This is my routes.rb:

root to: 'user_session#new'
match '/user_sessions/new' => redirect('/user_session/new')
enter code here
controller :user_sessions do
get    'user_session/new'     => :new,  as: 'new_user_session'
get    'user_session/edit'    => :edit, as: 'edit_user_session'
get    'user_session'         => :show, as: 'user_session'
put    'user_session'         => :update
delete 'user_session'         => :destroy
post   'user_session'         => :create
end

And also put this to user_session_controller.rb

def destroy
current_user_session.destroy
redirect_to new_user_session_url
end
