在Apex或VisualForce中合并以下两个列表的最佳方法是什么?数据是相关的,但无法一起查询,因此我需要将两个列表组合在一起。
注意事项:
两个列表:additionalInfoQuestionMaps是父List,additionalInfoQuestionAvailableResponses是子列表。可以有1到多个孩子。
我需要在Question_Type_Info__c对象上加入列表。
基本上它是来自父列表的一组问题,然后我需要将可能的答案与诸如Yes和Nothat之类的问题关联在子列表中。这些结果将以表格形式显示在VF页面上。
public with sharing class mytest {
public List<Questions__c> additionalInfoQuestionMaps {get;set;}
public List<Available_Question_Answer_Options__c> additionalInfoQuestionAvailableResponses {get;set;}
public List<retrieveMergedQuestionList> retrieveMergedQuestionLists {get;set;}
public String buildId {get;set;}
public Build__c build {get;set;}
public mytest() {
buildId = 'a1DV00000001BBBBBB';
build = sharedfile.getBuild(buildId);
updateAdditionalInfoQuestionMaps();
updateAdditionalInfoFieldValueIds();
updateAdditionalInfoQuestionAvailableResponses();
}
public void updateAdditionalInfoQuestionMaps() {
additionalInfoQuestionMaps = new List<Questions__c>([SELECT Id, Name,
Associated_Product_Item__c,
Associated_Product__c,
Label__c,
(select Response__c from Responses_Object__r),
Question_Type_Info__c,
Required__c
FROM Questions__c
WHERE Associated_Product__c = :build.Associated_Product__c
ORDER BY Sort_Index__c, Label__c]);
}
public Set<Id> additionalInfoFieldValueIds = new Set<Id>();
public void updateAdditionalInfoFieldValueIds(){
for (Questions__c aimb : additionalInfoQuestionMaps) {
additionalInfoFieldValueIds.add(aimb.Question_Type_Info__c);
}
}
public void updateAdditionalInfoQuestionAvailableResponses() {
additionalInfoQuestionAvailableResponses = new List<Available_Question_Answer_Options__c>([select Id,
Field_Value__c, Question_Type_Info__c
from Available_Question_Answer_Options__c
where Question_Type_Info__c IN :additionalInfoFieldValueIds]);
}
}
答案 0 :(得分:0)
如果我理解你的问题,我认为你应该参加一个包装课
看一下我之前在LaceySnr提供解决方案时发布的类似问题

希望这有帮助。
