I am trying to save a multi select list on my user create in MVC 5, but the values are not saving. Values are saving only in edit. For some reason it's not working on create and it seems the issue is tied to the identity user. I have the same method implemented in a different controller for another entity and it's working fine.
I am trying to assign multiple health professionals to a user in the below code. I am not getting any errors or a break on save, it just doesn't save the values.
Can anyone please have a look at my code and give me a solution to this problem.
Here is my controller code relevant to creating a user:
public ActionResult Create()
{
PopulateDepartmentsDropDownList();
PopulateSuperiorsDropDownList();
// Show a list of available groups:
ViewBag.GroupsList = new SelectList(this.GroupManager.Groups, "Id", "Name");
var applicationUser = new ApplicationUser();
applicationUser.HealthProfessionals = new List<HealthProfessional>();
PopulateAssignedHealthProfessionals(applicationUser);
return View();
}
[HttpPost]
public async Task<ActionResult> Create([Bind(Exclude = "ProfilePicture")]RegisterViewModel userViewModel, ApplicationUser applicationUser, string[] selectedHealthProfessionals, params string[] selectedGroups)
{
if (selectedHealthProfessionals != null)
{
applicationUser.HealthProfessionals = new List<HealthProfessional>();
foreach (var healthProfessional in selectedHealthProfessionals)
{
var healthProfessionalToAdd = db.HealthProfessionals.Find(int.Parse(healthProfessional));
applicationUser.HealthProfessionals.Add(healthProfessionalToAdd);
}
}
if (ModelState.IsValid)
{
// To convert the user uploaded Photo as Byte Array before save to DB
byte[] imageData = null;
if (Request.Files.Count > 0)
{
HttpPostedFileBase poImgFile = Request.Files["UserPhoto"];
using (var binary = new BinaryReader(poImgFile.InputStream))
{
imageData = binary.ReadBytes(poImgFile.ContentLength);
}
}
var user = new ApplicationUser
{
UserName = userViewModel.Email,
FirstName = userViewModel.FirstName,
LastName = userViewModel.LastName,
Position = userViewModel.Position,
DepartmentID = userViewModel.DepartmentID,
SuperiorID = userViewModel.SuperiorID,
OfficeNumber = userViewModel.OfficeNumber,
CellNumber = userViewModel.CellNumber,
Email = userViewModel.Email
};
//Here we pass the byte array to user context to store in db
user.ProfilePicture = imageData;
var adminresult = await UserManager
.CreateAsync(user, userViewModel.Password);
//Add User to the selected Groups
if (adminresult.Succeeded)
{
if (selectedGroups != null)
{
selectedGroups = selectedGroups ?? new string[] { };
await this.GroupManager
.SetUserGroupsAsync(user.Id, selectedGroups);
}
return RedirectToAction("Users");
}
}
ViewBag.Groups = new SelectList(await RoleManager.Roles.ToListAsync(), "Id", "Name");
PopulateDepartmentsDropDownList(userViewModel.DepartmentID);
PopulateSuperiorsDropDownList(userViewModel.SuperiorID);
PopulateAssignedHealthProfessionals(applicationUser);
return View(applicationUser);
}
private void PopulateAssignedHealthProfessionals(ApplicationUser applicationUser)
{
var allHealthProfessionals = db.HealthProfessionals;
var userHealthProfessionals = new HashSet<int>(applicationUser.HealthProfessionals.Select(i => i.HealthProfessionalID));
var viewModel = new List<AssignedHealthProfessionals>();
foreach (var healthProfessional in allHealthProfessionals)
{
viewModel.Add(new AssignedHealthProfessionals
{
HealthProfessionalID = healthProfessional.HealthProfessionalID,
HealthProfessionalName = healthProfessional.Name,
HealthProfessionalSurname = healthProfessional.Surname,
Assigned = userHealthProfessionals.Contains(healthProfessional.HealthProfessionalID)
});
}
ViewBag.HealthProfessionals = viewModel;
}
Here is my create view:
