Rails 3 runner with .war deployment

dubstep · October 11, 2011, 2:21am

Hi,

I’m trying to figure out how to run a ‘rails runner’-type task (for a
cron job) with a .war-file deployment of a rails 3 app?

Perhaps something like this:

export RAILS_ENV=production
export
CLASSPATH=/opt/tomcat7/webapps/ROOT/WEB-INF/lib/jruby-core-1.6.3.jar:/opt/tomcat7/webapps/ROOT/WEB-INF/lib/jruby-rack-1.0.9.jar:/opt/tomcat7/webapps/ROOT/WEB-INF/lib/jruby-stdlib-1.6.3.jar
export GEM_PATH=/opt/tomcat7/webapps/ROOT/WEB-INF/gems
java org.jruby.Main -w -S rails runner “MyModel.run_nightly_report”

?

Thanks,

Brian

Not exactly what you’re looking for, but I’ve been using the following
script to run the Rails console from inside an exploded .war. I’m sure
it would something similar for the rails runner.

https://gist.github.com/lenny/1278231

gistfile1.rb

#!/usr/bin/env jruby

raise "Must specify CATALINA_HOME" unless ENV['CATALINA_HOME']

ENV['GEM_HOME'] ||= File.expand_path('../../gems', __FILE__)

require File.expand_path('../../../META-INF/init', __FILE__)

# expected by rails/commands
APP_PATH = File.expand_path('../../config/application',  __FILE__)

From inside a deployed WEB-INF directory I run script/tomcat-console

Actually, the gist above works for all rails commands if you just remove
the line ARGV.unshift(‘c’) line and run it like:

cd WEB-INF
script/tomcat-rails console
script/tomcat-rails runner myscript.rb
