ruby on rails - Logout redirect error -

i having trouble logging user out , clearing sessions user. keep getting following error in rails server terminal window:

started delete "/logout" ::1 @ 2014-12-01 17:17:47 -0500  actioncontroller::routingerror (uninitialized constant sessoinscontroller): 

here controller sessions:

  class sessionscontroller < applicationcontroller     # sessions not active record model      def new     end      def create       user = user.find_by(email: params[:session][:email].downcase)       if user && user.authenticate(params[:session][:password])         log_in user         redirect_to user       else         # flash.now used when going homepage danger         # message not there anymore         # designed displaying flash on rendered pages         flash.now[:danger] = "invalid email/password combination"         render 'new'       end     end      # logs out current user, check session_helper details     def destroy       log_out       redirect_to root_url, notice: "you have logged out."     end    end 

here sessions helper: module sessionshelper

  # logs in given user   def log_in(user)     session[:user_id] = user.id   end    # returns current logged-in user (if any)   def current_user     @current_user ||= user.find_by(id: session[:user_id])   end    # returns true if user logged in, false otherwise   def logged_in?     !current_user.nil?   end    # logs out current user   def log_out     session.delete(:user_id)     @current_user = nil   end  end 

here routes.

get 'users/new' # these routes static_pages controller root               'static_pages#home' 'help'      => 'static_pages#help' 'about'     => 'static_pages#about' 'contact'   => 'static_pages#contact' 'signup'    => 'users#new' 'login'     => 'sessions#new' post 'login'    => 'sessions#create' delete 'logout' => 'sessoins#destroy' resources :users 

can please help. thank in advance.

as can see routes

logout delete /logout(.:format)         sessoins#destroy 

sessions spelled wrong

just make sure line correct:

delete 'logout' => 'sessions#destroy'
