HI,
I am trying to return a model after a POST but I receive the following error:
Exception Details: System.InvalidOperationException: Operation is not valid due to the current state of the object.
Line 29: public UsersModel getUser(Int32 id) {
Line 30: return (
Line 31: from users in db.NUsers
Line 32: join userSettings in db.NUsersSettings
The code in the controller looks like this:
[AcceptVerbs( HttpVerbs.Post )]
public ActionResult Edit( NUsers user ) {
//Other code that doesn't affect the error :)
UsersModel userDetails = this.usersObj.getUser( user.UserID );
return View( userDetails );
}
The getUser method looks like this:
public UsersModel getUser(Int32 id) {
return (
from users in db.NUsers
join userSettings in db.NUsersSettings
on users.UserID equals userSettings.UserID
where users.UserID == id
select new UsersModel {
UserId = Convert.ToInt32( users.UserID ),
Email = Convert.ToString( users.Email ),
FirstName = Convert.ToString( users.FirstName ),
LastName = Convert.ToString( users.LastName ),
Language = Convert.ToString( userSettings.Language ),
Phone = Convert.ToString( users.Phone )
} ).First();
}
and finally the UsersModel if you think it is relevant:
public class UsersModel {
public int UserId;
public string Email;
public string FirstName;
public string LastName;
public string Language;
public string Phone;
public List<NLanguages> Languages;
public UsersModel() {
Models.Languages languagesObj = new Models.Languages();
Languages = languagesObj.getLanguages();
}
}
Any thoughts on what might be causing the error and what can I do to fix it?
Thx
