Backbone.js: urlRoot with http query string?

Question

In Backbone.js I can appoint where the model fetches it's data:

var Book = Backbone.Model.extend({urlRoot : '/books'});
var mybook = new Book({id: "1"});
mybook.fetch();  //it will access '/books/1'

But if I want to append a query string after the URL? e.g. the book data is at /books/1&details=true. Can I specify this in model?

Solution 1

You will have to use a custom url function for the model.

Book.url = function() {
  return this.urlRoot + '/' + this.id + '?details=true';
};

Solution 2

You can also use the option for the method fetch

mybook.fetch({data:{details: true}});

Although the accepted comment works, this seems to be the 'backbone way'

I wish there was a way to define it on a model/collection level. this way you have to pass the data each time you call the fetch, would be nice if you could just set the data once on the model itself.
