jd123 How can we add fields dynamically to the child Object based on parent object input?
Hi Everyone,
my requirement is i have two objects, 1.Stattfing_Plan (Parent) 2. Staffing_Resorces__c(Child)
Staffing plan is estimation to complete the Project (project is have only one Staffing plan).Staffing plan have multiple Staffing resources (Employees).
if suppose in my parent object (Staffing_Plan__c) i have given Start_Date__c 11/26/2012 and weeks is 5.
then for all recosures dynamically i should add 5 input text or fields dynamically for all child records fo Staffing_Pan__c
like this
Staffing_Pan__c
Start_date__c -----11/26/2012
weeks---------------3
child records (page block table)
----------------
Name 11/26/2012 12/04/2012 12/11/2012
--------------------------------------------------------------------------------------------------------------------------------------------------------
mahender inputtext inputtext inputtext
surender inputtext inputtext inputtext
nareder inputtext inputtext inputtext
like it should create and when i am saving these values it should save in the database.
There are several ways to approach this problem. Here are a few:
The easy, but slightly less elegent, but supported by Salesforce way: Create another custom object, say staffing_resources_weeks__c and write a trigger to insert the appropriate number of weeks upon the creation of each staffing_resource_record. You could then create a custom VF page for the staffing resource that would display the data the way that you expect.
Another way: Hack the salesforce METADATA API WSDL so that you can load it into APEX (this is not supported natively by Salesforce). I have never done it, but I have seen people claim this is possible. Then use it like you want to and add the fields dynamically.
Finally, add 52 "week" fields to the staffing_resource__c object. Create a custom VD page that displays the correct number of weeks and a trigger that populates the fields correctly. A limitation on this is that a project could take at most one year. Longer projects would have to be split up.
I can give you more information on any of these options if you are interested.
Hi Jake,
Really very good expalanationThanks Jake.
I think the third one is easy to implement it.Would you please send me some sample code how can i do it but it won't support if weeks are more than 52.
ca you send some sample code for frist one also.
So even the third method requires a bit of coding but here is the idea:
Apex:
Public class myController{
boolean showField {get; set;}
public myController(){
showField = True;
}
}
<apex:Page controller = myController>
<apex:outputField value = {!myObj.myField1__c} rendered = {!showField} />
....
So there has to be alot more there obviously, but that should give you an idea on how to go forward. As goes the showField value, then that field will be displayed or not displayed. You could do it manually by having a boolean for each field, but a slicker way would be to use getDescribe to get the field names and use a comparison to show or not shoe the field. Let me know if you have specific questions on this.
