Salesforce 如何在Apex触发器中从记录中拉入字段

我试图找出如何创建一个Apex触发器，根据机会类型触发不同的类。我在下面添加了我认为会起作用的内容，但它似乎不像我想象的那样拉动了领域。有人能告诉我如何从更新的记录中提取值吗？非常感谢您的帮助，因为我正在努力尽快修复此问题

trigger OrderRollupSummaryTrigger on Order_Location_Package__c (after insert, after update, after delete, after undelete) {

if (Order_Location_Package__c.Order_Sheet__c.Opportunity__c.Type = 'NEW' || Order_Location_Package__c.Order_Sheet__c.Opportunity__c.Type = 'Renewal') {
    if (trigger.isAfter && (trigger.isInsert || trigger.isUpdate || trigger.isUndelete)) {
        OrderLocationRollupSummary.rollupOrderPackages(trigger.new);
    }
    else if (trigger.isAfter && trigger.isDelete) {
        OrderLocationRollupSummary.rollupOrderPackages(trigger.old);
    }
}

else if (Order_Location_Package__c.Order_Sheet__c.Opportunity__c.Type != 'NEW' || Order_Location_Package__c.Order_Sheet__c.Opportunity__c.Type != 'Renewal') {
    if (trigger.isAfter && (trigger.isInsert || trigger.isUpdate || trigger.isUndelete)) {
        OrderLocationRollupSummaryOther.rollupOrderPackages(trigger.new);
    }
    else if (trigger.isAfter && trigger.isDelete) {
        OrderLocationRollupSummaryOther.rollupOrderPackages(trigger.old);
    }
}
}

谢谢

经过大量阅读，我找到了最好的方法。特别是使用公式字段（以避免触发器中的SOQL查询）

trigger OrderLocation RollupSummaryTrigger on Order\u Location\u Package\u\c（插入后、更新后、删除后、取消删除后）{
List OrderLocationPackageNewAllist=新列表（）；
List OrderLocationPackageTherList=新列表（）；
//根据条件检查并将记录添加到列表中
if（trigger.isAfter&（trigger.isInsert | | | trigger.isUpdate | | trigger.isUndelete））{
用于（订单、位置、包装、olp:trigger.new）
如果（olp.Opportunity_Type_uc=='NEW'| | olp.Opportunity_Type_uc=='Renewal'）
OrderLocationPackageNewAllist.add（olp）；
其他的
OrderLocationPackageTherList.add（olp）；
}
else if（trigger.isAfter&&trigger.isDelete）{
用于（订单、位置、包装、olp:trigger.old）
如果（olp.Opportunity_Type_uc=='NEW'| | olp.Opportunity_Type_uc=='Renewal'）
OrderLocationPackageNewAllist.add（olp）；
其他的
OrderLocationPackageTherList.add（olp）；
}
//将要处理的记录发送到RollupSummary类
if（orderLocationPackageNewAllist！=null&&！orderLocationPackageNewAllist.isEmpty（））
OrderLocationRollupSummary.rollupOrderPackages（OrderLocationPackageNewAllist）；
//将不符合条件的记录发送到其他RollupSummary类
if（orderLocationPackageTherList！=null&！orderLocationPackageTherList.isEmpty（））
OrderLocationRollupSummaryOther.rollupOrderPackages（orderLocationPackageOtherList）；
}

trigger OrderLocationRollupSummaryTrigger on Order_Location_Package__c (after insert, after update, after delete, after undelete) {
    
    List<Order_Location_Package__c> orderLocationPackageRenewalList = new list<Order_Location_Package__c>();
    List<Order_Location_Package__c> orderLocationPackageOtherList = new list<Order_Location_Package__c>();

    //Check and add the records to list based on condition
    if (trigger.isAfter && (trigger.isInsert || trigger.isUpdate || trigger.isUndelete)) {
        for(Order_Location_Package__c olp: trigger.new)
            if(olp.Opportunity_Type__c == 'NEW' || olp.Opportunity_Type__c == 'Renewal')
                orderLocationPackageRenewalList.add(olp);
            else
                orderLocationPackageOtherList.add(olp);
    }
    else if (trigger.isAfter && trigger.isDelete) {
        for(Order_Location_Package__c olp: trigger.old)
            if(olp.Opportunity_Type__c == 'NEW' || olp.Opportunity_Type__c == 'Renewal')
                orderLocationPackageRenewalList.add(olp);
            else
                orderLocationPackageOtherList.add(olp);     
    }


    //Send the records for processing to RollupSummary class
    if(orderLocationPackageRenewalList!=null && !orderLocationPackageRenewalList.isEmpty())
        OrderLocationRollupSummary.rollupOrderPackages(orderLocationPackageRenewalList);

    //Send the records not meeting the criteria to other RollupSummary class
    if(orderLocationPackageOtherList!=null && !orderLocationPackageOtherList.isEmpty())
        OrderLocationRollupSummaryOther.rollupOrderPackages(orderLocationPackageOtherList);

}
