{
    return $this->belongsTo(Category::class, DB::raw("ANY(category_id)"), 'id');
}

no get category is null.

Answer

I can’t relation but with attribute i can get categories

firstly cast category_id to array and

public function getCategoriesAttribute()
{
    return Category::whereIn('id',$this->category_id)->get();
}
