How to get particular model in backbone.js

Question

As i made a collection of Users in backbone, I added few users in users collection and it is added.now i want to remove the a particular user from my collection with particular username.

So what i have done is i made a method in my collection:

user: function(username) {
    return this.filter(function(user){ return user.get('username')==username; });
  }

and then i access it like this:

App.Users.user(data.username);

then for removing a particular element i do:

App.Users.remove(App.Users.user(data.user));

and for updating the user data i do:

App.Users.user(data.username)[0].set(data)

Please check my code, and suggest if i can improve it any ways.

Answer 1

Instead of App.Users, use App.Models.Users. This will increase readability. Everything else seems fine to me.

Answer 2

If a username is unique, then you should use this.detect() instead of this.filter(). It would be slightly faster and also I believe also returns a single model instead of an array...

If the username isn't unique, ignore this...

Also, you should use '===' instead of '=='.
