ActiveRecordRecord

ActiveRecord Record is a Railtie that instruments ActiveRecord and records SQL queries, model instantiations, and view renders. Every request cycle will open a next TextEdit window with a summary of the request.

Note: at the moment this development tool is Mac only.

Installation

Add this line to your application's Gemfile:

gem 'active_record_record', git: 'https://github.com/cantino/active_record_record'

And then execute:

$ bundle

Usage

Because the instrumentation added by this gem is slow, it remains off by default. To enable, you must be in the Rails development environment and provide COUNT_OBJECTS=true in the ENV. For example by running:

$ COUNT_OBJECTS=true rails s

You will often want to reload twice to see an accurate accounting of SQL queries.

You can also wrap a section of code with track_time_as to get a breakdown for that section.

track_time_as("this block seems slow") do
  10_000.times do
    # SLOW SQL!
    # LOAD ALL THE OBJECTS!
    # RENDER ONE MILLIONS PARTIALS!
  end
end

Development

To release a new version, update the version number in version.rb, and then run bundle exec rake release to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
