更改关联后在 Eager loading 上 Sequelize Bad Field Error

Question

// Include Sequelize module. 
const Sequelize = require('sequelize') 
  
// Import sequelize object,  
// Database connection pool managed by Sequelize. 
const sequelize = require('./database.js') 

const User = require('./User.js');
const Product = require('./Product.js');
  
// Define method takes two arrguments 
// 1st - name of table 
// 2nd - columns inside the table 
const FavoriteProduct = sequelize.define('favorite_product', { 

    favorite_id:{ 
  
        // Sequelize module has INTEGER Data_Type. 
        type:Sequelize.INTEGER, 
  
        autoIncrement:true, 

        allowNull:false, 
  
        primaryKey:true
    }, 

    createdAt: Sequelize.DATE,

    //no dates

}, {
    updatedAt: false
}); 

User.hasMany(FavoriteProduct, { foreignKey: 'user_id'} );
Product.hasMany(FavoriteProduct, { foreignKey: 'product_id'} );

FavoriteProduct.belongsTo(Product, { foreignKey: 'product_id'});
FavoriteProduct.belongsTo(User, { foriegnKey: 'user_id'})

module.exports = FavoriteProduct

以前我将此模型作为 BelongsToMany 模型，通过 FavoriteProduct 具有 Product 和 User->belongToMany。我更改它是因为 FavoriteProduct 的急切加载在尝试从产品加载时不起作用。我现在有一个新问题，尝试急切加载新的 table 会抛出此错误：

    "code": "ER_BAD_FIELD_ERROR",
    "errno": 1054,
    "sqlState": "42S22",
    "sqlMessage": "Unknown column 'favorite_product.userUserId' in 'field list'",

我不知道为什么会这样，但一定是因为我试图从 belongsToMany 关联切换而不进行任何迁移。数据库中没有额外的列或类似的东西。

有谁知道如何在不删除 table 的情况下解决此字段问题？

作为参考，我只是这样做的：

await Product.findOne({
        include: [{
            model: FavoriteProduct,
            required: false,
        }]

Answer 1

您需要更正关联 FavoriteProduct.belongsTo(User：您拼错了选项 foreignKey，指出 foriegnKey。

FavoriteProduct.belongsTo(User, { foreignKey: 'user_id'})
