Call to undefined method Illuminate\Database\Eloquent\Relations\BelongsToMany::getOwnerKeyName()

Hi there! Created a simple BelgonsToMany relationship like in Laravel Documentation(https://laravel.com/docs/10.x/eloquent-relationships#many-to-many-defining-the-inverse-of-the-relationship) and I've got the following error:

Call to undefined method Illuminate\Database\Eloquent\Relations\BelongsToMany::getOwnerKeyName()

Call to undefined method Illuminate\Database\Eloquent\Relations\BelongsToMany::getOwnerKeyName()

I've used the example from the FIlament documentation for creating a Select:

 Forms\Components\Select::make('projects')
                    ->relationship('projects', 'name'),

 Forms\Components\Select::make('projects')
                    ->relationship('projects', 'name'),

guess you called the value before "getOwnerKeyName()" as a method, not as a value? I am guessing it was a user.. call user->getOwnerKeyName() calling it as a method will return the relation, not the instance

I did not called it. The only place where I used the relationship is in this piece of code:

 Forms\Components\Select::make('projects')
                    ->relationship('projects', 'name'),

 Forms\Components\Select::make('projects')
                    ->relationship('projects', 'name'),

One moment

class Apartment extends Model
{
    //
    public function projects(): BelongsToMany
    {
        return $this->belongsToMany(Project::class);
    }
}

class Apartment extends Model
{
    //
    public function projects(): BelongsToMany
    {
        return $this->belongsToMany(Project::class);
    }
}

class Project extends Model
{
    use HasFactory;

    public function apartments(): BelongsToMany
    {
        return $this->belongsToMany(Apartment::class);
    }
}

class Project extends Model
{
    use HasFactory;

    public function apartments(): BelongsToMany
    {
        return $this->belongsToMany(Apartment::class);
    }
}

class ApartmentProject extends Pivot
{
}

class ApartmentProject extends Pivot
{
}

Schema::create('apartment_project', function (Blueprint $table) {
            $table->id();

            $table->foreignId('apartment_id');
            $table->foreignId('project_id');

            $table->timestamps();
        });

Schema::create('apartment_project', function (Blueprint $table) {
            $table->id();

            $table->foreignId('apartment_id');
            $table->foreignId('project_id');

            $table->timestamps();
        });

getting the same error now @alexmanase I do not know the fix, seems like a bug.. but you could use this workaround:

Select::make('apartments')
    ->options($this->project->apartments->pluck('name', 'id')->toArray())

Select::make('apartments')
    ->options($this->project->apartments->pluck('name', 'id')->toArray())

or the other way around with projects, does not make a difference

Thanks! I know that, but I need to create a new relationship model from the select.

->createOptionForm([
                     Forms\Components\TextInput::make('name')
                         ->required(),
                ]),

->createOptionForm([
                     Forms\Components\TextInput::make('name')
                         ->required(),
                ]),

Like this. I'll make an issue to the Filament repo Thanks for your help.

I don’t think you can use a many to many on a select without making it multiple. Might also need 'withPivot' on your relationships
