Using a backport from a Rails 3, Restfulie responders enhance your response without you even noticing.
Creating
First, the new 201 support with correct headers in one cute line, supported by the created responder:
@item = Item.create(params[:item])
respond_with @item, :status => :created
Rendering
Rendering a resource using a hypermedia based representation:
@item = Item.find(params[:id])
respond_with @item
Without any extra configuration, the cacheable responder will enhance your results with last modified headers.
Caching, expiration and 304
It’s also trivial to leverage your system by providing an expiration policy. Reverse proxies, intermediate caches and clients will benefit from caching and 304 results:
@items = Item.all
respond_with @items, :expires_in => 2.minutes
Of course, cache and 304 support is also handled on Restfulie’s client side implementation.
This is it.
Extreme simplicity is about achieving conventioned behavior with one line of code, custom ones with a longer line.
Trying to make http and hypermedia usage easier than it already is.
There are a few design issues related to module include-inheritance that will be improved prior to the next release.
