How to save users using PostgreSQL

For the historical record; This issue has been resolved by Diana Lau as following:

1. Create User & UserCredentials for integrating JWT

$ lb4 model User
? Please select the model base class Entity (A persisted model with an ID)
? Allow additional (free-form) properties? No
Model User will be created in src/models/user.model.ts

Let's add a property to User
Enter an empty property name when done

? Enter the property name:
   create src/models/user.model.ts
   update src/models/index.ts

Model User was/were created in src/models

$ lb4 model UserCredentials
? Please select the model base class Entity (A persisted model with an ID)
? Allow additional (free-form) properties? No
Model UserCredentials will be created in src/models/user-credentials.model.ts

Let's add a property to UserCredentials
Enter an empty property name when done

? Enter the property name:
   create src/models/user-credentials.model.ts
   update src/models/index.ts

Model UserCredentials was/were created in src/models

2. Replace models/user.model.ts & models/user-credentials.model.ts by user.model.ts & user-credentials.model.ts

3. Create repositories for User and UserCredentials

$ lb4 repository
? Please select the datasource PostgresqlDatasource
? Select the model(s) you want to generate a repository for UserCredentials, User
? Please select the repository base class DefaultCrudRepository (Juggler bridge)
? Please enter the name of the ID property for UserCredentials: id
? Please enter the name of the ID property for User: id
   create src/repositories/user-credentials.repository.ts
   create src/repositories/user.repository.ts
   update src/repositories/index.ts
   update src/repositories/index.ts

Repositories UserCredentialsRepository, UserRepository was/were created in src/repositories

4. Run npm run build

5. Modify datasources/postgresql.datasource.ts to meet the proper PostgreSQL configurations then create a new PostgreSQL database depending on your configurations.

6. Run npm run migrate

7. Delete the following files:

• models/user.model.ts
• models/user-credentials.model.ts
• repositories/user.repository.ts
• repositories/user-credentials.repository.ts

8. Modify models/index.ts by deleting the following lines:

export * from './user.model';
export * from './user-credentials.model';

9. Modify repositories/index.ts by deleting the following lines:

export * from './user-credentials.repository';
export * from './user.repository';

NOTE: I suggested a new feature request for a better JWT integration in this issue.
