Question

我有一个使用续集的模型“ User”和一个“ Set”模型。尝试创建Set时，我不断收到此错误：

“错误：列“ user_id”中的空值违反了非空约束”

我非常清楚地传递了user_id。这是路线。控制台日志显示user_id（按预期）和类型（按预期）。但是我得到了错误。

这是我的用户模型。我使用的是较旧的语法，但它似乎仍然可以工作……除此之外。

router.post('/create', jsonParser, async (req, res) => {
    console.log("ROUTE", req.body.user_id, typeof req.body.user_id)
    try {
        const set = await Set.create({
            name: req.body.name, 
            user_id: req.body.user_id
        }); 
        return res.status(202).json({ set }); 
    }
    catch(err) {
        console.error(err)
        return res.sendStatus(404)
    }
});

这是Set模型：

const User = sequelize.define('User', 
    {
        id: {
            type: Sequelize.INTEGER, 
            primaryKey: true, 
            autoIncrement: true
        }, 
        username: {
            type: Sequelize.STRING, 
            allowNull: false, 
            unique: true
        }, 
        password: {
            type: Sequelize.STRING, 
            allowNull: false
        }
    }, 
    {
        tableName: 'users', 
        timestamps: false, 
        underscored: true
    }
);

User.associate = function(models) {
    User.hasMany(
        models.Set, 
        {
            as: 'set', 
            foreignKey: { allowNull: false }, 
            onDelete: 'CASCADE'
        }
    )
}

有人可以看到我在这里搞砸吗？
