我有一个名为 Product 的模型，它有两个字段 id 和 name。我安装了脚印。
'use strict'
const Model = require('trails/model')
/**
* @module Product
* @description TODO document Model
*/
module.exports = class Productextends Model {
static config (app, Sequelize) {
return {
store: 'db',
options: {
schema: 'dbo',
tableName: 'dimProduct',
timestamps: false,
classMethods: {
//If you need associations, put them here
associate: (models) => {
}
}
}
}
}
static schema (app, Sequelize) {
return {
id: {
type: Sequelize.STRING,
allowNull: false,
primaryKey: true,
field: 'ProductCode'
},
name: {
type: Sequelize.STRING,
field: 'ProductName'
}
}
}
}
当我使用邮递员和 GET 请求localhost:3000/product?id=XX2525时，记录器中生成的 sql 是
SELECT [Product].[ProductCode] AS [id], [Product].[ProductName] AS [name] FROM [dbo].[dimProduct] AS [Product] WHERE [Product].[ProductCode] = N'XX2525';
如果我对以数字开头的 id 执行相同的查询，localhost:3000/product?id=10XX2525则生成的 sql 为
SELECT [Product].[ProductCode] AS [id], [Product].[ProductName] AS [name] FROM [dbo].[dimProduct] AS [Product] WHERE [Product].[ProductCode] = 10;
我不确定这是追踪还是续集，但如果我在模型中将字段定义为字符串，我希望查询搜索为字符串而不应用任何转换。错误看起来像（001CAR 是我数据库中的第一个 id）：
