Study Notes
Developer Fundamentals
- Use
Opportunity.sobjectType.getDescribe().getRecordTypeInfos()
to get a list of record types, and iterate through them untilisDefaultRecordTypeMapping()
is true. @AuraEnabled
annotation allows to create Apex classes that can be called from Lightning web componentspublic class CheckPaymentProcessor implements PaymentProcessor {
public void pay (Decimal amount);
}
- This code implements thePaymentProcessor
interface and creates a method namedpay
.@TestVisible
annotation makes a method accessible to the test class.- To create a currency input field that is viewable and editable only for users with the correct field level permissions use:
<lightning-input-field field-name="salary_c"></lightning-input-field>
.
Apex Fundamentals
- Ensure that the
Account
object has a master-detail relationship to theBranch
object. - Triggers fire multiple times during a transaction.
- Duplicate rules are executed once all DML operations commit to the database.
Process Automation
- Use
Test.getStandardPriceBookId()
to get the standard price book ID. - Use an aggregate function in a trigger on the Opportunity object to calculate a roll-up summary from a custom object that is not in a master-detail relationship.
User Interface
- Use a Standard Controller with a Custom List Controller extension in order to allow users to edit multiple records at once.
Testing
- Use the
BISTest (SeeAllData=true)
method allows access to the standard price book.
Salesforce Development Life Cycle
- Full Sandbox is ideal to create the same configuration as the production org for a team of developers working on their individual orgs.
- Ensure the
PrimaryId_c
custom field on theCandidate_c
custom object is marked as an External Id. - Trigger execution can affect by
before insert
,after insert
,before update
,after update
trigger events. DML
operations are going to be rolled back after debuging a flow is ended.
Lightning Web Components
fire()
method is used to fire an event in Aura application events.- When using the
Batchable
interface the Apex governor limits are reset for each iteration of theexecute()
method. - To troubleshoot performance issues when a custom page loads, use
System.debug()
. - Universal Containers can use Custom objects and fields, Roll-up summaries, and Relationships to build out the database layer for a Salesforce application.
- Callouts to external systems are not executed when debugging a flow.
- The developer should create a Screen-based flow to implement the functionality for a service agent to process damaged or stolen credit cards.
- To create an account, the developer uses
Account myAccount = new Account(Name = 'MyAccount');
to create an account object, theninsert myAccount;
inserts it into the database. - The loop using the
do
..while
statement executes 9 times. - The loop creates 9 new accounts and inserts them into the database with names like 'New Account 1', 'New Account 2', etc.
- There are 16 total accounts in the org, since the developer started with 5 and created 10 more.
- The final account created is named
New Account 10
. The loop code increment thex
variable up to 10 after each iteration. Therefore, the loop will execute 9 times (10 - 1 = 9), creating 9 new accounts.
