node.js - Sequelize : extra column in query

Question

我有下表定义
产品表

const Product = sequelize.define('product', {
  name: { type: Sequelize.TEXT },
  amount: { type: Sequelize.DECIMAL },
  category: { type: Sequelize.BIGINT, field: 'categoryId' },
  brand: { type: Sequelize.BIGINT, field: 'brandId' },
  vendor: { type: Sequelize.BIGINT, field: 'vendorId' },
  status: { type: Sequelize.BIGINT, field: 'statusId' },
  image: { type: Sequelize.TEXT },
  stock: { type: Sequelize.INTEGER },
  description: { type: Sequelize.TEXT },
  model: { type: Sequelize.TEXT },
  code: { type: Sequelize.TEXT },
});

状态表

const Statuses = sequelize.define('statuses', {
  name: {
    type: Sequelize.TEXT
  },
});

协会

Product.belongsTo(Statuses, { foreignKey: 'statusId', as: 'productStatus'});

当我运行以下内容时:

product = await Product.findOne({
  where: {
    id: req.query.id
  }, 
  include: ['productStatus']
})

我得到以下查询:

SELECT 
"product"."id", 
"product"."name", 
"product"."amount", 
"product"."categoryId" AS "category", 
"product"."brandId" AS "brand", 
"product"."vendorId" AS "vendor", 
"product"."statusId" AS "status", 
"product"."image", 
"product"."stock", 
"product"."description", 
"product"."model", 
"product"."code",
"product"."createdAt", 
"product"."updatedAt", 
"product"."statusId", 
"product"."categoryId", 
"product"."vendorId", 
"product"."brandId", 
"productStatus"."id" AS "productStatus.id", 
"productStatus"."name" AS "productStatus.name", 
"productStatus"."createdAt" AS "productStatus.createdAt", 
"productStatus"."updatedAt" AS "productStatus.updatedAt", 
"productStatus"."status" AS "productStatus.status" 
FROM "products" AS "product" 
LEFT OUTER JOIN "statuses" AS "productStatus" ON "product"."statusId" = "productStatus"."id" 
WHERE "product"."id" = '1'

不知道为什么

"productStatus"."status" AS "productStatus.status" 

是否存在并导致未知列错误，因为我在状态表中没有该列

Answer 1

User.hasOne(Status, { foreignKey: 'status', as: 'UserStatus'}) 表示 Status 具有不正确的 status 列。这就是为什么 Sequelize 知道 Status 模型有 status 列并将其添加到 SQL-query 中。
我想 User 有 status 列而不是 Status 。如果是这样，您只需要像这样更改关联:

User.belongsTo(Status, { foreignKey: 'status', as: 'UserStatus'})
