Research direction

The issue asks for generated JSON field types to be augmentable, similar to prisma-json-types-generator. Since no files are named, start by locating where ZModel Json? fields are converted into TypeScript types in the ZenStack codebase. Determine whether an extension point already exists; if not, the task is to design one so custom types can be attached to JSON fields and appear in generated query types. Done when a ZModel Json? field can be given a custom TS type like the union shown and that type flows into the generated client.

Written by the indexing model from the issue text.

Description

Similar to prisma-json-types-generated, I would like to augment the generated types to achieve proper type-safety when querying the data.

Example

zmodel

type Ruler {
  orientation String
  property1   String?
  property2   Json?
}

The "real" type

type IRulerLtr = {
  orientation: 'ltr'
  property1: string
}

type IRulerRtl = {
  orientation: 'rtl'
  property2: string | number
}

type IRuler = IRulerLtr | IRulerRtl
