Updating fields in a Section when a Select is changed based on a relationship.

For context, this is part of a laboratory system. A doctor completes a requisition, which is captured into the system. The requisition belongs to a patient:

class Requisition extends Model implements Auditable
{
    public function patient(): BelongsTo
    {
    return $this->belongsTo(Patient::class);
    }
}

class Requisition extends Model implements Auditable
{
    public function patient(): BelongsTo
    {
    return $this->belongsTo(Patient::class);
    }
}

A patient has many requisitions:

class Patient extends Model implements Auditable
{
    public function requisition(): HasMany
    {
    return $this->hasMany(Requisition::class);
    }
}

class Patient extends Model implements Auditable
{
    public function requisition(): HasMany
    {
    return $this->hasMany(Requisition::class);
    }
}

I need the requisition creation form to be able to select a patient, or create a new one if it exists. This works:

Select::make('patient_id')
        ->label('Patient')
        ->relationship('patient', 'full_name')
        ->searchable(['full_name', 'id_number', 'pat_num'])
        ->createOptionForm(PatientResource::modal_form()) // Complete form for the modal
        ->createOptionModalHeading('Create Patient')
        ->suffixAction(
        Action::make('copy_to_guarantor')
        ->icon('heroicon-m-clipboard')
        ->action(function (Set $set, $state) {
        $set('guarantor_id', $state);
        })
        )
        ->required()
        ->live(),

Select::make('patient_id')
        ->label('Patient')
        ->relationship('patient', 'full_name')
        ->searchable(['full_name', 'id_number', 'pat_num'])
        ->createOptionForm(PatientResource::modal_form()) // Complete form for the modal
        ->createOptionModalHeading('Create Patient')
        ->suffixAction(
        Action::make('copy_to_guarantor')
        ->icon('heroicon-m-clipboard')
        ->action(function (Set $set, $state) {
        $set('guarantor_id', $state);
        })
        )
        ->required()
        ->live(),

In addition, once the patient is selected, it must be displayed so that it can be updated in case any information has changed. I have made the Select live() in the hopes that the chosen or created patient's data can be presented in thuis section for editing:

 Section::make()
        ->relationship('patient')
        ->schema(
        PatientResource::schema() // Array of patient fields
        )
        ->columns(2),

 Section::make()
        ->relationship('patient')
        ->schema(
        PatientResource::schema() // Array of patient fields
        )
        ->columns(2),

I am obviously not doing the thing properly, because the fields in the section do not respond to changes in the select at all. What do I need to do?

I have made a little progress. I have added a key to my Section:

Section::make()
    ->key('patient-details')
    ->relationship('patient')
    ->schema(
       PatientResource::schema() // Array of patient fields
    )
    ->columns(2),

Section::make()
    ->key('patient-details')
    ->relationship('patient')
    ->schema(
       PatientResource::schema() // Array of patient fields
    )
    ->columns(2),

and I have added a callback (taken from the docs) to the Select:

Select::make('patient_id')
  ->label('Patient')
  ->relationship('patient', 'full_name')
  ->searchable(['full_name', 'id_number', 'pat_num'])
  ->native(false)
  ->createOptionForm(PatientResource::modal_form()) // Complete form for the modal
   ->createOptionModalHeading('Create Patient')
   ->suffixAction(
     Action::make('copy_to_guarantor')
       ->icon('heroicon-m-clipboard')
       ->action(function (Set $set, $state) {
         $set('guarantor_id', $state);
       })
     )
     ->required()
     ->live()
     ->afterStateUpdated(fn (Select $component) => $component
       ->getContainer()
       ->getComponent('patient-details')
       ->getChildComponentContainer()
       ->fill()
     ),

Select::make('patient_id')
  ->label('Patient')
  ->relationship('patient', 'full_name')
  ->searchable(['full_name', 'id_number', 'pat_num'])
  ->native(false)
  ->createOptionForm(PatientResource::modal_form()) // Complete form for the modal
   ->createOptionModalHeading('Create Patient')
   ->suffixAction(
     Action::make('copy_to_guarantor')
       ->icon('heroicon-m-clipboard')
       ->action(function (Set $set, $state) {
         $set('guarantor_id', $state);
       })
     )
     ->required()
     ->live()
     ->afterStateUpdated(fn (Select $component) => $component
       ->getContainer()
       ->getComponent('patient-details')
       ->getChildComponentContainer()
       ->fill()
     ),

Now the patient details in the Section are emptied if I change the patient while editing the requisition. How do I get the actual Patient model to fill those fields with? Got it!

Select::make('patient_id')
  ->label('Patient')
  ->relationship('patient', 'full_name')
  ->searchable(['full_name', 'id_number', 'pat_num'])
  ->native(false)
  ->createOptionForm(PatientResource::modal_form()) // Complete form for the modal
   ->createOptionModalHeading('Create Patient')
   ->suffixAction(
     Action::make('copy_to_guarantor')
       ->icon('heroicon-m-clipboard')
       ->action(function (Set $set, $state) {
         $set('guarantor_id', $state);
       })
     )
     ->required()
     ->live()
     ->afterStateUpdated(fn (Select $component) => $component
       ->getContainer()
       ->getComponent('patient-details')
       ->getChildComponentContainer()
       ->fill(Patient::find($component->getState('patient_id'))->toArray())
     ),

Select::make('patient_id')
  ->label('Patient')
  ->relationship('patient', 'full_name')
  ->searchable(['full_name', 'id_number', 'pat_num'])
  ->native(false)
  ->createOptionForm(PatientResource::modal_form()) // Complete form for the modal
   ->createOptionModalHeading('Create Patient')
   ->suffixAction(
     Action::make('copy_to_guarantor')
       ->icon('heroicon-m-clipboard')
       ->action(function (Set $set, $state) {
         $set('guarantor_id', $state);
       })
     )
     ->required()
     ->live()
     ->afterStateUpdated(fn (Select $component) => $component
       ->getContainer()
       ->getComponent('patient-details')
       ->getChildComponentContainer()
       ->fill(Patient::find($component->getState('patient_id'))->toArray())
     ),
