I am studying in the "Quick Practice Guide". Currently, we are creating a task management application for Chapter4.
I want to be able to use task management without logging in.
I want to check if the user is logged in with a filter that is processed before the action written by the task management function. If the user is not logged in, I want to redirect to the login screen and make the task management function practically unavailable.
I'm in trouble without knowing why login was defined.
・ Addbefore_action: login_requiedtoapp/controllers/application_controller.rb
skip_before_action: login_requiredwas added to・app/controllers/sessions_controller.rb, I encountered the following error.
ArgumentError
Before process_action callback: login_required has not been defined
class SessionsControllerapplication_controller.rb
class ApplicationController
app/controllers/sessions_controller.rb
Class SessionsControllerskip_before_action: login_required
skip_before_action: login_required, raise: falsewas changed to a redirect loop.
Please describe what you tried for the problem here.
Supplemental information (FW/tool version etc.)ruby 2.6.3 rails 2.5.3
Please include more detailed information here.

I'm in trouble without knowing why login was defined.
But
: login_required has not been defined
: Login_required has not yet been defined
It is an error.
def Please define login_required.
