Express 引导模式不'；无法显示正确的post\u id

当我在一个对象数组上循环时，我试图访问代码开头给出的post_id。我在每一点上甚至在模型内部发布post.post_id。问题：显示的post\u id与给定的post是正确的，直到post.post\u id位于模式内。。。然后，它会显示最近一篇文章的post.post_id，而不是正确的post.post_id。。。下面是我的代码：引导模式会改变post.post_id的值，有什么原因吗？我似乎找不到我正在犯的错误

[这是我遇到的问题的一个例子，post ID在达到模式之前都很好]

        <%- include ('./partials/header.ejs') %>

        <h3 class="greeting">Hi <%=username%>, check out what others are posting:) </h3>



        <% for (let post of allPosts) { %>



        <div class="postBox">
            first <%=post.post_id%>

            <div class="postHead">
                <a id="username" href="/<%=post.username%>"><%=post.username%></a>
                second  <%=post.post_id%>
            </div>

            <div class="postBody">
