您如何在 Sequelize 中连接 3 个未全部链接的表

Question

我有 4 个表 Properties、Units、Leases、LeaseRates。

Units	Leases	LeaseRates
propertyId	unitId	leaseId

都是和最后一个id关联的

我有这样的关系设置

Properties.hasMany(Units);
Units.belongsTo(Properties);

Units.hasMany(Leases);
Leases.belongsTo(Units);

Leases.hasMany(LeaseRates);
LeaseRates.belongsTo(Leases);

在 Sequelize 中有没有简单的方法让我通过 propertyId 查询 LeaseRates？

Answer 1

<pre>
await properties.findOne({
       where: { id },
       include: [{
         model: model.Unit, as: 'unit',
         attributes: ['id'],
         include: [{
           model: model.Leases, as: 'leases',
           attribute: ['id'],
           include: [{ model: model.LeaseRates, as: 'leaserates' }]
         }]
       }]
     })
</pre>
