logging - Rails 4 log all not found requests to the application -


what want output without error log file requests cause 404 ? or log such requests separately ?

you'll best hooking config.exceptions_app middleware hook:

sets exceptions application invoked showexception middleware when exception happens. defaults actiondispatch::publicexceptions.new(rails.public_path).

--

exceptions_app

having written gem this, , there nice demonstrations of how can used effectively, i'd recommend doing this:

#config/application.rb config.exceptions_app = ->(env) { applicationcontroller.action(:exception).call(env) }  #app/controllers/application_controller.rb class applicationcontroller < actioncontroller::base    def exception        # code here    end end

i'm not sure how you'd make conditional (i.e capturing "not found" exception), above starting point sure!
