hlotte Get data from parent object
Hi,
I'm totally newbie on Sales force, and I'm trying something that should be easy.
From a Case, I want to manage a new type of object, named SMS
I created the object and now I want to customize the page, with APEX
So, I created a class
global class NetsizeClass
{
private SMS__c currentSms;
public SMS__c getSms()
{
return currentSms;
}
public NetsizeClass(ApexPages.StandardController controller)
{
if (currentSms == null)
currentSms = new SMS__c();
string sms_id = System.currentPageReference().getParameters().get('id');
if (sms_id == null || sms_id == '')
{ // New SMS
currentSms.message__c = 'New SMS ';
}
else
currentSms= [select message__c, status__c, case__c, contact__c
from SMS__c where id = :sms_id];
}
public void SendSMS()
{
if (currentSms.id == null || currentSms.id == '')
// New SMS
else
// Existing SMS
upsert currentSms;
...
}
}
and a Page, that overload the 'New' button in my SMS object
<apex:page standardController="SMS__c" extensions="NetsizeClass"> <apex:sectionHeader title="New SMS" subtitle=""/> <apex:form> <apex:pageBlock title="SMS information"> <apex:pageBlockButtons > <apex:commandButton value="Save" action="{!save}"/> <apex:commandButton value="Send SMS" action="{!SendSMS}"/> </apex:pageBlockButtons> <TABLE> <TR> <TD><B>Message</B></TD> <TD><apex:inputField value="{!sms.Message__c}" id="smsMsg"/></TD> </TR> <TR> <TD><B>Contact</B></TD> <TD><apex:inputField value="{!sms.Contact__c}" id="smsContact"/></TD> </TR> <TR> <TD><B>Case</B></TD> <TD><apex:inputField value="{!sms.Case__c}" id="smsCase"/></TD> </TR> <TR> <TD><B>Case 2</B></TD> <TD><apex:inputField value="{!SMS__c.Case__c}" id="smsCase2"/></TD> </TR> </TABLE> <br/> </apex:pageBlock> </apex:form> </apex:page>
It works fine, when I am on a Case, I see the button 'New SMS' (I customized the layout), that open my custom APEX page.
But I just don't know how to retreive the parent Case information (I'm using the 2 fields Case for my tests):
- the field smsCase is empty, and it's normal as it is linked to {!sms.Case__c} and sms is created in the constructor. But I read in some forums that it's the only way to retreive later the updated values (I want to customize the Edit and View page)
- the field smsCase2 is filled with the id of my Case, but I don't know how to retreive this data from my page.
I also would like to retreive automatically the contact linked in the parent Case, to link it to the SMS. But I think it should be easy to do when I'll have the ID of my Case.
I'm sure that I'm missing something but I searched in so much forums that I'm starting to mix-up everything.
Any help will be welcome :)
Thanks
Hervé
Hey
This field,
<apex:inputField value="{!SMS__c.Case__c}" id="smsCase2"/>
Is using the standard controller's instance of the object. Whereas this field,
apex:inputField value="{!sms.Case__c}" id="smsCase"/>
Is using your extensions instance of the object. You need to link the two. This can be done more or less like this,
(sorry about the code getting squashed up. When I click 'Post' it scrunches it up.)
global class NetsizeClass{ private SMS__c currentSms; public SMS__c getSms() { return currentSms; } public NetsizeClass(ApexPages.StandardController controller) { currentSms = (Sms__c)controller.getSubject(); // this get's the object that the standardcontroller is working with. It links the extension and standardcontroller(sortof) if (currentSms.id == null || currentSms.id == '') { // New SMS currentSms.message__c = 'New SMS '; } else currentSms= [select message__c, status__c, case__c, contact__c from SMS__c where id = :sms_id]; } public void SendSMS() { if (currentSms.id == null || currentSms.id == '')// New SMS
else
// Existing SMS
upsert currentSms;
... }
}
On your page, try to not mix {!SMS__c.field} and {!sms.field}. I know you're probably doing some troubleshooting, but just for future reference;) Otherwise saving can get tricky.
Cheers,
Wes

Wonderful, it's exactly what I was looking for ! :)
I didn't think to have a look to the 'controller' object. I'm going to check its property right now.
Don't worry, I'll remove the field linked to {!SMS__c.field}. I was using it just for my tests.
Thanks a lot for your quick support !! :D
