Я получаю следующую ошибку, когда нажимаю ссылку выхода, хотя метод, кажется, существует.
NameError in SessionsController#destroy
undefined local variable or method `sign_out' for #<SessionsController:0x007f87c8ecd8d8>
Вот мой код, контроллер сеансов
class SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:session][:email].downcase)
if user && user.authenticate(params[:session][:password])
# Sign the user in and redirect to the user's show page.
else
flash.now[:error] = 'Invalid email/password combination' # Not quite right!
render 'new'
end
end
def destroy
sign_out
redirect_to root_url
end
end
Помощник по сеансам
module SessionsHelper
def sign_in(user)
cookies.permanent[:remember_token] = user.remember_token
self.current_user = user
end
def current_user=(user)
@current_user = user
end
def current_user
@current_user ||= User.find_by_remember_token(cookies[:remember_token])
end
def signed_in?
!current_user.nil?
end
def sign_out
self.current_user = nil
cookies.delete(:remember_token)end
end
