pg_decorator

PgDecorator

This gem is inspired by marginalia by 37signals but instead of patching Rails, patches Pg gem

PgDecorator adds first line of caller (tries to detect place in your code by ignoring gems, ruby and rbenv lines) as /* SQL comment */ so you could later identify "strange" or long queries in your PostgreSQL log directly.

Several reasons for creating gem:

• marginalia did not decorate some of PostgreSQL adapter queries
• no Rails 'dependency', you can use this gem if you use pg gem directly, or if you have non rails wrapper, such as pg_helper
• having aggressive connection pooler in front of database server may lead to loss of "set application_name = 'newappname';",

Installation

Add this line to your application's Gemfile:

gem 'pg_decorator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pg_decorator

Usage

in your ruby script add following:

 require 'rubygems'
 require 'pg_decorator'
 PgDecorator::Injector.inject('AppToRuleWorld', '/home/ruby/world_ruler)

If you use Rails then you could create config/initializers/pg_decorator

 PgDecorator::Injector.inject(Rails.application.class.to_s.split("::").first, Rails.root.to_s)
