实体框架6.1.1索引的命名约定 [英] Entity Framework 6.1.1 Naming Convention for indexes

问题描述

我了解如何在代码中添加约定（使用迁移）项目。我已成功地设法执行表名，甚至将GUID Id字段更改为非集群。

但是我没有找到如何更改EF提供的默认索引名称

  [Index（IsUnique = true）] 
 public string Code {get;组; } 
 
 [索引] 
 public string说明{get;组; 
  

我有这两个要求。顶级索引应该命名为 UX_ [schema] _ [table] _Code ，第二个 IX_ [schema] _ [table] _Description

我还需要支持多个列索引，其中IsUnique仍将是UX，但列部分是所有列的骆驼案例组合（例如 UX_ [schema] _ [table] _CodeDescription 如果上面的两列在同一个索引中。

我假设我需要在IndexAttributeConvention之后添加它，以便所有当前的功能都可以工作并创建IndexAnnotations，但是如果在Attribute（或Fluent构造）中留下空白，我找不到Indexes接收其初始名称的位置。 p>

提前感谢

解决方案

您是否尝试过此注释：[Index （IndexName）]
或您的示例：

  [Index（IndexName，IsUnique = true） ] 
 public string Code {get; set;} 
  

I understand how to add conventions to the code first (with migrations) project. I have successfully managed to perform the table names and even changed GUID Id fields to non-clustered.

But I have not found how to change the default index name that EF supplies when no name is given.

[Index(IsUnique = true)]
public string Code { get; set; }

[Index]
public string Description { get; set; }

I have these two requirements. The top index should be named UX_[schema]_[table]_Code, the second IX_[schema]_[table]_Description

I also have the need to support multiple column indexes where IsUnique will still be UX but the column section is a Camel Case combination of all columns (e.g. UX_[schema]_[table]_CodeDescription if the two columns above where in the same index.

I'm assuming I would need to add this after the IndexAttributeConvention so that all the current functionality will work and create the IndexAnnotations. But I can't find where the Indexes are receiving their initial name if left blank in the Attribute (or Fluent construct).

Thanks in advance.

解决方案

Have you tried this annotation: [Index("IndexName")] or for your example:

[Index("IndexName", IsUnique = true)]
public string Code { get; set; }
