Get Backbone.js to make a POST request for a new module with an specified id attribute

I'm having an issue getting Backbone to send a POST request for a newly created model for which I specified an id parameter.

For those wondering why would I need that, what happens actually in the API is that a tag that already exists in the, say http://api.example.com/tags/tag_id is beeing referenced for a given content type, eg. http://api.example.com/conent/content_id/tags. What I'm therefore trying to get Backbone to do is to make a POST request to http://api.example.com/conent/content_id/tags/tag_id when a model with that id is being created in the tags collection.

To be more RESTfull you should send POST http://api.example.com/conent/content_id/tags because POST http://api.example.com/conent/content_id/tags/tag_id means updating of existed resource.

But if you want to do it in this way you can specify url of collection:

var Content = Backbone.Model.extend({
  urlRoot: '/content'
});

var Tag = Backbone.Model.extend({});

var Tags = Backbone.Collection.extend({
  url: function(){
    return this.content.url() + '/tags';
  },
  initialize: function(models, options){
    this.content = options.content;
  }
});

var content = new Content({id: 12}),
    tags = new Tags([], {content: content});

tags.create({id: 25});
// => PUT/PATCH http://api.example.com/content/12/tags/25

It is because when your model have id Backbone is thinking that is is already existed model and trying to update it. One of the solution is pass type:

tags.create({id: 25}, {type: 'POST'});
// => POST http://api.example.com/content/12/tags/25
