Sinatra::Hashfix - Use HashWithIndifferentAccess for Sinatra params

Sinatra::Hashfix - Use HashWithIndifferentAccess for Sinatra params¶ ↑

Get your hash fix!

Sinatra only partially implements a Rails style params[] hash, which can lead to confusing behavior, since methods like has_key?() and delete() don’t work as you’d expect:

groups.google.com/group/sinatrarb/browse_thread/thread/af4b40e610d4daf/bc953ca6d118a882

This gem replaces the default Sinatra params hash with HashWithIndifferentAccess (from ActiveSupport). Purists may balk, but this is all about avoiding bugs.

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.

Example¶ ↑

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.

sinatra-hashfix's Issues

Why do you choose system ruby version?

My Debian PC can't build sinatra-hashfix. Because it stops with following error.
Why do you choose /usr/include/ruby-2.1.0/ruby/ruby.h? I think it's a header file on system ruby version....
