User
should have Items
. Should I store the User's Id
in Item
? Can I extend the User
class with an List<Item>
navigation property?I'm using "Individual User Accounts" from the MVC template.
Tried these:
'Membership.GetUser()' is null.
This question is related to
c#
asp.net
asp.net-mvc
asp.net-mvc-5
asp.net-identity
Try something like:
var store = new UserStore<ApplicationUser>(new ApplicationDbContext());
var userManager = new UserManager<ApplicationUser>(store);
ApplicationUser user = userManager.FindByNameAsync(User.Identity.Name).Result;
Works with RTM.
if anyone else has this situation: i am creating an email verification to log in to my app so my users arent signed in yet, however i used the below to check for an email entered on the login which is a variation of @firecape solution
ApplicationUser user = HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>().FindByEmail(Email.Text);
you will also need the following:
using Microsoft.AspNet.Identity;
and
using Microsoft.AspNet.Identity.Owin;
If you want the ApplicationUser object in one line of code (if you have the latest ASP.NET Identity installed), try:
ApplicationUser user = System.Web.HttpContext.Current.GetOwinContext().GetUserManager<ApplicationUserManager>().FindById(System.Web.HttpContext.Current.User.Identity.GetUserId());
You'll need the following using statements:
using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;
Getting the Id is pretty straight forward and you've solved that.
Your second question though is a little more involved.
So, this is all prerelease stuff right now, but the common problem you're facing is where you're extending the user with new properties ( or an Items collection in you're question).
Out of the box you'll get a file called IdentityModel
under the Models folder (at the time of writing). In there you have a couple of classes; ApplicationUser
and ApplicationDbContext
. To add your collection of Items
you'll want to modify the ApplicationUser
class, just like you would if this were a normal class you were using with Entity Framework. In fact, if you take a quick look under the hood you'll find that all the identity related classes (User, Role etc...) are just POCOs now with the appropriate data annotations so they play nice with EF6.
Next, you'll need to make some changes to the AccountController
constructor so that it knows to use your DbContext.
public AccountController()
{
IdentityManager = new AuthenticationIdentityManager(
new IdentityStore(new ApplicationDbContext()));
}
Now getting the whole user object for your logged in user is a little esoteric to be honest.
var userWithItems = (ApplicationUser)await IdentityManager.Store.Users
.FindAsync(User.Identity.GetUserId(), CancellationToken.None);
That line will get the job done and you'll be able to access userWithItems.Items
like you want.

In .Net MVC5 core 2.2, I use HttpContext.User.Identity.Name . It worked for me.
I feel your pain, I'm trying to do the same thing. In my case I just want to clear the user.
I've created a base controller class that all my controllers inherit from. In it I override OnAuthentication
and set the filterContext.HttpContext.User to null
That's the best I've managed to far...
public abstract class ApplicationController : Controller
{
...
protected override void OnAuthentication(AuthenticationContext filterContext)
{
base.OnAuthentication(filterContext);
if ( ... )
{
// You may find that modifying the
// filterContext.HttpContext.User
// here works as desired.
// In my case I just set it to null
filterContext.HttpContext.User = null;
}
}
...
}
string userName="";
string userId = "";
int uid = 0;
if (HttpContext.Current != null && HttpContext.Current.User != null
&& HttpContext.Current.User.Identity.Name != null)
{
userName = HttpContext.Current.User.Identity.Name;
}
using (DevEntities context = new DevEntities())
{
uid = context.Users.Where(x => x.UserName == userName).Select(x=>x.Id).FirstOrDefault();
return uid;
}
return uid;
This is how I got an AspNetUser Id and displayed it on my home page
I placed the following code in my HomeController Index() method
ViewBag.userId = User.Identity.GetUserId();
In the view page just call
ViewBag.userId
Run the project and you will be able to see your userId
