Don't save the value in extra field in IdentityRole

Question

In IdentityFramework I add new field for my database the standart table Role(Description),

When I add the new role, I want to have the description for this role.

I make the cshtml file

@using (Html.BeginForm("CreateRole", "Role", FormMethod.Post))
{
@Html.AntiForgeryToken()
<div id="create-role-box">
    @Html.ValidationSummary(false)

    <div class="form-group">
        <label class="create-role-color">Название роли:</label>
        @Html.TextBoxFor(x => x.Name, new { @class = "input-form-create-role create-role-color" })
        @Html.ValidationMessageFor(x => x.Name)
    </div>

    <div class="form-group">
        <label class="create-role-color">Описание роли:</label>
        @Html.TextBoxFor(x => x.Description, new { @class = "input-form-create-role create-role-color" })
        @Html.ValidationMessageFor(x => x.Description)
    </div>

    <div class="form-group" style="margin: 22px 0px 0px 0px;">
        <button type="submit" class="button-create-role">Добавить</button>

        @Html.ActionLink("Отмена", "Index", null, new { @class = "button-cancel" })
    </div>
</div>

}

post query in controller

 public async Task<ActionResult> CreateRole([Required]string name, string description)
    {
        if (ModelState.IsValid)
        {
            IdentityResult result = await roleManager.CreateRoleAsync(name, description);

            if (result.Succeeded)
            {
                return RedirectToAction("Index");
            }
            else
            {
                AddErrorsFromResult(result);
            }
        }
        return View(name);
    }

the CreateRoleAsync(name, description); method i discribe in repository

 public async Task<IdentityResult> CreateRoleAsync(string name, string description)
    {
        IdentityResult result = await userRole.CreateAsync(new UserRole(name, description));
        return result;
    }

and my UserRole model is

public class UserRole : IdentityRole
{
    public UserRole(string name, string description) : base(name)
    {
        description = Description;
    }

    public string Description { get; set; }
}

and if it's need my context

public class IdentityUserContext : IdentityDbContext<UserModel>
{
    public IdentityUserContext() : base("UserIdentityDbContext")
    {

    }
    // creating method realize by ninject in Ninject.Web.Common.cs WebUI->App_Start
}

the problem is that the description doesn't save in database,,

it's null but the method take the value of the description, why id isn't save in database.

First rename your UserRole class to ApplicationRole as follows because UserRole is confusing. UserRole should be named for User and Role many-to-many join table.

public class ApplicationRole : IdentityRole
{
    public ApplicationRole(string name) : base(name){}

    public string Description { get; set; }
}

Now create a RoleViewModel as follows:

public class RoleViewModel
{
    public string Id { get; set; }
    [Required(AllowEmptyStrings = false)]
    [Display(Name = "RoleName")]
    public string Name { get; set; }
    public string Description { get; set; }
}

Then your Create view:

@model Domain.ViewModels.RoleViewModel

@using (Html.BeginForm())
{
    // Your input fields and submit button here
}

Now write your CreateRole Post method as follows:

[HttpPost]
public async Task<ActionResult> CreateRole(RoleViewModel roleViewModel)
{
    if (ModelState.IsValid)
    {
        var role = new ApplicationRole(roleViewModel.Name);
        role.Description = roleViewModel.Description; // <--- Here you have to assign the `Description` value

        var roleresult = await RoleManager.CreateAsync(role);
        if (!roleresult.Succeeded)
        {
            ModelState.AddModelError("", roleresult.Errors.First());
            return View();
        }
        return RedirectToAction("Index");
    }
    return View();
}

Now everything will work fine!

If you want to create role from your repository method then write your CreateRoleAsync repository method as follows:

public async Task<IdentityResult> CreateRoleAsync(ApplicationRole applicationRole)
{
    IdentityResult result = await userRole.CreateAsync(applicationRole);
    return result;
}

Then call it in controller method as follows:

[HttpPost]
public async Task<ActionResult> CreateRole(RoleViewModel roleViewModel)
{
    if (ModelState.IsValid)
    {
        var role = new ApplicationRole(roleViewModel.Name);
        role.Description = roleViewModel.Description; // <--- Here you have assign the Description value

        IdentityResult result = await roleManager.CreateRoleAsync(role); // <-- call your repository method here.

        if (!roleresult.Succeeded)
        {
            ModelState.AddModelError("", roleresult.Errors.First());
            return View();
        }
        return RedirectToAction("Index");
    }
    return View();
}
