Use refs or constructor data for rules?

[capopovici]

Hello,

Is there a way to use refs or constructor data in the standalone use?

The below code doesn't work, type error for this: Object is possibly 'undefined'

  public refs = schema.refs({
    today: luxon.utc().toISODate(),
  })

  @validate(schema.date({ format: 'yyyy-MM-dd' }, [rules.before(this.refs.today)]))
  public date: DateTime

Hello @capopovici ,

Thanks a lot for raising this issue.

Currently, there's no support for declaring schema refs in the class - in the future, I should be able to add support for this.

As a workaround, you can declare the refs outside & before the class declaration. Here is an example

// Declare the ref.
export const refs = schema.refs({
  countries: ["NG", "US"],
});


// Use the ref in the class schema.
class Register {
  @validate(schema.enum(refs.countries))
  public country!: string;
}

Other Limitations

There is a major limitation with respect to schema refs and the request context. Currently, you can't have access to the request context in the class decorator class validation. I'm yet to figure out a way to solve this. I have a "not too good" idea around this in mind, but I'll be very open to any suggestions.
