I have a LINQ query in my controller that has a join which selects all records. I'm then passing the ReportCompletionStatus.AsEnumerable() model to my view. But I keep getting the fowlling exceptions..
The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery`1
but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1
I'm setting the model AsEnumerable() and my view is expecting @model IEnumerable so i'm still not sure why it's complaning...
Controller
var ReportCompletionStatus = from r in db.Report_Completion_Status
join rc in db.Report_Category
on r.Report_Category equals rc.ReportCategoryID
select new
{
r.Report_Num,
rc.ReportCategory,
r.Report_Sub_Category,
r.Report_Name,
r.Report_Owner,
r.Report_Link,
r.Report_Description,
r.Last_Published,
r.Previous_Published,
r.Published_By,
r.Previous_Published_By,
r.Last_Edited,
r.Edited_By
};
return View(ReportCompletionStatus.AsEnumerable());
Model
@model IEnumerable<WebReportingTool.Report_Completion_Status>
With your select new
, you project to an anonymous type, not to an IEnumerable<WebReportingTool.Report_Completion_Status>
You need to create a ViewModel class (as your projection has data from both Report_Completion_Status
and Report_Category
) and use it for projection and for your View's model.
class
public class SomeViewModel {
public int ReportNum {get;set;}
public string ReportCategory {get;set;
//etc.
}
projection
select new SomeViewModel
{
ReportNum = r.Report_Num,
ReportCategory = rc.ReportCategory,
//etc.
};
view
@model IEnumerable<SomeViewModel>
By the way, the AsEnumerable
is not necessary .
Here's how I got it to work.
Model
public class ReportCategoryListModel
{
public int Report_Num { get; set; }
public string ReportCategory { get; set; }
public string Report_Sub_Category { get; set; }
public string Report_Name { get; set; }
public string Report_Owner { get; set; }
public string Report_Link { get; set; }
public string Report_Description { get; set; }
public Nullable<System.DateTime> Last_Published { get; set; }
public Nullable<System.DateTime> Previous_Published { get; set; }
public Nullable<int> Published_By { get; set; }
public Nullable<int> Previous_Published_By { get; set; }
public Nullable<System.DateTime> Last_Edited { get; set; }
public Nullable<int> Edited_By { get; set; }
}
Controller
var ReportCompletionStatus = from r in db.Report_Completion_Status
join rc in db.Report_Category
on r.Report_Category equals rc.ReportCategoryID
select new ReportCategoryListModel
{
Report_Num = r.Report_Num,
ReportCategory = rc.ReportCategory,
Report_Sub_Category = r.Report_Sub_Category,
Report_Name = r.Report_Name,
Report_Owner = r.Report_Owner,
Report_Link = r.Report_Link,
Report_Description = r.Report_Description,
Last_Published = r.Last_Published,
Previous_Published= r.Previous_Published,
Published_By = r.Published_By,
Previous_Published_By = r.Previous_Published_By,
Last_Edited = r.Last_Edited,
Edited_By = r.Edited_By
};
return View(ReportCompletionStatus);
View
@model IEnumerable<WebReportingTool.Models.ReportCategoryListModel>
