初始化RoleManager在ASP.NET中的身份与自定义角色 [英] Initializing RoleManager in ASP.NET Identity with Custom Roles

问题描述

我改变了从字符串用户数据库中的主键使用教程为int <一个href=\"http://www.asp.net/identity/overview/extensibility/change-primary-key-for-users-in-aspnet-identity\">here,但我有困难初始化角色管理器。它曾经使用初始化

I changed the primary key for the user database from string to int using the tutorial here, but I'm having difficulty initializing the Role Manager. It used to be initialized using

var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(context));

我如何使用新的数据创建角色管理器？

How can I create the role manager using the new data?

更新：我使用MVC 5和6 EF

Update: I'm using MVC 5 and EF 6.

推荐答案

您 ApplicationRoleManager 可能看起来像这样。因为你必须从你的customRole类，而不是继承 IdentityRole 。

Your ApplicationRoleManager may look like this. because you have to inherit from your customRole class instead of IdentityRole.

public class ApplicationRoleManager : RoleManager<CustomRole, int>
{
    public ApplicationRoleManager(IRoleStore<CustomRole, int> roleStore)
        : base(roleStore)
    {
    }

    public static ApplicationRoleManager Create(IdentityFactoryOptions<ApplicationRoleManager> options, IOwinContext context)
    {
        return new ApplicationRoleManager(new RoleStore<CustomRole, int, CustomUserRole>(context.Get<ApplicationDbContext>()));
    }
}

然后，添加以下code到Startup.Auth.cs类，如果目前不存在。

Then add following code to Startup.Auth.cs class if not currently exists.

app.CreatePerOwinContext<ApplicationRoleManager>(ApplicationRoleManager.Create);

然后创建和管理角色。

Then you create and manage roles.

    var roleManager = HttpContext.GetOwinContext().Get<ApplicationRoleManager>();

    const string roleName = "Admin";

    //Create Role Admin if it does not exist
    var role = roleManager.FindByName(roleName);
    if (role == null)
    {
        role = new CustomRole();
        role.Id = 1; // this will be integer
        role.Name = roleName;

        var roleresult = roleManager.Create(role);
    }

希望这有助于。
