我想使用以下代码删除帖子： @H_403_2@<%= link_to 'Destroy',post,:method => :delete,:onclick => "return confirm('Are you sure you want to delete this post?')" %>

这不起作用……它只是将我重定向回帖子(帖子/：id}

但是,如果我使用以下代码,它的工作原理

@H_403_2@<%= button_to 'Destroy',method: :delete,:onclick => "return confirm('Are you sure you want to delete this post?')" %>

在这种情况下,是否可以使link_to表现为button_to？

编辑：破坏控制器功能

@H_403_2@def destroy @post = Post.find(params[:id]) @post.destroy respond_to do |format| format.html { redirect_to posts_url } format.json { head :no_content } end end

单击“销毁”按钮时记录：
