[Rails] Directing command output to a view
Hi all, Ive recently designed a system that is started from the command line. ie. /usr/local/bin/system.rb The system is a long running task that outputs messages via "puts" to the shell as its being executed. I need to run this command from a rails application so that 1) it doesnt block .ie user gets a "please wait" screen 2) and more importantly I want the output of the command sent in real-time or near real-time to the view, under the "please wait" message. And when the command exits, the user is redirected to another view. Any ideas whats the best way to do this?

[Rails] JRuby/glassfish v3 logging problem
Hi all, Ive just tried to run my app with jruby and glassfish. It seems to work mostly fine, except one weird thing. Glassfish turns over log/development.log when its size hits 1.9MB, renames it to something like development.log_2009-04-20T13-57-30 but never creates a fresh development.log and at that moment the glassfish server just stops working. What im doing is basically cd into my application's RAILS_ROOT, and execute glassfish_rails. My OS is FreeBSD 7.2 Any ideas? -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I'm aware of different solutions to run a background job. However, the problem is how to make 4 background jobs MPSAFE, all of them working on the same Hash. Any ideas?

[Rails] Background tasks + multi processing
Hi all, Ive recently been trying to figure out a way to make a long running background task scale accross all CPUs in Ruby on Rails, since multi-processing (not multi-threading) seems like the way to go. A theoretical example would be: # code in controller def do_something @mydata = Hash.new # Start 4 background processes # and start adding data to @mydata # Page loads while the processes are working, displaying # something like "We are currently processing your data" end Question is how to handle reading/writing to @mydata safely because 4 processes would be trying to read/write to it? What is the best way to approach this problem?

[Rails] Re: Passenger caching in development mode, wtf?
Ok i resolved it, after hours of trying to figure it out, i noticed that the cause is having config.threadsafe! enabled in development mode. For some reason it causes caching to get enabled. This option should be documented better.

[Rails] Re: Passenger caching in development mode, wtf?
This makes no difference. The problem is with mongrel is that I need the devel applications to be accessible even when im not developing, ie. client review. And id need to make a start up script in case i reboot the server to make all the mongrels start up. Its just hassle. dispatch.cgi/fcgi was ideal for simple setup in development mode where speed usually doesnt matter.

[Rails] Passenger caching in development mode, wtf?
Hi all, I updated an application to Rails 2.3.2(and ruby 1.9.1) and installed Passenger, after learning that it turns production mode on by default, i changed that to development mode. Logs are correctly being saved to development.log so i should definately be in development mode, right? Well NO! Any change to my code has to be followed by a restart of the application due to some caching that I dont want. Now that they are removing CGI support too, just how the hell am I supposed to be making a website in development mode without having to restart 500 times a day Thanks Petr -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Mongrel and application's public path problem
Hi all, Im trying to fix a path problem. My app was developed while using fastcgi. When I did FileUtils.mkdir it created a new directory under the public directory in my application. Now in production we use mongrel + mongrel_cluster, BUT the directory is created in the application's directory in "/usr/websites/myapp" instead of "/usr/websites/myapp/public". What do I have to do to fix this?

[Rails] Re: Multi-Site sessions
No its not because one box cannot handle the load, but because certain activities the users would be doing are best done on a separate high-performance box(other than the normal web-server). -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

[Rails] Multi-Site sessions
Hi all, Im developing an application that runs on multiple physical boxes (and thus different hostnames). Both of the boxes will run the same application (connecting to a shared postgres server). What I need is when someone logs in on box 1 (ie. box1.domain.com), and then traverses via a link to box 2 (ie. box2.domain.com), he or she will not have to login again. How can I do this?
