Experiment::Light

Turn features on or off in various rails environments

Installation

Add this line to your application's Gemfile:

gem 'experiment_light'

And then execute:

$ bundle

Or install it yourself as:

$ gem install experiment_light

Usage

Run install generator:

$ rails generate experiment_light:install

A yaml file named experiment.yml will be added into config/ after running install generator, now your can define your experimental features:

foo:
    development: true
    test: true
    production: false

bar:
    development: false
    test: true
    production: false

Now you can use it in models like this:

class TestModel < ActiveRecord::Base
  ...

  if experiment_on?(:foo)
    def foo_method
      ...
    end
  end

  ...
end

In controllers like this:

class TestController < ApplicationController
  ...

  def index
    ...

    if experiment_on?(:foo)
      redirect_to :back
    end

    ...
  end

  ...
end

And in views like this:

<% if experiment_on?(:foo) %>
    <p>Experiment foo is on</p>
<% end %>

<% if experiment_off?(:bar) %>
    <p>Experiment bar is off</p>
<% end %>
