo add-on module providing spatial extensions for ActiveRecord, as well as a set of helpers for writing spatial ActiveRecord adapters based on RGeo. Generally, you will not interact directly with this library
RGeo::ActiveRecord has the following requirements:
Ruby 1.8.7 or later. Ruby 1.9.2 or later preferred.
RGeo 0.2.4 or later.
ActiveRecord 3.0.3 or later. Earlier versions will not work.
Arel 2.0.6 or later. Earlier versions will not work.
Generally, ActiveRecord adapters which depend on this module should be installed as gems, and they will install this module automatically as a dependency. However, you can also install it manually as a gem:
gem install rgeo gem install rgeo-activerecord
See the README for the “rgeo” gem, a required dependency, for further installation information.
This gem has not yet been tested in a large variety of environments, and we are still rapidly fixing bugs. We still consider it to be in early alpha, but we are working toward an initial production deployment at GeoPage.
We are also currently working on a mechanism for constructing complex spatial queries via extensions to Arel. This work is in the experimental stage, and requires the Rails 3.1 / Arel 2.1 head.
