我正在嘗試將用戶模型從 adonis 遷移到 postgres，但我不斷收到此錯誤Primary key value is missing for user我的模型看起來像這樣：class User extends Model {  static boot () {    super.boot()    this.addHook('beforeSave', async (userInstance) => {      if (userInstance.dirty.password) {        userInstance.password = await Hash.make(userInstance.password)      }    })  }  tokens () {    return this.hasMany('App/Models/Token')  }}module.exports = User我嘗試運行的遷移是：/** @type {import('@adonisjs/lucid/src/Schema')} */const Schema = use('Schema')class UserSchema extends Schema {  up () {    this.create('users', (table) => {      table.increments()      table.string('username', 80).notNullable().unique()      table.string('email', 254).notNullable().unique()      table.string('password', 60).notNullable()      table.timestamps()    })  }  down () {    this.drop('users')  }}module.exports = UserSchema我嘗試添加primary()假設table.increments()它正在 postgre 數據庫中生成自動增量 id。當我檢查數據庫時，有時會添加用戶，但 id 從 2 到 4 等等控制器看起來像這樣const User = use('App/Models/User')class UserController {  async register({request, auth, response}) {      const username = request.input("username")      const email = request.input("email")      const password = request.input("password")      let user = new User()      user.username = username      user.email = email      user.password = password      user = await user.save()      let accessToken = await auth.generate(user)      return response.json({"user": user, "access_token": accessToken})  }  async login({request, auth, response}) {    const email = request.input("email")    const password = request.input("password");    try {      if (await auth.attempt(email, password)) {        let user = await User.findBy('email', email)        let accessToken = await auth.generate(user)        return response.json({"user":user, "access_token": accessToken})      }    }    catch (e) {      return response.json({message: 'You first need to register!'})    }  }
