To expand a little on what mike has already said.
In addition to the 'regular' rails http methods. GET, POST, PUT, DELETE
there is another request type: OPTIONS
Before a cors-aware browser will do your POST/PUT request, it sends it's
own request in secret
the browser sends a request using the OPTI
Mike,
I think you're right and I would love to do what they did at that link (add
HTTP headers at the controller level), but the code never gets that far,
the OPTION is rejected by Rails first.
Since I haven't been able to get the rack-cors gem working at all, even
with Ian's observation that
Hi Scott,
>From the first line of your stack trace you can see the request method is
actually OPTIONS which is a preflight CORS request:
*Processing ApplicationController#index (for xx.xxx.xx.xxx at 2014-10-22
14:31:28) [OPTIONS]*
The application needs to send a response for the OPTIONS request
It's easy to forget how far Rails has come until you try to maintain a
Rails 2 app :)
Judging by this Railscast[1], it sounds like 2.3 does support Rack
middleware, so you might still be in luck. It looks like maybe you just
need different syntax. Instead of:
config.middleware.use Rack::Cors

Ian,
Thanks!
Unfortunately, there is no guidance to be had on using rack-cors with Rails
2. Besides adding the gem to Gemfile:
*gem 'rack-cors', :require => 'rack/cors'*
initialization should likely go in config/environment.rb, like:

Scott,
It looks like Rails is receiving an OPTIONS request and choking on it.
This is generally an indication of CORS taking place (on PUT/POSTs with
CORS, it first performs a "pre-flight" OPTIONS request to see if the
actual request is allowed). I'm not sure what kind of stuff you have
set up in
A client with a Rails 2 app that displays games written in Flash is having
them converted to HTML5/Javascript. The team doing the conversions has no
problem reading the player's data with a Javascript function like this,
which I bound to a button click and ran with the Chrome debugging console
