running_count

Counter caches for Rails applications, including cached running counts.

Installation

Add this line to your application's Gemfile:

gem 'running_count', '~> 0.2.1`

And then execute:

$ bundle

Usage

class Course < ActiveRecord::Base
  belongs_to :user

  keep_running_count :user
end

class User
  has_many :courses
end

Tracks the number of Course records associated with the User model, saving them to the courses_count field in the 'users' table.

Also tracks a dynamic running count in the running_courses_count method on the User model.

Reconciling changes

Course.reconcile_changes

Will update the 'users' table with the number of associated courses in the courses_count field, and clear the dynamic cache.
