Technology Option For Implementing RIA With Rails As Backend?

Jan 19, 2010

I'm working on a application that requires a feature-rich media view, including images, videos, and smooth sequencing based on capture time. The backend is currently written in Rails.

What's currently the best, most mature option for implementing RIAs with Rails on the backend? I've looked at Flex, Laszlo, and ExtJS. ExtJS is interesting to me because I'm really not a fan of pure Flash UIs, but it seems highly targeted towards business apps, not entertainment applications like this.

Ruby On Rails :: Implementing Drag Calendar With Flex And Rails

Jul 12, 2009

I want to implement an application in Flex/Rails in Background as I know these two languages but I'm fairly beginner with Flex and Intermediate-to-expert with Rails. My application will display a calendar like object by which there are say 5-day week or 7-day week or a month (30-days) and in each day there will be some data such as appointments or such. I want users to be able to drag left or right to get more days after or before the displayed week for example and I want the boxes to be filled with proper appointments data.

What is the best way to implmenet this in your opinion, mainly from Flex point of view? Any architectural tips from the Rails side?

Ruby On Rails :: Understand Rails Authentication W/r/t Assets Like Swfs

May 21, 2009

I am a rails noob. I am having a problem conceptualizing how assets work in an authenticated system. All of the tutorials I've seen so far talk about putting your swfs in the public folder and embedding them in your view. However, the swf I'm using is a flex gui that should only be used by users logged-in through restful-authentication. I imagine that putting the gui into the public folder would be defeating the whole purpose of having an authentication system. So what is everybody doing to restrict access to this kind static content?

Ruby On Rails 3 :: Embed A Flash File In A Rails Project?

Mar 24, 2012

I am trying to embed a flash file onto the homepage of my Ruby application. The homepage is in /app/view/home, and the flash file is in the projects /public/flash/myflash.swf.When I load the home page, I don't see anything, although the text is bumped below a square of the proper size I defined the file as.The code I am using to try and load the file is

<div id="flashContent">
<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="346" height="383" id="Blox" align="middle">
<param name="movie" value="/flash/Blox.swf" />
<param name="quality" value="high" />

[code]....

I am thinking that either I am calling the file wrong by using value=/flash/Blox.swf, or that I am storing my flash file in the wrong place period. How can I get my flash file to load?

Ruby On Rails :: Recording Audio Through RTMP/Rails?

Apr 26, 2010

I am in the process of building a rails/flex application which requires audio to be recorded and then stored in our amazon s3 account. I have found no alternative to using some form of RTMP server for recording audio through flash, but our hosting environment will not allow us to install anything like FMS, Red5, etc.

Is there any existing Ruby/Rails RTMP solution that will allow audio recording? If not, is it possible for Rails to at least intercept the RTMP stream and then I can hope to reference red5's source or something for parsing the data (long shot, I know)?The other alternative I can think of is hosting a red5 server on another host and communicating with our rails app once the saving/uploading is done, which is not preferred.

Ruby On Rails :: Flex App Embedded In Rails App W/ Authentication

Dec 20, 2010

We have a Rails 3 app using session-based authentication (modified acts_as_authenticated), and a Flex app that needs to be embedded in an html.erb template. The Flex app needs to access routes that have a before_filter set to check if the user is logged in. When interacting with the HTML site, this causes the user to be redirected to a login page, then sets a Rails session property (tied to a cookie) to record that the user is logged in when making future requests.The Flex app needs to access XML that's generated by Rails (behind the before_filter) and I don't want to force the user to log in twice -- what should I be passing as a flash parameter to the Flex app so that it can present as "already logged in" if that session exists (ie, the user has logged in via the HTML interface)?

C# :: How To Serialize Objects In Flex For Backend

Sep 26, 2009

We are developing an app with a Flex frontend and a C# backend, connected through web services. We are using the FLex Builder 3's Web Service Manager to autogenerate the webservice classes. The problem araise when Flex serialize our objects, for example, when we have a Number property with no value, this is serialized as NaN, and our backend doesn't know about NaN. Another example is when we serialize a cyclic reference, we get a stack over flow exception. I know in java, for example, you can configure the way xstream work with cyclic reference... So, the question is, can we change the way Flex serialize the objects so C# can work with this frontend? Is there any issue we should know about how flex serialize objects?

ActionScript 3.0 :: Flash - Backend Swfaddress?

Mar 11, 2011

My problem here is actually not actionscriptbased but more of a backend problem.But I just can't figure this out & neither can the webhotel. When I run a flashsite on other webhotels everything is working when it comes the seo part. (Running the site with javascript deactivated - browsing the underlying html-site that is created with php, using the same principles as the But on my client's website (another webhotel) there are problems.

For example: ults in 404 error and a message that biography.swf does not exist. I always get redirected to some imaginary swf-files thus giving me 404 errors or to swf-files that happens to have the correct file names. I've checked the .htaccess file and they look exactly the same. In fact I have uploaded the complete site to another webhotel and everything works perfect. I can browse the underlying html-site without any problems.The support at the my client's webhotel doesn't seam to understand how this solution work. They think I'm doing some seo-tweeks that they can't give any support for. But something is clearly wrong here and it seems that something is different on their servers
