Question

我认为此find函数的语法可能不正确，因为即使不存在文档，它仍会说有一个'docs'，但是如果文档存在，则应该作为记录的'docs'只会返回空？

功能：

  addRefund : (refundCalc, callback) => {
    order_number = refundCalc.refundDetails.customer_details.order.order_number;
    console.log('TYPE OF ORDER NUMBER' + typeof order_number)
    dbconnect.createConnection()
    refund.find({order_number: order_number}, (err, docs) => {
        if (docs) {
            console.log('docss!!!!!!!!!!!!!' + docs[0])
            console.log('calling within error!!!!!!')
            let notStored = {"refundDocStored" : "False"}
            callback(notStored)
            dbconnect.closeConnection();
        }

然后是我的架构，这是我可能出错的地方，也许是它无法正确查找我不知道的订单号-

Answer 1

尝试与toArray函数一起使用

addRefund : (refundCalc, callback) => {
    order_number = refundCalc.refundDetails.customer_details.order.order_number;
    console.log('TYPE OF ORDER NUMBER' + typeof order_number)
    dbconnect.createConnection()
    refund.find({order_number: order_number}).toArray(function(err, docs) {
        if (docs) {
            console.log('docss!!!!!!!!!!!!!' + docs[0])
            console.log('calling within error!!!!!!')
            let notStored = {"refundDocStored" : "False"}
            callback(notStored)
            dbconnect.closeConnection();
        }})}

尝试使用点表示法访问嵌入式数组

addRefund : (refundCalc, callback) => {
order_number = refundCalc.refundDetails.customer_details.order.order_number;
console.log('TYPE OF ORDER NUMBER' + typeof order_number)
dbconnect.createConnection()
refund.find({customer_details.order.order_number: order_number}, (err, docs) => {
    if (docs) {
        console.log('docss!!!!!!!!!!!!!' + docs[0])
        console.log('calling within error!!!!!!')
        let notStored = {"refundDocStored" : "False"}
        callback(notStored)
        dbconnect.closeConnection();
    }

MongoDB Find函数不返回，即使存在
