[QUESTION] Conditional validation in Model

Hello!

Does Ts.ED provide a way to perform a conditional validation of a model based on another field in the model? Consider the following example

export enum Buyer {
  Person = "PERSON",
  Company = "COMPANY"
}

export class Invoice {
  @Required()
  @Enum(Buyer)
  buyer: Buyer;

  @Optional()
  // I'd like this field to be required only if buyer === 'COMPANY'
  companyData?: CompanyData

  @Optional()
  // ... and this field should be required only if buyer === 'PERSON'
  // something like:
  // @RequiredIf(o => o.buyer === 'PERSON')
  personData?: PersonData
}

For the record, it doesn’t really matter for me if this requirement is reflected in JSON Schema (both fields can be optional), I’m only caring about validation of request.

I decided to just extend JsonSchemaObject like this:

declare module "@tsed/schema" {
  interface JsonSchemaObject {
    if?: Partial<JsonSchemaObject>;
    then?: Partial<JsonSchemaObject>;
    else?: Partial<JsonSchemaObject>;
  }
}

No more complains 😃
