如何在visualforce页面上从父对象的相关列表中保存子对象记录

标签: controller salesforce visualforce apex

我想从visualforce页面上的Account对象的相关列表中动态保存商机记录。为此:

  • 我创建了一个VF页面,其中我使用了页面块表。
  • 当我点击添加行然后在表上创建一个新行但是当我保存机会时,AccountName字段在表(相关列表)上显示空白,并且该机会记录不会保存在特定帐户中。

我没有得到实际问题,因为当我进行系统调试时,账户和opplist没有在saveopp()上显示任何内容。我认为Accountid不会进入机会的查询领域。

如果你们有人帮助我解决这个问题,我将非常感激    问题。谢谢你的帮助:)

**VF Page:-**
<apex:page standardController="Account" extensions="taskDemo">
<apex:form >
<apex:pageBlock title="" id="pb1" >
<apex:pageBlockSection title="Assign" columns="2">
<apex:inputField value="{!Account.Name}"/>
<apex:inputField value="{!Account.AccountNumber}"/>
<apex:inputField value="{!Account.Phone}"/>
<apex:inputField value="{!Account.Website}"/>
<apex:commandButton value="updateRecord" action="{!save}"/>
</apex:pageBlockSection>
<apex:pageBlockTable value="{!oppList}" var="op">
        <apex:column headerValue="OpportunityName"> 
        <apex:inputField value="{!op.Name}">
        </apex:inputField>
        </apex:column>
        <apex:column headerValue="AccountName">
        <apex:inputField value="{!op.Account.Name}"></apex:inputField>
        </apex:column>
        <apex:column headerValue="Amount">
        <apex:inputField value="{!op.Amount}">

        </apex:inputField>
        </apex:column>
     </apex:pageBlockTable>
<apex:commandButton value="saveopp" action="{!saveopp}"/>
<apex:commandButton value="AddRow" action="{!addRow}" rerender="pb1"/>
</apex:pageBlock>
</apex:form>
</apex:page>

**Controller:-**
public class taskDemo {
 public ApexPages.StandardController controller;
 public List<Opportunity> oppList{get; set;}
 public Account a{get; set;}
 public String accId{get;set;}

public taskDemo(ApexPages.StandardController controller) {
    a = new Account();
    accId = controller.getId();
    System.debug('accid is::'+accId);
    oppList = [Select id,Name,Account.Name,Amount,StageName,CloseDate from 
                 Opportunity where AccountId =: accId];
}

public void addRow(){
    oppList.add(new Opportunity());
    Opportunity ts=new Opportunity();
    ts.AccountId = accId;
    System.debug('addrow::'+ ts.AccountId);
}
public PageReference saveopp(){
    if(a.Name != null){
        insert a;
        system.debug('a record is='+a);
        List<Opportunity> con = new List<Opportunity>();

        for(Opportunity os : oppList)
        {
            os.AccountId = accId;
            con.add(os);
            system.debug('os record is='+os);
        }
        if(con != null){
            upsert oppList;
            system.debug('opp record is='+oppList);
        }
    }
    return null;        

}}

答案 0 :(得分:0)

我想指出代码中需要的一些问题和更改:

  1. 您帐户的默认保存方法是重定向到标准页面。如果需要,我们需要再次重定向到visualforce页面。

  2. 构造函数定义不明确,因为如果帐户ID不存在,它会查询所有商机。

  3. 在addRow()中,您首先将记录添加到商机列表,然后初始化新的商机记录,这是不正确的。此外,我们无法在插入记录之前显示帐户名称。理想的解决方案是不在机会列表中再次显示帐户名称,因为我们在页面顶部有信息。我们可以在节省机会时将机会与帐户联系起来。

  4. 在saveopp()中,您必须插入帐户。

  5. 同样关闭日期是保存商机的必填字段。因此,我们需要从UI获取信息。

  6. 我已更新您的代码。如果您有任何疑问,请仔细阅读并告诉我。
