This gem extracts params given as a hash to structured data, that can be used when creating queries

http://github.com/vicentemundim/query_string_interface

This is a gem, so you can install it by:

sudo gem install query_string_interface

Or, if you are using rails, put this in your Gemfile:

gem 'query_string_interface'

To use it, just extend QueryStringInterface in your document model:

class Document
  include Mongoid::Document
  extend QueryInterfaceString

  # ... add fields here
end

Then, you can use some class methods with your ORM syntax:

def self.filter_by(params)
  where(filtering_options(params)).order_by(*sorting_options(params))
end
