How do I make a form field not neccessray for validation in Symfony?

I have 2 forms: $patientForm and $investigationForm.

They are both combined into one view, so the user fills in the fields and 2 records are created in Patient table and Investigation table. Investigation table has a foreign key - to the patient name. So one patient can have many investigations.

So I obviously need the patient id to add it to an investigation record as a foreign key. However, the patient id isn't created until the patient form is saved.

So I have devised the following function:

protected function processPatientInvestigation(sfWebRequest $request, sfForm $investigationForm, sfForm $patientForm)
{
    $patientForm->bind($request->getParameter($patientForm->getName()), $request->getFiles($patientForm->getName()));

    if ($patientForm->isValid() && $investigationForm->isValid() ) {        
        $patientForm->save();       
        $values = $request->getParameter($investigationForm->getName());
        $values['patient_id'] = $patientForm->getObject()->getId();
        $investigationForm->bind($values, $request->getFiles($investigationForm->getName()));
        $investigationForm->save();     
    }

The if statement always fails because $investigationForm isn't valid until I give its form field a patient_id value. So this value is empty at this point. However, if I just took the isValid() check out for $investigation form and put it down later on after the $patientForm is saved. This means that if it failed validation and the user had missed a field, when they don't click submit again, the whole function would run again meaning we'd have duplicate patient records.

So what I think the answer is, is making the patient_id field not be validated, so it can be empty and still pass the isValid() function.

Please let me know if this isn't clear. Hope you can advise!

I'd go with embedded forms and let symfony handle the saving correctly.

The cleaner solution would be to set all your validation rules in the /lib/form/*Form.class.php file itself (rather than manipulating it in your action).

$this->validatorSchema['patient_id'] = new sf*Validator(array(
  'required' => false
), array());

If you just want to let a form field completely unvalidated, use 

$this->validatorSchema['patient_id'] = sfValidatorPass()

Try the following though this should really be done in the forms configure method.

$patientForm->getValidator('patient_id')->addOption('required', false);
