Rails and Flash Filereference - receiving HTTP 422

Trying create a multiple file uploader in flash using RoR. I'm using AS3 scripts I use to send to PHP. Modified it a bit, and created some rails script like below...

My thoughts: It may be the auth token I need to validate, but I tried passing that in POST and no luck.

Anyone know simply how to upload files from Flash Actionscript to Ruby on Rails???
class DataFile < ActiveRecord::Base
 
  def self.save(data, name, directory)
  		path = File.join(directory, name)
  		File.open(path, 'wb') do |file|
  			file.puts data.read
		  end
		  #File.open(path, "wb") { |f| f.write(params[:filedata].read) }
  end
end
 
class UploadController < ApplicationController
	def index	
		data = params[:filedata]
		name = params[:Filename]
		
		directory = "public/data"
		
		@data_file = DataFile.save(data, name, directory)
 
		render :nothing => true
	end
end

Open in new window

I am not too sure about the RoR part, but here is an article on how to send it to a PHP script...

http://scoopmedia.be/uploading-files-using-actionscript-30-and-php


I assume, this would be the same with any server-side environment...

Yeah thanks.. doesn't do me much good. I've been working with PHP for a while, I'm trying to switch to Rails.

Is Your AD Toolbox Looking More Like a Toybox?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

"Anyone know simply how to upload files from Flash Actionscript to Ruby on Rails???"


I gave you the flash part, because that is my responsibility...  if you need help only with the Rails code, and your actionscript is working perfectly, then I would have a Mod post this question in the proper area...


And since your question was worded in a way that make it sound like you believe you can use Flash to do system uploads, I wanted to give you that information...

I had the AS part, like I said above.. I've been using a Flash upload I made for PHP for a while, but I just need help sending it to Rails.

the question was just added to the wrong area then...  if you want, I can have it removed from the AS area.

Sure if you think so. But it is an AS question also. I want to know specifically what is needed to communicate with Ruby in AS (if there is anything different)..

I believe I said it above... you communicate with all server-side code the same way...  it is the method that might change...

like Flash Remoting VS Web Services VS sending a QueryString.  it is all the same, and if it is working for PHP, then it is most likely your RoR code that is the issue.

Also, since you have not posted any Actionscript, there there is no way for a Flash person to help you with the Flash part  :)

Alright.. well another thing was I wasn't sure if I needed to pass Auth codes from Rails into flash for it to work too.

Since I have never worked with RoR, I don't know the specifics to what is needed as a call...

if you are needing to pass parameters in your call to the server, then that is simple enough...


what version of AS are you using?   post your code that does this part...

Hey, I figured it out! Kept messing with it. I turned off the authenticity token using:

skip_before_filter :verify_authenticity_token, :only => 'upload_action'

Then I looked in the Shell while I performed actions through html (which I got working), and Flash and saw that the variables had different names, so I had to change that

=)

lol...  then I guess that should have been your question...  and I would have said, that depends on what method you use to connect to the server  ;)

Thanks. my question for the most part is answered. The only dilemma I'm facing now is how to actually use the authenticity_code and pass it to Rails. I can receive it in Flash, but I'm not able to get rails to accept it.
