Asp.net mvc 迁移配置类中的My seeder锁定应用程序(Asp.net MVC)
我有以下迁移配置类:Asp.net mvc 迁移配置类中的My seeder锁定应用程序(Asp.net MVC),asp.net-mvc,seeding,Asp.net Mvc,Seeding,我有以下迁移配置类: namespace MVC_Authentication.Migrations { using Microsoft.AspNet.Identity.EntityFramework; using MVC_Authentication.Models; using System; using System.Data.Entity; using System.Data.Entity.Migrations; using System.L
namespace MVC_Authentication.Migrations
{
using Microsoft.AspNet.Identity.EntityFramework;
using MVC_Authentication.Models;
using System;
using System.Data.Entity;
using System.Data.Entity.Migrations;
using System.Linq;
using System.Threading.Tasks;
internal sealed class MigrationConfiguration : DbMigrationsConfiguration<ApplicationDbContext>
{
public MigrationConfiguration()
{
AutomaticMigrationsEnabled = true;
AutomaticMigrationDataLossAllowed = true;
ContextKey = "MVC_Authentication.Models.ApplicationDbContext";
}
protected override void Seed(ApplicationDbContext context)
{
// This method will be called after migrating to the latest version.
// You can use the DbSet<T>.AddOrUpdate() helper extension method
// to avoid creating duplicate seed data.
SeedDatabase(context).GetAwaiter().GetResult();
}
protected async Task SeedDatabase(ApplicationDbContext ctx)
{
var roleManager = new ApplicationRoleManager(new RoleStore<IdentityRole>(ctx));
if (await roleManager.FindByNameAsync("Administrator") == null)
await roleManager.CreateAsync(new IdentityRole("Administrator"));
if (await roleManager.FindByNameAsync("User") == null)
await roleManager.CreateAsync(new IdentityRole("User"));
ApplicationUserManager userManager = new ApplicationUserManager(new UserStore<ApplicationUser>(ctx));
var user_Admin = new ApplicationUser()
{
SecurityStamp = Guid.NewGuid().ToString(),
UserName = "Admin",
Email = "myEmail",
EmailConfirmed = true
};
if (await userManager.FindByNameAsync(user_Admin.UserName) == null)
{
await userManager.CreateAsync(user_Admin, "MyPassword");
await userManager.AddToRoleAsync(user_Admin.Id, "User");
await userManager.AddToRoleAsync(user_Admin.Id, "Administrator");
}
}
}
应用程序被锁定,我可以等待再等待。
也许我不应该在这里使用RoleManager和UserManager?这是播种角色和用户的唯一方法。
感谢您提供任何可能出错的提示。在RoleManager中尝试同步方法,而不是在ApplicationRoleManager中
var roleStore = new RoleStore<IdentityRole>(db);
var roleManager = new RoleManager<IdentityRole>(roleStore);
roleManager.FindName(...);
var-roleStore=新的roleStore(db);
var roleManager=新roleManager(roleStore);
roleManager.FindName(…);
如果同步版本的行为方式相同,您是否会尝试同步版本roleManager.FindByName()
intellisense没有提供同步版本FindByName(),请尝试roleManager而不是ApplicationRoleManager<代码>var roleStore=新roleStore(db);var roleManager=新roleManager(roleStore)代码>成功了。谢谢。哦,我不知道那会是解决办法,哈哈。我添加了答案,请标记为正确答案,谢谢!
var roleStore = new RoleStore<IdentityRole>(db);
var roleManager = new RoleManager<IdentityRole>(roleStore);
roleManager.FindName(...);
