目标是编辑相关文章的评论。Rails7.0.4.3
接收错误:

ActiveRecord::RecordNotFound in CommentsController#edit
Couldn't find Article with 'id'=#<Comment::ActiveRecord_Associations_CollectionProxy:0x00000001061950a8>

为'def edit' comments_controller.rb文件中的这一行。
我试着遵循这个nested edit path not workingActiveRecord::RecordNotFound in Controller#edit,但没有用。

comments_controller.rb

class CommentsController < ApplicationController

  def create
    @article = Article.find(params[:article_id])
    @comments = @article.comments.create(comment_params)
    redirect_to article_path(@article)
  end

  def destroy
    @article = Article.find(params[:article_id])
    @comment = @article.comments.find(params[:id])
    @comment.destroy
    redirect_to article_path(@article), status: :see_other
  end

  def edit
    @article = Article.find(params[:article_id])
    @comment = @article.comments.find(params[:id])
  end

  def update
    @article = Article.find(params[:article_id])
    @comment = @article.comments.find(params[:id])
    redirect_to article_path(@article)
  end

  private
  def comment_params
    params.require(:comment).permit(:commenter, :body)
  end
end

_comments.html.erb

<%# unless comment.archived? %>
  <p>
    <strong>Commenter:</strong>
    <%= comment.commenter %>
  </p>
  <p>
    <strong>Comment:</strong>
    <%= comment.body %>
  </p>

<%= link_to "Edit comment", edit_article_comment_path(@article.comments) %>

<p>
  <%= link_to "Destroy comment", [comment.article, comment], data: {
    turbo_method: :delete,
    turbo_confirm: "Are you sure?"
  } %>
</p>
<%# end %>

routes.rb

Rails.application.routes.draw do
  # Define your application routes per the DSL in https://guides.rubyonrails.org/routing.html
    root "articles#index"

    resources :articles do
      resources :comments
    end
end

controllers/comment.rb

class Comment < ApplicationRecord
  # include Visible

  belongs_to :article
end

你问题的关键在于错误本身,特别是-

'id'=#<Comment::ActiveRecord_Associations_CollectionProxy:0x00000001061950a8>

这告诉你rails正在搜索一个ID要编辑的记录,但是你提供了一个活动记录集合,它是来自你的has_many关联的许多记录的响应。
现在看看你的_comments.html.erb

<%= link_to "Edit comment", edit_article_comment_path(@article.comments) %>

您的路径是正确的,但是您的edit操作需要一个ID,而不是您通过@article.comments提供的注解集合。
现在我建议你循环遍历你的@article.comments,但是看起来你已经有了<%= comment.body %>,所以你只需要用comment替换你的path(ID)
