MVC two joing table with link querry order by

I have this controller that return a grid but I would like to make some modification so my search result are order by location.

I have a table Master List that contain LastName, FirstName, and others fields and has one foreign key that is LocationID that is related to a Table phoneList Location and its primary key is ID.

My current controller work and return a result set:

var masterLists = db.MasterLists.Include(m => m.PhoneListLocation);

Open in new window

But when I made some modification bellow I get an error:

     var masterLists = from r in db.MasterLists.Include(m => m.PhoneListLocation)
                              orderby r.PhoneListLocation.ID
                              select r.PhoneListLocation;
                              




            return View(masterLists.ToList());

Open in new window

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[PhoneListTest.Models.PhoneListLocation]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[PhoneListTest.Models.MasterList]'.

Hi yguyon28;

The two queries are returning different data types. The first is returning a collection of MasterLists while the modified query that does not work returns collection of PhoneListLocation. While I do not work with Web applications I believe that the View is not expecting the PhoneListLocation data type.

What will be needed in the View?

Well this controller work

var masterLists = db.MasterLists.Include(m => m.PhoneListLocation);

but I'm trying to modified it so I can have an orderby from the location in the phoneListLocation...

What is the relationship between MasterLists and PhoneListLocation? Is it a One to One, One to Many?

I think your hangup may be here:

var masterLists = (from r in db.MasterLists.Include(m => m.PhoneListLocation)
		   orderby r.PhoneListLocation.ID
		   select r.PhoneListLocation);
// Not this - return View(masterLists.ToList());
// Use this instead:
return View(masterLists);

Open in new window

masterLists should already be a 'System.Collections.Generic.IEnumerable`1[PhoneListTest.Models.MasterList]'.

But I get this error when I run the code....

Server Error in '/' Application.

The model item passed into the dictionary is of type 'System.Data.Entity.Infrastructure.DbQuery`1[WebApplicationCodeFirstPhoneList.Models.PhoneListLocation]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[WebApplicationCodeFirstPhoneList.Models.MasterList]'.

the relation is one to many

Is your View method doing any sort of conversion? What does the view method take as a parameter?

No no conversion
