Question

我已将客户位置添加到全文实体索引中，但无法弄清楚如何从该位置获取地址行1 全文索引并显示在结果中。

Answer 1

要包含链接实体的字段（与数据输入屏幕上的与顶级实体一对一的关系的字段），需要指定哪个顶级实体字段应与PXSelectorAttribute一起使用以检索链接的实体。在作为链接实体之间桥梁的顶级实体字段之后，您将指定辅助实体的字段，这些字段应包含在全文索引中和/或显示在结果中。请记住，只有使用PXSelectorAttribute或PXDimensionSelectorAttribute修饰的顶级实体字段才能充当链接实体之间的桥梁。

例如，要将地址 DAC中的字段包含在客户位置全文实体索引中，您必须添加 DefAddressID 字段在列出地址 DAC中的字段之前，从位置 DAC：

public partial class Location : PX.Data.IBqlTable, IPaymentTypeDetailMaster, ILocation
{
    ...
    public abstract class defAddressID : IBqlField { }
    [PXDBInt()]
    [PXDBChildIdentity(typeof(Address.addressID))]
    [PXUIField(DisplayName = "Default Address", Visibility = PXUIVisibility.Invisible)]
    [PXSelector(typeof(Search<Address.addressID>), DirtyRead = true)]
    public virtual int? DefAddressID { get; set; }
    ...
}

以下代码段中的 CustomerLocation DAC可以作为用于将客户位置添加到全文实体索引的自定义DAC的完美示例：< / p>

[Serializable]
[PXCacheName("Customer Location")]
[PXBreakInheritance]
public partial class CustomerLocation : SelectedCustomerLocation
{
    public new abstract class bAccountID : IBqlField { }

    [Customer(typeof(Search<Customer.bAccountID,
        Where<Customer.type, Equal<BAccountType.customerType>,
            Or<Customer.type, Equal<BAccountType.prospectType>,
            Or<Customer.type, Equal<BAccountType.combinedType>>>>>),
        IsKey = true)]
    public override int? BAccountID { get; set; }

    public new abstract class locationCD : IBqlField { }

    public new abstract class descr : IBqlField { }

    public new abstract class defAddressID : IBqlField { }

    public new abstract class locType : IBqlField { }

    public new abstract class noteID : IBqlField { }

    [PXNote()]
    [PXSearchable(SM.SearchCategory.CR, "{1} {2}: {3}",
        new Type[] {
            typeof(CustomerLocation.bAccountID),
            typeof(Customer.acctCD),
            typeof(CustomerLocation.locationCD),
            typeof(CustomerLocation.descr) },
        new Type[] {
            typeof(CustomerLocation.bAccountID),
            typeof(Customer.acctCD),
            typeof(CustomerLocation.locationCD),
            typeof(CustomerLocation.descr),
            typeof(CustomerLocation.defAddressID),
            typeof(Address.addressLine1),
            typeof(Address.addressLine2),
            typeof(Address.city),
            typeof(Address.countryID) },
        Line1Format = "{0} {2}",
        Line1Fields = new Type[] {
            typeof(CustomerLocation.descr),
            typeof(CustomerLocation.defAddressID),
            typeof(Address.addressLine1) },
        Line2Format = "{1}",
        Line2Fields = new Type[] {
            typeof(CustomerLocation.defAddressID),
            typeof(Address.addressLine2) },
        WhereConstraint = 
            typeof(Where<CustomerLocation.locType, Equal<LocTypeList.customerLoc>,
                Or<CustomerLocation.locType, Equal<LocTypeList.combinedLoc>>>),
        MatchWithJoin = typeof(InnerJoin<Customer, 
            On<Customer.bAccountID, Equal<CustomerLocation.bAccountID>>>),
        SelectForFastIndexing = typeof(Select2<CustomerLocation, 
            InnerJoin<Customer, 
                On<CustomerLocation.bAccountID, Equal<Customer.bAccountID>>>>)
    )]
    public override Guid? NoteID { get; set; }
}

使用 DefAddressID 字段，该字段用于包含地址 DAC到全文实体索引的字段， CustomerLocation 也可以使用附加到 BAccountID 字段的 CustomerAttribute 包含客户的自然应用程序 AcctCD 键，而不是代理数据库级别 BAccountID 键。最后要提到的是 PXBreakInheritanceAttribute ，以防止在重建全文实体索引屏幕时初始化与基本DAC相对应的PXCache对象时系统生成要使用的实体列表通过全文实体索引。

如何将链接实体中的字段包含到全文实体索引中？
