SubSonic 3.0.0.2/3 | SimpleRepository

Question

我使用的是sql server2008，为了遵循最新的约定，我使用了新的模式，而不是现在看起来像这个newdbo.tablename的dbo.tablename。现在的问题是，SimpleRepository找不到newdbo.tablename，我假设它寻找的是dbo而不是newdbo，因为我的类被定义为：

这是我的表格:模式/所有者是"kiss“

CREATE TABLE [kiss].[Users](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [UserName] [nvarchar](20) NOT NULL,
    [UserPassword] [varbinary](128) NULL,
    [UserTypeID] [tinyint] NOT NULL,
    [ByPassAccessRestrictionsFlag] [bit] NOT NULL,
    [IsEnforcePasswordPolicy] [bit] NOT NULL,
    [PasswordExpirationDate] [datetime] NULL,
    [IsPwdChangeNextLogin] [bit] NOT NULL,
    [ShowLatestNewsFlag] [bit] NOT NULL,
    [SortRowNumber] [int] NOT NULL,
    [CreatedDate] [datetime] NOT NULL,
    [CreatedBy] [nvarchar](20) NOT NULL,
    [UpdatedDate] [datetime] NOT NULL,
    [UpdatedBy] [nvarchar](20) NOT NULL,
    [DeletedDate] [int] NULL,
    [eCrewID] [varchar](10) NULL,
    [EntityTypeID] [int] NOT NULL
)
GO

这是我的班级：

public class Users
{
    public Int32 ID { get; set; }
    public String UserName { get; set; }
    public Byte[] UserPassword { get; set; }
    public Byte UserTypeID { get; set; }
    public Boolean ByPassAccessRestrictionsFlag { get; set; }
    public Boolean IsEnforcePasswordPolicy { get; set; }
    public DateTime PasswordExpirationDate { get; set; }
    public Boolean IsPwdChangeNextLogin { get; set; }
    public Boolean ShowLatestNewsFlag { get; set; }
    public Int32 SortRowNumber { get; set; }
    public DateTime CreatedDate { get; set; }
    public String CreatedBy { get; set; }
    public DateTime UpdatedDate { get; set; }
    public String UpdatedBy { get; set; }
    public Int32 DeletedDate { get; set; }
    public String eCrewID { get; set; }
    public Int32 EntityTypeID { get; set; }
}

运行简单的代码：

   var repo = new SimpleRepository("kiss", SimpleRepositoryOptions.None);
   var users = repo.All<Users>();
   gvUsers.DataSource = users;
   gvUsers.DataBind();

产生一个错误：

Answer 1

您的登录的默认模式是什么？不幸的是，你的对象不可能知道你使用的是什么模式--这是app -> db记住，如果你有一个单独的模式，你应该使用一个默认使用该模式的登录。

Answer 2

有两种选择

首先，获取最新的源代码，并修改源码

1. 找到SchemaAttributes.cs，添加代码：

AttributeUsage(AttributeTargets.Class)公共类架构: SubSonicTableSchemaAttribute {公共架构(String SubSonicTableSchemaAttribute){ Schema = schema；}

公共字符串架构{ get；set；}

}

• 将SubSonicTableSchemaAttribute绑定到用户类

SubSonic.SqlGeneration.Schema.SubSonicTableSchema("kiss")公共类User{...}

• 查找Objects.cs文件，将代码添加到"public static ITable ToSchemaTable(this type，IDataProvider provider)“方法中

var模式= type.GetCustomAttributes()；foreach ( typeAttributes中的var typeAtt ){var typeAttributes= (SubSonicTableSchemaAttribute) typeAtt；result.SchemaName = schema.Schema；} }

第二，看看我的演示：Use subsonic 3.0 SimpleRepository to a existing database
