我的模型（此模型中没有'test_field'）
getAppModel(){
var AppSchema = mongoose.Schema({

},

}, { strict: false,"versionKey": false });
try{
var AppModel = mongoose.model(this.appCollection);
}catch(error){
var AppModel = mongoose.model(this.appCollection, AppSchema, this.appCollection);

return AppModel;
}
我的路线
router.get('/dashboard', checklogin, function(req, res){
//res.sendFile("dashboard.html", {"root": __dirname.replace('routes','views')});
var appControllerObj = new appController();
appControllerObj.getAllApps()
.then(function(result){
var template_data = {apps: result};
console.log(template_data);
//在这里，我正在记录template_data，问题末尾在下面给出了其日志
var views_path = __dirname.replace('routes','views');
var inFile = views_path + '/dashboard.hbs';
var outFile = views_path + '/dashboard.html';
var source = fs.readFileSync(inFile, 'utf8');
var template = handlebars.compile(source, { strict: true });
var html = template(template_data);
fs.writeFileSync(outFile, html);
res.sendFile("dashboard.html", {"root": __dirname.replace('routes','views')});
}).catch(function(err){
console.log(err);
res.send(err);
});
});

问题：模型定义中没有的任何字段都不会 通过手柄栏进行编译，因此不会显示在视图中。
当我在猫鼬模型中添加字段时，它工作得很好。
记录template_data（无论我是否在模型中添加数据，test_field始终在结果对象中）
假设：当字段位于结果对象中时，应由车把进行编译。它与猫鼬模型有什么关系？

overview: 'URL shortening is a technique on the World Wide Web in which a Uniform Resource Locator (URL) may be made substantially shorter and still direct to the required page. This is achieved by using a redirect which links to the web page that has a long URL. For example, the URL "http://example.com/assets/category_B/subcategory_C/Foo/" can be shortened to "https://example.com/Foo". Often the redirect domain name is shorter than the original one. A friendly URL may be desired for messaging technologies that limit the number of characters in a message (for example SMS), for reducing the amount of typing required if the reader is copying a URL from a print source, for making it easier for a person to remember',
