dynamically embedding forms - symfony1

Question

I am trying to do add embedding forms dynamically using a single table in my schema.
What i mean by this is, in my sfGuardUserProfile table, I have numerous fields to determine what a user is, i.e. practice_id, nurse_id, patient_id
So, with that in mind, i am trying to dynamically add nurses to practices.
I have a practice form, that extends sfGuardUserAdminForm, which extends sfGuardUser, this is so i can get the username, password etc stored in the sfGuardUser table.
Within my practiceForm I am embedding a practiceProfileform, which displays the fields i need from the sfGuardUserProfile table. I hope everyone is following...
This works fine and I see the fields from both tables.
Now, the bit i am now unsure how to do: embedding the nurses. I am particularly unsure how to do this, as the practices and nurses are to be saved in the same table.
practiceForm
class Practiceform extends sfGuardUserAdminForm
{
public function configure()
{
$form = new PracticeProfileForm($this->getObject()->getProfile());
$this->embedForm('profile', $form);
}
}
I also have a nurseForm, which again extends sfGuardUser, embeds a nurseProfileForm, which extends sfGuardUserProfile to get the fields i need.
nurseForm
class dentistForm extends sfGuardUserAdminForm
{
public function configure()
{
$profileForm = new nurseProfileForm($this->object->Profile);
$this->embedForm('profile', $profileForm);
{
}
My schema.yml is as follows:
sfGuardUserProfile:
actAs:
Timestampable: ~
columns:
user_id:
type: integer(11)
notnull: true
default:
unsigned: false
primary: false
unique: false
autoincrement: false
email_new:
type: string(255)
unique: true
firstname:
type: string(255)
lastname:
type: string(255)
practice_id:
type: integer(11)
nurse_name:
type: varchar(255)
practice_name:
type: varchar(255)
practice_type:
type: varchar(255)
validate_at:
type: timestamp
validate:
type: string(33)
relations:
User:
class: sfGuardUser
foreign: id
local: user_id
type: one
onDelete: cascade
foreignType: one
foreignAlias: Profile
Practice:
class: sfGuardUserProfile
foreign: id
local: practice_id
type: one
onDelete: cascade
indexes:
validate:
fields: [validate]
Is there an easy way to achieve adding these nurses dynamically with the schema/forms i currently have using Doctrine/SF1.4?
Manay thanks

I would highly suggest to rethink your schema first. Do you really need to store all the entities in one table?
Instead, have different entities (classes) with their specific fields that relate to sfGuardUser. For example:
Nurse:
columns:
account_id: integer(4)
name: string(255)
...
relations:
Account:
class: sfGuardUser
local: account_id
foreign: id
type: one
foreignType: one
Then, you can embed Nurse relation in your sfGuardUserForm:
class sfGuardUserForm
{
public function configure()
{
$this->embedRelation('Nurse');
}
}
Or, the other way around:
class NurseForm
{
public function configure()
{
$this->embedRelation('Account');
}
}
And do the same for all the other entities. If you feel however, that your enities are pretty much the same, you can have a look at Doctrine's inheritance, though it is usually frowned upon.
