#as_json(options = {}) ⇒ Object

Fix to bug due to ActiveSupport::Serialization JSON.

it calls as_json in order to get the hash representation of the object
ActiveSupport uses all object attributes, including item.invoice who force
the json convertion into an infinite loop:

. (invoice -> items -> item -> invoice -> items -> item …)

def as_json(options={})
  Hash[to_h.map { |k, v| [k.to_s, options ? v.as_json(options.dup) : v.as_json] }]
end

#to_h ⇒ Object

This iterates over all fields and if is an array (items and guias) converts it to hash using to_h
