rails-env

Avoid environment detection on Rails.

Installation

Add this line to your application's Gemfile:

gem 'rails-env'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rails-env

Usage

Instead of checking for the current environment like this:

if Rails.env.production?
  # Do something with Rails.configuration
end

You can just use:

Rails.env.on(:production) do
  config.assets.version = '1.0'
end

Looks dumb, but you don't have to use the long Rails.configuration or assign it to a local variable. This is useful when you're extracting out things to initializers.

To match all environments, use :any.

Rails.env.on(:any) do
  config.assets.version = '1.0'
end

Upgrading from previous versions

Previous versions used to yield the configuration; this is no longer true on 1.0+.

So, instead of using

Rails.env.on(:development) do |config|
  config.assets.version = '1.0'
end

use

Rails.env.on(:development) do
  config.assets.version = '1.0'
end
