Steps to reproduce

1. Intstall @loopback/authentication @loopback/authentication-jwt extensions

2. Suppose you are using Relational database, using the constraints as foreign keys, so you to sequence the model in migrate.ts as guided on #link1 above like
   models:[...model, ...relatedmodel]
   **Note if you dont have key constraints and this model sequencing, it work fine. no error

3. Then bind the authentication-jwt datasource in to your application.ts
   this.datasource(YourDbDatasource, UserServiceBindings.DATASOURCE_NAME)

4. when you run migrate.
   `

npm run clean
npm run build
npm run migrate
`

Error Come in action
Cannot migrate database schema Error: Cannot migrate models not attached to this datasource:

まず migrate.ts と application.ts から始め、authentication-jwt datasource をバインドした後、npm run clean、npm run build、npm run migrate を実行して報告された失敗を再現します。シーケンス化されたモデルが未アタッチとして報告される理由を追跡し、文書化された relational-model のセットアップがそのエラーなしにマイグレーションできた時点で issue は完了とします。
