更新 Apex 程式碼中的層次結構自定義設定
你可能希望在執行程式碼期間更新自定義設定，以關閉驗證或工作流程規則。
在下面的程式碼中，我建立了一個可排程 Apex 類 ，它將更新其關閉日期小於或等於當前日期 6 天的任何商機的關閉日期，將日期更改為 20 天。
我將使用我的自定義設定 Val_Rule_Cntrlr__c 來停用任何驗證規則，這將阻止我更新符合我的條件的商機。
global class Scheduled_OppCloseDateUpdate implements Schedulable {
global void execute(SchedulableContext SC) {
updOpportunityCloseDates();
}
global void updOpportunityCloseDates() {
Id userId;
Val_Rule_Cntrlr__c setting;
Boolean validationRulesAlreadyDisabled;
List<Opportunity> processedOpps = new List<Opportunity>();
Date d;
// get running user's Id
userId = userinfo.getUserId();
// retrieve Custom Setting status, for running user
setting = Val_Rule_Cntrlr__c.getInstance(userId);
// if the setting field is false, update it to disable validation rules
if (setting.All_Opportunity_Disabled__c == false) {
setting.All_Opportunity_Disabled__c = true;
upsert setting;
}
// if the setting field was already true, there's no need to disable it
// but it shouldn't be switched to false by this class once the process has been completed
else {
validationRulesAlreadyDisabled = true;
}
// execute code to manage business process
d = system.today().addDays(6);
for(Opportunity o : [SELECT Id, CloseDate
FROM Opportunity
WHERE CloseDate <= :d
// class only updates open Opportunities
AND Probability > 0 AND Probability < 100])
{
o.CloseDate = System.today().addDays(20);
processedOpps.add(o);
}
if (processedOpps.size() > 0) {
update processedOpps;
}
// reactivate validation rules
if (validationRulesAlreadyDisabled == false) {
setting.All_Opportunity_Disabled__c = false;
upsert setting;
}
}
}
為了確保我的類中的自定義設定更改停用了我的驗證規則，我建立了一個核取方塊欄位 Trigger_Validation_Rule__c（使用者無法看到或新增到頁面佈局中）和帶有此條件的驗證規則：
AND(
$Setup.Val_Rule_Cntrlr__c.All_Opportunity_Disabled__c = FALSE,
Trigger_Validation_Rule__c = TRUE,
/* allow the above criteria to be met while inserting the Opportunities, without triggering the rule, in the @testSetup portion of the test */
NOT(ISNEW())
)
然後，在建立機會時，我將核取方塊欄位設定為 true，以便在我的程式碼不編輯自定義設定欄位時滿足規則標準。
@isTest
private class WE_ScheduledCloseDateUpdateTest {
@testSetup
static void dataSetup() {
Profile p = [SELECT Id FROM Profile WHERE Name = 'System Administrator' LIMIT 1];

insert u;
Val_Rule_Cntrlr__c valRuleCntrlr = new Val_Rule_Cntrlr__c(SetupOwnerId = u.Id,All_Opportunity_Disabled__c = false);
upsert valRuleCntrlr;
List<Opportunity> testOpps = new List<Opportunity>();
// create the Opportunities that will be updated by the class
for(integer i = 0; i < 200; i++) {
testOpps.add(new Opportunity(
Name = 'Test Opp Update' + i,
OwnerId = u.Id,
StageName = 'Prospecting',
CloseDate = date.today().addDays(1),

// set checkbox field to true, to trigger validation rules if they've not been deactivated by class
