PeriodicCounter

Maintains period fields on any counter column in your database

Requirements

sudo gem install periodic_template

Create columns

For every counter column (X), you should also have a X_computed_at datetime column.

To define period columns, use this format: X_last_1_week or X_last_6_hours.

The name the period column should follow the format of ActiveSupport's time extensions:

http://api.rubyonrails.org/classes/ActiveSupport/CoreExtensions/Numeric/Time.html

Create configuration

Create a file, config/counters.yml:

my_table_name:
  - my_counter

The plugin assumes that the config directory also houses your database.yml file.

Create cron entry

Add the following command to your crontab at a period of your choosing:

cd /path/to/your/app && RAILS_ENV=production periodic_counter
