Hi,I am trying to create a user autentication system. Normally the
user autentication system works fine but now i want to include the
login and logout in the header of the application. so that u can login
and logout in any part of the application
this it the weird part of the problem. let's say i am in articles/
search then i login and logout there is no problem. but when i go to
articles/show i get

logging out inside :show as well and everything works.
