object.find fails in rakefile even though I'm including environment - ruby

Question

I've got a rakefile with a cron job in it that accesses one of my models and then does a search on my database. I'm including my environment and see to be able to create my object, but when I try to run the "find" method, I get this error:
rake aborted!

Answer 1

find is a method on an ActiveRecord class, and is not defined on an instance of an ActiveRecord object. So, to find the Feeder with ID of 1, you'd call Feeder.find(1).
The other thing I noticed is this: the line task :cron => :environment means that the environment is already being loaded--this includes rails/all, rubygems (you're using Rails 3, which uses Bundler), sqlite3 (assuming it's in your Gemfile and you've run bundle install to generate your Gemfile.lock, and all your models. Try removing all the requires lines and see if your rake task still executes.
