Sequelize 创建关联

我一直在尝试定义 3 个表之间的关系，然后在一个创建函数中创建它们。出于某种原因，在创建 3 个模型时，链接 ID（外键）未定义且不会传递。以下是协会：

人物.js：

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

铅.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'
})

密封剂Customer.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
                  }]
                }]
              })

输出的对象很好，除了lead_id 和person_id 是空值（每个模型都有自己的ID，但没有关联模型的ID）。我还应该注意没有验证错误并且数据很好。
