Is it possible to seed nested referenced entities?

If I have three tables with a one to many relations: Agency -> Project -> Domain I see in the docs that with refine you can create references from one table to another:

await seed(db, schema).refine(f => ({
  agency: {
    count: 3,
    with: {
      project: 4
    }
  }
}))

await seed(db, schema).refine(f => ({
  agency: {
    count: 3,
    with: {
      project: 4
    }
  }
}))

But I would also like to create references to domains, however I cannot keep nesting after project. How to create relationships between project and domain, so the project refers to an agency?

Validate Record values with morphs

Is it possible to do more advanced validation on Records? Ideally I'd like to apply any morph to each item in a Record.

const nullNumber = type('number').pipe((s) => s ? Number(s) : null);

const obj = type({
  searches: 'Record<string, ???>'
});

const nullNumber = type('number').pipe((s) => s ? Number(s) : null);

const obj = type({
  searches: 'Record<string, ???>'
});

In the ??? place, I'd like to validate against nullNumber, is it possible?

Testing a type in pipe

Congratulations on the 2.0 release, it's working great! 😀 Is it possible/best practice to run a type inside pipe? I'm having this test condition:

If string is a valid url, return URL
Else return null

If string is a valid url, return URL
Else return null

I'm not sure of the best way to handle this scenario with morphs? I see there's a second parameter for pipe.try, can it be used to simplify?

Problem with validation in 2.0 dev?

I'm using 2.0.0-dev.11 and cannot figure out why some very basic validation fails. Short example:

import { type } from "arktype";

const nospacePattern = /^\S*$/;

const schema = type({
  name: "string",
  email: "email",
  tags: "(string>=2)[]>=3",
  score: "integer>=0",
  "date?": "Date",
  "nospace?": nospacePattern,
  extra: "string|null",
});

const data = {
  name: "Ok",
  email: "",
  tags: ["AB", "B"],
  score: -1,
  date: undefined,
  nospace: "One space",
};

const out = schema(data);

console.log("nospace matches:", nospacePattern.test(data.nospace));

if (out instanceof type.errors) {
  console.log(out.summary);
} else {
  console.log(out);
}

import { type } from "arktype";

const nospacePattern = /^\S*$/;

const schema = type({
  name: "string",
  email: "email",
  tags: "(string>=2)[]>=3",
  score: "integer>=0",
  "date?": "Date",
  "nospace?": nospacePattern,
  extra: "string|null",
});

const data = {
  name: "Ok",
  email: "",
  tags: ["AB", "B"],
  score: -1,
  date: undefined,
  nospace: "One space",
};

const out = schema(data);

console.log("nospace matches:", nospacePattern.test(data.nospace));

if (out instanceof type.errors) {
  console.log(out.summary);
} else {
  console.log(out);
}

The output I get from running this is:

nospace matches: false
email must be a valid email (was "")        
extra must be a string or null (was missing)
date must be a Date (was undefined)

nospace matches: false
email must be a valid email (was "")        
extra must be a string or null (was missing)
date must be a Date (was undefined)

I'd expected errors for score, nospace, tags and maybe tags[1] as well. Anything very simple I'm missing?

Using parameter in LIKE

Is it safe to pass a string directly into a like condition, or does it have to be quoted or parameterized somehow?

where(like(entries.text, `%${filters.search}%`))

where(like(entries.text, `%${filters.search}%`))

Array error message

Hello, I think I found an inconsistency in array errors: https://stackblitz.com/edit/vy55da?file=type.ts The tags error is: tags must be at least 3 characters (was 2) But should probably not be characters, but something like items.
