自定义对象的 Salesforce Apex 触发器

Question

我有一个名为“FinanceCapture”的自定义对象，它有一个帐户查找字段和一个名为 Contract_Term 的字段。我正在尝试编写一个 Apex 触发器，使 Contract_Term 的值等于合同对象中的合同期限值。

起草了以下代码，但它不起作用，需要您的帮助。谢谢

trigger populate_record on FinanceCapture__c (before insert) {
    List<Contract> ContractList = new List<Contract>();


    Map<Id,FinanceCapture__c> fin = new Map<Id,FinanceCapture__c>(
        [SELECT Id, FinanceCapture__lookup_Account__c FROM FinanceCapture__c WHERE Id IN :Trigger.New]);

    for (FinanceCapture__c a : Trigger.new){

//in Contract object, if its account ID matches with the account ID in FinanceCapture object, make the Contract_Term__c same as ContractTerm value

        If (ContractList.AccountId == fin.get(a.TMS_lookup_Account__c)){
            a.Contract_Term__c = ContractList.ContractTerm
        }
    }
}

有几点，您的 contractList 对象似乎没有填充任何东西，它只是一个空列表，因此，'if' 语句条件 ContractList.AccountId == fin.get(a.TMS_lookup_Account__c) 永远不会发生工作，不仅因为它是一个空列表，而且因为您正在尝试访问也不会工作的合同列表的 accountId。另一件事是您在 FinanceCapture__c 上使用两个不同的字段作为您的帐户查找字段，第一个 FinanceCapture__lookup_Account__c 在 SOQL 查询中，第二个 TMS_lookup_Account__c 在检查时具有 FinanceCaptures accountId 的合同 accountid。您需要明确说明您正在尝试做什么，这似乎是...

获取合同记录列表，其中accountId包含在accountId[=30=列表中] 来自 FinanceCapture__c 条记录的 trigger.new 列表。

对于所有 FinanceCapture__c 记录，其中已找到给定帐户 ID 的合同，设置 contract_term__c字段到对应的Contract记录contractTerm字段

这是应该实现的触发器（我使用 FinanceCapture__lookup_Account__c 作为查找字段名称）

trigger populate_record on FinanceCapture__c (before insert) { Map<Id, FinanceCapture__c> accountIds = new Map<Id, FinanceCapture__c>(); for(FinanceCapture__c fin : trigger.new){ accountIds.put(fin.FinanceCapture__lookup_Account__c, fin); //Add financeCapture Record to map with its accountId as the key } //Create a list of contracts with Id's in the set of id keys from account -> financeCapture map List<Contract> contractList = [SELECT id, contractTerm, accountId FROM Contract WHERE accountId IN :accountIds.keyset()]; for(Contract contract : contractList){ //Get the FinanceCapture record using the contracts accountId and //Set the Contract term fields to be equal accountIds.get(contract.AccountId).contract_Term__c = contract.ContractTerm; } }
