在主關係領域

Question

我有一個主關係領域的VF頁自動插入，我可以在此字段中插入值自動

<apex:inputField value="{!a.Parent__c}"/> 

Answer 1

問題有點含糊，但如果你想設置的默認值對於Parent__c，您只需將值應用於控制器類。

例

public class VFController { 
private Account controllerAccount; 

//Basic Constructor 
public VFController() { 
    controllerAccount = new Account(); 
    controllerAccount.Parent__c = getDefaultParentAccount();  
} 

//Standard Controller Constructor 
public VFController(ApexPages.Controller standardController) { 
    controllerAccount = (Account)standardController.getRecord(); 
    controllerAccount.Parent__c = getDefaultParentAccount(); 
} 

private Id getDefaultParentAccount() { 
    Id parentAccountId = null; 

    //Lookup default parent Account 
    List<Account> parentAccounts = [SELECT Id FROM Account WHERE /*Your Criteria here*/ LIMIT 1]; 
    if (parentAccounts.isEmpty() == false) { 
     parentAccountId = parentAccounts[0].Id; 
    } 

    return parentAccountId; 
} 

}
