CleanParams

Clean Params is a Ruby gem for use with Rails to access the controller parameters cleanly. No more ugly hash accesses. No more flooding your codebase with multiple condition checking. With clean_params you can specify various rules to parse your params hash inside the initializer file. It also allows for nested hash parsing.

Installation

Add this line to your application's Gemfile:

gem 'clean_params'

Run the generator to create the initializer file. You can specify your parsing rules here.

rails g clean_params:install

Usage

Example initializer file -

CleanParams.configure do |config|
  config.params = {
    # Customize your params here
    'key' => ['key', 'Key']
  }
end

Example params hash -

params = {"utf8"=>"✓", "authenticity_token"=>"123", "Key" => "key", "token"=>"323344", "customer_detail"=>{"caller_id"=>"123", "customer_name"=>"XYZ"}}

And goodies -

params = CleanParams.clean(params) # params - rails params hash
params.key # => key
params.token # => 323344
params.caller_id # => 123

Or you can include it inside the filter in ApplicationController and use the object inside any controller.
