Origin
Selectable extensions¶ ↑
For generating more dynamic queries with Mongoid :)
Usage¶ ↑
gem 'origin-selectable_ext'
Or include in .gemspec
file as dependency ;)
Example usage¶ ↑
From the money-mongoid
gem (also used in Timespan)
class Money class << self def custom_serialization?(operator) return false unless operator case operator when "$gte", "$gt", "$lt", "$lte" true else false end end def custom_specify(name, operator, value, options = {}) money = value.__evolve_to_money__ case operator when "$gte", "$gt", "$lt", "$lte" specify_with_multiple_currencies(name, operator, money, options) else raise RuntimeError, "Unsupported operator" end end def custom_between(field, value, options = {}) { "$gte" => ::Money.new(value.min, value.iso_code), "$lte" => ::Money.new(value.max, value.iso_code) } end def custom_between? field, value true end private def specify_with_multiple_currencies(name, operator, value, options) currencies = [value.currency.iso_code] currencies.concat options[:compare_using] if options && options[:compare_using] multiple_money_values = value.exchange_to_currencies(currencies.to_set) subconditions = multiple_money_values.collect {|money| specify_with_single_currency(name, operator, money)} if subconditions.count > 0 {"$or" => subconditions} else subconditions[0] end end def specify_with_single_currency(name, operator, value) {"#{name}.cents" => {operator => value.cents}, "#{name}.currency_iso" => value.currency.iso_code} end end end
