Getting headers on Backbone.Collection.prototype.fetch

gistfile1.coffee

# Actually more of an example of how to pick headers value and put them in Backbone collections. 

class HeadersAwareCollection extends Backbone.Collection
  parse : (resp, xhr) ->
    @total = xhr.getResponseHeader('X-Total-Results')
    super

# Alternatively, call `xhr.getAllResponseHeaders()`, parse the text, and add the whole object to
# the collection.

# Thanks @philoye for pointing out that `parse` is a better fit than `fetch` for this!
