Apex Comparator compare multiple object fields

Sorting a list of Analysis messages first by boolean and then integer. First we will order by condition and then order. All records where condition is true is will be on top in descending order on top followed by all false condition in descending order.

SummaryAnalysisMessages object to sort

public class SummaryAnalysisMessages {
		private String title;
		private String description;
		private Integer order;
		private Boolean condition;

		public SummaryAnalysisMessages(String title, String description, Integer order, Boolean condition){
			this.title = title;
			this.description = description;
			this.order = order;
			this.condition = condition;
		}

		public Boolean getCondition(){
			return condition;
		}

		public Integer getOrder(){
			return order;
		}
	}

Compare object by condition and then order

public class SummaryAnalysisMessagesCompare extends App_Comparator {
    public override Integer compare(Object a, Object b) {
			SummaryAnalysisMessages aSummaryMessage = (SummaryAnalysisMessages)a;
			SummaryAnalysisMessages bSummaryMessage = (SummaryAnalysisMessages)b;

      Integer summaryMessage1 = aSummaryMessage.getCondition() ? 1 : 0;
      Integer summaryMessage2 = bSummaryMessage.getCondition() ? 1 : 0;

			Integer compareInt = summaryMessage2 - summaryMessage1;
      if (compareInt == 0) {
          compareInt = aSummaryMessage.getOrder() - bSummaryMessage.getOrder();
      }
      return compareInt;
    }
}

Test class to test order

@isTest static void testSummaryAnalysisMessagesCompare(){
		SummaryAnalysisMessages summaryAnalysisMessage1 = new BrightPlan_Chart.SummaryAnalysisMessages('1', '', 1, false);
		SummaryAnalysisMessages summaryAnalysisMessage2 = new BrightPlan_Chart.SummaryAnalysisMessages('2', '', 2, true);
		SummaryAnalysisMessages summaryAnalysisMessage3 = new BrightPlan_Chart.SummaryAnalysisMessages('3', '', 3, false);
		SummaryAnalysisMessages summaryAnalysisMessage4 = new BrightPlan_Chart.SummaryAnalysisMessages('4', '', 4, true);

		List<SummaryAnalysisMessages> assetAllocationSummaryList = new List<SummaryAnalysisMessages>{summaryAnalysisMessage1, summaryAnalysisMessage2, summaryAnalysisMessage3, summaryAnalysisMessage4};

		App_Comparator.sort(assetAllocationSummaryList, new BrightPlan_Chart.SummaryAnalysisMessagesCompare());
		System.assertEquals(assetAllocationSummaryList.get(0).getOrder(), 2);
		System.assertEquals(assetAllocationSummaryList.get(1).getOrder(), 4);
		System.assertEquals(assetAllocationSummaryList.get(2).getOrder(), 1);
		System.assertEquals(assetAllocationSummaryList.get(3).getOrder(), 3);

Apex DocumentLink Trigger to Share Documents to Community Contacts

Trigger to check if the custom object has the correct file shared to community user

public without sharing class Domain_Documents extends fflib_SObjectDomain {

	public Domain_Documents(List<Documents__c> records) {
		super(records);
	}

	public class Constructor implements fflib_SObjectDomain.IConstructable{

			return new Domain_Documents(sObjectList);
		}
	}

	public override void onAfterUpdate(Map<Id,SObject> existingRecords){
		List<ContentDocumentLink> contentDocumentLinksList = new List<ContentDocumentLink>();
		for (Documents__c documents : (List<Documents__c>) Records){
			if (documents.File_Id__c!=null){
				Documents__c existingDocument = (Documents__c)existingRecords.get(documents.Id);

					}
				 }
             }
		}

		if (!contentDocumentLinksList.isEmpty()){
			insert contentDocumentLinksList;

Apex save class when scheduled > ‘This schedulable class has jobs pending or in progress’

How do I develop in a class that is referenced in a scheduled job?You will see the following error when you try to save this class:

This schedulable class has jobs pending or in progress

There is the workaround, what I did is create a Job scheduler so basically 1 scheduled class from where I reference all my scheduled classes. We are not initializing the class by creating a object of the class by name:

global class App_Job_Scheduler implements Schedulable {

	global void execute(SchedulableContext sc) {
		System.Type closedAccountsScheduler = Type.forName('Job_Closed_Accounts');
		Schedulable closedAccountObject = (Schedulable)closedAccountsScheduler.newInstance();
		closedAccountObject.execute(sc);
       }
}

Scheduler class, now you can schedule this class and will not get the >This schedulable class has jobs pending or in progress error when you try to save any code to App_Service or Selector_Financial_Account

global class Job_Closed_Accounts implements System.Schedulable, Database.Batchable<SObject>, Database.Stateful, Database.AllowsCallouts {

	global Database.QueryLocator start(Database.BatchableContext BC) {
		return App_Selector_Financial_Account.newInstance().selectAccountAndRelatedObjectsToDelete();
	}

    global void execute(Database.BatchableContext BC, List<Financial_Account__c> financialAccountIdsToBeDeleted) {
		List<Financial_Account__c> financialAccountsToDelete = App_Selector_Financial_Account.newInstance().selectAccountAndRelatedObjectsToDelete(financialAccountIdsToBeDeleted);
		App_Service.instance.deleteRelatedAccountsRecords(financialAccountsToDelete);
	}

	global void finish(Database.BatchableContext BC) {}
}

Generating an Email-to-Case thread id using Apex

How to generate Email-to-Case thread id inside template:

Generate the thread Id

public static String getThreadId(String caseId){
public static String getThreadId(String caseId){
  return '[ ref:_'
     + UserInfo.getOrganizationId().left(5)
     + UserInfo.getOrganizationId().mid(11,4) + '._'
     + caseId.left(5)
     + caseId.mid(10,5) + ':ref ]';
}

Send customEmail and Add ThreadId

public void sendCustomEmail(User selectedUser, Contact selectedContact, String templateName, Map<String, String> customVariables){
    EmailTemplate emailTemplate = [select Id, Subject, HtmlValue, Body from EmailTemplate where DeveloperName=:templateName];

    if (selectedContact==null){
       selectedContact =  selectedUser.Contact;
    }

    String customSubject = emailTemplate.Subject;

    if (customVariables.containsKey('joinContactName')){
      customSubject = customSubject.replace('{!JointContactName}', customVariables.get('joinContactName'));
    }
    //Add ThreadId to the Subject
    if (customVariables.containsKey('ThreadId')) {
      customSubject = customSubject.replace('{!ThreadId}', customVariables.get('ThreadId'));
    }

    String htmlBody = emailTemplate.HtmlValue;
    htmlBody = htmlBody.replace('{!Contact.FirstName}',selectedContact.FirstName);
    htmlBody = htmlBody.replace('{!Contact.Email}', selectedContact.Email);
    if (customVariables.containsKey('Link')){
      htmlBody = htmlBody.replace('{!CustomUrl}', customVariables.get('Link'));
    } else if (customVariables.containsKey('link')){
      htmlBody = htmlBody.replace('{!CustomUrl}', customVariables.get('link'));
    } else if (customVariables.containsKey('joinContactName')){
      htmlBody = htmlBody.replace('{!JointContactName}', customVariables.get('joinContactName'));
    }

    //Add ThreadId to the htmlBody
    if (customVariables.containsKey('ThreadId')){
      htmlBody = htmlBody.replace('{!ThreadId}', customVariables.get('ThreadId'));
    }

    String plainBody = emailTemplate.Body;
    plainBody = plainBody.replace('{!Contact.FirstName}',selectedContact.FirstName);
    plainBody = plainBody.replace('{!Contact.Email}', selectedContact.Email);
    if (customVariables.containsKey('Link')){
      plainBody = plainBody.replace('{!CustomUrl}', customVariables.get('Link'));
    } else if (customVariables.containsKey('link')){
      plainBody = plainBody.replace('{!CustomUrl}', customVariables.get('link'));
    } else if (customVariables.containsKey('joinContactName')){
      plainBody = plainBody.replace('{!JointContactName}', customVariables.get('joinContactName'));
    }

    //Add the threadId to the plainBody
    if (customVariables.containsKey('ThreadId')){
      plainBody = plainBody.replace('{!ThreadId}', customVariables.get('ThreadId'));
    }

    Messaging.Singleemailmessage email = new Messaging.Singleemailmessage();
    List<OrgWideEmailAddress> orgWideEmailAddress = [Select Id, Address from OrgWideEmailAddress where DisplayName=:ORGWIDEEMAILADDRESSNAME];
    //Set ReplyTo as the Email-to-Case email address
    if (customVariables.containsKey('ThreadId')){
      List<EmailServicesAddress> emailServicesAddress = [SELECT Id,AuthorizedSenders,EmailDomainName,IsActive,LocalPart FROM EmailServicesAddress where IsActive=true and (LocalPart like '%service%' or LocalPart like '%support%')];
      if (!emailServicesAddress.isEmpty()){
        EmailServicesAddress emailToCase = emailServicesAddress.get(0);
        email.setReplyTo(emailToCase.LocalPart +'@'+ emailToCase.EmailDomainName);
        email.setSenderDisplayName('Client Support');
      } else {
        email.setReplyTo('customer-service@gmail.com');
        email.setSenderDisplayName('Client Support');
      }
    }

    email.setTargetObjectId(selectedContact.Id);
    email.setSaveAsActivity(true);

    email.setSubject(customSubject);

    email.setHtmlBody(htmlBody);
    email.setPlainTextBody(plainBody);

    if (customVariables.containsKey('WhatId')){
      email.setWhatId(customVariables.get('WhatId'));
    }

    Messaging.sendEmail(new Messaging.SingleEmailmessage[] {email});
}

Putting it all together

Map<String, String> mappingOfCaseFields = new Map<String, String>();
mappingOfCaseFields.put('ThreadId', App_Service.getThreadId(paymentCaseId));
App_Service.instance.sendCustomEmail(null, contact, 'App_Support_Template', mappingOfCaseFields);

Apex callout PATCH to Heroku Controller workaround

Setup a method to send Aync call to Heroku, add ‘?_HttpMethod=PATCH’ to the path to notify Heroku it’s a patch request

@future(callout=true)
	public static void callApiEndpointAsync(String apiEndpoint, String method, String aPayload){
		HttpRequest req = new HttpRequest();
		List<String> theArgs = new List<String>();
		HttpResponse res = new HttpResponse();
    try {
      if (apiEndpoint != null) {
        req.setTimeout(120000);
				if ('PATCH'.equals(method)){
					apiEndpoint += '?_HttpMethod=PATCH';
					req.setMethod('POST');
				} else {
					req.setMethod(method);
				}

        setAuthHeaderAsync(req);
        req.setEndpoint(herokuUrl + apiEndpoint);
				if (aPayload!=null)
					req.setBody(String.valueOf(aPayload));

				if (Test.isRunningTest() && (mock!=null)) {
					 mock.respond(req);
			 	} else {
					Integer retry = 0;

					while (retry < 2){
						Http http = new Http();
		        res =  http.send(req);
						if (res.getStatusCode() >= 200 && res.getStatusCode() < 300) {
							retry +=2;
						} else if (res.getStatusCode()==503 || res.getStatusCode()==400){
							retry +=1;
							res = http.send(req);
						} else {
							retry +=1;
							theArgs.add('Api');
							theArgs.add(req.getEndpoint());
							theArgs.add(res.getBody());
						}
					}
					throw new Rest_Exception(ResponseCodes_Mgr.getCode('HEROKU_REQUEST_CALLOUT_FAILED', null, theArgs));
				}

      } else {
        System.debug('Service apiEndpoint and payload must not be null');
        throw new Rest_Exception(ResponseCodes_Mgr.getCode('HEROKU_REQUEST_CALLOUT_FAILED'));
      }
    } catch (Exception ex) {
			theArgs.add('Api');
			theArgs.add(req.getEndpoint());
			theArgs.add(res.getBody());
			throw new Rest_Exception(ResponseCodes_Mgr.getCode('HEROKU_REQUEST_CALLOUT_FAILED', ex, theArgs));
			
    }
}

Spring controller checks the RequestParam _HttpMethod to see if it’s a POST or PATCH request

@RequestMapping(value = "/customer", method = RequestMethod.POST, produces = "application/json")
@ResponseBody
@ApiOperation(value = "Creates new payment customer")
@ApiResponses(value = {@ApiResponse(code = 200, message = "Creates new payment customer")})
public String createCustomer(@RequestBody PaymentCustomerWrapper paymentCustomerWrapper, @RequestParam(value="_HttpMethod", defaultValue="POST")  String httpMethod)
        throws IOException, URISyntaxException {
     if (httpMethod!=null && "PATCH".equals(httpMethod)){
         itsLogger.debug("update payment customer {}", paymentCustomerWrapper.toString());
         return paymentService.updatePaymentCustomer(paymentCustomerWrapper).toJson();
    } else {
         itsLogger.debug("create payment customer {}", paymentCustomerWrapper.toString());
         return paymentService.createChargeBeeCustomer(paymentCustomerWrapper).toJson();
    }
}

Heroku deploy local jar to Maven Dependencies

Sometime a jar is not available via Maven Central Repository and you need to load a jar from your local filesystem. Copy the jar file to a lib directory in your project.

Execute the following command via command line

mvn deploy:deploy-file -Durl=file:salesforce/lib/ 
-Dfile=salesforce/lib/emp-connector-0.0.1-SNAPSHOT-phat.jar 
-DgroupId=com.salesforce.conduit 
-Dpackaging=jar 
-Dversion=0.0.1-SNAPSHOT 
-DartifactId=emp-connector

Add the following to maven pom.xml

 <repositories>
    <repository>
        <id>project.local</id>
        <name>project</name>
        <url>file:${project.basedir}/lib</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </repository>
 </repositories>
 <dependencies>
    <dependency>
        <groupId>com.salesforce.conduit</groupId>
        <artifactId>emp-connector</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </dependency>

Apex Return Diff fields between records

Sometimes you want to determine what has changed between an existing record in the database and an update to the record. The diffRecord method will return all the fields that changed for a specific record.

Compare the difference between to records and return changed fields

public SObject diffRecord(SObject updatedRecord, SObject currentRecord, String sObjectName){
  SObjectType objToken = Schema.getGlobalDescribe().get(sObjectName);
  DescribeSObjectResult objDef = objToken.getDescribe();
  Map<String, SObjectField> fields = objDef.fields.getMap();
  Type classType = Type.forName(sObjectName);
  SObject diffRecord = (SObject)JSON.deserialize('{}', classType);
  for (String field : fields.keySet()){
    if (!fieldsToExclude.contains(fields.get(field).getDescribe().getName()) && (fields.get(field).getDescribe().isUpdateable() || fields.get(field).getDescribe().isCreateable())){
        if (updatedRecord.get(field)!=currentRecord.get(field))
        	diffRecord.put(field, updatedRecord.get(field));
    }
  }
  return diffRecord;
}

Test that only changed fields are returned

@isTest static void testDiffRecords(){
  String currentRecordJSON = '{"Id":"a0L63000000qc43EAA","Account_Type__c":"Managed","Amount__c":50.00,"Category__c":"Deposit","Description__c":"Deposit","End_Date__c":"2020-03-31T15:06:57.000+0000","Frequency__c":"Monthly"}';
  String updatedRecordJSON = '{"Amount__c":50.0,"Id":"a0L63000000qc43EAA","Frequency__c":"Annually"}';
  Type classType = Type.forName('Account');
  SObject currentRecord = (SObject)JSON.deserialize(currentRecordJSON, classType);
  SObject updatedRecord = (SObject)JSON.deserialize(updatedRecordJSON, classType);
  Test.startTest();
    SObject diffRecord = App_Service.instance.diffRecord(updatedRecord, currentRecord, 'Account');
    System.assertEquals(diffRecord.get('Amount__c'), null);
    System.assertEquals(diffRecord.get('Frequency__c'), 'Annually');
    System.assertEquals(diffRecord.get('Account_Type__c'), null);
    System.assertEquals(diffRecord.get('Category__c'), null);
  Test.stopTest();
}

Apex Compare two Records and Merge updated fields

When you have two record, one being the existing queried record and the other the updated record. To merge the original with the updated field without committing the changes you can iterate the current record’s fields and check which of the fields changed. Update the changed fields to the new updated fields value. Now we have an merged record. Here is how I went about doing it.

Original SObject record

{"Account_Type__c":"Managed","Amount__c":50.00,"Category__c":"Deposit",
"Description__c":"Deposit","End_Date__c":"2020-03-31T15:06:57.000+0000",
"Frequency__c":"Monthly"}

Update SObject record

{"Amount__c":500.0,"Id":"a0L63000000qc43EAA","Frequency__c":"Annually"}

Merge two records with changes

private static Set<String> fieldsToExclude = new Set<String>{'OwnerId','OtherGeocodeAccuracy','MailingGeocodeAccuracy','BillingGeocodeAccuracy','ShippingGeocodeAccuracy'};
public SObject mergeRecords(SObject updatedRecord, SObject currentRecord, String sObjectName){
  SObjectType objToken = Schema.getGlobalDescribe().get(sObjectName);
  DescribeSObjectResult objDef = objToken.getDescribe();
  Map<String, SObjectField> fields = objDef.fields.getMap();
  Type classType = Type.forName(sObjectName);
  SObject mergedRecord = (SObject)JSON.deserialize('{}', classType);
  for (String field : fields.keySet()){
    if (!fieldsToExclude.contains(fields.get(field).getDescribe().getName()) && (fields.get(field).getDescribe().isUpdateable() || fields.get(field).getDescribe().isCreateable())){
        if (updatedRecord.get(field)!=null){
        	mergedRecord.put(field, updatedRecord.get(field));
    	} else if (currentRecord.get(field)!=null){
        	mergedRecord.put(field, currentRecord.get(field));
    	}
    }
  }
  return mergedRecord;
}

Test that fields were merged correctly

@isTest static void testMergeRecords(){
  String currentRecordJSON = '{"Id":"a0L63000000qc43EAA","Account_Type__c":"Managed","Amount__c":50.00,"Category__c":"Deposit","Description__c":"Deposit","End_Date__c":"2020-03-31T15:06:57.000+0000","Frequency__c":"Monthly"}';
  String updatedRecordJSON = '{"Amount__c":500.0,"Id":"a0L63000000qc43EAA","Frequency__c":"Annually"}';
  Type classType = Type.forName('Account');
  SObject currentRecord = (SObject)JSON.deserialize(currentRecordJSON, classType);
  SObject updatedRecord = (SObject)JSON.deserialize(updatedRecordJSON, classType);
  Test.startTest();
    SObject mergedRecord = mergeRecords(updatedRecord, currentRecord, 'Account');
    System.assertEquals(mergedRecord.get('Amount__c'), 500.0);
    System.assertEquals(mergedRecord.get('Frequency__c'), 'Annually');
    System.assertEquals(mergedRecord.get('Account_Type__c'), 'Managed');
    System.assertEquals(mergedRecord.get('Category__c'), 'Deposit');
  Test.stopTest();
