Running Thor in Rails production environment

Question

I want to run some thor task on rails 3 in production, but I do not know how to set it up. The following code did not work

class CheckData < Thor
  require File.expand_path('config/environment.rb')
end

Answer 1

Setting the RAILS_ENV environment variable to 'production' right above therequirestatement should work. I used conditional assignment here to default the environment to 'production' if the environment variable is not set ahead of time.

class CheckData < Thor
  ENV['RAILS_ENV'] ||= 'production'
  require File.expand_path('config/environment.rb')
end

If you are running it as a Thor task from the command-line you can then set the environment variable before running and thus override the default assignment:

export RAILS_ENV=test; thor check_data

See Configuring Rails Applications Rails Environment Settings from RailsGuides for more environment variables.
