Question

我正在使用DAO将文档插入数据库。使用Bull包从Controller和工作处理器调用此函数。

刀/ user.dao.js：

exports.create = function (data) {
    // Create and Save a new User
    const user = new User(data);

    return new Promise(function (resolve, reject) {
      user.save(function (error, data) {
        if (error) {
          reject(new Error(error));
        } else {
          pino.debug('Data saved to database: ' + JSON.stringify(data));
          resolve(data);
        }
      });
   });
};

user.controller.js :(这适用于......）

exports.create = function (req, res) {
  const uuid = uuidv4();
  const userDAO = require('../daos/user.dao');

  userDAO.create({
    fullName: req.body.fullName,
    email: req.body.email,
    uuid: uuid
  }).then(function (data) {
    // ... Add to mail queue & send registration link.
    res.send(data);
  }).catch(function (error) {
    res.status(500).send(// ... Send Errors);
 });
};

users-upload.processor.js :(这不起作用）

module.exports = function (job, done) {
  job.progress(0);

  const workbook = new Excel.Workbook();
  workbook.xlsx.readFile(path.join(__dirname, '../../uploads/' + job.data.filename))
    .then(() => {
      pino.debug("XLSX file is Read.");
      workbook.eachSheet(function (worksheet, sheetId) {
        worksheet.eachRow(function (row, rowNumber) {
          if (rowNumber !== 1) {
            pino.debug(`Row ${rowNumber} = ${JSON.stringify(row.values)}`);

            const uuid = uuidv4();
            const userDAO = require('../daos/user.dao');

            userDAO.create({
              fullName: row.values[1],
              email: row.values[2].text,
              uuid: uuid
            }).then(function (data) {
              // ... Add to a mail queue.
            }).catch(function (error) {
              pino.error(error);
            });
          }
        });
      });
    });

    pino.debug('Finished processing users upload...');
    job.progress(99);
    done();
  };

在这两种情况下，预先保存的钩子都会被解雇。

user.model.js：

// ... Schema Definition.

userSchema.pre('save', function (next) {
  const unverifiedUser = this;
  pino.debug(`Pre-Save Unverified User... ${JSON.stringify(this)}`);
  next();
});

以下是该事件的日志：

我一直在搜索谷歌和stackoverflow并尝试各种组合，没有任何作用。如果我将处理器中的代码放入控制器，它可以完美地工作。我不知道该怎么办。

根据此issue，Bull进程当前不支持Mongoose查询。因此，您将必须使用MongoDB本机驱动程序。

Mongoose .save（）无法在作业队列中工作
