Backbone model.save()不会将ID附加到URL的末尾

Question

我有一个问题,骨干PUT请求返回405(方法不允许).发生这种情况是因为代码中的model.save()没有发送到具有模型ID的模型URL.

这是PUT.

如果我通过REST控制台执行,并将ID添加到它的URL工作.但直接从这段代码:

      this.model.set($(e.currentTarget).data("modelfield"), $(e.currentTarget).val());
      console.log("model",this.model);
      this.model.save({
          success: function(model, response){
            console.log("Yup!");
            $(self.el).find('.update_loader').removeClass("running");
            $(self.el).find('.update_loader').addClass("done");
          },
          error: function(){
            console.log("No!");
            $(self.el).find('.update_loader').removeClass("running");
            $(self.el).find('.update_loader').addClass("error");                
          }
      });

在发布之前的控制台上的模型,肯定有一个ID.为什么不能正确形成URL？

型号定义:

define([
'jquery',
'underscore',
'backbone',

], function ($, _, Backbone){

    var ContactModel = Backbone.Model.extend({
      url: "http://localhost:670/api/contacts"        
    });

    return ContactModel;

});

设置Model.url只为模型提供一个常量URL.如果要附加模型ID,则需要指定Model.urlRoot.这将生成"/ api/contacts/id"形式的URL:

var ContactModel = Backbone.Model.extend({
  urlRoot: "http://localhost:670/api/contacts"        
});

或者,如果模型存储在集合中,则可以设置Collection.url为相同.请参阅以下注释Model.url:

委托Collection#url生成URL,因此如果此类的所有模型共享一个公共根URL,请确保已定义URL或urlRoot属性.ID为101的模型存储在Backbone.Collection中,其URL为"/ documents/7/notes",将具有以下URL:"/ documents/7/notes/101"
