使用从触发器创建的记录来填充查找字段 [英] Populate Lookup Field with Record Created From Trigger

问题描述

我正在尝试创建一个执行以下操作的触发器:

I am trying to create a trigger that does the following:

1. 创建帐户后，请使用默认的RecordTypeId创建一个不相关的记录(称为门户内容"记录)，并使用相同的名称
2. 获取新创建的门户内容"记录的ID，并将其插入到最初创建的帐户"上的查找字段中.

我当前的代码成功完成了第1项，但是当我添加新代码完成第2项时，收到以下错误:

My current code does item 1 successfully, but when I added new code to complete item 2, I received the following error:

Line: 6, Column: 1
System.DmlException: Insert failed. First exception on row 0; first error: 
CANNOT_INSERT_UPDATE_ACTIVATE_ENTITY, newAccountCreated: execution of 
AfterInsert caused by: System.FinalException: Record is read-only 
Trigger.newAccountCreated: line 12, column 1: []

我当前的触发器如下:

trigger newAccountCreated on Account (after insert) {

    List<Account> alist = Trigger.New;

    for(Account a : alist) {

        if (a.RecordTypeId == '012i0000001Iy1H') {
//            system.debug(a.Name);
            Portal_Content__c p = new Portal_Content__c(Name=a.Name,School_SFDC_ID__c=a.Id);
            insert p;

            a.Portal_Content_Record__c = p.Id;
            update a;
        }
    }

}

我不明白为什么错误消息指出记录是只读的"或如何修改此错误.

I do not understand why the the error message states that the "Record is read only," or how to amend this error.

推荐答案

您不能在之后"触发器上更新同一记录，必须在之前触发器上完成；更改为:

You cannot update the same record on an 'after' trigger, it must be done on a before trigger; change to:

trigger newAccountCreated on Account (before insert) {
