Connecting Unrelated Objects during Apex Trigger - triggers

Question

I am trying to create a trigger that does the following:
Once an Account has been created, create an unrelated record (called a "Portal Content" record) that bears the same name, assuming the default RecordTypeId
Take the ID of the newly created "Portal Content" record, and insert it into a lookup field on the originally created Account
Add the ID of the original Account, and enter it into a field of the newly created "Portal Content" record
Steps 1 and 2 were addressed in post Populate Lookup Field with Record Created From Trigger. The new problem is that when attempting Item 3, in the Trigger.isAfter code block, a.Portal_Content_Record__r returns null rather than with the Id value populated after insert p in the Trigger.isBefore block.
trigger newAccountCreated on Account (before insert, after insert) {
List<Account> alist = Trigger.New;
if(Trigger.isBefore){
for(Account a : alist) {
if (a.RecordTypeId == '012i0000001Iy1H') {
Portal_Content__c p = new Portal_Content__c(
Name=a.Name,
RecordTypeId='012i0000001J1zZ'
);
insert p;
a.Portal_Content_Record__c = p.Id;
system.debug('Made it to insert p. P = ' + p.Id +'. a.Portal_Content_Record__c = ' + a.Portal_Content_Record__c);
}
}
}
if (Trigger.isAfter) {
for(Account a : alist){
system.debug('a.Id = ' + a.Id + ', p = ' +a.Portal_Content_Record__r);
String p = a.Portal_Content_Record__c;
for(Portal_Content__c port : [SELECT ID FROM Portal_Content__c WHERE Id = :p]){
port.School_SFDC_ID__c = a.Id;
update port;
}
}
}
}
My question has two parts:
How do I assign a field on the newly inserted Portal_Content__c record with the ID of the Account that started the trigger?
Can this be done within this trigger, or is a secondary "helper" trigger needed?

Answer 1

I was able to figure out a way to answer this issue within the same Trigger. The Trigger.isAfter && Trigger.isInsert code block is what solved my problem.
trigger newAccountCreated on Account (before insert, after insert, after delete) {
List<Account> alist = Trigger.New;
List<Account> oldlist = Trigger.old;
if(Trigger.isBefore){
for(Account a : alist) {
if (a.RecordTypeId == '012i0000001Iy1H') {
Portal_Content__c p = new Portal_Content__c(
Name=a.Name,
RecordTypeId='012i0000001J1zZ'
);
insert p;
a.Portal_Content_Record__c = p.Id;
}
}
}
else if (Trigger.isAfter && Trigger.isDelete){
for(Account a : oldlist){
for(Portal_Content__c p : [SELECT ID FROM Portal_Content__c WHERE ID = :a.Portal_Content_Record__c]){
delete p;
}
}
}
if (Trigger.isAfter && Trigger.isInsert){
for(Account a : alist){
List<Portal_Content__c> plist = [SELECT ID FROM Portal_Content__c WHERE Id = :a.Portal_Content_Record__c];
for(Portal_Content__c p : plist){
p.School_SFDC_ID__c = a.Id;
update p;
}
}
}
}
This code block does a query for Portal_Contact__c records that match the Account record's Portal_Content_Record__c field value, which is assigned in the first code block. It then takes the Portal_Content__c records found, and assigns the original Account's Id to the record's School_SFDC_ID__c field value.
