Why IdentityRole id gets overriden by old name in View - entity-framework

Question

I'm trying to make an Edit Form for IdentityRole. When the page is loaded I normaly receive the model with Id something like this "09e43076-c333-4145-bccb-8bc7f9db470e", but when the view is created I see that #Html.HiddenFor(m => m.Id) gets an old name value instead of Id (see screenshots in the links below). Why is it happening? Thanks!
GET: Edit
[HttpGet]
public ActionResult Edit(string id)
{
_context = new ApplicationDbContext();
if (User.Identity.IsAuthenticated)
{
if (!isAdminUser())
{
return RedirectToAction("Login", "Account");
}
}
else
{
return RedirectToAction("Login", "Account");
}
var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));
var role = roleManager.FindByName(id);
return View(role);
}
View: Edit
#model Microsoft.AspNet.Identity.EntityFramework.IdentityRole
#{
ViewBag.Title = "Edit Role";
}
<h2>Edit User Role:</h2>
#section RolesCSS {
<link href="#Url.Content("~/Views/Role/style/style.css")" rel="stylesheet"/>
<div class="form-group">
#using (Html.BeginForm("Edit", "Role", FormMethod.Post, new { #class = "AddRoleForm" }))
{
#Html.HiddenFor(m => m.Id)
#Html.HiddenFor(m => m.Users)
<div class="Label">
<p>Edit New User Role Name:</p>
</div>
<div class="FormControl">
#Html.EditorFor(m => m.Name, new {htmlAttributes = new {#class = "form-control"}})
</div>
<div class="FormControl">
<input class="btn btn-default" type="submit" value="Edit Role"/>
</div>
}
</div>
}

Despite I've found a solution I'm still interested what was wrong with the first aproach.
I've found a workaround here (the content/explanation is in russian lang)
I created a class EditRoleModel as a temporary model, to avoid the issue I was having before,
public class EditRoleModel
{
public string Id { get; set; }
public string Name { get; set; }
}
that I pass as a model to View:
[HttpGet]
public ActionResult Edit(string id)
{
_context = new ApplicationDbContext();
if (User.Identity.IsAuthenticated)
{
if (!isAdminUser())
{
return RedirectToAction("Login", "Account");
}
}
else
{
return RedirectToAction("Login", "Account");
}
var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));
var role = roleManager.FindByName(id);
var model = new EditRoleModel() {Id = role.Id, Name = role.Name};
return View(model);
}
then I slightly change the View to recieve model of type EditRoleModel:
#model WebUI.Models.EditRoleModel
#{
ViewBag.Title = "Edit Role";
}
<h2>Edit User Role:</h2>
#section RolesCSS {
<link href="#Url.Content("~/Views/Role/style/style.css")" rel="stylesheet"/>
<div class="form-group">
#using (Html.BeginForm("Edit", "Role", FormMethod.Post, new { #class = "AddRoleForm" }))
{
<div>#Model.Id</div>
#Html.HiddenFor(m => m.Id)
<div class="Label">
<p>Edit New User Role Name:</p>
</div>
<div class="FormControl">
#Html.EditorFor(m => m.Name, new {htmlAttributes = new {#class = "form-control"}})
</div>
<div class="FormControl">
<input class="btn btn-default" type="submit" value="Edit Role"/>
</div>
}
</div>
}
and finaly this is the controller where I update the IdentityRole:
[HttpPost]
public ActionResult Edit(EditRoleModel model)
{
_context = new ApplicationDbContext();
if (User.Identity.IsAuthenticated)
{
if (!isAdminUser())
{
return RedirectToAction("Login", "Account");
}
}
else
{
return RedirectToAction("Login", "Account");
}
var roleManager = new RoleManager<IdentityRole>(new RoleStore<IdentityRole>(new ApplicationDbContext()));
IdentityRole role = roleManager.FindByName(model.Id);
if (role != null)
{
role.Name= model.Name;
IdentityResult result = roleManager.Update(role);
if (result.Succeeded)
{
return RedirectToAction("Index");
}
else
{
ModelState.AddModelError("", "Something went wrong!");
}
}
return View(model);
}
