Question

所以我有这个破坏控制器：

def destroy
    Post.find(params[:id]).destroy
    flash[:success] = "Post Deleted."
    redirect_to users_url
  end

这个观点：

<% @posts.each do |i| %>
<li>
This post was created at: <%= i.created_at %></br>
Contents of the post: <%= i.content %>
<%= link_to "Delete this post", @post, method: :delete, class: "black", data: { confirm: "You sure?" } %>
</li>
<% end %>
<% end %>

现在当我进行删除时，它只是将我重定向到我在控制器中创建的页面，就是这样。在服务器日志中，我得到了：

我在这里缺少什么？

Answer 1

您有一个前置过滤器，用于检查您当前的用户是否为admin_user。您的日志显示您的当前用户不是，因此在您执行destroy操作之前，您将被重定向。

此外，您应该发送带有重定向的Flash消息。 See this post for more info

 redirect_to users_url, success: "Post Deleted."
