Populate versions when adding {versions: true} to an existing collection

I'll answer to my own issue here for others looking for it in future 😉

After adding

the admin panel for the collection is broken, since it tries to retrieve drafts of the documents.

AI-bot directs to non existing section of the documentation (

)

The solution I managed to do is to use the new migration feature and create required versions.

QUESTION TO THE PAYLOAD TEAM:

Should this be part of documentation and is my solution correct/optimal? If so, let me know where do you see it will fit and I can add it 😉

My solution

Run

And add content to the file

export async function up({ payload }: MigrateUpArgs): Promise<void> {
  const {docs} = await payload.find({ collection: 'posts' })
  for (const post of docs) {
    const VersionsModel = payload.db.versions['posts']
    await VersionsModel.create({
      parent: post.id,
      version: post,
      createdAt: post.createdAt ?? Date.now(),
      updatedAt: post.updatedAt ?? Date.now(),
      autosave: false,
      __v: 0,
      latest: true,
    })
  }
}

export async function down({ payload }: MigrateDownArgs): Promise<void> {
  const VersionsModel = payload.db.versions['posts']
  await VersionsModel.deleteMany({})
}
