Validator Adonisjs 6

[LeFlow]

hi.

I have a "posts" table which contains a foreign key corresponding to the ID of the "categories" table so 2 models

import { DateTime } from 'luxon'
import { BaseModel, belongsTo, column } from '@adonisjs/lucid/orm'
import type { BelongsTo } from '@adonisjs/lucid/types/relations'
import Category from './category.js'

export default class Post extends BaseModel {
  @column({ isPrimary: true })
  declare id: number

  @column()
  declare title: string

  @column()
  declare content: string

  @column()
  declare online: boolean

  @column()
  declare thumbnail: string | null

  @belongsTo(() => Category)
  declare categry: BelongsTo<typeof Category>

  @column()
  declare categoryId: number

  @column.dateTime({ autoCreate: true })
  declare createdAt: DateTime | null

  @column.dateTime({ autoCreate: true, autoUpdate: true })
  declare updatedAt: DateTime | null
}

and

import { DateTime } from 'luxon'
import { BaseModel, column } from '@adonisjs/lucid/orm'

export default class Category extends BaseModel {
  @column({ isPrimary: true })
  declare id: number

  @column()
  declare name: string

  @column.dateTime({ autoCreate: true })
  declare createdAt: DateTime

  @column.dateTime({ autoCreate: true, autoUpdate: true })
  declare updatedAt: DateTime
}

I'm trying to make a "postValidator".
A priori, on Adonisjs 5, the code is:

  public shema = schema.create({
    title: schema.string({trim: true}, [
      rules.minLength(5)
    ]),
    categoryId: schema.number([
      rules.exists({column: Category.primaryKey, table: Category.table})
    ])
    content: schema.string({trim: true}),
    online: schema.boolean().nullableAndOptional
  })

But on Adonis 6, it's not the same.
I tried to do

import Category from '#models/category'
import vine from '@vinejs/vine'

export const PostValidator = vine.compile(
  vine.object({
    title: vine.string().trim().minLength(6),
    content: vine.string().trim().escape(),
    online: vine.boolean().nullable().optional(),
  })
)

which works
But when, to validate the category linked to the post, I added :
categoryId: vine.number().exists( Category.table, Category.primaryKey )
following : online: vine.boolean().nullable().optional(),
It dont work
It shows me that none of the form fields are valid.
My IDE displays the message: : Expected 1 arguments, but got 2.

Hey @LeFlow! 👋🏻

Where did you see this syntax?

categoryId: vine.number().exists( Category.table, Category.primaryKey )

[LeFlow]

Nowhere, it's just an (unsuccessful) attempt on my part :(

You can try creating custom rules for it.
