FilterDecrufter is a little utility for cleaning up before_filters.
Suppose you have a Rails controller with a before_filter:
before_filter :load_widget, :only => [:show, :frobnicate]
If you've deleted the frobnicate action, Rails won't complain. But FilterDecrufter will!
Add it to your Gemfile in the development group:
# In your Gemfile gem 'filter_decrufter'
Run the task!
$ bundle exec rake filter_decrufter:check Api::V1::WidgetsController before_filter 'find_widget' has an :only constraint with a non-existent action name 'show' EmployeesController after_filter 'set_name' has an :only constraint with a non-existent action name 'frobnicate'
Tested with Rails 3.2, 4.0, 4.1 and 4.2.
