Question

I have two simple rake tasks — one that works and one that throws the following error:

rake aborted!
undefined method `my_config_param' for #<Rails::Application::Configuration:0x007ffba6b2d320>

Here are the tasks:

task :with_env => :environment do
  Rails.application.config.my_config_param #works
end

task :without_env do
  Rails.application.config.my_config_param #fails
end

It’s pretty clear why :without_env fails and I can easily wrap my call to Rails.application.config in a begin/rescue statement. But I would like to know if there’s a way I can tell a priori if the environment is missing so I can work around this more elegantly. Is there such a way? I’ve been unable to find one….

A colleague of mine noted that $rails_rake_task returns true if the rails env is loaded and false otherwise. This did the trick:

Rails.application.config.my_config_param if $rails_rake_task
