Attach action error in RelationManager

I am getting below error during Select search while performing Attach action in header of Relationship manager.

Call to undefined method App\Models\Setting\BusinessCategory::businessCategories()

Call to undefined method App\Models\Setting\BusinessCategory::businessCategories()

I have BusinessCategory model with N:N relationship with itself. My model has parents() and children() methods. Currently it is only two level. And I using using simple Attach action in the Header.

It's looking for the relationship businessCategories on the Model BusinessCategory

You probably need to define $inverseRelationship property when you have non-common relationship names

Agree. Hi @Dennis Koch . i tried

    public function scopeWithNoChildren(Builder $query): Builder
    {
        return $query->whereDoesntHave('children');
    }

    // Method to get categories with no children
    public static function businessCategories(): Builder
    {
        return self::withNoChildren();
    }

    public function scopeWithNoChildren(Builder $query): Builder
    {
        return $query->whereDoesntHave('children');
    }

    // Method to get categories with no children
    public static function businessCategories(): Builder
    {
        return self::withNoChildren();
    }

But i still get error Call to undefined method Illuminate\Database\Eloquent\Builder::getRelated(). I am writing custom Attach action now.

What's self in this context? Because this is not a relationship 🤔
