如何使用 Bookshelfjs 保存一对多关系

Question

所以我尝试了这个

let Book = bookshelf.Model.extend({tableName: 'book'})
let User = bookshelf.Model.extend({
    tableName: 'user',
    books: function() {
        return this.belongsToMany(Book) // i have table book_user with user_id and book_id fk to respective tables
    }
})
return User

然后我尝试使用此代码段进行保存

models.User.forge(myUserObject).save()    
.then(function (user) {
    return user.books().attach(myBookArray)
})

但它没有像预期的关系对象那样工作 (table book_user)

我该如何解决这个问题？

Answer 1

我用这段代码修复了它

return Promise.all([
    user: saveUser(),
    book: saveBook()
])
.then(function (result) {
    return result.user.books().attach([result.book.id])
})
