Hello everyone, This is the first time I want to use ActiveRecord outside Rails. This is my (simplified) code: ActiveRecord::Base.establish_connection( :adapter => 'mysql', :host => 'localhost', :username => 'username', :password => 'password', :database => 'database') class Rate < ActiveRecord::Base end r = Rate.find(:first) r.value = new_rate r.save! This works fine, but I was wondering if I have to close any database connections at the end of my script (by using remove_connection??)? Or is does AR take care of this automatically? Thanks in advance. Mischa.

When I execute the script from the command line it runs flawlessly, but when it's executed from cron I get the following error in my script: no such file to load -- mysql The line where the error occurs is: r = Rate.find(:first) My crontab looks like this: * * * * * /usr/local/bin/ruby /home/mischa/railsapps/aexscript/periodic/get_rate.rb production >> /home/mischa/railsapps/aexscript/periodic/get_rate.log So I use full path to everything. Any ideas??

I got it working. It turned out the mysql gem wasn't in the expected gem folder. Why everything works smoothly from the command line is beyond me, but it works :-)
