asp.net mvc querying from different table to view - asp.net

Question

I need to query data from 2 table
public class UserProfile
{
public int UserId { get; set; }
public string UserName { get; set; }
public string Name { get; set; }
}
and
public class PrivateMessage
{
public int MessageId { get; set; }
public string Sender { get; set; }
public string Receiver { get; set; }
public string Subject { get; set; }
public string Message { get; set; }
private DateTime _date = DateTime.Now;
public DateTime sentDate { get { return _date; } set { _date = value; } }
}
and this what i tried on my controller
public ActionResult Index()
{
var x = User.Identity.Name;
var query = from p in db.PrivateMessages
join u in db.UserProfiles on p.Sender equals u.UserName
where p.Receiver == x
select new
{
u.UserName,
u.Name,
p.Receiver,
p.Subject,
p.Message,
p.sentDate
};
return View(query);
}
this is my view model
#model IEnumerable<SeedSimple.Models.PrivateMessage>
but i got this error
The model item passed into the dictionary is of type
'System.Data.Entity.Infrastructure.DbQuery1[<>f__AnonymousType95[System.String,System.String,System.String,System.String,System.DateTime]]',
but this dictionary requires a model item of type
'System.Collections.Generic.IEnumerable`1[SeedSimple.Models.PrivateMessage]'.
all i want is to get username and name from UserProfile table and receiver, subject, message and sentDate on PrivateMessage table

Answer 1

Well you're passing as a Model an anonymous type yet you have a strongly typed View.
You can either create a new ViewModel that contains all the fields you're using for your query and pass that, or you can pass all the properties in the ViewBag (not a pretty solution).
EDIT
Thought I'd give you an example.
Here is a ViewModel containing the data you need:
public class MessageViewModel
{
public string UserName { get; set; }
public string Name { get; set; }
public string Receiver { get; set; }
public string Subject { get; set; }
public string Message { get; set; }
public DateTime SentDate { get; set; }
}
In your view:
#model IEnumerable<SeedSimple.Models.MessageViewModel>
In your Controller:
public ActionResult Index()
{
var x = User.Identity.Name;
var result = from p in db.PrivateMessages
join u in db.UserProfiles on p.Sender equals u.UserName
where p.Receiver == x
select new MessageViewModel
{
UserName = u.UserName,
Name = u.Name,
Receiver = p.Receiver,
Subject = p.Subject,
Message = p.Message,
SentDate = p.sentDate
};
return View(result);
}
I hope this helps.
