对于身份2种子数据库 [英] Seed database for Identity 2
本文介绍了对于身份2种子数据库的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我碰到一个问题就来了与身份V2播种数据库。我从MVC5项目分离出来的IdentityModel到我的数据访问层,我安装EF迁移为好。所以我注释掉code这里面使用IdentityConfig.cs创建初始用户,并把code,看起来像这样我的种子数据库中
I came across a problem for seeding the database with Identity v2. I separated out the IdentityModel from the MVC5 project to my Data Access Layer where I setup EF Migrations as well. So I commented out the code which use inside "IdentityConfig.cs" to create initial user and put the code inside my seed database that looks like this
protected override void Seed(Repository.DataContext.IdentityDb context)
{
// var userManager = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();
// var roleManager = HttpContext.Current.GetOwinContext().Get<ApplicationRoleManager>();
var owinContext = new OwinContext();
var userManager = owinContext.GetUserManager<ApplicationUserManager>();
var roleManager = owinContext.Get<ApplicationRoleManager>();
const string name = "admin@admin.com";
const string password = "Admin@123456";
const string roleName = "Admin";
// //Create Role Admin if it does not exist
var role = roleManager.FindByName(roleName);
if (role == null)
{
role = new IdentityRole(roleName);
var roleresult = roleManager.Create(role);
}
var user = userManager.FindByName(name);
if (user == null)
{
user = new ApplicationUser { UserName = name, Email = name };
var result = userManager.Create(user, password);
result = userManager.SetLockoutEnabled(user.Id, false);
}
// // Add user admin to Role Admin if not already added
var rolesForUser = userManager.GetRoles(user.Id);
if (!rolesForUser.Contains(role.Name))
{
var result = userManager.AddToRole(user.Id, role.Name);
}
}
现在,当我运行命令更新的数据库,我得到了一个错误
Now when I am running command update-database, I got an error
Value cannot be null.
Parameter name: manager
它看起来像,我在code
It looks like, I am getting null in these two lines of code
var userManager = owinContext.GetUserManager<ApplicationUserManager>();
var roleManager = owinContext.Get<ApplicationRoleManager>();
任何建议吗?
推荐答案
这是为了避免使用OWIN上下文的方式:
This is the way to avoid using an OWIN context:
protected override void Seed(Repository.DataContext.IdentityDb context)
var roleStore = new RoleStore<IdentityRole>(context);
var roleManager = new RoleManager<IdentityRole>(roleStore);
var userStore = new UserStore<ApplicationUser>(context);
var userManager = new UserManager<ApplicationUser>(userStore);
var user = new ApplicationUser { UserName = "sallen" };
userManager.Create(user, "password");
roleManager.Create(new IdentityRole { Name = "admin" });
userManager.AddToRole(user.Id, "admin");
}
