MVC 4 App - Get data from database - asp.net-mvc

Question

First of all I'd like to say, that I am super new to the MVC pattern, sorry if I am asking a stupid question.
My problem:
I am having trouble with the building of a profile page for my users. If a user goes to that page it's going to list information about them, like e-mail address, phone number, full name, etc..
Note:
I am using the "Basic" project template with SimpleMemberShipProvider hadling user actions.
The problem comes with the database querying, to get the necessary data about the user.
Here's my UserProfile table data:
CREATE TABLE [dbo].[UserProfile] (
[UserId] INT IDENTITY (1, 1) NOT NULL,
[UserName] NVARCHAR (MAX) NULL,
[FirstName] NVARCHAR (MAX) NULL,
[LastName] NVARCHAR (MAX) NULL,
[Age] INT NULL,
[Sex] NVARCHAR (MAX) NULL,
[SecretQuestion] NVARCHAR (MAX) NULL,
[SecretQuestionAnswer] NVARCHAR (MAX) NULL,
[MoneyIn] INT NULL,
[MoneyOut] INT NULL,
[TimesWon] INT NULL,
[Email] NVARCHAR (MAX) DEFAULT ('') NOT NULL,
[PhoneNumber] NVARCHAR (MAX) NULL,
[Address] NVARCHAR (MAX) NULL,
CONSTRAINT [PK_dbo.UserProfile] PRIMARY KEY CLUSTERED ([UserId] ASC)
);
My 'User' model:
[Table("UserProfile")]
public class User
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
[Column("UserName")]
public string UserName { get; set; }
[Column("Email")]
[Required]
public string Email { get; set; }
[Column("FirstName")]
public string FirstName { get; set; }
[Column("LastName")]
public string LastName { get; set; }
[Column("PhoneNumber")]
public string PhoneNumber { get; set; }
[Column("Address")]
public string Address { get; set; }
[Column("Age")]
[Required]
public int Age { get; set; }
[Column("Sex")]
public string Sex { get; set; }
[Column("SecretQuestion")]
[Required]
public string SecretQuestion { get; set; }
[Column("SecretQuestionAnswer")]
[Required]
public string SecretQuestionAnswer { get; set; }
[Column("MoneyIn")]
public int MoneyIn { get; set; }
[Column("MoneyOut")]
public int MoneyOut { get; set; }
[Column("TimesWon")]
public int TimesWon { get; set; }
}
Here's my DbContext class:
public DbSet<User> Users { get; set; }
My controller with the 'Profile' action:
[Authorize]
public ActionResult Profil()
{
var model = db.Users.ToList();
return View(model);
}
And finally some relevant parts of my view to display the data:
#model IEnumerable<OneMillion.Models.User>
#foreach (var item in Model)
{
#item.FirstName
}
The error I get when trying to access the page as a logged in user:
Server Error in '/' Application.
The 'MoneyIn' property on 'User' could not be set to a 'null' value. You must set this property to a non-null value of type 'Int32'.
Thanks!

Answer 1

try to set the properties to be a nullable type ->
[Column("MoneyIn")]
public int? MoneyIn { get; set; }
[Column("MoneyOut")]
public int? MoneyOut { get; set; }

Answer 2

Your model and database definitions don't match, you have nullable fields in the database definition (Age, MoneyIn, MoneyOut and TimesWon) but non-nullable fields in the model.
