ASP.NET MVC角色

Question

I imported an MVC 4 project that uses roles to control permissions to access different pages and blocks. I'm using Visual Studio Express 2013 for Web with Update 4.

However, I am getting the following error when I run the project (I have not modified anything yet). It uses the statement @if (Roles.IsUserInRole("[RoleName]") to show certain parts of the page.

System.Data.SqlClient.SqlException : {"Invalid objet name 'webpages_UsersInRoles'."}

I believe it could be because the database is empty (thus no roles have been defined). However, I tried to manually add roles and assign them to users using Server Explorer

I am able to login and register using the MVC template pages, but when I open any page that contains that statement I get the error and the app crashes.

Thanks

Answer 1

I found some additional documentation on the simple membership with MVC 4. There are indeed some tables that MVC needs in order to do this membership and one of them is webpages_UsersInRoles.

Have you tried Registering an account? It seems that should call the initialize method to create the tables in the database.

如果此应用程序旨在使用Windows身份验证，并且您正在IIS Express下运行，则可能就像将Windows身份验证标志设置为“ true”一样简单。

Invalid objet name error is related to sql server when table,store procedure is missing. Just check in Database if table is present [database].[schema].[tablename]
