设置与迁移的关联后，吸气器不存在

Question

我正在尝试使用续集设置1：n关联。当我尝试访问生成的getter函数时，出现错误，提示它们不存在。

如果有两个具有1：n关联的对象，我将按照以下方式定义模型

'use strict';
module.exports = (sequelize, DataTypes) => {
  const Locations = sequelize.define('Locations', {
    owner: DataTypes.INTEGER,
    latitude: DataTypes.DOUBLE,
    longitude: DataTypes.DOUBLE
  }, {});

  Locations.associate = function(models) {
    // associations can be defined here
    Locations.hasMany(models.LocationOpeningHours, {
      as: 'locationOpeningHours',
      foreignKey: 'locationId',
      sourceKey: 'id',
    })
  };
  return Locations;
};

'use strict';
module.exports = (sequelize, DataTypes) => {
  const LocationOpeningHours = sequelize.define('LocationOpeningHours', {
    locationId: DataTypes.INTEGER,
    weekday: DataTypes.TINYINT,
    hours: DataTypes.STRING
  }, {});
  LocationOpeningHours.associate = function(models) {
    // associations can be defined here
    LocationOpeningHours.belongsTo(models.Locations,
        {
          as: 'locations',
          foreignKey: 'id',
          sourceKey: 'locationId',
        })
  };
  return LocationOpeningHours;
};

您期望发生什么？

 locations.findOne({where: {id: locationId}})
     .then(location => {
          location.getLocationOpeningHours()
              .then(openingHours => log(openingHours))

}

我希望看到该位置的locationOpeningHours

实际上发生了什么？

我得到了错误：

希望任何人都可以指出正确的方向
