コメントの更新を処理しようとしています。これは PUT リクエストであると確信していますが、次のような GET コマンドを取得しているようです。
[GET] "/books/10/snippets/24" に一致するルートはありません
スニペット用のコントローラーは次のとおりです。
class SnippetsController < ApplicationController
before_filter :authenticate_user!, only: [:create]
before_filter :find_book
def create
@snippet = @book.snippets.create!(params[:snippet])
redirect_to @book
end
def edit
@snippet = @book.snippets.find(params[:id])
end
def update
@snippet = @book.snippets.find(params[:id])
respond_to do |format|
if @snippet.update_attributes(params[:book])
format.html { redirect_to [@book, @snippet], notice: 'Comment was successfully updated.' }
else
format.html { render action: "edit" }
end
end
end
private
def find_book
@book = Book.find(params[:book_id])
end
end
これが私のフォームです。最初に _form.html.erb
<%= form_for([@book, @snippet]) do |f| %>
<% if @snippet.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@snippet.errors.count, "error") %> prohibited this comment from being saved:</h2>
<ul>
<% @snippet.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.text_field :body %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
次に、私の理解から、親（本）に関連してスニペットを作成または表示するためにのみ使用される私のスニペット部分。
<%= div_for snippet do %>
<p>
<strong>
Posted <%= time_ago_in_words(snippet.created_at) %> ago
</strong>
<br/>
<%= snippet.body %>
<br/>
<%= link_to 'Edit', edit_book_snippet_path(@book, snippet) %> |
<%= link_to 'Back', books_path %>
</p>
<% end %>
ローカルホストから取得したルートは次のとおりです。
> http://localhost:3000/books/10/snippets/24
ここに私のレーキルートがあります：

# The priority is based upon order of creation:

# Sample of regular route:
# match 'products/:id' => 'catalog#view'
# Keep in mind you can assign values other than :controller and :action
# Sample of named route:
# match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase
# This route can be invoked with purchase_url(:id => product.id)
# Sample resource route (maps HTTP verbs to controller actions automatically):
# resources :products
# Sample resource route with options:
# resources :products do
# member do
# get 'short'
# post 'toggle'
# end
#
# collection do
# get 'sold'
# end
# end
# Sample resource route with sub-resources:
# resources :products do
# resources :comments, :sales
# resource :seller
# end
# Sample resource route with more complex sub-resources
# resources :products do
# resources :comments
# resources :sales do
# get 'recent', :on => :collection
# end
# end
# Sample resource route within a namespace:
# namespace :admin do
# # Directs /admin/products/* to Admin::ProductsController
# # (app/controllers/admin/products_controller.rb)
# resources :products
# end
# You can have the root of your site routed with "root"
# just remember to delete public/index.html.
# root :to => 'welcome#index'
# See how all your routes lay out with "rake routes"
# This is a legacy wild controller route that's not recommended for RESTful applications.
# Note: This route will make all actions in every controller accessible via GET requests.
# match ':controller(/:action(/:id))(.:format)'

ヘルプは本当にありがたいです。ネストされたコメントを更新する方法についてのアイデアも役立ちます。私は編集段階に入ることができますが、それはネットのトロールから「def update」によって処理されるフォームの送信にすぎません。
ご協力いただきありがとうございます。
