2 more JSON / XML feature parity patches before Rails 2.0

I'd really like to see just 2 more functional changes to the JSON
serialization/encoding before we get to Rails 2.0.

First, and I think this is really crucial because without it all the
efforts to output JSON from ActiveRecord objects would have been half
in vain, is to allow us to do this in controllers:

  @authors = Author.find(:all)

  render :json => @authors.to_json(:only => :name)

Currently you can only to_json on a _single_ AR::B instance, but not
for lists of them. I've a patch at http://dev.rubyonrails.org/ticket/9751
that does this but needs verification and probably more input.

The other change, while not as serious, is to get an unambiguous Time,
Date and DateTime #to_json format, i.e. to get dates encoding to JSON
like this:
  2007/10/01 12:15:02 CDT
instead of:
  0/01/2007 12:15:02 CDT

gbuesing has a patch at http://dev.rubyonrails.org/ticket/9750 that
needs your help with verification and ideas on whether this different
date format would work.

This is the last sprint before Rails 2.0 I'm guessing so if you use
JSON at all please do chip in! Thanks for listening.

I agree!!! Please!!!

Thanks for checking in http://dev.rubyonrails.org/ticket/9751 (and
improving a few things too), bitsweat!

I've added another patch based off gbuesing's for his ticket
http://dev.rubyonrails.org/ticket/9750 that requires more input and
testing across different platforms.

If anyone can help verify and test it or point out any flawed
assumptions, it'd be very very helpful.

Thanks!

I have a very heavy javascript app that depends on JSON responses from
the server. It's been using this excellent asp.net JSON serializer
and have been running fine. I based my decision to port my server code
to rails because most of my app was in the javascript with very
minimal server code. Pretty much all the server did was serialize the
database tables/rows into json for the client. But, to my sunrise,
rails was completely not suited for this out of the box!

Anyways, I'll definetly test this out since I have a great need for
this support.
