问题 I am setting up the backbone sync mechanism and am a bit confused where to generate the id's for the models. When I create a new model, should backbone be generating and setting the id, or am i supposed to implement an id generation method, or is there some sort of mechanism where I "PUT" the data to the server, which generates the id and returns a model with the id? 回答1: or is there some sort of mechanism where I "PUT" the data to the server, which generates the id and returns a model with
