bone.js无法获取单个模型

Question

I'm having a problem fetching a model that is outside of a collection. I have seen many solutions and for some reason none seem to be working (probably doing something stupid). I have a success function in my actual fetch which never fires. It should be hitting /devices/{deviceId}

Here is my code

define([
  'underscore',
  'backbone',


], function(_, Backbone) {
  // Creating backbone model
  var DeviceModel = Backbone.Model.extend({
    // set defaults
    defaults: {
    },

    idAttribute: "deviceId",
    urlRoot: '/devices'
  })
  return DeviceModel;
});

and I am calling it from

        model = new DeviceModel({deviceId: this.deviceId })

        model.fetch()

Thank you!

You could try to pass callback functions to debug what is going on with:

  model.fetch()

From the documentation of BackboneJS Model-Fetch

Accepts success and error callbacks in the options hash, which are both passed (model, response, options) as arguments.

So, you can include:

model.fetch({success: function(m, resp) { console.log(resp);}, 
               error: function(m, resp) { console.log(resp);} 
            });
