Question

最近，当我在Sequelize中进行bulkCreate时遇到了一些麻烦。我收到以下错误：

TypeError: Cannot read property 'set' of undefined
at results.forEach (/Users/mzd/Desktop/Shroogal/shroogal-dev/node_modules/sequelize/lib/model.js:2357:27)

这是我的续集迁移文件：

module.exports = function(sequelize, DataTypes) {
return sequelize.define('documentsInstruments', {
docid: {
  type: DataTypes.INTEGER(11),
  allowNull: false,
  primaryKey: true,
  autoIncrement: true,
  field: 'docid'
},
iid: {
  type: DataTypes.BIGINT,
  allowNull: true,
  references: {
    model: 'EntityInstruments',
    key: 'IID'
  },
  field: 'IID'
},
docType: {
  type: DataTypes.STRING(45),
  allowNull: true,
  field: 'docType'
},
docPath: {
  type: DataTypes.STRING(200),
  allowNull: true,
  field: 'docPath'
},
creationDate: {
  type: DataTypes.DATE,
  allowNull: true,
  field: 'creationDate'
},
addlInfo: {
  type: DataTypes.STRING(500),
  allowNull: true,
  field: 'addlInfo'
},
posLabel: {
  type: DataTypes.STRING(45),
  allowNull: true,
  field: 'posLabel'
},
active: {
  type: DataTypes.STRING(3),
  allowNull: true,
  defaultValue: 'Y',
  field: 'active'
},
origFileName: {
  type: DataTypes.STRING(400),
  allowNull: true,
  field: 'origFileName'
}
}, {
  tableName: 'Documents_Instruments'
});
};

这是我的bulkCreate函数：

            if(obj.documents) {
            let data = [];
            obj.documents.forEach((v, i) => {
                var d = {};

                if(v.docid)
                  d.docid                  = v.docid;

                if(obj.iid)
                  d.iid                    = obj.iid;

                if(v.type)
                  d.docType                = v.type;

                if(v.filePath)
                  d.docPath                = v.filePath;

                if(v.date)
                  d.creationDate           = v.date;

                if(v.additionalDescription)
                  d.addlInfo               = v.additionalDescription;

                if(v.originalName)
                  d.origFileName           = v.originalName;

                data.push(d);
              });

              this.documentsInstruments
               .bulkCreate(data, {
                  updateOnDuplicate: ['docType', 'docPath', 'creationDate', 'addlInfo', 'origFileName']
               })
               .then((d) => {
                resolve(d);
               })
               .catch((err) => {
                reject(err);
               });

        }

我检查源代码（node_modules / sequelize / lib / model.js：2357：27）并尝试打印一些用于调试的东西，实例[i]在此变为unfine.QueryInterface.bulkInsert函数

我遇到了同样的问题，我也无法找出为什么会出现错误。

但是当我将sequelize库版本从v4.4.2升级到4.11.0时，那个错误就不再显示了。

如果您的版本不是最新版本，请尝试升级版本。

sequelize BulkCreate无法读取未定义的属性'set'
