Rails 2.3-style plugins and deprecation warnings running task in Heroku
Are you using Heroku?
Heroku will inject plugins in Rails 3.x applications .. To avoid this injection in Rails 3, include the rails_12factor gem in your application. (Heroku Ruby Support 2013-10-26)
The rails_12factor gem is also required in rails 4.
If this gem is not present in your application, you will receive a warning while deploying, and your assets and logs will not be functional. (Rails 4 on Heroku 2013-10-26)
As recently as 2013-08, heroku always injected plugins in rails 3 apps, even apps with the recommended gems. This was an issue with the ruby buildpack, and was fixed by PR 11, merged on 2013-08-06.
You can try
::ActiveSupport::Deprecation.silenced = truein your production.rb since it's just noise.
in config/environment.rb add:
ActiveSupport::Deprecation.silenced = true before initializing rails, like so:
# Load the rails application require File.expand_path('../application', __FILE__)ActiveSupport::Deprecation.silenced = true # Initialize the rails application MyApp::Application.initialize!Similarly to disable warnings in rake tasks insert the silencing config near the top of your Rakefile:
# Load the rails application require File.expand_path('../application', __FILE__)ActiveSupport::Deprecation.silenced = true # Initialize the rails application MyApp::Application.initialize!You can optionally wrap this in a block to only silence in production:
if ENV['RAILS_ENV'] == "production" ActiveSupport::Deprecation.silenced = trueend
