Generating realistic example values

Library Version(s)

1.1.11

Problem

I'm experimenting with compojure-api for documenting a new set of APIs with Prismatic Schema. It;s working well so far, though I have one issue which is not obvious how to resolve - how to generate realistic example values for an input / output schema.

Currently I get Example Values in the swagger UI like this:

{
  "name": "string",
  "description": "string",
  "type": "assetClass1",
  "ownerID": "string"
  "dateCreated": "2018-11-19T01:25:04.282Z",
}

In this case, I need ownerID to be a 64 character hex string which satisfies a custom valid-user-id? predicate, which defined in Schema as something like:

(s/defschema UserID
  (s/constrained s/Str valid-user-id? "Valid User ID"))

However it's not clear how to get compojure-api to generate valid values which satisfy the constraint (The value "string" doesn't....) and display these to the user in the Swagger UI.

Is there a way to do this? Ideally I would like to be able to specify a custom generator for the schema, which I build easily enough with test.check but how do I get that to be reflected in the Swagger UI?

Any help much appreciated!

Beginne damit nachzuverfolgen, wie Prismatic Schema-Definitionen zu Beispielwerten für Swagger UI werden, und vergleiche diesen Pfad anschließend mit dem mithilfe von test.check beschriebenen benutzerdefinierten Generator. Das Issue ist abgeschlossen, wenn ein Schema realistische Werte liefern kann, die die Constraints erfüllen, und diese Werte in den generierten Swagger UI-Beispielen erscheinen.
