Database Counters

Enables the use of fragment caching in ActionMailer views.

Adds two database counters to the log for a request:

  • total number of requests that were made
  • total number of rows that were returned



script/plugin install git://github.com/mikedemers/database-counters.git


Enabling in a Controller:

class ApplicationController < ActionController::Base
  database_counters :on
  # ...

Will result in log output like so:

Completed in 847ms (View: 0, DB: 5 Calls: 92 Rows: 671) | 200 OK [http://localhost/]

Or, in older (< 2.2) versions of Rails:

Completed in 0.05835 (17 reqs/sec) | Rendering: 0.00007 (0%) | DB: 0.00265 (4%) Calls: 5 Rows: 6 | 200 OK [http://localhost/]

Note: this plugin was built for Rails 2.x and won't be useful in a modern environment. Information on this page is for historical purposes only.
