Whenever: Capistrano/Bundler/Vendored Whenever - "Uninitialized Constant Whenever::JobList::Rails"

Created on 31 May 2011  ·  7Comments  ·  Source: javan/whenever

I have seen similar errors to this marked as resolved in the current version, so I thought I would post as I am using the current version and am still seeing issues with this

Deploy.rb

set :whenever_command, "bundle exec whenever"
set :whenever_environment, defer { stage }
require "whenever/capistrano"

Am I doing something wrong or is this a bug with Whenever?

Thanks! Ended up doing this as the completed line in case anyone else is looking for the same:

set :output, File.join(Whenever.path, "log", "cron.log")

Does your schedule.rb file call a method on Rails? Keep in mind whenever doesn't load your Rails env.

Yes :) I am trying to make certain cron tasks only run in certain environments, so I place chunks of code in "if Rails.env == 'staging'" etc…

Is there a supported way of doing this :)

Since you're --set environment=staging you can can use the environment variable in your schedule.rb: if environment == 'staging'

worked great. Thanks for the lightspeed support.

Similarly, how can I do the same in schedule.rb without referencing the Rails object?

set :output, Rails.root.join('log', 'cron.log')

Edit: I should mention that I don't even know what the default value is since it doesn't seem to be mentioned anywhere...perhaps I don't even need to specify an :output value.

You can use Whenever.path to determine the root directory.
