Вот оно. Этот код должен работать с любой структурой.
def parse(path, value, hash)
key, rest = path.split('.', 2)
if rest.nil?
hash[key] = value
else
hash[key] ||= {}
parse(rest, value, hash[key])
end
end

if hash.is_a?(Hash)
hash.each do |key, value|
hash[key] = if value.is_a?(Hash) && value.keys.all? { |k| k !~ /\D/ }
arr = []
value.each do |k, v|
arr[k.to_i] = conv_to_array(v)
end
arr
else
conv_to_array(value)
end
end
hash
else
if hash !~ /\D/
hash.to_i
elsif hash == 'true'
true
elsif hash == 'false'
false
else
hash
end
end
end
