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.
所以我有一个 2 模型(患者和预订),我想从预订中获得耐心
// 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'
}
}
};
按照错误提示从 attributes
键中删除 type
属性 Patients.js

// Patients
module.exports = {
tableName: 'patients',
primaryKey: 'id',
attributes: {
id: {
type: 'number',
