routes.rbです

Rails.application.routes.draw do
  devise_for :users
  root to: "prototypes#index"
  resources :users, only: [:new, :edit, :update,]
  resources :prototypes, only: [:new, :create, :show, :edit, :update, :destroy,] do
    resources :comments, only: :create
  end

  devise_
scope :user do
    get '/users/sign_out' => 'devise/sessions#destroy'
  end

end

コントローラーrbです

class CommentsController < ApplicationController
  def create
    @comment = Comment.new(comment_params)
    if @comment.save
       redirect_to prototype_path
    else
        render :show
    end
  
  end

  private
  def comment_params
    params.require(:comment).permit(:text).merge(user_id: current_user.id, prototype_id: params[:prototype_id])
  end
end

edit.htmlです

<div class="main">
  <div class="inner">
    <div class="form__wrapper">
      <h2 class="page-heading">プロトタイプ編集</h2>
      <%# 部分テンプレートでフォームを表示する %>
      <%= render partial: "form" %>
    </div>
  </div>
</div>

部分テンプレートです

<%= form_with model: @prototype, local: true do |f|%>
  <div class="field">
    <%= f.label :title, "プロトタイプの名称" %><br />
    <%= f.text_field :title %>
  </div>

  <div class="field">
    <%= f.label :catct_copy, "キャッチコピー" %><br />
    <%= f.text_area :catct_copy, class: :form__text %>
  </div>

  <div class="field">
    <%= f.label :concept, "コンセプト" %><br />
    <%= f.text_area :concept, class: :form__text %>
  </div>

  <div class="field">
    <%= f.label :image, "プロトタイプの画像" %><br />
    <%= f.file_field :image %>
  </div>

  <div class="actions">
    <%= f.submit "保存する", class: :form__btn  %>
  </div>
<% end %>

Answer 1

app/controllers/comments_controller.rb が無いのでしょう
