Shruthi MN 88 Write a trigger and a handler class
HI Everyone,
Can you help me write a handler class and a trigger for the below senario:
When a Contact (Account is null) is created with rating(a custom field - text type), check for existing Account record with Site(ex: www.emaildomain.com) and rating (as contact's rating), and relate that orphan contact with that account record.
Can you help me write a handler class and a trigger for the below senario:
When a Contact (Account is null) is created with rating(a custom field - text type), check for existing Account record with Site(ex: www.emaildomain.com) and rating (as contact's rating), and relate that orphan contact with that account record.
Creating an apex handler class and relate to orphan contact to an existing Accountbbased on the site and Rating criteria.
Apex Handler class:
public class ContactTriggerHandler
{
public static void handleAfterInsert(List<Contact> newContacts)
{
Map<String, String> contactSiteRatingMap = new Map<String, String>();
For(Contact newContact: newContacts)
{
if(newContact.AccountId == null && newContact.site != null && newContact.Rating__C != null)
{
contactSiteRatingMap.put(newContact.Site, newContact.Rating__C);
}
}
if(!contactSiteRatingMap.isEmpty())
{
List<Account> matchingAccounts = [SELECT Id, Site, Rating__C from Account
WHERE Site IN : contactSiteRatingMap.keySet() AND
Rating__C IN : contactSiteRatingMap.values()];
List<Contact> contactsToUpdate = new List<Contact>();
for(Contact newContact : newContacts)
{
if(newContact.AccountId == null && newContact.site != null && newContact.Rating__c != null)
{
for(Account matchingAccount : matchingAccounts)
{
if(newContact.Site == matchingAccount.site && newContact.Rating__C == matching.Rating__C)
{
newContact.AccountId = matchingAccount.Id;
contactsToUpdate.add(newContact);
break;
}
}
}
}
if(!contactsToUpdate.isEmpty())
{
update contactsToUpdate;
}
}
}
}
Trigger:
This trigger will fire when a new Contact record is created.
trigger ContactTrigger on Contact(after insert)
{
ContactTriggerHandler.handleAfterInsert(Trigger.new)
}
I have written the below code. I have corrected the errors and now the code is not working. B elow is the trigger senario:.
I have two feilds on contact Site__c and Rating__c. ONce a contact gets created or updtaed the contact should search for the site name given in Site__C feild with account Site feild. Then the contact should get associated with the account and rating should be updated as per contact Rating__c feild.
Handler Class
public class ContactTriggerHandler {
public static void handleAfterInsert(List<Contact> newContacts) {
Map<String, String> contactSiteRatingMap = new Map<String, String>();
for (Contact newContact : newContacts) {
if(newContact.AccountId == null && newContact.Site__c != null && newContact.Rating__c != null){
contactSiteRatingMap.put(newContact.Site__c, newContact.Rating__c);
}
}
if (!contactSiteRatingMap.isEmpty()) {
List<Account> matchingAccounts = [SELECT Id, Site, Rating FROM Account
WHERE Site IN :contactSiteRatingMap.keySet() AND
Rating IN :contactSiteRatingMap.values()];
List<Contact> contactsToUpdate = new List<Contact>();
for (Contact newContact : newContacts) {
if (newContact.AccountId == null && newContact.Site__c != null && newContact.Rating__c != null) {
for (Account matchingAccount : matchingAccounts) {
if (newContact.Site__c == matchingAccount.Site && newContact.Rating__c == matchingAccount.Rating) {
newContact.AccountId = matchingAccount.Id;
contactsToUpdate.add(newContact);
}
}
}
}
if (!contactsToUpdate.isEmpty()) {
update contactsToUpdate;
}
}
}
}
Trigger
trigger ContactTrigger on Contact(after insert)
{
ContactTriggerHandler.handleAfterInsert(Trigger.new);
}
