Question

I need to pass a urlRoot to a model at runtime, as several different classes of the model use different urlRoots.

Here is my model:

App.Models.Table = Backbone.Model.extend({ });

And here is where I am going to use it:

var m = new App.Models.Table();
var t = new App.Collections.Tables(m, { url: this.url });
var tables = new App.Views.Tables({ collection: t, template: this.template });

this.url returns the correct value, based on the event that calls it. Am I passing my model into the collection wrong? Here is my collection:

App.Collections.Tables = Backbone.Collection.extend({
    url: this.url,
    model: App.Models.Table,
    initialize: function(models, options) {
        if (options && options.url) {
            this.url = options.url;
        }
        this.fetch({
              success: function(data, options) {

            }
        });
    }
});

How do I pass in this.url to my model?

Answer 1

Assuming this.url is the correct url in your example, then do the following:

table = new App.Models.Table({
    id: id
});
table.urlRoot = this.url;
