HasOne Relationship Question

[bendulum]

When a user signs up with my app he can create either a personal or a business profile.

Three types of models exist in the code:

• User (general sign-up information)
• Person (personal information, only applies to personal accounts)
• Business (business information, only applies to business accounts)

So the User model can have a HasOne relationship to a Person model, OR a Business model, but not both.
Having trouble to implement this. Maybe there is a flaw in my database schema design.

Schema of persons table has:

table
    .integer('user_id')
    .notNullable()
    .references('users.id')
    .onDelete('CASCADE')

Schema of businesses table has the same:

table
    .integer('user_id')
    .notNullable()
    .references('users.id')
    .onDelete('CASCADE')

Both models have:

@column()
declare userId: number

I would like to avoid introducing an extra pivot table for this. What is the correct way of implementing this?

EDIT

I have come across the inherits feature of Lucid https://lucid.adonisjs.com/docs/table-builder#inherits

this.schema.createTable('capitals', (table) => {
  table.inherits('cities')
})

... but it's lacking a bit of documentation, and I'm unsure of the implications of using it.
