On a user account page, I had to display specific information regarding the logged in user. Things like Name, Age etc. I designed a ViewModel called UserAccount which takes in a UserId as a parameter to its contructor and based on that value, the VM pulls information from the database for that specific user. Something like this:
public class UserAccount
{
public string Name { get; set;}
public int Age { get; set; }
public UserAccount(int userId)
{
User user = GetUserFromRepository(userId);
Name = user.Name;
Age = user.Age;
}
}
All information I needed was provided by the VM but when it came to attaching this VM to the View, I got stuck. I need to mention I’m quite new to MVC but then I managed to find the solution to this:
public ActionResult MyAccount()
{
if (!Helper.IsUserLoggedIn())
{
return Redirect(Helper.GetLoginPageWithRedirect());
}
else
{
var vm = new Core.ViewModel.UserAccount(Helper.GetUserIdFromSession());
return View(vm);
}
}
What this does is first check whether the user is actually logged in. If not, it redirects the user to the login page because they should not be able to access the account page without being signed in. Since you can actually pass in an object when returning a View, you can already initialise your object through constructor injection and then do “return View(YourAlreadyInitialisedObject”);” That saved me from writing extra lines of codes and it works brillantly.
