骨干.js和字母ID的问题

Question

I have a problem with Backbone.js. My system has inconsistency in the pattern of ID.

The fact is that the system has two types of ID:

1) id: 45 (integer, default and works properly) 2) id: app-45 (with problems)

The first problem is that the backbone "understands" this ID (id: app-45) as (id: app: 45)

The second problem is when I'll run an update, and the backbone sends the ID to 0.

Follows the details of the request:

Headers: Request URL: localhost(...) Request Method:PUT Status Code:200 OK

Request payload:

{"id":" app:120368", "title":"Test"}

Preview:

reservation: { id:app:0 , title:test }

Response:

{"reservation":{"id":"app:0","title":"test"

Answer 1

You could always override the .parse() and .toJSON() methods of your model to transform id values, eg

var Model = Backbone.Model.extend({
  parse: function(response){
    response.id = parseInt(response.id, 10); // or whatever function is appropriate
    return response;
  },
  toJSON: function(){
    var attrs = _.clone(this.attributes);
    attrs.id = "app-" + attrs.id; // or whatever reverses the transformation
    return attrs;
  }
})
