Jestem początkujący w ROR i na samym początkiem natknołem się na taki problem.
wygenerowałem controler i model dla bazy która ma tylko 2 pola ( id i posts )
w controlerze zdefionowałem tylko scaffold
class BlogController < ApplicationController
scaffold :post
end
kiedy odwołuje się do aplikacji http://192.168.0.1:3000/blog/ otrzymuje taki błąd
NoMethodError in BlogController#index
undefined method `paginate’ for #BlogController:0xb733be10
RAILS_ROOT: /home/www/brablog
