【问题描述】：
我正在尝试开发一个留言簿应用程序，它存储用户名、国家和用户消息 sin mongodb，连接正常，我可以在数据库中提交这 3 个信息（用户名、国家和消息）。我的问题是将消息呈现到我的“guestbook.ejs”页面中。
如果有人能就我遇到的问题给我一个线索，我将不胜感激。

【问题讨论】：
-
应该是
<%- include，而不是<% include。 -
感谢@BenFortune，但我仍然认为输出没有区别，但很感激！
-
尝试将
<% include ../path/to/include %>更改为<%- include ('../path/to/include') %> -
@ponury-kostek，没有变化，但谢谢
