mongoose数据库怎么同步读取数据?
var newOrderList = {shopPlace : String}
async.map(orderList,function(oneOrder,cb){
Shop.findOne({'name': oneOrder.shopName},function(err,shop){
newOrderList.shopPlace = shop.place;
cb(null,newOrderList)
})
},function(err,results){
res.render('userOrderRecord',{
,'orderList': results
});
})
上述代码回调函数中newOrderList得到的是同一个值,但我希望Shop读取数据库的过程是同步的,newOrderList传给results四个不同的值,有什么方法?
