c# - 在 ASP .NET MVC 应用程序中使用 UserManager 的种子方法期间没有创建用户

标签 c# .net entity-framework asp.net-mvc-5.1

当 Seed 方法运行时，记录/对象被添加到我的数据库中。

在我尝试将用户添加到我的应用程序之前(在 Seed 方法的底部)，每个对象都按应有的方式添加。没有人被添加。还有很多 SQL 抛出的异常张贴在底部。即使 Seed 方法为空，它们也会被抛出。

如何将用户添加到 Entity Framework 管理的数据库？我按照 Scott Allen 的教程创建了我的代码。

 protected override void Seed(WebApplication2.Models.ApplicationDbContext context) {

            System.Diagnostics.Debug.WriteLine("Seed started");//IT WORKS

            if (!context.Persons.Any()) {
                var persons = new List<Person> { 
             new Person{FirstName = "John", LastName = "Doe", CellNumber = "123-456-789", SecondaryPhoneNumber = "98873213", Address = "1street 2",BirthDate = DateTime.Now.Date, Pesel = "312312312", Notes = "Annoying"},
             new Person{FirstName = "Anna", LastName = "Doe", CellNumber = "113-456-789", SecondaryPhoneNumber = "98873213", Address = "1street 2",BirthDate = DateTime.Now.Date, Pesel = "548555672", Notes = "Less Annoying"}
            };

                persons.ForEach(person => context.Persons.AddOrUpdate(person));
                context.SaveChanges();
            }

            if (!context.Meetings.Any()) {
                var meetings = new List<Meeting>{
                new Meeting{PersonId = 1, Body = "Body of meeting", Date = DateTime.Now}
            };


                meetings.ForEach(meeting => context.Meetings.AddOrUpdate(meeting));
                context.SaveChanges();
            }
            if (!context.Statuses.Any()) {
                var statuses = new List<Status> {

                statuses.ForEach(status => context.Statuses.AddOrUpdate(status));
                context.SaveChanges();

            }
           //EVERYTHING TILL NOW WORKS
            //Users Seeding

            if (!context.Users.Any()) {
                System.Diagnostics.Debug.WriteLine("USER SEED");
                try {
                    var store = new UserStore<ApplicationUser>(context);
                    var manager = new UserManager<ApplicationUser>(store);
                    //why user is not created
                    var user1 = new ApplicationUser { UserName = "admin", Email = "informatyka4444@wp.pl" };
                    var user2 = new ApplicationUser { UserName = "emp", Email = "informatyka4444@wp.pl" };
                    manager.Create(user1, "admin");
                    manager.Create(user2, "emp");

                    context.SaveChanges();
                } catch (Exception e) { System.Diagnostics.Debug.WriteLine("THERE WAS AN EXCEPTION"); }
            }


        }

编辑:

我在添加用户的部分添加了一些打印件，我还发布了带有一些 SQL 异常的输出。

if (!context.Users.Any()) {
            System.Diagnostics.Debug.WriteLine("USER SEED");
            try {
                System.Diagnostics.Debug.WriteLine("1");
                var store = new UserStore<ApplicationUser>(context);
                var manager = new UserManager<ApplicationUser>(store);
                //why user is not created
                System.Diagnostics.Debug.WriteLine("2");
                var user1 = new ApplicationUser { UserName = "admin", Email = "informatyka4444@wp.pl" };
                var user2 = new ApplicationUser { UserName = "emp", Email = "informatyka4444@wp.pl" };
                System.Diagnostics.Debug.WriteLine("3");

            } catch (Exception e) { System.Diagnostics.Debug.WriteLine("THERE WAS AN EXCEPTION"); }

                            System.Diagnostics.Debug.WriteLine(error.ErrorMessage);
                        }
                    }

                }
            }


        }
    }

最佳答案

您必须从上下文中获取当前经理:

var manager = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>();

一定要为此包含命名空间:

using Microsoft.AspNet.Identity.Owin;

使用此管理器实例，您应该能够正确创建用户。
