节点 js：关联在 Sails js 版本 1 中不起作用

Question

请帮助我，我正在使用 Sails 版本 1，我想创建关联，但出现错误。

error: A hook (`orm`) failed to load!
error: Could not tear down the ORM hook.  Error details: Error: Invalid data store identity. No data store exist with that identity.
error: Failed to lift app: { userError: The attribute `id` on the `patients` model is an association but also specifies a type property. This is not needed and will be automatically determined.

所以我有 2 个模型（患者和预订），我想从预订中获得患者

//Patients.js

module.exports = {
tableName: 'patients',
primaryKey: 'id',
attributes: {
    id: {
        model: 'Bookings',
        type: 'number',
        unique: true
    }
},

};

// Bookings.js

module.exports = {
tableName: 'booking',
attributes: {
    patient: {
        collection: 'Patients',
        via: 'id'
    }
}

};

Answer 1

按照错误提示，从Patients.js 中的attributes 键中删除type 属性。

// Patients
module.exports = {
tableName: 'patients',
primaryKey: 'id',
attributes: {
 id: {
    type: 'number',
    unique: true
    },
 RandomAssociationName: {
    model: 'Bookings'
    }
}

// Bookings
module.exports = {
tableName: 'booking',
attributes: {
patient: {
    collection: 'Patients',
    via: 'RandomAssociationName'
  }
}
