Recursively decodes Typhoeus encoded arrays in given Hash.
@param hash [Hash]. This Hash will be modified!
@return [Hash] Hash with properly decoded nested arrays.
# File lib/rack/typhoeus/middleware/params_decoder/helper.rb, line 25 def decode!(hash) return hash unless hash.is_a?(Hash) hash.each_pair do |key,value| if value.is_a?(Hash) decode!(value) hash[key] = convert(value) end end hash end
Recursively decodes Typhoeus encoded arrays in given Hash.
@example Use directly in a Rails controller.
class ApplicationController before_filter :decode_typhoeus_arrays end

If the Hash is an array encoded by typhoeus an array is returned else the self is returned
@param hash [Hash] The Hash to convert into an Array.
@return [Arraya/Hash]
# File lib/rack/typhoeus/middleware/params_decoder/helper.rb, line 61 def convert(hash) if encoded?(hash) Hash[hash.sort].values else hash end end
Checks if Hash is an Array encoded as a Hash. Specifically will check for the Hash to have this form: {'0' => v0, '1' => v1, .., 'n' => vN }
@param hash [Hash]
@return [Boolean] True if its a encoded Array, else false.
# File lib/rack/typhoeus/middleware/params_decoder/helper.rb, line 49 def encoded?(hash) return false if hash.empty? keys = hash.keys.map{|i| i.to_i if i.respond_to?(:to_i)}.sort keys == hash.keys.size.times.to_a end
