Updating Boolean field in MSSQL using LINQ and Entity Framework

Hello All,

I'm having a really frustrating time updating any fields in my database that are of type Boolean!!!

For instance I have:
ClassManagementEntities db = new ClassManagementEntities();
UserInformation user = new UserInformation();
user.Email = model.Email;
user.Roles = "Student";
user.Username = model.UserName;
user.UserInformationId = (Guid)memUser.ProviderUserKey;
user.IsApproved = true;
db.UserInformation.Add(user);
db.SaveChanges();

Open in new window


I then check in SQL Server Mangaement Studio and the value for IsApproved is set to 0. So frustrating. I've run out of ideas. I feel like this should be a simple task... does the type need to be bool vs Boolean?

No, it should be just as easy as you figured.  I have boolean columns (of tyep Boolean) in virtually every table, and it's a simple to update as any other, and just as you have.

Any chance you have triggers or code somewhere else in your model that might be resetting the value?
Is the property mapped properly?

no triggers I don't believe. I don't even know how to set tiggers :\

I'm using the entity framework (CTP 5). I define the UserInformation class as:
public class UserInformation
    {
        public string Username { get; set; }
        public Boolean IsApproved { get; set; }
        public string Email { get; set; }
        public Guid UserInformationId { get; set; }
        public string Roles { get; set; }
        public string SecretQuestion { get; set; }
        public string SecretAnswer { get; set; }
        public string ReturnUrl { get; set; }
        public int SemesterID { get; set; }
        public virtual Grade Grade { get; set; }
        public virtual Absent Absent { get; set; }
    }

I really appreciate your help!

instead of assigning value true, did you check with 1?
ClassManagementEntities db = new ClassManagementEntities();
UserInformation user = new UserInformation();
user.Email = model.Email;
user.Roles = "Student";
user.Username = model.UserName;
user.UserInformationId = (Guid)memUser.ProviderUserKey;
user.IsApproved = 1;
db.UserInformation.Add(user);
db.SaveChanges();

Weird... so now it's working properly... weird... Problem now is that the public string[] Roles { get; set;} is not being added to the database... so I have:
public class UserInformation
    {
        public string Username { get; set; }
        public Boolean IsApproved { get; set; }
        public string Email { get; set; }
        public Guid UserInformationId { get; set; }
        public string[] Roles { get; set; }
        public string SecretQuestion { get; set; }
        public string SecretAnswer { get; set; }
        public string ReturnUrl { get; set; }
        public int SemesterID { get; set; }
        public virtual Grade Grade { get; set; }
        public virtual Absent Absent { get; set; }
    }

Open in new window


I think cause it referencing Roles as Web.Security.Roles... which is unfortunate because I want to query users who have the role student from this table... do I need a public virtual Roles Roles get set or???

To Clarify in:

UserInformation user = new UserInformation();
                    user.Email = model.Email;
                    user.Roles = new string[] { "Student" };
                    user.Username = model.UserName;
                    user.UserInformationId = (Guid)memUser.ProviderUserKey;
                    user.IsApproved = true;

                    ProfileInformation profile = ProfileInformation.GetProfile(model.UserName);
                    profile.SemesterID = currentSemesterID;
                    user.SemesterID = Int32.Parse(currentSemesterID);
                    db.UserInformation.Add(user);
                    db.SaveChanges();

The line:
user.Roles = new string[] { "Student" };

Is not represented in my database.... as in it's not being save AND it's not even a column of the Userinformation Table...

I guess since I have the boolean part working I could create a field isStudent and set it to true if they're a student... but then I'll have to update another method when the user is set to faculty or admin isStudent is set to false... which is doable, but is it best practice... I don't think so... sorry just thinking out loud...
