Question

Hi all I am creating my first Backbone.js app. It is basically a collection that renders the data in a table. What I want to do is to be able to filter and sort data.
What is the best way to do it? Should I use the Router or store some params that render will take into consideration.

I think the Router will get really complex soon as I am going to have 3-4 filters and 1 order option.

What do you think?

Answer 1

I would add methods on my collections for the filtering and sorting, and using a view to just render an arbitrary collection, that might be filtered or ordered.

For ordering there is a built in hook: http://documentcloud.github.com/backbone/#Collection-comparator

For filtering, check out the underscore helper methods on collections, and extend with your own.

You could for example have a collection.doFiltering([filter1, filter2, filter3]);
that returns a filtered array.
