How Pundit passes current_user to authorize method?

Question

Pundit's authorize takes 3 arguments, but in the controller you just need to pass 2, current_user is passed automatically. How is current_user passed? I looked at Pundit's code, but couldn't figure it out.

Answer 1

From pundit readme:

The first argument is a user. In your controller, Pundit will call the current_user method to retrieve what to send into this argument

From pundit.rb file:

def pundit_user
  current_user
end
