当我从add重定向到show列表时，最后一个插入的数据没有显示在nodejs中

Question

在我的代码中，当我从添加数据重定向时，在这种情况下，它不会获取最新的数据，但当我刷新时，它会获取该数据

var CountryResponseData = [];
router.get('/', ensureAuthenticated, (req, res) => {
Country.find({}).then(countrylist =>{
console.log(countrylist);
if(countrylist){
CountryResponseData = countrylist;
}else{
CountryResponseData = "empty";
}
});
res.render('countrymgmt/list', { layout: "layoutinternal", title: "List Of Countries","countries":CountryResponseData });
});

Answer 1

这将是一个问题，因为从数据库中提取数据直到它呈现视图页面需要花费时间

var CountryResponseData = [];router.get('/', ensureAuthenticated, (req, res) => {
Country.find({}).then(countrylist =>{
console.log(countrylist);
if(countrylist){
res.render('countrymgmt/list', { layout: "layoutinternal", title: "List Of Countries","countries":countrylist });
}else{
res.render('countrymgmt/list', { layout: "layoutinternal", title: "List Of Countries","countries":[] });
}
});

})；
