Question

我有这个功能，

module.exports.getDepartments = function () {
    return new Promise(function (resolve, reject) {
        sequelize.sync().then(function () {
            Departments.findAll({
                attributes: ['departmentId', 'departmentName']
            }).then(function(data){
                    resolve(data);
            }).catch(function(err) {
                reject("Error: " + err);
            })
        });
    }
)};

当我console.log()数据时，我得到所有这些奇怪字段的所有记录！

Departments {
  dataValues: { departmentId: 5, departmentName: '' },
  _previousDataValues: { departmentId: 5, departmentName: '' },
  _changed: {},
  _modelOptions:
   { timestamps: true,
     validate: {},
     freezeTableName: false,
  _options:
   { isNewRecord: false,
     _schema: null,
     _schemaDelimiter: '',
     raw: true,
     attributes: [ 'departmentId', 'departmentName' ] },
  __eagerlyLoadedAssociations: [],
  isNewRecord: false }

  Departments {
  dataValues: { departmentId: 6, departmentName: 'TEST' },
  _previousDataValues: { departmentId: 6, departmentName: 'TEST' },
  _changed: {},
  _modelOptions:
   { timestamps: true,
     validate: {},
     freezeTableName: false,
  _options:
   { isNewRecord: false,
     _schema: null,
     _schemaDelimiter: '',
     raw: true,
     attributes: [ 'departmentId', 'departmentName' ] },
  __eagerlyLoadedAssociations: [],
  isNewRecord: false }

我不得不用20个字段来缩短它，但你明白了。这是怎么回事？这使我无法在我的res.render上运行server.js，因为它在departmentId和departmentName上有所期待，但正在变得越来越多。

您需要指示Sequelize返回原始数据。默认情况下，它会在行结果上创建实例。

示例：

BoundingBox

Sequelize返回的字段多于请求的数量
