Question

Sequelize与给定的sequelizerc / config.js文件连接
Sequelize运行迁移文件并使用定义的模型创建表
Sequelize运行种子文件，但是尝试查询创建的数据时出错，即错误：关系“来宾”不存在

我注意到的有趣事情：在查询User表时，我注意到它没有返回我期望的数据...而不是User表中的用户似乎正在返回我在上面设置的实际postgres数据库用户。

SEEDER FILE

var userId1 = uuidv4();
await queryInterface.bulkInsert(
  { tableName: 'User', schema: 'public' }, 
  [
    {email: "user1@email.com", id:userId1,  password: User.prototype.generateHash("password"), createdAt:dateUtil.createDateAsUTC(new Date()), updatedAt:dateUtil.createDateAsUTC(new Date())}
  ], {}
);

const user = await queryInterface.sequelize.query(
  `SELECT * from USER;`
);

console.log(user);

var guestId1 = uuidv4();
await queryInterface.bulkInsert(
  { tableName: 'Guest', schema: 'public' }, 
  [
    {id:guestId1, userId: userId1, createdAt:dateUtil.createDateAsUTC(new Date()), updatedAt:dateUtil.createDateAsUTC(new Date())}
  ], {}
);

const guest = await queryInterface.sequelize.query(
  `SELECT * from Guest;`
);

从挖掘看来，可能它未使用正确的数据库模式？我在public下的postgres中有一个，所有表均已正确创建，并且种子数据已正确添加到db中。我试图将架构添加到config.js和模型文件中，但是没有任何效果。

CONFIG.JS

development: {
        username: process.env.DATABASE_USERNAME,
        password: process.env.DATABASE_PASSWORD,
        database: process.env.DATABASE_NAME,
        host: process.env.DATABASE_HOST,
        url: process.env.DATABASE_URL,
        dialect: 'postgres',
        define: {
            schema: "public"
        }
    }

Guest.js

module.exports = (sequelize, DataTypes) => {
  var Guest = sequelize.define('Guest', {}, 
  {
    tableName:"Guest",
  });
  Guest.associate = function(models) {
    Guest.belongsTo(models.User, {as: 'User', foreignKey: 'userId'}); // Adds userId 
  };
  return Guest;
};

注销queryInterface模型时似乎是空的。...

QueryInterface {
  sequelize:
   Sequelize {
     options:
      { dialect: 'postgres',
        dialectModulePath: null,
        host: 'localhost',
        protocol: 'postgres',
        define: {},
        query: {},
        sync: {},
        timezone: '+00:00',
        logging: [Function: logMigrator],
        omitNull: false,
        native: false,
        replication: false,
        ssl: false,
        pool: {},
        quoteIdentifiers: true,
        hooks: {},
        retry: [Object],
        transactionType: 'DEFERRED',
        isolationLevel: null,
        databaseVersion: '9.4.0',
        typeValidation: false,
        benchmark: false,
        operatorsAliases: true,
        username: 'username',
        password: 'password',
        database: 'dbname',
        url: 'postgres://username:password@localhost:5432/dbname',
        port: '5432' },
     config:
      { database: '<dbname>',
        username: '<username>',
        password: 'password',
        host: 'localhost',
        port: '5432',
        pool: {},
        protocol: 'postgres',
        native: false,
        ssl: false,
        replication: false,
        dialectModulePath: null,
        keepDefaultTimezone: undefined,
        dialectOptions: undefined },
     dialect:
      PostgresDialect {
        sequelize: [Circular],
        connectionManager: [Object],
        QueryGenerator: [Object] },
     queryInterface: [Circular],
     models: {},
     modelManager: ModelManager { models: [], sequelize: [Circular] }

使用表名周围的双引号纠正了该问题：

const guest =等待queryInterface.sequelize.query（ SELECT * from "Guest"; ）;

序列化：播种时查询表时不存在关系“ <tablename>”
