Ruby on rails 嵌套注释，错误。轨道4。很抱歉，出了点问题

所以，我处于环境模式。我的错误是：很抱歉，出了点问题。 我的意见：

def create
  @post = Post.find(params[:post_id])
  @user = current_user
  @comment.user_id = @user.id
  @comment = @post.comments.create(params[:comment].permit(:body))
  redirect_to @post
end

Show file posts/Show您应该检查站点/服务器错误日志以获取特定的错误消息。最有可能的是一个你不期望的值是nil。你能在helper表格中使用这样的括号吗？我想它应该是括号。另外，我认为您可能正在寻找这个-devlog:Started GET/posts/18 for 127.0.0.1 at 20140326 Process PostsControllershow as HTML参数：{id=>18}[1m[35mUser Load 0.5ms[0m SELECT users.*FROM users WHERE.id=1 ORDER BY users.id ASC LIMIT 1[1m[36mPost Load 0.3ms[0m[1m SELECT posts.]FROM posts.id=？LIMIT 1[0m[[id，18][1m[35mUser加载0.3ms[0m选择用户。*来自用户，其中users.id=？限制1[[id，1]]Rendered comments/_form.html.erb 7ms Rendered posts/show.html.erb in layouts/application 12ms在29ms中完成500个内部服务器错误还尝试了：接受\u嵌套的\u属性\u for:posts controller中的注释。没有效果。请共享您的posts/show.html.erb文件
