Ruby On Rails :: Why Is My First RoR App On Dreamhost Running So Slow

Aug 26, 2009

I've got my first RoR app deployed to Dreamhost and it's using Passenger. The one note on Dreamhost's wiki about slow response mentioned changing a RewriteRules line in the public/.htaccess file to use FastCGI. But I assume this will have no effect if I'm using Passenger, is that right? I've looked at the logs and compared them to my local logs, and it looks like there is a wider range on Dreamhost. Some responses are comparable to the quick local ones, others can take a few seconds. I'm using a Flex front end with HTTPServices to the rails backend, and I think I also need to add logging around my services to see what kind of network delay I'm getting and try to isolate where the delays are. I should also add that there is probably plenty of room for improvement in the area of eager loading associations. I think I did that a little early on, but haven't done it thoroughly through all the associations. I have the local logs set to the default where I can see all the queries, and there are a lot of them.

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)?

Ruby On Rails :: Using Flash And Cross Domain?

Nov 14, 2010

I'm running a rails3 project with an external asset host for all javascript, images, swfs etc. This is on a completely different domain. So know I tried to embed some SWFs using swfobject. In development (same host) everything works fine, but in production (different hosts) it doesn't start the flash (firebug shows the file is loaded but nothing appears on the page). I already put this crossdomain.xml file in the root of the asset host but it does not change anything at all.

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />

[code]....

What can I do to make it work? The SWFs I'm using are not developed by me, so I cannot change them. Some are simple sounds, others are videos and small "apps". I don't want to have to make rails serve the swfs.
