我的 servfer 操作 next.js 出现 TypeScript 类型错误

Question

需要有关我的 Next.js 应用程序上的服务器操作的帮助，给我一个类型错误并且无法查明原因，当 orderProduct 的

db.insert

上有 3 个值时，它就会出现，并且总是错误地输出第一个值无论它是什么领域。

创建订单.tsx

products.map(async ({ productId, quantity, variantId }) => {
  await db.insert(orderProduct).values({
    productVariantId: variantId,
    productId: productId,
    quantity,
    orderId: order[0].id,
  })
})

架构

export const orderProduct = pgTable('order_product', {
  id: serial('id').primaryKey(),
  quantity: integer('quantity').notNull(),
  productVariantId: serial('productVariantId')
    .notNull()
    .references(() => productVariants.id, { onDelete: 'cascade' }),
  productId: serial('productId')
    .notNull()
    .references(() => products.id, { onDelete: 'cascade' }),
  orderId: serial('orderId')
    .notNull()
    .references(() => orders.id, { onDelete: 'cascade' }),
})

类型

import * as z from 'zod'

export const createOrderSchema = z.object({
  total: z.number(),
  status: z.string(),
  paymentIntentId: z.string(),
  products: z.array(
    z.object({
      quantity: z.number(),
      productId: z.string(),
      variantId: z.string(),
    }),
  ),
})

错误信息

No overload matches this call.
  Overload 2 of 2, '(values: { quantity: number | SQL<unknown> | Placeholder<string, any>; id?: number | SQL<unknown> | Placeholder<string, any> | undefined; productId?: number | SQL<...> | Placeholder<...> | undefined; productVariantId?: number | ... 2 more ... | undefined; orderId?: number | ... 2 more ... | undefined; }[]): PgInsertBase<...>', gave the following error.
    Object literal may only specify known properties, and 'productVariantId' does not exist in type '{ quantity: number | SQL<unknown> | Placeholder<string, any>; id?: number | SQL<unknown> | Placeholder<string, any> | undefined; productId?: number | SQL<...> | Placeholder<...> | undefined; productVariantId?: number | ... 2 more ... | undefined; orderId?: number | ... 2 more ... | undefined; }[]'.ts(2769)

这是错误，如果我移动 db.insert 的值，它会是相同的

找到答案，在我的类型上，对于

z.number()

和

z.string()

 应该是 

productId

 而不是 

variantId

import * as z from 'zod'

export const createOrderSchema = z.object({
  total: z.number(),
  status: z.string(),
  paymentIntentId: z.string(),
  products: z.array(
    z.object({
      quantity: z.number(),
      productId: z.number(),
      variantId: z.number(),
    }),
  ),
})
