Javascript 无法从graphql数据库更新mongodb集合

我无法解决以下问题。我开始使用NodeJS、Apollo和Mongoose开发GraphQL服务器

以下是数据库中的一些示例数据：

处方设置

{
                "_id": "5ea99ae6fc48d036e083ec20",
                "name": "Calcium",

                "isNormal": false
            },
            {
                "_id": "5ea99ae6fc48d036e083ec21",
                "name": "Calcium",
                "valueTo": 100,

                "isNormal": false
            },
            {
                "_id": "5ea99ae6fc48d036e083ec89",
                "name": "Calcium",

                "isNormal": false
            },
            {
                "_id": "5ea99ae6fc48d036e083ec8a",
                "name": "Calcium",

                "isNormal": false
            },
            {
                "_id": "5ea99ae6fc48d036e083ec22",
                "name": "Magnesium",
                "valueTo": 100,
                "valueFrom": 76,
                "treatmentDescription": "High Bio-unavailable",
                "recommendation": "<p><strong>Magnesium Excess</strong></p>\n<p><strong>S &amp; S include:</strong></p>\n<p>Confusion, Fatigue, Depression, Low blood pressure, Diarrhea, Muscle weakness</p>\n<p><strong>Magnesium sources:</strong></p>\n<p>Spinach, figs, avocado, banana and raspberries.

                "isNormal": false
            },
            {
                "_id": "5ea99ae6fc48d036e083ec53",
                "name": "Magnesium",
                "valueTo": 25,
                "valueFrom": -25,
                "treatmentDescription": "Normal / Ideal zone",
                "recommendation": "",
                "isNormal": true
            },

我想做的是，从解析的DPDF上的每个数组中获取“名称”和“值”，检查“值””位于处方设置中的“值from”和“值to”之间的位置，并更新“详细信息”以及“说明”和“建议”

这就是我所做的。我创造了一个变异：

updateParsePdf: authenticated(async (parent, args, context, info) => {
      try {
        const pdf = await ParsePdf.findById(args._id);
        const newReport = await updatedReport(pdf._doc);
        const reportUpdated = await ParsePdf.findByIdAndUpdate(args._id, {
          newReport,
        }).exec();
          return reportUpdated._doc;
      } catch (error) {
        console.log("error: ", error);
        throw new AuthenticationError("Opps! Something went wrong.", error);
      }
    }),

更新报告方法

    const updatedReport = async (pdf) => {
    //pdf is the response from the ParsedPdf above
  let updated = {};
  try {
    await Object.keys(pdf).forEach((key) => {
      const field = pdf[key];
      if (Array.isArray(field)) {
        const newRep = field.map(async (f) => {
          const pp = PrescriptionSetup.find({
            name: f.name,
            valueFrom: {
              $lte: f.value,
            },
            valueTo: {
              $gte: f.value,
            },
          })
            .exec()
            .then((p) => {
              return {
                ...f,
                details: {
                  description: p[0].treatmentDescription,
                  recommendation: p[0].recommendation,
                  isNormal: p[0].isNormal,
                },
              };
            })
            .catch((e) => {
              console.log("Error finding setup: ", e);
            });
          return pp;
        });
        updated = { ...updated, [key]: [...newRep] };
      }
    });
    const aa = { ...pdf, ...updated };
    return aa;
  } catch (error) {
    console.log("Error...: ", error);
  }
};

ParsedPdf集合中有很多数组，其中包含很多项。我认为由于巨大的数据库查询，我无法使它工作。 解决这个问题的最佳方法是什么

感谢您的帮助

我将建议一种代码更改最少的方法

const pp=PrescriptionSetup。在这里查找
pp
是一个
Promise
，因此
newRep
将是
Promise
的数组

而不是
[…newRep]
使用
[…等待承诺。all（newRep）]

wait Object.keys（pdf）.forEach（（key）=>…）

此处

。forEach

不返回任何内容，实际上您不必

wait

，但我们在（1.）中添加了一个异步逻辑，所以我们必须处理它

更改为

wait Promise.map（Object.keys（pdf），async（key）=>…）

如果您使用

bluebird

，则使用与Promise.map等效的东西

---

你确定

ParsedPdf

中的

value

是一个

String

？而

valueFrom

，

valueTo

是

Number

s吗？有什么不起作用的是出现了错误或者它没有按照它应该的那样更新？我观察到的问题主要与异步操作有关。你忘了把

wait

在一些应该出现的地方，你把它们放在不应该出现的地方appear@TheeSritabtim你能告诉我等待的正确位置吗？

查找

查询正在运行。谢谢。这解决了问题。以前没有听说过

，尝试一下。谢谢你的建议
