权限管理----用户与模块关系

用户与模块关系功能，您可以写成跟用户与角色关系一样。不过下面实现方法会看到更多的权限控制。

介面如下截图：

 

数据表结构如下：

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[UsersModule](
    [UsersId] [int] NOT NULL,
    [ModuleId] [smallint] NOT NULL,
    [Purview] [int] NOT NULL
) ON [PRIMARY]

GO

ALTER TABLE [dbo].[UsersModule]  WITH CHECK ADD  CONSTRAINT [FK_UsersModule_Module] FOREIGN KEY([ModuleId])
REFERENCES [dbo].[Module] ([ModuleId])
ON UPDATE CASCADE
ON DELETE CASCADE
GO

ALTER TABLE [dbo].[UsersModule] CHECK CONSTRAINT [FK_UsersModule_Module]
GO

ALTER TABLE [dbo].[UsersModule]  WITH CHECK ADD  CONSTRAINT [FK_UsersModule_Users] FOREIGN KEY([UsersId])
REFERENCES [dbo].[Users] ([UsersId])
ON UPDATE CASCADE
ON DELETE CASCADE
GO

ALTER TABLE [dbo].[UsersModule] CHECK CONSTRAINT [FK_UsersModule_Users]
GO

  

接下来，我们得写分配权限的存储过程：

SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE PROCEDURE [dbo].[usp_UsersModule_AssignModuleAction]
(
    @UsersId int,
    @ModuleId smallint,    
    @Browsing bit,
    @Searching bit,
    @Creating bit,
    @Editing bit,
    @Updating bit,
    @Deleting bit,
    @Erasing bit,
    @Submiting bit,
    @Auditing bit,
    @Reporting bit,
    @Receiving bit,
    @Delivering bit    
)
AS
BEGIN TRANSACTION
    DECLARE @Purview int =0    
    
    IF @Browsing = 1
        SET @Purview = @Purview + 1
    IF @Searching = 1
        SET @Purview = @Purview + 2
    IF @Creating = 1  
        SET @Purview = @Purview + 4
     IF @Editing = 1 
        SET @Purview = @Purview + 8
     IF @Updating = 1 
        SET @Purview = @Purview + 16
     IF @Deleting= 1  
        SET @Purview = @Purview + 32
     IF @Erasing = 1
        SET @Purview = @Purview + 64
     IF @Submiting = 1
        SET @Purview = @Purview + 128
     IF @Auditing = 1
        SET @Purview = @Purview + 256
     IF @Reporting = 1
        SET @Purview = @Purview + 512         
     --如果有更多操作权限，可以此添加 
      IF @Purview >0 AND @Browsing =0
        SET @Purview = @Purview +1
    
IF (SELECT count(*)  FROM [UsersModule] WHERE [UsersId] = @UsersId AND [ModuleId] = @ModuleId )>0
    BEGIN        
        UPDATE [UsersModule] SET [Purview]=@Purview WHERE [UsersId] = @UsersId AND [ModuleId] = @ModuleId 
        IF @@ERROR<>0            
            ROLLBACK TRANSACTION    
    END
ELSE
    BEGIN
        INSERT INTO [UsersModule] ([UsersId] ,[ModuleId],[Purview] ) VALUES (@UsersId ,@ModuleId ,@Purview)
        IF @@ERROR<>0            
            ROLLBACK TRANSACTION    
    END
        COMMIT TRANSACTION

GO
