ParamsPurifier

Have you ever had problems with multiple select and empty strings being sent in array params? (see discussion). Now you can easily solve that problem by using ParamsPurifier!

Build Status

Gem Version

Coverage Status

Installation

Add this line to your application's Gemfile:

gem 'params_purifier'

And then execute:

$ bundle

Or install it yourself as:

$ gem install params_purifier

Usage

Just include ParamsPurifier::Purifiable module in your controller (e.g. ApplicationController):

class ApplicationController < ActionController::Base

  include ParamsPurifier::Purifiable

end

And that's it! You have an access to "purified" params by purified_params method. Works with Strong Parameters by default (it returns an instance of ActionController::Parameters):

def user_params
  purified_params.require(:user).permit(:email, :password, :password_confirmation)
end
