web.config 中没有 roleManager 标签

Question

我正在使用带有 MVC4 的 Asp.Net。

这是我的Seed 方法：

    protected override void Seed(eManager.Web.Infrastructure.DepartmentDB context)
    {

        context.Departments.AddOrUpdate(d => d.Name,
            new Department() { Name = "Engineering" },
            new Department() { Name = "Sales"},
            new Department() { Name = "Shipping"},
            new Department() { Name = "Human Resources"});

        if (!Roles.RoleExists("Admin"))
        {
            Roles.CreateRole("Admin");
        }

        if (Membership.GetUser("Majid") == null)
        {
            Membership.CreateUser("Majid", "221230");
            Roles.AddUserToRole("Majid", "Admin");
        }
    }

这是我的 web.config：

但是没有 roleManager 标签，当我运行update-database 命令时，它会说

角色管理器功能尚未启用

谁能告诉我该怎么做？？

Answer 1

我想我有解决方案，我知道它已经晚了，但它肯定会帮助新学习者

出现此问题是因为您的解决方案没有正确的 DLL。 所以他们不需要任何代码粘贴，

1. 只需转到您的 Nuget 包和
2. 搜索MVCInstaller.MVC4包和
3. 安装它。
4. 确保再次检查您的 Web.Config 文件，因为它不会覆盖行，而是会添加新行。所以不要忘记删除旧的。

您已准备好使用您的命令！

Answer 2

如果不存在，为什么不添加它：

更新：

 <roleManager enabled="true">
      <providers>
        <clear/>
        <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/" />
        <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/" />
      </providers>
    </roleManager>
