Accessing keys from a map in a SOQL Query

Biswajeet   October 5, 2016   No Comments on Accessing keys from a map in a SOQL Query

Using .KeySet() on a map, we will get a list of all the keys returned.

Map<Id, Master_Obj__c> masterMap = new Map<Id, Master_Obj__c>([SELECT Id, Name FROM Master_Obj__c]);
List<Detail_Obj__c> objDetailList = [Select Id, Name FROM Detail_Obj__c WHERE Master_Obj__c IN :masterMap.KeySet()]

Biswajeet   October 4, 2016   No Comments on How to cover pagereference method in test class

For Custom Controller


//Page reference to your VF Page
PageReference pageRef = Page.TestPage;
Test.setCurrentPage(pageRef);

//Pass necessary parameter
pageRef.getParameters().put('Id',id); 

//init controller 
CustomCtrl objCtrl = new CustomCtrl();

//Call pageRef mymethod
PageReference objPageRef = objCtrl.mymethod();

//Put system asserts
System.assertEquals (null,pageRef);

For Standard Controller

//First create record
Account acc = New Account();
acc.Name = 'Test Account';
INSERT acc;

//Page reference to your VF Page
PageReference pageRef = Page.TestPage;
Test.setCurrentPage(pageRef);

//Pass necessary parameter
pageRef.getParameters().put('Id',acc.id);   

//Pass your object to controller     
ApexPages.StandardController stc = new ApexPages.StandardController(acc);

//Call controller
CustomCtrl objCtrl = new CustomCtrl(stc);

//Call pageRef mymethod
PageReference objPageRef = objCtrl.mymethod();

//Put system asserts
System.assertEquals (null,pageRef);

List<CronTrigger> ctList = [SELECT Id, CreatedDate, CronExpression, CronJobDetailId, EndTime,

                            TimesTriggered FROM CronTrigger];

Custom Label in JavaScript File

Biswajeet   September 29, 2016   No Comments on Custom Label in JavaScript File

We use {!$Label.CustomLabelName}, when we call custom label in Visualforce page JavaScript function. But if we need to access custom labels in JavaScript file in static resource, then here is the way to get the custom label value.

Load the custom label in Visualforce Page before loading the static resource JavaScript file.

<script>
    window.$Label = window.$Label || {};
    $Label.MyCustomLable1 = '{!JSENCODE($Label.MyCustomLable1)}';
    $Label.MyCustomLable2 = '{!JSENCODE($Label.MyCustomLable2)}';
</script>

Use in JavaScript file.

console.log($Label.MyCustomLable1);
alert($Label.MyCustomLable1);
