Sinatra::Hashfix - Use HashWithIndifferentAccess for Sinatra params

Get your hash fix! Many people have been confused by Sinatra’s partial implementation of a Rails style params[] hash:

This gem replaces the default Sinatra params hash with HashWithIndifferentAccess (from ActiveSupport).

Installation

You know this tune:

gem install sinatra-hashfix

If you are using a classic (one-file) Sinatra app, just add:

require 'sinatra/hashfix'

If you are using a modular Sinatra::Base app, you must also add:

register Sinatra::Hashfix

To the top of your application class.

Request:

/my/route?foo=1

Without:

params[:foo]            # 1
params.has_key?(:foo)   # false
params.has_key?('foo')  # true

With:

params[:foo]            # 1
params.has_key?(:foo)   # true
params.has_key?('foo')  # true

It’s the little things in life that make me happy.
