How to pass control from one controller to other in Rails? - ruby-on-rails

Question

I have one controller called Page_controller and another one called Categories_controller. Now whenever the home method in the Page_controller is called I wanna be redirected to the a´categories controller, as I wanna control the Category view from that moment on. This is what I have written:
class PagesController < ApplicationController
def home
#categories = Category.all
redirect_to category_url(#category)
end
end
but I get an error when I open the server saying:
undefined method `category_url' for #<PagesController:0x000000000b24ce20>
for the line:
redirect_to category_url(#category)
Does anyone know how I could pass control from one controller to the other? I am really desperate so apreciate any help you can provide
EDIT: this is my routes.rb file:
Rails.application.routes.draw do
resources :comments
#resources :categories
root to: 'pages#home'
get 'index', to: 'controller_category#index'
devise_for :users
end
And the routes printed out from the console:
C:\Users\andri\Desktop\proj>bundle exec rake routes

Uncomment this line in your routes.rb file:
#resources :categories
That will define a set of routes for categories, which will provide you with methods such as category_url(category).
You'll also need a CategoriesController, otherwise your next problem will be that the redirect produces an error (no such controller). And you'll need to implement CategoriesController#show.
