How to call fetch method of Backbone Collection passing Id
backbone-views, backbone.js
Solution
Thank you for your answers, finally I got the solution from Backbone.js collection options.
Apologies that I couldn't explain the question properly while for same requirement others have done brilliantly and smartly.
Solution : I can have something like :-
var Messages = Backbone.Collection.extend({
initialize: function(models, options) {
this.id = options.id;
},
url: function() {
return '/messages/' + this.id;
},
model: Message,
});
var collection = new Messages([], { id: 2 });
collection.fetch();

Problem
I want to fire `fetch` method on Backbone Collection which would pass an Id parameter similar to what happens in `Model.fetch(id)` E.g. ``` var someFoo= new Foo({id: '1234'});// Where Foo is a Backbone Model someFoo.fetch(); ``` My Backbone collection:- ``` var tasks = backbone.Collection.extend({ model: taskModel, url: '/MyController/GetTasks', initialize: function () { return this; } }); ``` In my View when I try to fetch data:- ``` var _dummyId = 10; // // Tried approach 1 && It calls an api without any `id` parameter, so I get 500 (Internal Server Error). this.collection.fetch(_dummyId); // Tried approach 2 && which fires API call passing Id, but just after that // I am getting error as below:- Uncaught TypeError: object is not a function this.collection.fetch({ data: { id: _dummyId } }); ``` Found it very late : To cut short the above story I want something like Get /collection/id in backbone.
