Reference model class in controller, so muliple data can be in one view - sql

Question

I am trying to get data from multiple SQL Server stored procedure to be accessible in 1 view so I can then run comparisons and create graphs/grids etc.
I got each section to work on their own, and I am now trying to get them to work together.
I have change my controller and put the field types into their own classes, and then created a "Ring of Rings" class, and put them all in.
namespace APP.Models
{
public class SP_RESULTS
{
public type Type { get; set; }
public status Status { get; set; }
public condition Condition { get; set; }
public rooms Rooms { get; set; }
}
public class type
{
[Key]
public decimal type_id { get; set; }
public string type_code { get; set; }
public string type_name { get; set; }
}
public class status
{
//status
public decimal status_id { get; set; }
public string status_code { get; set; }
public string status_name { get; set; }
public string rentable { get; set; }
}
public class condition
{
//condition
public decimal condition_id { get; set; }
public string condition_code { get; set; }
public string condition_name { get; set; }
public string rentable { get; set; }
public int colour_code { get; set; }
public int service_order { get; set; }
}
public class rooms
{
//rooms
public decimal room_id { get; set; }
public string room_no { get; set; }
public decimal type_id { get; set; }
public int floor { get; set; }
public decimal status_id { get; set; }
public decimal condition_id { get; set; }
}
}
I then amended each section of my controller that was running SQL Server stored procedures, to use the correct class name instead of the "ring of rings" name, IE:
var outputmodel4 = new List<rooms>();
var command4 = db.Database.Connection.CreateCommand();
command4.CommandText = "SELECT rooms.room_id , rooms.room_no , rooms.type_id , rooms.floor_no , rooms.status_id , rooms.condition_id FROM rooms";
using (var SPOutput4 = command4.ExecuteReader())
{
foreach (var row in SPOutput4)
{
outputmodel4.Add(new rooms()
{
room_id = (decimal)SPOutput4["room_id"],
room_no = (string)SPOutput4["room_no"],
type_id = (decimal)SPOutput4["type_id"],
floor_no = (int)SPOutput4["floor_no"],
status_id = (decimal)SPOutput4["status_id"],
condition_id = (decimal)SPOutput4["condition_id"],
});
}
db.Database.Connection.Close();
return View(outputmodel4);
}
...etc for other SQL stored procedures
..and the same with my view
#model IEnumerable<app.Models.SP_RESULTS >
<table class="table">
<tr>
<th>
#Html.DisplayNameFor(model => model.Rooms.room_id)
</th>
<th>
#Html.DisplayNameFor(model => model.Rooms.room_no)
</th>
<th></th>
</tr>
#foreach (var item in Model) {
<tr>
<td>
#Html.DisplayFor(modelItem => item.Rooms.room_id)
</td>
<td>
#Html.DisplayFor(modelItem => item.Rooms.room_no)
</td>
</tr>
}
</table>
…etc for the other models
Everything looks fine in VBS (no red swiggles), but when I access the view in the browser, I get an error:
Server Error in '/' Application.
The model item passed into the dictionary is of type 'System.Collections.Generic.List1[app.Models.rooms]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable1[app.Models.SP_RESULTS]'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidOperationException: The model item passed into the dictionary is of type 'System.Collections.Generic.List1[app.Models.rooms]', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable1[app.Models.SP_RESULTS]'.
If I go back to my "rings of rings" model, and change it to this :
public class SP_RESULTS
{
public IEnumerable<type> Type { get; set; }
public IEnumerable<status> Status { get; set; }
public IEnumerable<condition> Condition { get; set; }
public IEnumerable<rooms> Rooms { get; set; }
}
and change the following lines in in my controller:
var outputmodel4 = new List<rooms>();
outputmodel4.Add(new rooms()
to
var outputmodel4 = new List<SP_RESULTS>();
outputmodel4.Add(new SP_RESULTS()
VBS tells me that that
SP_RESULTS does not contain a definition for room_id
I've tried prefixing the definition with the class name, with no luck.
I've looked on SO, fourms.asp.net and google.. can cannot see a solution (there probably is, but I am unsure what solution I an looking for.... if that makes sense).
Would someone be able to tell me what I need to do to get all my model classes working in the same view ?
I apologise now, as I realize that this question has probably been asked several (million) times, but I cannot seem to fine out that jumps out says THIS is that way to do it.

Answer 1

For anyone else looking for an answer (and for future me), I got this work by putting the models like this :
namespace APP.Models
{
public class SP_RESULTS
{
public type Type { get; set; }
public status Status { get; set; }
public condition Condition { get; set; }
public rooms Rooms { get; set; }
public class type
{
[Key]
public decimal type_id { get; set; }
public string type_code { get; set; }
public string type_name { get; set; }
}
public class status
{
//status
public decimal status_id { get; set; }
public string status_code { get; set; }
public string status_name { get; set; }
public string rentable { get; set; }
}
public class condition
{
//condition
public decimal condition_id { get; set; }
public string condition_code { get; set; }
public string condition_name { get; set; }
public string rentable { get; set; }
public int colour_code { get; set; }
public int service_order { get; set; }
}
public class rooms
{
//rooms
public decimal room_id { get; set; }
public string room_no { get; set; }
public decimal type_id { get; set; }
public int floor { get; set; }
public decimal status_id { get; set; }
public decimal condition_id { get; set; }
}
}
}
Using VIEWDATA in the controller for each Store procedure:
var outputmodel3 = new List<SP_RESULTS.conditions>();
var command3 = db.Database.Connection.CreateCommand();
command3.CommandText = "dbo.pr_PROCEDUREONE";
command3.CommandType = System.Data.CommandType.StoredProcedure;
using (var SPOutput3 = command3.ExecuteReader())
{
foreach (var row in SPOutput3)
{
outputmodel3.Add(new SP_RESULTS.conditions()
{
condition_id = (decimal)SPOutput3["condition_id"],
condition_code = (string)SPOutput3["condition_code"],
condition_name = (string)SPOutput3["condition_name"],
});
}
ViewData["CONDITIONSOutput"] = outputmodel3;
}
var outputmodel4 = new List<SP_RESULTS.rooms>();
var command4 = db.Database.Connection.CreateCommand();
command4.CommandText = "SELECT rooms.room_id , etc FROM rooms";
using (var SPOutput4 = command4.ExecuteReader())
{
foreach (var row in SPOutput4)
{
outputmodel4.Add(new SP_RESULTS.rooms()
{
room_id = (decimal)SPOutput4["room_id"],
room_no = (string)SPOutput4["room_no"],
});
}
ViewData["ROOMSOutput"] = outputmodel4;
db.Database.Connection.Close();
return View();
}
..and then changing my view to read :-
table class="table">
<tr>
<th>
Condition ID
</th>
<th>
Condition code
</th>
<th>
Condition name
</th>
<th>
is it rentable?
</th>
<th>
Condition color code
</th>
<th>
Condition service order
</th>
<th></th>
</tr>
#foreach (var item in ViewData["CONDITIONSOutput"] as IEnumerable<Happ.Models.SP_RESULTS.conditions>)
{
<tr>
<td>
#item.condition_id
</td>
<td>
#item.condition_code
</td>
<td>
#item.condition_name
</td>
<td>
#item.rentable
</td>
<td>
#item.colour_code
</td>
<td>
#item.service_order
</td>
</tr>
}
</table>
<table class="table">
<tr>
<th>
Room ID
</th>
<th>
Room No
</th>
<th>
Rooms type_id
</th>
<th></th>
</tr>
#foreach (var item in ViewData["ROOMSOutput"] as IEnumerable<APP.Models.SP_RESULTS.rooms>)
{
<tr>
<td>
#item.room_id
</td>
<td>
#item.room_no
</td>
</tr>
}
</table>
