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

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!

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

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*.

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

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

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

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