我现在使用 express js 作为框架，将 ejs 用于特定控制器的视图引擎，同时从控制器传递数据以查看它显示用户未在 view/partial/header.ejs 中定义，这对于其他控制器来说工作正常。
控制器代码：
app.get('/add_home_content', function(req, res) {
User.findById(req.user, function(err, doc) {
if (doc.local.role == 'admin') {
var catId = '59f9be1aa40c152bc990f98f';
var contentid2 = '59faef18ce5da81b59c70a34';
var homeimgid = "59fc0e3e20942a15d7633cfd";
var contentplanid = "5a002bf79a62fc0bf2f14bbe";
content.findById(catId, function(err, content) {
//content.find({} ,{ "type": "homepage" }, function (err, content) {
//res.send(req.user.local);
trainercontent.findById(contentid2, function(err, trainercontent) {
homeimage.findById(homeimgid, function(err, homeimage) {
trainerinfo.find({}).exec(function(err, trainerinf) {
traininginfo.find({}).exec(function(err, traininginf) {
subscplancontent.findById(contentplanid, function(err, plancontent) {
banner.find({}).exec(function(err, bannerinf) {
// notification.find({}).exec(function(err, notifications) {
//res.send(content);
//trainercontent.find({}).exec(function(err, trainercontent) {
// res.send(notifications);
res.render('admin/content/addcontent.ejs', {
editContent: content,
editcontent2: trainercontent,
editcontent3: homeimage,
trainerinfo: trainerinf,
traininginfo: traininginf,
plancontents: plancontent,
bannerinfo: bannerinf,
message: false,
user: req.user.local
});
});
});
});
});
});
});
});
}
});
});
查看页面代码（查看引擎 ejs 代码）显示用户未定义错误：
