EF CTP5代码首次TPC配置是否要求基类是抽象的。 [英] Does EF CTP5 code first TPC configuration require the base class to be abstract.

问题描述

对于CTP5代码，首先TPC才能正常工作，基类必须是抽象的吗？

 

例如，我有以下实体：

公共类责任中心 

{

public int ID {get;组; }

public string Name {get;组; }

}

 

公共类CostCenter：ResponsibilityCenter

{

public string Test   {get;组; }

}

 

我正在使用EF CTP5 Code First将这些实体配置为TPC。我无法在CostCenter配置中配置ResponsibilityCenter属性。 

 

例如，在下面的配置中，Name属性我执行配置时无法识别。 

属性（p => p.Name）.HasColumnName（" Description"）;

 

这是一个缺陷，还是需要为代码提取抽象的基类，首先是TPC允许配置基类属性？  

 

这是一个非常人为的例子。 

解决方案

我认为我的问题不够明确。我最终想要的是一个ResponsibilityCenter表和一个CostCenter表，其中CostCenter表包含ResponsibiltyCenter表的所有属性。

ResponsibilityCenter（ID，Name）

CostCenter（身份证，姓名，测试）

 

我相信以下内容：

TPH将生成一个包含两个实体的所有属性的表。 

TPT将生成一个ResponsibilityCenter表和一个CostCenter表，其中Cost Center表不具有来自ResponsibilityCenter表的非键属性（Name），表之间会有关系。

TPC会生成与TPT相同的表而没有表之间的关系。  ;

 

是否存在代码优先配置，可以在不更改实体类的情况下生成上面显示的两个表？

我想我真的很喜欢映射多个t的配置功能将层次结构中的ables转换为单个表。  

For CTP5 code first TPC to work properly, does the base class have to be abstract?

 

For example, I have the following entities:

public class ResponsibilityCenter 

{

public int ID { get; set; }

public string Name { get; set; }

}

 

public class CostCenter : ResponsibilityCenter

{

public string Test  { get; set; }

}

 

I am using EF CTP5 Code First to configure these entities as TPC. I am unable to configure the ResponsibilityCenter properties in the CostCenter configuration. 

 

For example, in the configuration below, the Name property is not recognized when I execute the configuration. 

Property(p => p.Name).HasColumnName("Description");

 

Is this a defect, or are the base class(es) required to be abstract for code first TPC to allow the base class properties to be configured?  

 

This is a very contrived example. 

解决方案

I don't think my question was clear enough. What I wanted to end up with was a ResponsibilityCenter table, and a CostCenter table where the CostCenter table includes all the properties of the ResponsibiltyCenter table.

ResponsibilityCenter (ID, Name)

CostCenter (ID, Name, Test)

 

I believe the following:

TPH would generate a single table with all the properties from both entities. 

TPT would generate a ResponsibilityCenter table and a CostCenter table where the Cost Center table would not have the non-key properties (Name) from the ResponsibilityCenter table, and there would be a relationship between the tables.

TPC would generate the same tables as TPT without the relationship between the tables. 

 

Is there a code-first configuration that would generate the two tables shown above without changing the entity classes?

I guess I would really like the configuration capability to map multiple tables in a hierarchy into a single table.
