我正在尝试让EF6 Fluent Mappings为我当前的项目工作。我有以下订单映射：
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();
}
}
出于某种原因，这会尝试将CustomerKey映射到OrderLines而不是OrderNumber。我不知道为什么。如果您需要，我也可以包含OrderLineMap。生成的SQL是：
SELECT

[Project1].[OrderNumber] AS [OrderNumber],

这是有问题的一行：
LEFT OUTER JOIN [dbo].[OE_OrderLines] AS [Extent3] ON [Extent1].[CustomerKey] = [Extent3].[OrderNumber]
不确定如何修复它。我可以使用一些建议或一些资源来帮助我找出错误映射的原因。
让我知道如何更新此信息以使其更具信息性。
谢谢大家的时间！

问题在于配置的这两行：
// Print the submitted information:
if ( !empty($_POST['name']) && !empty($_POST['email']) && !empty($_POST['movie']) ) {
echo "Thank you for completing the survey. Here's what you said";
echo "<p>Your name is $_POST[name]";
echo "<p>Your e-mail address is $_POST[email]";
echo "<p>You recently watched $_POST[movie] and felt it was $_POST[rating]!";
// add another if here
if ($_POST['survey'] == 'yes') {
echo "<p>Thank you for agreeing to be contacted for future surveys";
} elseif ($_POST['survey'] == 'no') {
echo "<p>We respect your with not to be contacted for future surveys";
}
} else { // Missing form value.
echo '<p>Please go back and fill out all required fields.</p>';
}
在EF Fluent API术语中， 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();
表示映射主键，并且您已指定了两次。由于后者优先（覆盖先前的设置），因此EF将HasKey列映射为CustomerKey表的PK。
正确的配置应该是这样的（我建议你不要混合属性，PK和关联映射）：
