#failure(name, request, data) ⇒ Object

Called when a request is not able to handled. This could be because a record could not be created or saved.

def failure(name, request, data)
  handle(:failure, name, request, data)
end

#serialize(request, data) ⇒ Object

Serializes the data passed in, first looking for a custom formatter, then falling back on trying to call to_ on the data. If neither are available, returns an error with the status code 406.

def serialize(request, data)
  name = request.params[:format].to_sym
  formatter = to_format(name)
  formatter[data] || request.error(406)
end

#success(name, request, data) ⇒ Object

Called when a request is handled successfully. For most GET requests, this is always the case. For update/create actions, it is when the record is created/updated successfully.
