我在搜索时遇到了问题，包括按某个点的距离排序。这是我的代码以及我要执行的操作。感谢帮助

const Sequelize = require('sequelize');

var Flat = db.define('flat', {
    id: {
        type: Sequelize.INTEGER,
        autoIncrement: true,
        primaryKey: true
    }
});

var FlatAddress = db.define('flat_address', {
    id: {
        type: Sequelize.INTEGER,
        autoIncrement: true,
        primaryKey: true
    },
    flat_id: {
        type: Sequelize.INTEGER,
        foreignKey:true,
        allowNull:false,
        references: {
            model:'flats',
            key: 'id'
        }
    },
    city: {
        type: Sequelize.STRING(50) //post_town
    },
    location: {
        type: Sequelize.GEOMETRY('POINT')
    }
});

Flat.hasOne(FlatAddress, { as: 'Address', foreignKey: 'flat_id', otherKey: 'id', onDelete: 'cascade' });

FlatAddress.belongsTo(Flat, { foreignKey: 'id', otherKey: 'flat_id', onDelete: 'cascade' });

我想做这样的事情 …
