My Rails development IDE is Aptana Studio 3.0.5, running on Windows.
The applications runs on Apache + ModRails (Phusion Passenger) on a separate CentOS Linux machine. I have both Rails 2.x and 3.x applications.
I would like to be able to use the debugger in Aptana Studio (connect to the running application remotely). There are apparently some provisions for this, but I was unable to figure out what I need on the server side (in my Rails application configuration)
I've tried this:
Using Rack::Debug: It creates only unix socket, cannot be connected remotely.
Using ruby-debug directly:
I added this to my /config/environments/development.rb:
if File.exists?(File.join(RAILS_ROOT,'tmp', 'debug.txt'))
require 'ruby-debug'
Debugger.wait_connection = true
Debugger.start_remote("real.hostname", 5000, 5001)
File.delete(File.join(RAILS_ROOT,'tmp', 'debug.txt'))
end
Sprinking my code with debugger statements stop the execution, but I cannot connect to this instance from Aptana, not to port 5000 and not port 5001 (and I don't understand why I need two ports there).
Also, this method would be rather slow and too convoluted even if it worked, I'd like to have a more "integrated" debugging. Is it possible at all?
The old steps for Netbeans are relatively close since Aptana/RadRails and Netbeans share the same debugger core: http://blogs.oracle.com/martink/entry/remote_debugging_debug_whatever_ruby
Basically, run the ruby app using rdebug-ide -p 7000 (or whatever port you want), then inside the IDE, go to Run > Debug configurations. On the left hand side, select "Remote Ruby Debug Session" and then add a new configuration there (the plus icon above the list). Enter the proper host IP/name and port you entered on the command line.

I am using Aptana Studio 3 for development of ROR apps. I used run server command and it showed you can access your app on {http//0.0.0.0:3000/}, but when I try to access this URL, it tells me to check your Internet connection. I tried several other ports also but it is not working. I have created/modified the files necessary and migrated the database successfully too. Appreciate any help in running the app over the browser. I am currently using WeBrick Server.
so, in your title you say "on server". what does that mean? when you are running it on a different machine than your own, you need to use the address of that machine or it's domain name. keep in mind that firewall rules might prevent any connection to that server.
when you are ON the machine, via ssh for example, you can try calling the then "local" rails instance with curl http://localhost:3000/ to verify that it is running.
I am new to Ruby on Rails, but I managed to install it using the RailsInstaller and I am using Aptana Studio 3 as a text editor. I am on a Windows 7 x64.
Last week I managed to create a simple Hello world project, and it worked as it should when starting and stopping the rails server. To start the server I used the command rails server and to stop it I used CTRL+C.
Somehow, this week, when I'm trying to start the server it says "A server is already running". But, when I go to the correct page in a web browser it doesn't work. I get the error "Google Chrome could not connect to localhost:3010". So, this makes it seem like the server is not working, even though it supposedly is running.
So, I then try to stop the server from running, but CTRL+C doesn't seem to do anything. It doesn't give any kind of message at all when I input that, it just skips to a new line in the terminal window.
the standard port is 3000.
You can kill the server in the task manager and start it from new..
There is probably a rails process still running but bugged out/crashed. Try looking at the processes in the windows task manager to for a rails process, and cancel it. Additionally you can start a rails process on a different port with rails server -p PORT
I'm very new with Rails and I've installed Vagrant to run the Rails server. I've started the server and am able to load localhost:3000, now I don't know where to go. The command line is blank and I read that I should type in "script/console", but all I can really do is ctrl-C or -d.
When I tried to run Vagrant in a separate Window with "vagrant up" it says I need to do "Vagrant init"
Where do I go from here so that I can start going through my tutorials/start developing?
This screencast from RailsCasts should get you started. Some of the suggestions are a bit out-dated but by reading the show notes and comments, you should be able to get up and running. From there you can modify.
While getting Rails set up initially with Vagrant will be work, it's an incredibly handy tool to have experience with. It becomes even more useful when you incorporate a provisioning tool like Puppet.
In your terminal if you are running the webrick server via rails server you either need to background it or open a new terminal to get your shell prompt back. If you ctrl-C out of it you will kill the server. Keep in mind, the webrick server should only be used for local development. It's not a production level web server. See the Rails Getting Started guide for more details.
If you are going to run your rails server in a Vagrant VM, you'll need to configure the port forward in your Vagrantfile so you can access from your host machine.
config.vm.forward_port 3000, 9080
There error you are seeing would be from you running vagrant up in a directory that doesn't contain a Vagrantfile.
I installed Ubuntu, GlassFish web server, installed JRuby on Rails using GlassFish's admin tools, deployed my application from .war archive. The problem is only - when I attempt to run this web application nothing happens. GlassFish isn't listening on port 8080 as promised. The GlassFish administration web console listens on port 4848 and works fine. What to do to pair GlassFish and JRuby on Rails the correct way, remembering that it isn't a separate JRuby installation?
Update: it seems that this problem lies somewhere around access rights because I can deploy an application through
sudo ./asadmin deploy
but can not do the same through web console. The output is as if the application has been deployed, without any error messages (web interface shows the presence of application, domain folder contains my application's file/folder structure), but something in server's internals isn't bound to application.
I didn't think much and applied quick and dirty solution: set "777" access rights to /home/glassfish and all its contents. It helped.
When I try to run InstantRails 2.0 under Vista, which I've extracted to C:\InstantRails, I get the following error:
Either Apache or MySQL cannot run because another program is using its port.
What do I do here? MySQL server is installed fine.
InstantRails will tell you in its console exactly which one can't run with its traffic lights. It's most likely a clash between Apache and Vista's built in web server (IIS) on port 80. I'd go open up the Services list and turn IIS (may be called 'HTTP Web server' or something similar) off.
And, to be honest, as useful as InstantRails was, it's not actively maintained. Bitnami's RubyStack is a fair substitute although it's larger, takes longer to install, and doesn't have the nice pointy-clicky interface for starting mongrel instances that InstantRails (RIP) did.
