Sequelize在创建时抛出"id必须是唯一的"

Question

Sequelize图书馆的新手.根据我的理解,'id'是由sequelize自动创建的(这就是我在数据库中看到的).但是当我去'创建'一个对象时,它会抛出这个错误:

    { [SequelizeUniqueConstraintError: Validation error]
  name: 'SequelizeUniqueConstraintError',
  message: 'Validation error',
  errors: 
   [ { message: 'id must be unique',
       type: 'unique violation',
       path: 'id',
       value: '1' } ],
  fields: { id: '1' } }

违规代码:

  db.Account.create({
    email: req.body.email,
    password: req.body.password,
    allowEmail: req.body.allowEmail,
    provider: 'local',
    role: 'user'
  })

通知ID未在任何地方指定,也未在我的模型定义中指定.如果我在postgres admin中运行它,它生成的查询运行正常:

INSERT INTO "Accounts" ("id","email","role","verifyCode","provider","cheaterScore","isBanned","allowEmail","updatedAt","createdAt") VALUES (DEFAULT,'cat69232@gmail.com','user','','local',0,false,false,'2016-01-27 04:31:54.350 +00:00','2016-01-27 04:31:54.350 +00:00') RETURNING *;

对于我在这里可能缺少的任何想法？

Postgres习惯在批量插入后不重置序列中的下一个数字(自动增量字段).因此,如果您在init例程或SQL转储文件中进行任何数据预填充,那可能就是您的问题.
