How to modify related objects before 'replace' when send as PATCH

[mk-conn]

Hi,

when I try to use replacing hook I only get the record and not the related objects, I just wanna add some default data (e.g. the logged in user as created_by, updated_by properties...). Is there another way - maybe overwriting the Adapter 'replace' methods, but would be the controller hooks not the place to do so?

Hi! What do you mean by the 'replacing' hook?

Personally I put stuff like this in the adapter, as the adapter is the thing that fills the model with values from the JSON API resource, so it makes sense to do any other fill logic there.

Maybe use the persist method like this:

protected function persist($record)
{
  if ($record->exists) {
    $record->updatedBy()->associate(Auth::user());
  } else {
    $record->createdBy()->associate(Auth::user());
  }

  $record->save();
}

I mean the Relationship Hooks in the controller as documented here: https://laravel-json-api.readthedocs.io/en/latest/basics/controllers/ , escpecially the replacing{Field} Hook.

Ah right I'm with you now - sorry I didn't realise that from your first post.

The related records are not materialised at that point, but it would be useful if you could choose to look them up in those hooks. For that I'd need to pass the JSON API store to the hooks, and add some documentation so that it was clear how to do it. I think that would be a useful addition so I'll add it to the to-do list.

Great :) Thx!

As this is quite old, I'm closing in favour of the issue in the new package (laravel-json-api/laravel), where this will be straight-forward to implement.
