session.destroy in controller - ruby-on-rails

Question

I am trying to create a log out for my app and in my controller this piece of code is not working. Any solution would be helpful.
def destroy
#user = user.find(params[:id])
#user.destroy
end
This is my destroy method in my sessions controller(the fact that i am destroying my user in my sessions controller might be the problem)
class UsersController < ApplicationController
def new
end
def create
#user = User.create(password: params[:password],
email: params[:email],
firstname: params[:firstname],
lastname: params[:lastname])
redirect_to user_path(#user)
end
def show
#user = User.find(params[:id])
end
end
routes.rb:
Rails.application.routes.draw do
# Fubyonrails.org/routing.html
root :to => 'static#welcome'
resources :users, only: [:new, :create, :show]
resources :session, :only => [:new, :create, :destroy]
resources :studios
end
Routes file
uninitialized constant SessionController
is the error im getting

First, don't destroy your user. It deletes it from the database, you want them to be able to login again without creating a new user right?
You need to update your routes.rb file to be:
Rails.application.routes.draw do
# Fubyonrails.org/routing.html
root :to => 'static#welcome'
resources :users, only: [:new, :create, :show]
resources :sessions, :only => [:new, :create, :destroy] # changed to sessions
resources :studios
get 'logout' => 'sessions#destroy'
end
If you don't already, you need to define a SessionsController.
class SessionsController < ApplicationController
def destroy
# insert logic that actually logs them out, the below may already be enough
# for this purpose though
redirect_to root_url, notice: "Logged Out Successfully"
end
end
When the user clicks "Logout" it gets routed to the SessionsController#destroy action which redirects them to the root URL ('static#welcome')
There is more to it then that (i.e. the views and all that jazz) but this should be helpful enough
