   How about a FlexOnRails version of the real Simple Content Management System? I mean the backend.

   The drag-and-drop part would suit Flex and it would be cool to see a WYSIWYG editor in a Rails scaffolding form.

   Presumably the actually site eventually generated would use a liquid design that was only div tags with unique (ie generated from the db) ids.

   Mark,

   I agree. A Content Management System was the first thing that came to my mind as well. I was thinking that you could use ImageMagick and RMagick as part of the backend.

   Mark and Derek, funny you should mention that but I’m halfway through a Flex app built with the cairngorm framework and a ruby on rails backend. It uses Flex Data Services(via Weborb). There’s an early screenshot here: http://www.flickr.com/photos/maccman/228526299/ I’ve also just been making a asset manager. When the cms is finished I’ll release it under the MIT license and contribute it to your code. If anyone would like to help or to look at the current code, please email me (maccman@gmail.com).

   Nevermind, got it. I was close before. I had to copy the Flex files from the Flex Source\flex_issuetracker\bin to the rails public directory and navigate to http://localhost:3000/flex_issuetracker.html . Simple, really, just the included docs don’t say anything about it.

   Good point. I’ve update the files so that all you have to do is boot up your server and open a browswer to http://localhost:3000, except for the directory explorer sample. For that one you should point your browser to: http://localhost:3000/examples/flex_directory_explorer.html

   For the open source RIA application with Flex on Rails, why not a TimeSheet application…The UI would be a Calendar (as the iCal in Mac), and we should enter the activities…
   What do you think?

   I am a 2nd year IT BSc student, and am really very impressed with the power of Flex on Rails.

   In my opinion it would have been better if you or we could work on a sample project starting from basic to advance set of apps so that those who are still unaware of flex.

   Then you will automatically get more flex enthusiast. this will bring a long term benfit as the comunity will start to grow!

   Hi folks,
   Thanks Derek…

   Has anyone actually got any of these samples working – on Webrick?

   [...] This is unexpected news (to me, at least). Riding Rails reports that Adobe is releasing an official Rails SDK for Flex Flex on Rails. Read more at Flex on Rails. [...]

    We have developed a visual goal management sollution on three different platforms: Java, .net, and vb/flash. We are now looking at doing a RIA with flex based on the action script code we already developed. Ruby seems very attractive in this context as well.
    We could imagine doing this in a semi-open source fashion, with the programmers earning shares of the project based on theire contribution.
    It would be great to discuss the possibilities…

    Hi,

    I just started on flexonrails.. and to be honest, I know absolutely zilch. I started from your article over at
    
    adobe but I couldnt understand why I cannot get it to work by pointing my browser to a localhost:3000 something.

    Now I found out your SDK but I still cannot understand what was the difference that enabled the issue tracker to be displayed on the localhost:3000

    Can you enlighten me?

    I have Flex 2 builder btw.

    Thanks

    Hi Kay,

    If you want to launch an app by pointing your browser to http://localhost:3000 you will need to put the swf file for your Flex app in the public folder of your Rails app, and you will need to replace the index.html file in there with with html file that Flex Builder generates for your app.

    I am new to this technology. I am using code from given examples in SDK with flex 3, actionscript 3 and rails for embedding upload functionality in my application. But I am getting the IO error at run time when i run it from flex builder. And when i run it using ruby script/server it runs without any error but doesn’t write any file on disk. Please help me fixing this bug.
    Code i used is:

    —————————application.rb————————

    # Filters added to this controller apply to all controllers in the
    application.
    # Likewise, all the methods added will be available for all
    controllers.

    class ApplicationController ‘3a8f77511f4633ed7c0cb6065d614fec’

    def upload_file
    file_data = params[:Filedata]
    file_name = params[:Filename].to_s
    file_path = params[:folder].to_s
    File.open(file_path + “/” + file_name, “wb”) { |new_file|
    new_file.write(file_data.read) }
    render(:xml => “”)
    end
    end
