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.
I mean, the mvc for cairngorm and the one in rails don't overlap their functionalities? I'm not sure I understand the need for cairngorm with the rails backend..
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?
The application is used through Facebook. I click the button and the flash contains the notice while create is being executed, but after that it's empty again. It doesn't survive a redirect.
i'm trying to figure out how i can handle login protected actions in RoR (Ruby on Rails) with Flex without using weborm or rubyamf remoteobject.I'm in the situation where i have to fill a datagrid with results of an HTTPService request after i log in correctly into my application. Can anyone suggest me the way to accomplish that?
I'm trying to upload a Dynamically generated file from Flex (PNG image) to Ruby on Rails Server back end using the following code (from Flex on Rails book):
I am trying to login in to my Rails app through an adobe flex application that uses Devise but cannot figure out how to map the AMF request to Devise::SessionsController#New. I tried the following
How do I control what parameters are passed in a RemoteObject method? I noticed that when I directly download and run the code from this site, saving an object results in the following parameter set being passed back:
I have a rails app that records a video from the webcam. After the video file is saved on the flex server, I need to create a record on the database calling the create action on my rails app from Flex. How can I achieve this? I need a url with params to be called. I think the authenticity_token is necessary to post data.
I have a webpage based on ruby on rails. For one task I need some more complex user interface which I plan to do with a flex programm. The question is, how I can start the a new window with my flex programm and hand over the right url where the flex app can load its data in XML format...
I'm looking for a way to upload images that were created in my flex app to rails. I've tried to use paperclip, but it don't seem to work. I've got this tutorial here: [URL] The problem is, that they are using a FileReference to browse for files on the clients computer. They call the .upload(...) function and send the data to the upload controller. But I'm using a URLLoader to upload a image, that is modified in my Flex-App. First, here is the code from the tutorial:
How can we include (nicely) a swf file in a Rails application?By the way, I tried the swf_fu plugin but it didn't work. When I call my swf file located in the swfs directory, it tells me that the method is not found:
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?
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
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?
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.
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)?
I want to upload a file(photo) from Flex to Rails and then send a response back to the server in XML (contains photo URL and ID). I'm sending from my Rails server some XML as follows:[code]it doesn't seem to parse XML properly. I have used similar code before with URLLoader and it worked.
how to use flexpaper for my rails application? it needs swf formats, and our rails wud converted any supported file type to pdf.how to proceed further with converting pdf to swf on the fly and displaying it via the flexpaper app.
I'm starting to learn in flex and ruby on rails. I see some projects there is a flex folder under rails_project/app which contains controller, models, views. I think it's not mannually to add these folders to rails project.
What is the best way for flex frontend to communicate with backend writted in C#? The only communication channel in HTTP, so no custom sockets.I used SOAP in the past, but am concerned about performance since the large overhead of xml, and this application I'm currently working on will be pretty data intensive.Anything that supports easy setup and transparent marshaling/unmarshaling is OK.Is there something as BlazeDS for .net?
I am curious to know if there is a way of connecting a flash front-end to a C++ driven backend? I'm not currently working on a project that involves this, but I found out about an application used in the gaming industry, called Scaleform, that requires knowledge on doing such things in order to create menus in games.
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?
I have developed a Flex application. I have also developed a Java servlet program for an Access database using Tomcat. How can I use that servlet backend for my Flex application using HTTPService ?
I've made a website, to test the html5 audio. Unfortunately some browser doesn't support it. How to use a flash backend? I haven't found anything useable. The flash backend examples on the web use the DOM element, not the new Audio(). I don't want to use JQuery for this little experiment.
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
