Kes*_*vid 6 javascript sql postgresql upsert sequelize.js
所以我正在尝试使用model.upsert()ofsequelize并且我收到的所有内容都是 inserts ,无论我在查询中更改了什么。
我有一个事务模型,它有一些字段,带有默认生成的 id。
阅读续集的upsert文档我注意到这一点:
如果找到与主键或唯一键上提供的值匹配的行,则将执行更新。请注意,唯一索引必须在您的续集模型中定义,而不仅仅是在表中定义。
所以我猜我必须id在模型定义中定义事务的,所以我没有运气,因为它仍然只创建新条目..
TransactionModel = {
id: {
type: Sequelize.INTEGER,
allowNull: false,
primaryKey: true,
autoIncrement: true
},
{.......}
}

我做错了什么,我错过了什么?
任何解释和解决方案将不胜感激,提前致谢!
这是更新插入代码:
createOrUpdateTransaction: {
type: Transaction,
args: {
payerAccountNumber: {type: new GraphQLNonNull(GraphQLInt)},
recipientAccountNumber: {type: new GraphQLNonNull(GraphQLInt)},
amount: {type: new GraphQLNonNull(GraphQLFloat)},
currency: {type: new GraphQLNonNull(GraphQLString)},
paymentMethod: {type: new GraphQLNonNull(GraphQLString)},
cardNumber: {type: GraphQLFloat},
cardName: {type: GraphQLString},
cardNetwork: {type: GraphQLString},
cashMachineId: {type: GraphQLFloat},
receiptNumber: {type: new GraphQLNonNull(GraphQLFloat)},
invoiceNumber: {type: new GraphQLNonNull(GraphQLFloat)},
receiptCopy: {type: new GraphQLNonNull(GraphQLString)},

bankReference: {type: new GraphQLNonNull(GraphQLString)},

由于这是 a Mutationin 的一部分GraphQL。
可能值得注意的是,这是addTransaction之前,我改变的是db.models.transaction.upsert()从db.models.transaction.create()
在您的 upsert() 示例中,您没有提供upsert 方法的条目的id。这意味着 sequelize 无法将id与行匹配(因为id未定义),因此它会插入一个新行。
即使您使用不同的主键,它也必须始终是一个属性才能匹配,因为 sequelize 使用主键来搜索现有行。
createOrUpdateTransaction: {
type: Transaction,
args: {
// Omitted code...
},
resolve: (root, args) => {
return db.models.transaction.upsert({
// The id property must be defined in the args object for
// it to match to an existing row. If args.id is undefined
// it will insert a new row.
id: args.id,
time: new Date().toString(),
payerAccountNumber: args.payerAccountNumber,
recipientAccountNumber: args.recipientAccountNumber,
amount: args.amount,
currency: args.currency,
paymentMethod: args.paymentMethod,
cardNumber: args.cardNumber,
cardName: args.cardName,
cardNetwork: args.cardNetwork,
// Omitted fields ...
})
}
