Question

我正在尝试使用sequelize-cli创建数据库并建立hasMany关联，但是由于某些原因，我无法在第二张表中填充数据

我在考虑该关联是否真的创建，在我的sgbd上我看不到“键”，即外键表示形式；我正在显示以下视频：https://www.youtube.com/watch?v=9xJLcTxlEIs 但只有我最喜欢的工作，只要显示此错误即可：

Listening on port 5000
Executing (default): INSERT INTO `categoria` (`id`,`nomept`,`nomeen`,`nomefr`,`createdAt`,`updatedAt`) VALUES (DEFAULT,?,?,?,?,?);

    at tryOnImmediate (timers.js:676:5)
    at processImmediate (timers.js:658:5)

我的服务器代码：

const Categoria = require('./models').categoria
const Faqs = require('./models').faqs

Categoria.create({
    nomept: 'terrs',
    nomeen: 'sqsdqs',
    nomefr: 'fdds'
}).then( cate => {
    cate.createfaqs({
        title: "teste terra",
        descricao: "dqsdsddqs dsd qd qd qdqq"
    }).then( () => console.log('funcionou'))
})

其他代码：

faqs.js：https://pastebin.com/4ww06n8k
categoria.js：https://pastebin.com/c8gD2GMG
migration / ... faqs.js：https://pastebin.com/kWYMxQxf
migration / ... categoria.js：https://pastebin.com/5J8ZYnAS

我希望cate.createFaqs（）能够正常工作，并将一些数据放入categoriaId属于表categoria的表中

我解决了这个问题，只需要添加以下代码：

参考：{ 型号：“类别”，密钥：“ id” }

在迁移代码中，瞧！

为什么这段代码无法创建序列关联
