Я пытаюсь визуализировать навигационную панель динамически, я использую ejs и паспорт, у меня была проблема с тем, что он продолжал говорить, что пользователь не определен, но я все еще не знаю, что делать после попытки req.isAuthenticated, а также req.user для пользователя в рендеринге. Я рендеринг их в контроллере администратора, но я опубликую администратор и контроллер аутентификации, а также app.js
navigation.ejs
<% if (!user) { %>
<ul>
<li><a href="/">home</a></li>
<li><a href="/signup">signup</a></li>
<li><a href="/login">login</a></li>
</ul>
<% } else { %>
<ul>
<li><a href="/">posts</a> </li>
<li><a href="/myposts">myposts</a> </li>
<li><a href="/createpost">createpost</a></li>
<li>
<form action="/logout" method="post">
<input type="hidden" name="_csrf" value="<%= csrfToken %>">
<button type="submit">Logout</button>
</form>
</li>
</ul>
<% } %>
