Colorized SQL Logging Backport for ActiveRecord

Thanks to the work of Chris Tonkinson (@cmtonkinson) Rails 5 will have granular SQL logging so you can easily see SELECT, INSERT, UPDATE, DELETE, and transaction statements in your log. This gem is a tested backport of that colorized logging feature.

Installation

Add this line to your application's Gemfile:

gem 'activerecord-colored_log_subscriber'

And then execute:

$ bundle

Or install it yourself as:

$ gem install activerecord-colored_log_subscriber

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bundle exec rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

We use the appraisal gem to help us generate the individual Gemfiles for each ActiveRecord version and to run the tests locally against each generated Gemfile. The bundle exec rake appraisal test command actually runs our test suite against all Rails versions in our Appraisal file. If you want to run the tests for a specific Rails version, use rake -T for a list. For example, the following command will run the tests for Rails 3.2 only.

$ bundle exec appraisal activerecord32 rake test
