序列化create with associations

Question

我一直在尝试定义3个表之间的关系，然后在一个create函数中创建它们。由于某些原因，在创建3个模型时，链接ID(外键)是未定义的，并且不会传递。以下是它们之间的关联：

Person.js：

models.person.Lead = models.person.hasMany(models.lead, {
      onDelete: "CASCADE",
      foreignKey: "person_id"
});

Lead.js：

models.lead.Person = models.lead.belongsTo(models.person, {foreignKey: 'person_id'});

models.lead.Sealant_customer = models.lead.hasOne(models.sealant_customer, {
      onDelete: "CASCADE",
      foreignKey: 'lead_id'
})

sealantCustomer.js：

models.sealant_customer.Lead = models.sealant_customer.belongsTo(models.lead);

构建函数：

let sealantCustomer = models.sealant_customer.build({
                address: body.address,
                city: body.city,
                roof_size: body.roofSize,
                last_sealed: body.lastSealed,
                existingSealant: body.existingSealant,
                leaks_freq: body.leaksFrequency,
                floor: body.floor,
                elevator: body.elevator,
                panels: body.panels,
                home_type: body.homeType,
                urgency: body.urgency,
                next_step: body.nextStep,
                more_info: body.moreInfo,
                lead: {
                  site,
                  url: body.url,
                  date,
                  ip: body.ip,
                  person: {
                    name: body.name,
                    email: body.email,
                    phone: body.phone,
                    date,
                    city: body.city ? body.city : undefined,
                    address: body.address ? body.address : undefined,
                  }
                }
              }, {
                include: [{
                  model: models.lead,
                  association: models.sealant_customer.Lead,
                  include: [{
                    model: models.person,
                    association: models.lead.Person
                  }]
                }]
              })

输出的对象是好的，除了lead_id和person_id是空的这一事实(每个模型都有自己的ID，但没有相关模型的id)。我还应该注意到，没有验证错误，数据也很好。

Answer 1

据我所知，这个库在build函数中有一个bug。与create相同的语法可以完美地工作。

Answer 2

在Sequelize v6中，include部分中的关联标识符无效。否则，这个构建函数应该可以正常工作。
