Heroku上的Rails应用程序不会破坏元素

时间：2014-07-01 15:28:04

标签： ruby-on-rails ruby heroku deployment

我按照rails入门指南创建了一个简单的blog application。我在Heroku上部署了我的应用程序，除了销毁操作外，一切正常。我无法删除任何与他们相关的文章或评论。当我尝试删除文章时，我会被重定向到文章本身，当我尝试删除特定评论时，“您正在寻找的页面不存在。您可能输错了地址或页面可能已移动。”消息显示出来。

我的应用程序在本地完美运行（所有操作都按预期工作）所以我对这个问题感到有些困惑。 我已经在this问题上尝试了这些建议，但问题仍然存在。

索引视图（列出文章看起来像这样）

<h1>Listing articles</h1>
 <%= link_to 'New article', new_article_path %>
<table>
  <tr>
    <th>Title</th>
    <th>Text</th>
  </tr>

  <% @articles.each do |article| %>
    <tr>
      <td><%= article.title %></td>
      <td><%= article.text %></td>
      <td><%= link_to 'Show', article_path(article) %></td>
      <td><%= link_to 'Edit', edit_article_path(article) %></td>
      <td><%= link_to 'Destroy', article_path(article),
                    method: :delete, data: { confirm: 'Are you sure?' } %></td>
    </tr>
  <% end %>
</table>

评论视图如下：

<p>
  <strong>Commenter:</strong>
  <%= comment.commenter %>
</p>

<p>
  <strong>Comment:</strong>
  <%= comment.body %>
</p>
<p>
  <%= link_to 'Destroy Comment', [comment.article, comment],
               method: :delete,
               data: { confirm: 'Are you sure?' } %>
</p>

物品管理员：

class ArticlesController < ApplicationController
  http_basic_authenticate_with name: "dhh", password: "secret", except: [:index, :show]

  def new
    @article = Article.new
  end

  def create
    @article = Article.new(article_params)

    if @article.save
      redirect_to @article
    else
      render 'new'
    end


  end

  def show
    @article = Article.find(params[:id])
  end


  def index
    @articles = Article.all
  end

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

  def update
    @article = Article.find(params[:id])

    if @article.update(article_params)
      redirect_to @article
    else
      render 'edit'
    end
  end

  def destroy
    @article = Article.find(params[:id])
    @article.destroy

    redirect_to articles_path
  end

  private
  def article_params
    params.require(:article).permit(:title, :text)
  end
end

评论控制器

class CommentsController < ApplicationController
  http_basic_authenticate_with name: "dhh", password: "secret", only: :destroy

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

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

end

在我尝试删除文章后，这是“heroku日志”的输出：

除了404状态之外，我没有真正看到（或理解那个）任何错误的迹象。 再次感谢你们！
