Question

是否可以扩展页面图并修改数据库？

我有一个新页面，它将为现有客户添加位置，但希望这些位置仅显示在我的页面上，而不是显示在客户页面的位置选项卡中。因此，我将扩展Location表以识别从我的新页面创建的记录，并且必须将Customer Locations Datamember修改为以下

    public PXSelect<LocationExtAddress, Where<LocationExtAddress.locationBAccountID, Equal<Current<BAccount.bAccountID>,
And<LocationExtAddess.extendedField, IsNull>>>> Locations;

Answer 1

在 BusinessAccountGraphBase 类（这是CustomerMaint的基类）中声明的Locations数据视图没有声明委托：

public class BusinessAccountGraphBase<Base, Primary, WhereClause> : PXGraph<BusinessAccountGraphBase<Base, Primary, WhereClause>>
    where Base : BAccount, new()
    where Primary : class, IBqlTable, new()
    where WhereClause : class, IBqlWhere, new()
{
    ...
    public PXSelect<LocationExtAddress, Where<LocationExtAddress.locationBAccountID, Equal<Current<BAccount.bAccountID>>>> Locations;
    ...
}

因此，要在Customers屏幕上修改Locations数据视图，您只需为CustomerMaint BLC创建一个扩展，如下所示：

public class CustomerMaintExt : PXGraphExtension<CustomerMaint>
{
    public PXSelect<LocationExtAddress, 
        Where<LocationExtAddress.locationBAccountID, Equal<Current<BAccount.bAccountID>,
            And<LocationExtAddess.extendedField, IsNull>>>> Locations;
}
