Rails - Aug 2011 - JSON PUT/POST/UPDATE

Hey all... I''m building a RESTful JSON API and I find myself writing
this:

JSON.parse(request.body.read)

...over and over in every controller action that accepts JSON in the
request body (which is a lot of actions).

Does rails have a better built-in way to keep the code more DRY?  Or
should I solve that somehow myself?

Thanks,

Cainus

If the content-type is set properly on the request, rails should
populate params with the parsed json itself.

You can also use to_josn method to get the json string. Its built-in method
in rails.
when request arrives at server you can get json data in parameter which you
can fatch by params[:<json root name>]
You can view the whole request ad json in rails by using req.as_json method.
