Rails JSON request is not parsed correctly into post parameters

Question

I\'m trying to debug a problem where Rails isn\'t decoding the JSON POST data.

The server logs show:

2011-12-14T06:44:44+00:00 app[web.2]: Started POST 
         


        

Answer 1

before_filter :fix_ie_params, only: [:create, :update]

For Thin:

def fix_ie_params
  if request.format == '*/*'
    # try to JSON decode in case of IE XDR
    begin

      params.merge! ActiveSupport::JSON.decode(request.body.string)

    rescue Exception=>e
      # todo: log exception
    end
  end
end

For Unicorn and Phusion Passenger:

def fix_ie_params
  if request.format == '*/*'
    # try to JSON decode in case of IE XDR
    begin

      request.body.rewind
      params.merge! ActiveSupport::JSON.decode(request.body.read)

    rescue Exception=>e
      # todo: log exception
    end
  end
end
