Ruby on rails コメント削除機能実装中エラー

Question

コメント削除機能実装中なのですがルーティングでエラーが出てしまいました。
解決方法が分からないので教えて頂きたいです。

Rails.application.routes.draw do

  devise_for :users
  get "login" => "users#login_form"


  post "login" => "users#login"
  post "logout" => "users#logout"


  post "users/:id/update" => "users#update"
  get "users/:id/edit" => "users#edit"
  post "users/create" => "users#create"
  get "singnup" => "users#new"
  get "users/index" => "users#index"
  get "users/:id" => "users#show", as: :user

  get "posts/index" => "posts#index"
  get "posts/new" => "posts#new"
  get "posts/:id" => "posts#show", as: :post

  resources :comments, only: [:create,:destroy]


  post "posts/create" => "posts#create"

  get "posts/:id/edit" => "posts#edit"

  post "posts/:id/update" => "posts#update"
  post "posts/:id/destroy" => "posts#destroy"
  get "/" => "home#top"
  get "about" => "home#about"

end

Answer 1

redirect_to("/posts/index")に変えたらエラーは無くなりましたがコメントがきちんと削除されてないのと削除の表示がすごいたくさん出てきました。

Answer 2

get "posts/index" => "posts#index"

って書かれているので http://localhost:3000/posts/index ってURLにアクセスしたら動きますかね？

または

  get "posts/index" => "posts#index"
  get "posts/new" => "posts#new"
  get "posts/:id" => "posts#show", as: :post
  post "posts/create" => "posts#create"
  get "posts/:id/edit" => "posts#edit"
  post "posts/:id/update" => "posts#update"
  post "posts/:id/destroy" => "posts#destroy"

このpostsとなっているものはまとめて

resources :posts

と書くことが出来そうなので、書き換えたら、 http://localhost:3000/posts でアクセスできるようになるかもです。
posts_controller.rbがちゃんと書いてあることが前提ですが。
