EF6 Fluent Сопоставление неправильных ключей для соединений

Question

Я пытаюсь получить EF6 Fluent Mappings для работы над моим текущим проектом. У меня есть следующее отображение заказа:

public class OrderMap : EntityTypeConfiguration<Order> 
{ 
    public OrderMap() 
    { 
     this.ToTable("OE_Orders"); 
     this.Property(o => o.BillToAddress.Address1).HasColumnName("BillToAddress1"); 
     this.Property(o => o.BillToAddress.Address2).HasColumnName("BillToAddress2"); 
     this.Property(o => o.BillToAddress.City).HasColumnName("BillToCity"); 
     this.Property(o => o.BillToAddress.State).HasColumnName("BillToState"); 
     this.Property(o => o.BillToAddress.Zip).HasColumnName("BillToZip"); 
     this.Property(o => o.ShipToAddress.Address1).HasColumnName("ShipToAddress1"); 
     this.Property(o => o.ShipToAddress.Address2).HasColumnName("ShipToAddress2"); 
     this.Property(o => o.ShipToAddress.City).HasColumnName("ShipToCity"); 
     this.Property(o => o.ShipToAddress.State).HasColumnName("ShipToState"); 
     this.Property(o => o.ShipToAddress.Zip).HasColumnName("ShipToZip"); 
     this.Property(o => o.Stop).HasColumnName("RouteStopNumber"); 

     this.HasKey(o => o.OrderNumber).HasMany(o => o.OrderLines).WithRequired(ol => ol.Order).HasForeignKey(ol => ol.OrderNumber); 
     this.HasKey(o => o.CustomerKey).HasRequired(o => o.Customer).WithRequiredDependent(); 
    } 
} 

По какой-то причине, это пытается отобразить CustomerKey к OrderLines вместо ORDERNUMBER. Понятия не имею почему. Я могу включить OrderLineMap, если вам это нужно. Сгенерированный SQL является:

    WHERE [Extent1].[OrderNumber] = @p__linq__0 
) AS [Project1] 
ORDER BY [Project1].[CustomerKey] ASC, [Project1].[CustomerKey1] ASC, [Project1].[C1] ASC 

Это линия в вопросе:

LEFT OUTER JOIN [dbo].[OE_OrderLines] AS [Extent3] ON [Extent1].[CustomerKey] = [Extent3].[OrderNumber] 

Не знаю, как это исправить. Я мог бы использовать некоторые советы или некоторые ресурсы, чтобы помочь мне понять, почему он неправильно отображает.

Дайте мне знать, как я могу обновить эту информацию, чтобы сделать ее более информативной.

Благодарим вас за ваше время!

Answer 1

Проблема заключается в этих двух линиях от конфигурации:

this.HasKey(o => o.OrderNumber).HasMany(o => o.OrderLines).WithRequired(ol => ol.Order).HasForeignKey(ol => ol.OrderNumber); 
this.HasKey(o => o.CustomerKey).HasRequired(o => o.Customer).WithRequiredDependent(); 

В терминах Fluent API EF, HasKey означает отображение первичных ключ, и вы указали его в два раза. Поскольку более поздний имеет приоритет (перезаписывает предыдущую настройку), в результате EF отображает столбец CustomerKey в виде PK таблицы Order.

Правильная конфигурация должна быть такой (я хотел бы предложить вам не смешивать свойства, ПК и объединение отображений):

this.HasKey(o => o.OrderNumber); 

this.HasMany(o => o.OrderLines) 
    .WithRequired(ol => ol.Order) 
    .HasForeignKey(ol => ol.OrderNumber); 

this.HasRequired(o => o.Customer) 
    .WithMany() 
    .HasForeignKey(o => o.CustomerKey);
