Well, I guess I''m successful because within a month of getting my very first application online (and it''s barely functional) I now have to get a second one up pretty quickly. Basically, I have a rails application "myFirstApp", and a hostname www.myfirstapp.com. Now I have a second rails app "mySecondRailsApp" and I need www.mysecondapp.com to peacefully

since webrick does not need to run with FCGI how do you get a rails app in FCGI mode to reload the controller (since it caches in production). Is it simply a restart of apache ? adam

What validator can I use in a model to ensure that my :username field is different from my :password field? I''ve tried validates_exclusion_of :password, :in =>:username but I get a rails error "an object with the method include? is required must be supplied as the :in option of the configuration hash" Thanks!

Have things running great on my local webrick. Decided to set things up on the local server and I get this error: Mysql::Error: Lost connection to MySQL server during query: SHOW FIELDS FROM users RAILS_ROOT: script/../config/.. So I thought it might be struggling to connect to mysql, so I tried with sockets instead of port 3306. No difference unfortunately. I can connect successfully to

I''m running a simple WEBrick server for a small rails website. I probably get less than 100 hits per hour. I just looked in /tmp on the server and there are over 10,000 ruby_sess.* temp files containing: " hash{" flashIC:''ActionController::Flash::FlashHash{: @used{ They''ve piled up so much that I can''t even rm -f ruby*. Bash complains

Hi all, Week 2 working with Ruby on Rails... I have a working app in development that is now throwing a generic, "Application error (Rails)" message in production. How do I deal with this so I can find more information about why the error is being thrown in production, but not in development? Thanks! -- Posted via http://www.ruby-forum.com/.

Hi, I''m considering migrating my site from php to RoR. I''ve installed RoR gone through the onlamp tutorials and made the recipie/todo list sample sites and tinkered with a few of my own. I understand the examples that use models and scaffolding to map tables, but I''m having a little trouble understanding how to handle general purpose queries. A few people have

I developed a small RoR app on my Ubuntu laptop and I just tried to migrate it to my "production" box which is Fedora FC3. I moved the entire rails app. I received this error when I tried to get the first page: [2005-11-17 15:36:00] INFO WEBrick::HTTPServer#start: pid=32546 port=3000 192.168.0.61 - - [17/Nov/2005:15:40:01 EST] "GET /freesql HTTP/1.1" 200 0 - ->

Is there anyone on this list running DamageControl on a Debian or a Windows system ? If so would you care to share how you accomplished this (details ... it''s all in the details) ? While I will still work through the problems I am encountering (it''s a great learning experience) I would still like to have a working instance of DamageControl to use in the meantime. I am

Hi Everyone, This is basically an FYI because I don''t think there is much that can be done about it. I work at a DoD lab and up until very recently I had no problems at all getting to rubyonrails.org. All week long I have not been able to visit the site and I finally gave up and submitted a trouble call to our network help desk. I was told that the site was in a class B range

I have been running a public MySQL server for over 4 years. The system was a 1GHz box with 256MB of RAM. MySQL puts each database into a seperate directory in a single "data" directory. Once the old system reached about 10K databases the connection times increased 10X or more. I attributed the speed problems to a possible filesystem limitation with a large number of files. That

I work with a MySQL installation containing several thousand databases. MySQL represents each database as a seperate sub-directory of the main MySQL data directory. As the number of databases increases it seems that the time to connect is increasing significantly and I believe this is probably due to the time necessary to search through the large number of directory entries. It has been

Greetings Everyone, A group in my office is designing/integrating what I would loosly label as an "embedded system". In that, it performs a dedicated task and is not a general purpose workstation or server. It operates in a harsh environment, particularly a questionable power environment and they are extremely concerned about inadvertent shutdown and recovery. They were totally

First of all I''d like to say thanks for all the great work everyone has put into scriptaculous, I''m having a lot of fun playing with the framework, and easily moving into Web 2.0 territory. I''ve just hit a snag on my project though. So here''s my code: ... var newEvent= "<div

I''m just getting started with GD2 and have successfully made a few dynamic PNGs. I need to make some fairly detailed line graphs on the fly and I know that GD2 is capable of what I want but I strongly suspect I''m reinventing the wheel badly. Are there gems or other projects that help creating complex charts? I''ve used GDChart in the distant past but I

Has anyone done any work on a "Resizeable" class they''d be willing to share?
