Deployment of multiple ruby on rails application

Hi everyone,
I am on Mac OS X Server 10.5.4
I try to deploy a few rails application on the same server. Each app should be accessible like this:
http://my.domain.com/app1/
http://my.domain.com/app2/
http://my.domain.com/app3/
etc...
I followed the "Scenario 2 - Sharing a Website (Virtual Host) with the Proxied Web Application" found in the chapter 6 (p.97) of the Web Technologies Administration booklet and succesfully deployed my first application, running on port 4001 and accessible through http://my.domain.com/app1/.
I also managed to deploy the second application, running on port 4002, and accessible from http://my.domain.com:4002/app2/ but I am unable to directly access it from http://my.domain.com/app2/, I get a 404 error.
When I swap the applications order in the website list in Web>Sites, the first one appearing in the list is working and not the second one...
It is probably something stupid, but how can I access all my apps on their own path?
In advance, thank you for helping me,
Yannis

Hi Harry, and thank you so much for taking of your time for my problem.
After your last message, I launched one mongrelrailspersist server for each of my app:
app1:
prefix: /app1
cwd: ~/capistrano/app1/current
port: 4001
app2:
prefix: /app2
cwd: ~/capistrano/app2/current
port: 4002
Then I set up the reverse proxy for app1 using proxy path /app1/ and balancer member http://127.0.0.1:4001/app1/ and edited the app1.conf file of my first app (app1) following your suggestion:
<IfModule modproxybalancer.c>
ProxyPass /app1/ balancer://balancer-group/
ProxyPassReverse /app1/ balancer://balancer-group/
<Proxy "balancer://balancer-group">
BalancerMember http://127.0.0.1:4001/app1
</Proxy>
<Proxy "balancer://balancer-group">
BalancerMember http://127.0.0.1:4002/app2
</Proxy>
</IfModule>
Unfortunately, this is not enough, the server seems confused and hardly access app1 and not at all app2.
I found the following blog post that discuss the same problem: http://tonyrose023.blogspot.com/2007/01/multiple-rails-apps-with-mongrel.html
In his post, Tony Rose add a few RewriteCond: I tried to change the mod_rewrite declaration of the app1.conf file like the following but that did not work either...
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_METHOD} ^TRACE
RewriteRule .* - [F]
RewriteCond %{DOCUMENTROOT}%{REQUESTFILENAME} !-f
RewriteRule ^/app1(.*)$ balancer://app1%{REQUEST_URI} [P,QSA,L]
RewriteRule ^/app2(.*)$ balancer://app2%{REQUEST_URI} [P,QSA,L]
</IfModule>
I'm stuck again. Any suggestion?

Ruby one rails Web application

Hi, I have been working on setting up the ruby on rails application for web review that apple sent to my boss and I had some questions if people knew how to fix a few certain problems. I am not very proficient when it comes to ruby or rails, but I don't have the money to hire some one to do this for me, so I am trying to teach my self.
we are trying to get it to: -
[Priority 1] Can we convert the QT served files to be streamed rather than 'wait while downloading"? If we can't stream, we need a progress bar to track the download pace.
- [Priority 2] Web-based upload tool
- [Priority 3] Who/When an event happens: specifically, who approved the clip & when (on the website)?
- [Priority 4] Clip length displayed next to the clips.
- [Prpriority 5]simple log in and password
I know this is a lot to ask and I am not asking any one to go out of there way to figure anything out, just if any one know any reading material or tutorials and can point me in the right direction it would be appreciated.
thank you

Unless you want to learn and support a Ruby on Rails application like the one you are trying to implement, which will work, but will never be officially supported by Apple.
I would recommend you take a look at services like:
Media Silo
http://www.mediasilo.com/fcs
Wiredrive
http://www.wiredrive.com
They do very excellent jobs of offering Robust review and approval workflows.

How do I live preview a Ruby on Rails/Ember application?

I have a Ruby on Rails application and I am under the impression that Edge Code will work with locally hosted web servers to use live preview. I have set up the project settings to use the locally hosted address: http://localhost:3000/ ... However when I use Live Preview I receive the following error.
"Open an HTML file or make sure there is an index.html file in your project in order to launch live preview."
I have done so and I meet the criteria but it doesn't seem to work. Does Adobe Edge Code support this feature?

What's the file extension of the page you want to view in Live Preview? You may need to add it to the internal (not yet easily configurable) list of file extensions.

[SOLVED]Ruby on Rails won't run with apache/passenger

Hi I want to run Redmine, a Ruby on Rails application, on a personal server using MariaDB as the database and Apache with the Phusion Passenger module as the application platform. So far I am able to run Redmine with the default WeBrick server, but if I try to run it via Apache (http://192.168.1.5/redmine) I just get the directory index of /usr/share/webapps/redmine. I've been running various php webapps using this apache installation without issues but my unfamiliarity with Ruby on Rails makes me unsure how to fix this. If I create a Ruby on Rails test application as described at https://wiki.archlinux.org/index.php/Ru … figuration I get the same issue.
Using the arch wiki articles on Ruby on Rails and Redmine, This is basically how I installed things:
$ yaourt -S ruby1.9 rubygems1.9 nodejs redmine
# gem-1.9 install rails
# gem-1.9 install passenger
/opt/ruby-1-9/ and subfolders ended up having no read/exexute permissions for 'other', probably because of my umask settings, so I changed the permissions, also because apache runs as user/group 'apache'.
Ran the script that installs the passenger apache module:
# /opt/ruby1.9/bin/passenger-install-apache2-module
added to httpd.conf:
LoadModule passenger_module /opt/ruby1.9/lib/ruby/gems/1.9.1/gems/passenger-4.0.5/libout/apache2/mod_passenger.so
PassengerRoot /opt/ruby1.9/lib/ruby/gems/1.9.1/gems/passenger-4.0.5
PassengerDefaultRuby /opt/ruby1.9/bin/ruby
ServerName arch-server
DocumentRoot /usr/share/webapps
<Directory "/usr/share/webapps">
# This relaxes Apache security settings.
AllowOverride all
Order allow,deny
Allow from all
# MultiViews must be turned off.
Options -MultiViews
</Directory>
I checked if the passenger module is loaded, and judging from /var/log/httpd/error_log that seems the case:
[ 2013-07-03 22:52:22.8947 28902/b7407700 agents/Watchdog/Main.cpp:440 ]: Options: { 'analytics_log_user' => 'nobody', 'default_group' => 'nobody', 'default_python' => 'python', 'default_ruby' => '/opt/ruby1.9/bin/ruby', 'default_user' => 'nobody', 'log_level' => '0', 'max_instances_per_app' => '0', 'max_pool_size' => '6', 'passenger_root' => '/opt/ruby1.9/lib/ruby/gems/1.9.1/gems/passenger-4.0.5', 'pool_idle_time' => '300', 'temp_dir' => '/tmp', 'union_station_gateway_address' => 'gateway.unionstationapp.com', 'union_station_gateway_port' => '443', 'user_switching' => 'true', 'web_server_pid' => '28901', 'web_server_type' => 'apache', 'web_server_worker_gid' => '1001', 'web_server_worker_uid' => '1006' }

'apachectl configtest' gives 'Syntax OK'.
I followed the wiki on redmine (https://wiki.archlinux.org/index.php/Redmine), chose to use "bundle install" to install the required gems with only a 'production' environment. What worried me is that those gems are now in /root/.gems while the webserver runs as user 'apache'.
I can run Redmine at 192.168.1.5:3000 without errors using:
# ruby script/rails server webrick -e production
But if I kill it and try via apache http://192.168.1.5/redmine I get a directory content listing.

Thanks markocz, my use of sub-url was indeed the problem. With help from the linked article I did the following:
# mkdir /usr/share/webapps/phusion-passenger/
# ln -s /usr/share/webapps/redmine/public /usr/share/webapps/phusion-passenger/redmine
# chown -R root:http /usr/share/webapps/
# chmod -R g+rx /usr/share/webapps/
httpd.conf now looks like this:
LoadModule passenger_module /opt/ruby1.9/lib/ruby/gems/1.9.1/gems/passenger-4.0.5/libout/apache2/mod_passenger.so
PassengerRoot /opt/ruby1.9/lib/ruby/gems/1.9.1/gems/passenger-4.0.5

# MultiViews must be turned off.
Options +FollowSymLinks
</Directory>
RailsBaseURI /redmine
<Directory "/usr/share/webapps/phusion-passenger/redmine">
Options -MultiViews
</Directory>
Redmine now works via passenger.

Solaris 10, Ruby on Rails, Core Dumps

I am not very savvy with Solaris administration and we are having issues with configuring our system to run Ruby on Rails applications. We opted to use the Coolstack framework for our environment, thankfully without many hiccups. That said, our applications load but core dump during the second page load.
At this point, I'm not sure if it's our recent switch to Coolstack that is causing the problem. We've also worked to get a Mongrel cluster up and running, so that could also be the culprit.
What I'm looking for really is advice on how to pin down what the error is. I've learned about pstack to deal with the core dump file, but I'd have a better time understanding Chinese than that output. I also read about gdb and dbx, neither of which appear to be installed on our system. A strings on the file, another recommendation I found, spits out a bunch of gibberish.
How can I move forward in discovering the problem?

I'm having the exact same problem with my Solaris server. I can't seem to get any form of Rails running on the system, and pages generated by Rails crash after a few page loads (not always the same number).
Did you have any luck tracking down the issue? I've asked around in a number of places and come up empty-handed every time.

Ruby on rails idea

I had an idea for a ruby on rails application. Basically it is an online classroom. Teachers sign up and can make courses online, similar to moogle, but the data itself is also made by the teachers or other volunteers instead of it jsut being a course administration tool, with other resources needed for it to work, like textbooks, etc... e.g.: a full year math course, complete with tests and quizes and self check homework. It could feature a gradebook, forums, calendar of course events and such, schedules for work, interactive tutor pages for different aspects of subjects, online lessons, chat sessions, etc...
Anyways, I thought this would be a cool idea to develop, and perhaps eventually even make.

Dusty wrote:I'm sure you can justify such statements iphitus.
Yeah I can, but i had to go out earlier
Most of the teachers at my school are utterly clueless when it comes to computers, and to them it seems a big steep learning curve. Others just dont trust them. While they have an effective and working system in place, teachers won't want to switch to a computer based setup. Adding computers in adds even more room for disruption. When you have a class of thirty, all using computers, something *will* go wrong.
In year 10, it is a requirement for everyone to have a laptop computer. And teachers did let us use them, to take notes, do work, etc. But the reality is, that students will be distracted. Games of counterstrike, gameboy emulators, tetris was popular, were common.
Students could easily access webpages and such too when they desired.
The teachers were simply incapable of policing it.
A handful didnt realise you could minimise, and for those that did, some students discovered 'double desktop', aka multiple desktops. One keypress and battlefield is gone, your word document is on screen.
Dont say training, it's just not practical, no matter what, teachers will be one step behind students, and once one student finds away around something, it spreads.
And dont even consider locking computers down. With windows? pssh, good luck. It'd be easier to find a needle in a haystack than lock windows down. Linux? It's simply not ready. Linux didnt support my wireless driver for at least 6 months. Linux wireless sucks imho. Linux doesnt support many programs that the teachers and students are used to either. Dont say wine. More work, and it doesnt always provide the most consistent results.
Which leads me to another point, what real benefits does a computer provide? the ability to use Comic Sans MS?
Sure you can use programs like OneNote (windows oriented school ) or other things to take well organised notes, but I betcha, I could find anything in my handwritten notes faster than any computer note taker.
Essays are best done on paper. You dont have spell check, grammar check and the ability to chop and paste in an exam.
I suppose you could do research on the computers, but then, when the school has three full class computer rooms, why bother with laptops just for research when you could go to those rooms?
Computers break down, computers stop working. Viruses, Infections, Spyware, Trojans, Adware (hey that spells Vista!). One student I know had at least 5 new hard drives, in 2 years. And each one interrupted his schoolwork in some way. I had one new one myself.
The benefits of computers in the classroom do not outweigh the distractions and effects of them.
If it aint broke, dont fix it. It's easier, and more productive to learn by paper and pen. I find i take more in if I write it by hand too.
put simply. it doesnt work
phew... ok, rant over.
slightly more on topic: having a system with the things mentioned above would be terrible to maintain. It's extra work for teachers (they hate that), and it would need to be kept up to date. Curriculum changes. You couldnt share between different schools either, as many teach things differently. Online lessons? Man I have a text book! Chat sessions? I'd rather talk face to face, it's soo much quicker and effective. I know that my teachers are happy to field any questions, in or out of class time.
secondary rant over.....
ciao,

Ruby on Rails in Portal Applications?

how can i make use of Ruby on Rails for developing Portal interfaces

Hello Rohit,
a Ruby Application can be included into the Portal like any other external application using an URL-iView. If you have to logon to a ABAP Backend system in your Ruby Application you can try to use Logon Tickets as I've used in my Blog: <a href="/people/gregor.wolf3/blog/2006/09/30/single-sign-on-with-external-id-implemented-in-ruby Sign On with External ID implemented in Ruby</a>. You only need the part starting with Variable "rfc2". The ticket is a cookie sent by the client Browser if you are using the same subdomain.

Ruby on rails in archlinux bootstrap instalation

I have 6 servers that were migrated from CentOS to Archlinux. They run apache with ruby on rails. The installations were done via bootstrap with one exception. In all they had to have them installed via bootstrap error "invalid byte sequence in US-ASCII ". I created a debug to see what is happening because the whole application runs on UTF-8. I noticed that the servers installed with bootstrap changed the environment variables, these changes occurred with the application running.

Ruby on Rails

I tried to follow the Ruby on Rails example post by Apple but it simply didn't work. I got the server started but the SQL migration didn't work. Has anybody made this work or been able to get through the "tutorial?"

Thanks. It is hard to describe exactly what doesn't work, but I will try. I get to the point in the tutorial where the server is up and running, I get Textmate running, but I keep having trouble with MySQL. I have installed MySQL 5.0.5 but at one point I got a screen that said I was using SQLite3. I think that came with some Apple package. I don't know how to "look at that particular section of the config/database.yml file." Nor how to modify it per the tutorial. "mysqladmin" commands generate an error message saying they can't be found. It seems that I have environmental issues. Of course, the "golden path installation guide," Locomotive, has been removed from circulation. So, I think that the tutorial assumes things will be done for you by installing Locomotive and that can't happen. I can't even get to the sample application.
Does this help in analyzing my problem?

Ruby on Rails Concurrent program registration in EBS 11i

hi everyone
I'm trying to see if it is possible to register a Ruby on Rails concurrent program in Oracle E-business Suite 11i applications. We have Ruby on the Rail program we are using to create a GL Daily Rates file into one of our Custom top directory. Our intention is to create a request set that includes this Ruby on Rails program and SQL*Loader program that loads the data into staging table before data is uploaded to the GL_Daily_Rates_Interface.
I have seen that the execution method for Ruby on Rails does not exist in 11i and have tried to use perl but without success.
Any help will be much appreciated.
Thanks in advance.

Just wanted to let you know that I created a Ruby on Rails page on the

As always, please feel free to comment and edit the wiki.

Hi,
It is a really nice idea. Maybe the page ought to serve as a hub for other articles.
A couple of comments on sharing medias:
* I have not been very happy with upnp. I used it for a while when I had a Synology NAS, but the fact that it seemed to rely on some kind of index made it less attractive. Samba has treated me nice; it always works (as oppose to "real" Windows shares which is a drag to setup). I use samba for sharing videos and pictures to XMBC4Xbox.
* For streaming live audio output, i.e. what is playing *right now* on my laptop to my stero, I have found a combo of icecast, pulseaudio and gstream to work nice. For serving static audio files I use squeezeboxserver. Had I used a Sonos sound system I would have used Samba again.
* For PS3, which is a somewhat limited device, there is a nice java application that takes care of everything.
* What I really miss is some way to preserve metatags when downloading video podcasts. To me it does not matter much at the moment as xbmc does not support local rss feeds. . .
I could add some comments on some of the above if you think it fits into your article.

Ruby on Rails environment

I have tried the Apple tutorial and Adam Blackbourne's book and website and still cannot get a functional environment started so that I can develop using Ruby on Rails. I get Ruby installed, Textmate installed, and then seem to get bogged down with Textmate and sql. I seem not to have mysql properly installed but I can't figure out what's wrong. Both these sources above refer to some great package call Locomotive that is "the golden path..." but it has been withdrawn by its author. Any ideas on how to proceed? What sources are available?

Hi,
I'm not sure what your stated problem is here? It seems you are describing problems with Ruby on Rails on Leopard and coincidentally with mysql based on the Apple tutorial; are these one problem or two? Please note that the tutorial is describing running mysql on server which is part of the 10.5 server package.
I have been running Rails 2.0.2 on Leopard client which I loaded following the tutorial (once I loaded Xcode 3 on the client as well). Since Rails 2.0 comes with sqlite3 as its default database, you can be up and running on 10.5 client in short order and save your mysql for deployment. In my case I also have 10.5 Server and have been testing with Rails and reverse proxies while operating in development mode (with sqlite3). When I start porting over to Server, mysql is a service on server and has a unique configuration. So the tutorial may not be applicable if you are using it with a mysql standard type install. You can read about the server install environment of mysql at
http://docs.info.apple.com/article.html?path=ServerAdmin/10.5/en/c6ws25.html
Actually, Ruby on Rails 2.0.2, TextMate and Ruby-Debug form a great environment for development. Not quite an IDE on 10.5 but almost there.
Hope this helps,
Harry
