ASP.NET MVC AspNet.Identity - How do I save the loggedin UserID to a created record?

Question

I'm building a CRUD that is accessible only to logged in users and i'm trying to add extra information (userid) to the crud records. How do I go about fetching the userId and saving it with the record?

Here is my controller

public ActionResult Create()
{
    return View();
}

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "CompanyName,Telephone")]Company company)
{
    try
    {
        if (ModelState.IsValid)
        {
            db.Companies.Add(company);
            db.SaveChanges();
            return RedirectToAction("Index");
        }
    }
    catch (DataException /* dex */)
    {

        ModelState.AddModelError("", "Unable to save changes.");
    }

    return View(company);
}

Here is my model

namespace ProjectX.Models
{
    public class Company
    {
        //public int Id { get; set; }
        public int CompanyID { get; set; }
        public string CompanyName { get; set; }
        public string Telephone { get; set; }

    }
}

Thank you for your help!

You can access it in different ways depending where you are in the code but since you are in the controller you should have an extension method like this User.Identity.GetUserId(); It will be string in this case but you can parse it, but be sure your table AspNetUsers has the id as int datatype. Assuming this is true you can say:

[HttpPost, Authorize]
[ValidateAntiForgeryToken]
public ActionResult Create([Bind(Include = "CompanyName,Telephone")]Company company)
{
    try
    {
        if (ModelState.IsValid)
        {
            company.Id = int.Parse(User.Identity.GetUserId());
            db.Companies.Add(company);
            db.SaveChanges();
            return RedirectToAction("Index");
        }
    }
    catch (DataException /* dex */)
    {
        ModelState.AddModelError("", "Unable to save changes.");
    }

    return View(company);
}

Do not forget to apply [Authorize] attribute.

In case you want to save more data from a user to a Company then you need to get the user from database and then extract user`s data needed from it and then save them in company object like below:

var user = UserManager.FindById(int.Parse(User.Identity.GetUserId()));
company.Username = user.Username;
//and so on...

Here you have more details for this:

Thanks a million Rajmond! I will definitely accept this answer! — papapi, Sep 04 '18 at 14:09
