No users have been created during Seed method using UserManager in ASP .NET MVC applications

问题


When the Seedmethod runs, records/objects are added to my database.

Every object is added as it should till I try add users to my application(at the bottom of Seed method). No one is added. Also there is lot of SQL exceptions thrown posted at the bottom. They are thrown even if Seed method is empty.

How to add users to Entity Framework managed database? I created my code following Scott Allen's tutorial.

 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> {
                new Status{Name = "OK"},
                new Status {Name = "NOT_OK"}
            };



                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"); }
            }


        }

EDIT:

I added some prints to the section where I add users also I posted output with some SQL exceptions.

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");
                manager.Create(user1, "admin");
                manager.Create(user2, "emp");
                System.Diagnostics.Debug.WriteLine("4");
                context.SaveChanges();
                System.Diagnostics.Debug.WriteLine("5");
            } catch (Exception e) { System.Diagnostics.Debug.WriteLine("THERE WAS AN EXCEPTION"); }
            System.Diagnostics.Debug.WriteLine("6");

Output:

You have to get the current manager from the context:

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

Be sure to inlude the namespace for this:

using Microsoft.AspNet.Identity.Owin;

Using this manager instance, you should be able to create a user correctly.
