我有一个名为Page_controller 的控制器和另一个名为Categories_controller 的控制器。现在每当Page_controller 中的home方法被调用时，我想被重定向到 a´categories 控制器，因为我想从那一刻起控制 Category 视图。这是我写的：
class PagesController < ApplicationController
def home
@categories = Category.all
redirect_to category_url(@category)
end
end
但是当我打开服务器时出现错误：
undefined method `category_url' for #<PagesController:0x000000000b24ce20>
对于该行：
redirect_to category_url(@category)
有谁知道我如何将控制权从一个控制器传递给另一个控制器？我真的很绝望，所以感谢你能提供的任何帮助
编辑：这是我的 routes.rb 文件：
Rails.application.routes.draw do
resources :comments
#resources :categories
root to: 'pages#home'
get 'index', to: 'controller_category#index'
devise_for :users
end
从控制台打印出来的路由：
C:\Users\andri\Desktop\proj>bundle exec rake routes
Prefix Verb URI Pattern Controller#Action
comments GET /comments(.:format) comments#index
POST /comments(.:format) comments#create
new_comment GET /comments/new(.:format) comments#new

PATCH /comments/:id(.:format) comments#update
PUT /comments/:id(.:format) comments#update
DELETE /comments/:id(.:format) comments#destroy
root GET / pages#home
index GET /index(.:format) controller_category#index
new_user_session GET /users/sign_in(.:format) devise/sessions#new
user_session POST /users/sign_in(.:format) devise/sessions#create

DELETE /users(.:format) devise/registrations#destroy
POST /users(.:format) devise/registrations#create
rails_service_blob GET /rails/active_storage/blobs/:signed_id/*filename(.:format) active_storage/blobs#show
rails_blob_representation GET /rails/active_storage/representations/:signed_blob_id/:variation_key/*filename(.:format) active_storage/representations#show
rails_disk_service GET /rails/active_storage/disk/:encoded_key/*filename(.:format) active_storage/disk#show
update_rails_disk_service PUT /rails/active_storage/disk/:encoded_token(.:format) active_storage/disk#update
rails_direct_uploads POST /rails/active_storage/direct_uploads(.:format) active_storage/direct_uploads#create
在你的 routes.rb 文件中取消注释这一行：
#resources :categories
这将为类别定义一组路由，这将为您提供诸如category_url(category).
您还需要一个 CategoriesController，否则您的下一个问题将是重定向产生错误（没有这样的控制器）。并且您需要实施CategoriesController#show.
