如何从 visualforce 页面上父对象的相关列表中保存子对象记录

how can I save child object record from related list of parent object on visualforce page

我想从 visualforce 页面上的相关客户对象列表中动态保存商机记录。为此:

我没有遇到实际问题,因为当我进行系统调试时,Account 和 opplist 在 saveopp() 上没有显示任何内容。我认为 Accountid 不会进入业务机会的查找字段。

如果你们能帮我解决这个问题,我将不胜感激 问题。感谢您的帮助:)

我想指出您的代码中需要的几个问题和更改:

  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,它会查询所有机会。

  3. 在 addRow() 中,您先向机会列表添加一条记录,然后再初始化一条新的机会记录,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要在机会列表中再次显示客户名称,因为我们在页面顶部有信息。我们可以link在保存机会的时候把机会记入账户。

  4. 在saveopp()中,你必须upsert account。

  5. 此外,结束日期是保存商机的必填字段。因此我们需要从UI.

  6. 获取信息

我已经更新了你的代码。请仔细阅读,如果您有任何疑问,请告诉我。
