Filtering a Backbone Collection returns an array of Models

Question

Sample Code:

this.books = this.getBooksFromDatabase();
this.publishedBooks = this.books.filter(function(book) {
  return book.get(\"isPublished\") === \"1\";         


        

Answer 1

You could either instantiate a new backbone collection and pass in the array.

var myPublishedBooks = new MyBooksCollection(publishedBooks);

Or you could refresh your original collection.

this.books.refresh(publishedBooks)

---

Note that the 0.5.0 release in July 2011 renamed refresh to reset, so you can achieve this in newer versions of Backbone with;

this.books.reset(publishedBooks)
