如何将链接实体中的字段包括到全文实体索引中? [英] How to include field from a linked entity into Full-Text Entity Index?
问题描述
我已将客户位置添加到了全文实体索引中,但是无法弄清楚如何从位置中获取地址行1 成为全文的一部分-Text索引并显示在结果中。
I've added Customer Location to the Full-Text Entity Index, but cannot figure out how to get Address Line 1 from the Location to be part of the Full-Text Index and be displayed in the result.
推荐答案
要包括链接实体的字段(在一个(在数据输入屏幕上与顶级实体建立一对一的关系),则需要指定应使用哪个顶级实体字段以及PXSelectorAttribute来检索链接的实体。在顶级实体字段充当链接的实体之间的桥梁之后,您将指定辅助实体的字段,该字段应包含在全文索引中和/或显示在结果中。请记住,只有用PXSelectorAttribute或PXDimensionSelectorAttribute装饰的顶级实体字段才可以充当链接的实体之间的桥梁。
To includes fields of linked entities (those which are in one-to-one relationship with the top-level entity on a data entry screen), it's required to specify what top-level entity field should be used along with the PXSelectorAttribute to retrieve the linked entity. Right after the top-level entity field acting as a bridge between the linked entities, you will specify fields of the secondary entity, which should be included into the Full-Text Index and/or be displayed in the result. Keep in mind, that only top-level entity fields decorated with PXSelectorAttribute or PXDimensionSelectorAttribute have the ability to act as a bridge between the linked entities.
例如,包含字段从地址 DAC到客户位置全文实体索引中,您必须从位置中添加 DefAddressID 字段> DAC,然后从 Address DAC列出字段:
For example, to include fields from the Address DAC into the Customer Location Full-Text Entity Index, you must add the DefAddressID field from the Location DAC before listing fields from the Address 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; }
...
}
CustomerLocation >在以下代码段中找到的DAC可以用作自定义DAC的完美示例,该自定义DAC用于向全文实体索引添加客户位置:
The CustomerLocation DAC found in the following code snippet can serve as a perfect example of a custom DAC used to add Customer Location to the Full-Text Entity Index:
[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; }
}
遵守 DefAddressID 字段为了包含从地址 DAC到全文本实体索引的字段, CustomerLocation (客户位置)还利用附加到 BAccountID 的 CustomerAttribute >字段,以包含客户的自然应用程序型 AcctCD 键,而不是代理数据库级的 BAccountID 键。最后要提及的是 PXBreakInheritanceAttribute ,当在重建全文本实体索引屏幕上系统生成要使用的实体列表时,可防止初始化与基本DAC对应的PXCache对象通过全文实体索引。
Becides the DefAddressID field, which is used to include fields from the Address DAC to the Full-Text Entity Index, CustomerLocation also utilize CustomerAttribute attached to the BAccountID field to include Customer's natural application-wise AcctCD keys instead of the surrogate DB-level BAccountID keys. Last thing to mention is the PXBreakInheritanceAttribute required to prevent initialization of PXCache objects corresponding to base DACs when on Rebuild Full-Text Entity Index screen the system generates list of entities to be used by Full-Text Entity Index.
