Well done!

When you visit the URL /login, the browser makes a GET request for the URL. This request hits the Sessions controller’s new action, which returns a view displaying the login page.
In the login form, we use form_for(:session, url: login_path) do |f|. This refers to the name of the resource and corresponding URL. In the signup form, we used form_for(@user) do |f| since we had a User model. For the login form, we don’t have a Session model, so we refer to the parameters above.

Instructions

Next, let’s take in data submitted through the form and log the user in by starting a new session.

In the routes file, create a route that maps the URL ‘/login’ to the Sessions controller’s create action.

post 'login' => 'sessions#create'

In the Sessions controller, add the create action

def create
  @user = User.find_by_email(params[:session][:email])
  if @user && @user.authenticate(params[:session][:password])
    session[:user_id] = @user.id
    redirect_to '/'
  else
    redirect_to 'login'
  end 
end

Visit http://localhost:8000/login and log in with your email and password.
