SequelizeDatabaseError：列\\“ functionCode \\”不存在

Question

我正在編寫一個簡單的NodeJS代碼以使用sequelize從postgres讀取/寫入。 我的代碼適用於一個表，但是當測試另一個不相關的表時，類似的代碼也會中斷。 從錯誤堆棧跟蹤可以看出，我還發現拋出的錯誤令人困惑。

我禁用了timestamp列，並在CLI上執行了SQL，sequelize遇到了問題。

首先，這是/tfnMetadata.js中的模型

'use strict';

/**
 * Model definition: See http://docs.sequelizejs.com/manual/models-definition.html
 *  See DataTypes: http://docs.sequelizejs.com/manual/data-types.html
 * @param
 * @returns {*} records.
 */
module.exports = (sequelize, DataTypes) => {
  const tfnMetadata = sequelize.define('tfn_metadata', {
    did: {
      type: DataTypes.STRING, primaryKey: true, allowNull: false,
    },
    dnis: {
      type: DataTypes.STRING,
    },
    functionCode: {
      type: DataTypes.STRING,
    },
    country: {
      type: DataTypes.STRING,
    },
    language: {
      type: DataTypes.STRING,
    },
    coBrand: {
      type: DataTypes.BOOLEAN,
    },
    collections: {
      type: DataTypes.BOOLEAN,
    },
    smallBusiness: {
      type: DataTypes.BOOLEAN,
    },
    welcomeMessageCode: {
      type: DataTypes.STRING,
    },
    welcomeMessage: {
      type: DataTypes.TEXT,
    },
    referenceKey: {
      type: DataTypes.STRING,
    },
    partner: {
      type: DataTypes.STRING,
    },
  }, { timestamps: false, tableName: 'tfn_metadata' });
  tfnMetadata.sync({ alter: true });
  return tfnMetadata;
};

psql中表的對應架構為：

Column       |          Type          | Nullable | 
--------------------+------------------------+----------+
 did                | character varying(15)  | not null |
 dnis               | character varying(15)  |          |
 functioncode       | character varying(20)  |          |
 country            | character varying(25)  |          |
 language           | character varying(20)  |          |
 cobrand            | boolean                |          |
 collections        | boolean                |          |
 smallbusiness      | boolean                |          |
 welcomemessagecode | text                   |          |
 welcomemessage     | character varying(200) |          |
 referencekey       | character varying(50)  |          |
 partner            | character varying(50)

然后是標准的./models/index代碼（ ./models/index ），它讀取模型定義文件以導入模型。 編輯-這是我沒有提供的唯一代碼，但與此處給出的代碼幾乎相同： https : //sequelize.readthedocs.io/en/1.7.0/articles/express/

使用以下函數在query.js文件中執行查詢：

const models = require('./models/index');

const getByPk = async (didNumber) => {
  try {
    const record = await models.tfnMetadata.findByPk(didNumber.toString());
    logger.info('Query.getByPk() Returned the record from db.', record);
    return record.dataValues;
  } catch (err) {
    logger.error('Query.getByPk() failed:', err);
    throw err;
  }
};

上面的代碼在client.js中被調用為-

const query = require('../../src/clients/pg/query');
const tfnData = await query.getByPk(did);

但是它失敗了-

Query.getByPk() Request to get record for did=111 undefined
Query.getByPk() failed: {

  }
error: End - Error:

    "errorMessage": "column \"functionCode\" does not exist",

    "stackTrace": [

        "Promise._settlePromiseFromHandler (/Users/.../node_modules/bluebird/js/release/promise.js:512:31)",

錯誤代碼指示未定義列或缺少列functionCode ，提示正在詢問我是否要引用functionCode 。

表字段的名稱使用小寫或下划線，而不是駝峰式
