An example on how to embed forms in Symfony - symfony1

Question

I am using Symfony 1.3.2 with Propel ORM on Ubuntu 9.10.
I have a user profile table, which has many other tables linked to it (i.e. user_profile.id is a FK in many other tables.
My db schema looks something like this:
user_profile:
_attributes: { phpName: UserProfile }
id: ~
guard_id: { type: integer, foreignTable: sf_guard_user, foreignReference: id, required: true }
address: { type: longvarchar, required: true }
vehicle_type:
_attributes: { phpName: VehicleType }
id: ~
name: { type: varchar(32), required: true }
user_vehicle:
_attributes: { phpName: UserVehicle }
id: ~
user_id: { type: integer, foreignTable: user_profile, foreignReference: id, required: true }
vehicle_type: { type: integer, foreignTable: vehicle_type, foreignReference: id, required: true }
license_plate: { type: varchar(16), required: true }
user_child:
_attributes: { phpName: UserChild }
id: ~
user_id: { type: integer, foreignTable: user_profile, foreignReference: id, required: true }
gender: { type: boolean, required: true }
name: { type: varchar(32), required: true }
I would like to embed the other objects that link to the user profile object, in the user profile form, so that when I am performing CRUD on a user profile form, the related objects (e.g. UserVehicle, UserJob are also CRUD at the same time as the user profile object).
I need a simple snippet that will show how to:
Embed the various related objects (i.e. UserVehicle, UserChild) into the UserProfile form
Create/Update/Delete the various related objects as the operation is being carried (please note, a user can have more than 0-N vehicles or children assigned to them

Have you read the documentation?:
// lib/form/doctrine/ProductForm.class.php
public function configure()
{
$subForm = new sfForm();
for ($i = 0; $i < 2; $i++)
{
$productPhoto = new ProductPhoto();
$productPhoto->Product = $this->getObject();
$form = new ProductPhotoForm($productPhoto);
$subForm->embedForm($i, $form);
}
$this->embedForm('newPhotos', $subForm);
}
For the create/delete/update part, this article might give some help.

I never found the official approach right for my needs. I developed a completely different approach. In the company where I used to work we used in production this new approach, finding it a bit more elastic and simple. The key concept is "don't use Symfony's Form class and you will discover that embedding forms can be a very simple task"
I hope this can help you embedding forms.
