Include without 'count' and 'exists'

[ErfanBahramali]

Hii, good day,

I'm using a polymorphic relationship, and the inclusion of count and exists causes an error. I saw in the documentation a way to add only count or exists, but I couldn't find a way to add them without count and exists. I want to make sure that the items I add to allowedIncludes do not include count and exists.

Do I absolutely need to create a custom class, or is there another solution besides this?

Example:

taggable_type
taggable_id

Incorrect Query with taggableExists:

select `tickets`.*, exists(select * from `tickets` as `laravel_reserved_0` where `laravel_reserved_0`.`` = `laravel_reserved_0`.`taggable_id` and `laravel_reserved_0`.`deleted_at` is null) as `taggable_exists` from `tickets` where `laravel_reserved_0`.`deleted_at` is null

For example, it could be something like this:

$posts = QueryBuilder::for(Post::class)
    ->allowedIncludes([
        AllowedInclude::exact('taggable'), // only allows include the `taggable`
    ]);

I found this for this purpose:

use Spatie\QueryBuilder\AllowedInclude;
use Spatie\QueryBuilder\Includes\IncludedRelationship;

$posts = QueryBuilder::for(Post::class)
    ->allowedIncludes([
        AllowedInclude::custom('taggable', new IncludedRelationship(), 'taggable'),
    ]);
