Hi,

Just a quick update about Patient registration form functionality :

** Check duplicate : *

This function allow user to check for existing patient base on : name ,
birthdate, age, gender

If there is duplicate patient, a pop up will be showed, with the list of all
the duplicated patients.

>From this pop up, user can have two options :


   1. Continue create the current patient. So there will be two patients
   with the same information like above. But their  identifiers must be
   different which will be checked later.
   2. User can choose a patient from the list duplicated patient to update
   information for him, by click on the button "Update this patient" that
   follow by each patient in the list. User will then be redirected to the
   Update Patient page.

** Under age patient* :

Under age patient can be understand as a child. The purpose of this field is
not to hard code the age to define a child, like  age < 5  or age < 15.

In the registration form, there is a check box named " Is Underage" .  User
check on this check box to identify the patient is a child.  A pop up will
be showed after clicking.

The purpose of this pop up is :  user must choose a representative for this
child.  Because , some  identifiers that are mandatory ( can be defined in
Patient Identifier Type management page ) . But a child can not have those
identifier, so we have to inherit those identifier from the child's
representative.

Not all identifier can be inherited, you can defined a PatientIdentiferType
is able to inherit or not when creating it.  The field name is  "Related"
... ( God ...why didn't I use" Inheritable" .... ) .

If a PatientIdentifierType with "related" = FALSE and "mandatory" = TRUE
then user must enter value for it.

Ok, back to the popup, there are two tabs :

   1. Search existing person : user can search for an existing patient in
   system to be the representative of the child.
   2. Add new person : said this is person, because this is not really a
   patient, this person is just giving identifier...not enrolling to any
   program, at least at this step. Of course the record is also saved to the
   patient table. The form just only include basic information ( name ,
   birthdate, gender.. ) and Identifiers.  No attributes is needed. Of course
   user can update attributes for this person later by the Update Patient page.

One problem in this function that I can not have enough time to do :

In the combo box Relationship Type, there should be Parent and Guardian, I
hard coded this. You should create two relationship type  with this
information before testing this function :

   A is to B : Guardian, B is to A : Child
   A is to B : Parent , B is to A : Child.

The list of relationship type should be get from the Relationship type
table. But if we put everything to the combo box, then user may choose
Husband, Wife, or even child...which is so wrong.

My plan is creating an object RelationshipGroup, which should be based on
the age...

Anyway, because we are late for releasing this version in India. so hard
code for now is the only solution. I will continue working on this, so
...please don't worry...

** System generated identifier :*

I looked at the id_gen module from OpenMRS. Well , they have a whole module
for this which has many functionality for manage system auto generated
identifier.

I can not have enough time for getting all of that. So what I did is just
get a piece of code that is used for generate a check digit for the ID.

The format that Indian team chose is :
[BirthDate][Gender][XXXXXX][checkdigit]

BirthDate : yyyyMMdd
Gender : Male  = 1 ; Female = 0
XXXXXX : a random number  with length = 6   ( 0 - 999999 )
checkdigit :  generated using Luhn Algorithm ( thanks to OpenMRS guys )

I also changed the way that Abyot generate the birthdate from age ( when
user only enter age ) .
It is :    todayCalendar.add( Calendar.YEAR, -1 * age );
What Abyot did is
          todayCalendar.set( Calendar.DATE, 1 );
          todayCalendar.set( Calendar.MONTH, Calendar.JANUARY );
          todayCalendar.add( Calendar.YEAR, -1 * age );
Because we generate the id base on birthdate , get current date should be
better.
Hope this is ok for Abyot....

Each country will have different formats...so I think for current we just
can change code when implementing in the country. Building a module for this
would take time....

Finally,  but almost those things only follow India 's requirements.
Please give comment then we can try to make it more generic...
