Creating Discriminators

/* module: person.ts */

import { GtDocument, GtModel, GtColumn, GtDiscriminator } from '@pebula/goosetyped';

@GtDocument()

export class Person<T extends string> extends GtModel() {

@GtColumn() name: string;

@GtColumn() age: number;

@GtDiscriminator()

type: T;

}

import { GtDocument, GtModel, GtColumn } from '@pebula/goosetyped';

import { Person } from './person';

@GtDocument()

export class BusinessMan extends Person<'BusinessMan'> {

@GtColumn() businessTrips: number;

}

@GtDocument()

export class Soldier extends Person<'Soldier'> {

@GtColumn() releaseDate: Date;

}

@GtDocument()

export class Athlete extends Person<'Athlete'> {

@GtColumn() medals: number;

}

tip

Sub Documents are also valid discriminators.

Discriminators as Sub Documents

import { GtDocument, GtModel, GtColumn } from '@pebula/goosetyped';

import { Person } from './person';

@GtDocument()

export class SalesLead extends GtModel() {

@GtColumn() receivedAt: Date;

@GtColumn({ type: () => Person })

person: BusinessMan | Soldier | Athlete;

}

import { GtDocument, GtModel, GtColumn, DocumentArray } from '@pebula/goosetyped';

import { Person } from './person';

@GtDocument()

export class Course extends GtModel() {

@GtColumn() name: string;

@GtColumn() startDate: Date;

@GtColumn({ type: () => Person })

students: DocumentArray<BusinessMan | Soldier | Athlete>;

}
