I have a model which is storing mycustomer new request information.
In another history model i am storing all previous request of the customer.
In view i would like to take new order and also see his previous orders and suggest some food after seeing his previous order.
Here are my models...
public class CustomerFoodModel
{
public DateTime FoodRequestCreated { get; set; }
public string FoodRequestType { get; set; }
...
...
}
public class CustomerHistoryModel
{
public string Name { get; set; }
public DateTime FoodRequestCreated { get; set; }
public string FoodRequestType { get; set; }
...
...
}
Helper.cs file
public static CustomerFoodModel getCustomerDetails(int id) // id is loyalty card number
{
// get details from (cutomer) sql table
//store it in (CustomerFoodModel)
// check if it has previous orders
getCustomerHistoryDetails(id);
....
}
public static CustomerHistoryModel getCustomerHistoryDetails(int id)
{
// get deails from (history) sql table
// store it in (CustomerHistoryModel
}
In my controller, I am passing my (CustomerFoodModel) to the view.
public ActionResult EditCustomerRequest(int id, string name, string date)
{
CustomerFoodModel CRequest = Helper.getCustomerDetails(id);
...
return PartialView("EditCustomerRequest",CRequest);
}
How do I show the (CustomerHistoryModel) in the same view.? Is there possible to include (CustomerHistoryModel) in (CustomerFoodModel)?
Create a new class to wrap both of the model.
public class CustomerFoodModel
{
public CustomerFoodModel CustomerFood { get; set; }
public CustomerHistoryModel CustomerHistory { get; set; }
}
And on your controller
public ActionResult EditCustomerRequest(int id, string name, string date)
{
CustomerFoodModel CRequest = Helper.getCustomerDetails(id);
CustomerHistoryModel CHModel = Helper. getCustomerHistoryDetails(id);
return PartialView("EditCustomerRequest",new CustomerFoodModel(){
CustomerFood = CRequest,
CustomerHistory = CHModel
});
}
I think the best approach is to use a partial view inside the main view. The partial view can call back to another controller to get a new model and pass that model to the partial view. This keeps things better seperated.
Look at this post for a similar issue.
Using partial views in ASP.net MVC 4
Use wrapper class which contain both of class
public class CustomerViewModel
{
public CustomerFoodModel FoodModel { get; set; }
public CustomerHistoryModel HistoryModel { get; set; }
}
You have a few options. I would probably could create a view model that contains both of your models:
public class CustomerViewModel
{
public CustomerFoodModel FoodModel { get; set; }
public CustomerHistoryModel HistoryModel { get; set; }
}
Or, depending on your data structure, you may have multiple history entries per customer:
public class CustomerViewModel
{
public CustomerFoodModel FoodModel { get; set; }
public List<CustomerHistoryModel> HistoryModels { get; set; }
}
Then your getCustomerDetails function would return a CustomerViewModel instead.

New to MVC and wanting to pass two models to the view. The idea being one is a list of data, the other is simply a datetime to show when it was last uploaded in bulk.
My models are:
public class DataModel
{
public int IDX { get; set; }
public string PyR { get; set; }
public string CN { get; set; }
public string A { get; set; }
public string B_R { get; set; }
public DateTime L_I { get; set; }
}
public class DataUpdated
{
public DateTime LastImport { get; set; }
}
And my view model is:
public class DataViewModel
{
public IEnumerable<Model.DataModel> Data { get; set; }
public Model.DataUpdated LastUploadDate { get; set; }
}
I am sending the view model to the view in the controller with:
ViewModels.DataViewModel vm = new ViewModels.DataViewModel();
vm.Data = C_List;
vm.LastUploadDate = du;
return View(vm);
I have then tried to reference this in my view, with:
#model CCA_Data.ViewModels.DataViewModel
But when I try and access the Data model from the view model in the following line of code in my view:
#foreach (var Data in Model.Data)
I get the error:
IENumerable < DataViewModel > does not contain a definition for
Data
2 questions:
What am I doing wrong?
Why does it think DataViewModel is IENumerable?
Just answering here so that others don't have to go through all of the comments...
Don't forget to Rebuild the project so that it can figure out all the namespaces and references.
I am passing back a List of objects to a webapi controller. i need to add 2 more properties, they are both Lists. I am stuck on how to setup my classes.
model/apicontroller
public class DataPoints
{
public string sqft { get; set; }
public string price { get; set; }
}
public class Products
{
public string product { get; set; }
}
public class Data
{
public string Color { get; set; }
public string Name { get; set; }
public IList<DataPoints> DataPoints { get; set; }
public IList<Products> Products { get; set; }
}
public class ExportLegendController : ApiController
{
// POST: api/ExportLegend
[HttpPost]
public PDF Post([FromBody]List<Data> data)
{
here is what I am passing back
This should work as long as your JSON object has properties called dataPoints and products - whereas at the moment they're called data and product (or vice versa of course, you could rename your .NET model.)
I also find IEnumerables are more reliably deserialised.
How can I fetch and insert data at a specific time in one view in mvc razor view? I mean to fill a dropdown list from the database in create view.
I want to fill the following when I add the subject and cheater models.
department list
semester list
standard list
stream list
cheater model:
namespace firstapp.Models
{
public class chepter
{
[ForeignKey("dip_id")]
public int dipart_id { get; set; }
public int chep_id { get; set; }
public string subject { get; set; }
public string chepter { get; set; }
public List<dipartment> dipartlist { get; set; }
public List<dipartment> stdlist { get; set; }
public List<dipartment> semlist { get; set; }
public List<dipartment> stremlist { get; set; }
}
}
department model:
namespace firstapp.Models
{
public class dipartment
{
public int dip_id { get; set; }
public string dipart { get; set; }
public string std { get; set; }
public string sem { get; set; }
public string strem { get; set; }
}
}
#Html.DropDownListFor(model => model.dipart_id, new SelectList(Model.dipartlist.Select(s => new SelectListItem() { Value = s.dip_id, Selected = false, Text = s.dipart })), "Select")
Change your model so the list property is a selectlist:
public SelectList<dipartment> dipartlist { get; set; }
Then, when you populate the model call a service class method(you might not have a service layer, I just prefer to not have database calls in the controller)
dipartlist = _departmentService.GetAsSelectList();
The GetAsSelectList service method looks like this:
public SelectList GetAsSelectList()
{
return (from d in _context.Set<department>().OrderBy(x => x.dipart)
select new
{
Id = d.dipart_id,
Name = d.dipart
}).ToList();
}
And finally your view:
#Html.DropDownListFor(model => model.dipart_id, Model.dipartlist)
This technique means you don't have linq in either the view or controller. Also as you're only creating the selectlist in one place (the service), you can cache it with MemoryCache to prevent multiple requests for the same data. And as it looks like you're populating 4 selectlists, this might be useful.
My task is to show multiple models into a single view.I've created a ViewModel for my requirement but I'm not meeting my requirement.
please have a look into the below code and rectify me where m i going wrong ???
public partial class StudentsDetail
{
public int StudentID { get; set; }
public int ParentID { get; set; }
public string StudentName { get; set; }
public string Gender { get; set; }
public string FatherName { get; set; }
public string MotherName { get; set; }
public Nullable<System.DateTime> DateOfBirth { get; set; }
public virtual ParentsDetail ParentsDetail { get; set; }
public virtual SchoolDetail SchoolDetail { get; set; }
}
//Model 2
public partial class ParentsDetail
{
public ParentsDetail()
{
this.StudentsDetails = new HashSet<StudentsDetail>();
}
public int ParentID { get; set; }
public string Occupation { get; set; }
public string Organization { get; set; }
public string AnnualIncome { get; set; }
public virtual ICollection<StudentsDetail> StudentsDetails { get; set; }
}
//ViewModel Which I have created
public class ParentsInformationViewModel
{
public List<StudentsDetail> StudentsDetails { get; set; }
public List<ParentsDetail> ParentsDetails { get; set; }
public ParentsInformationViewModel(List<StudentsDetail> _studentDetails, List<ParentsDetail> _parentsDetails) //Should i pass all the required parameters that i want to display in view ????
{
StudentsDetails = _studentDetails;
ParentsDetails = _parentsDetails;
}
//And finally this is my method defined in the StudentController (Have i defined it in a right place/way??)
public ActionResult StudentViewModel()
{
ViewBag.ParentsDetail = new ParentsDetail(); //ParentsDetail is my controller
List<StudentsDetail> studentListObj = StudentsDetailsDAL.GetStudentDetails();
List<ParentsInformationViewModel> ParentInfoVMObj = new List<ParentsInformationViewModel>();
//foreach (var student in studentListObj)
//{
// ParentInfoVMObj.Add(new ParentsInformationViewModel(student.StudentID, student.ParentID));
//}
//ParentInfoVMObj.Add(ParentInfoVMObj); /// don't know how to call the required viewmodel
return View(ParentInfoVMObj);
}
I know that the above method of a ViewModel is wrong but how to use it or where am i going wrong I can't get.
I want to display the ViewModel in the view as a detailed view .
Please, correct me as I'm a starter in MVC3 .
Thanks In Advance!!
In your controller, define your action method as follows.
public ActionResult ParentsDetails()
{
var studentDetails = new List<StudentDetail>();
var parentDetails = new List<ParentsDetail>();
// Fill your lists here, and pass them to viewmodel constructor.
var viewModel = new ParentsInformationViewModel(studentDetails, parentDetails)
// Return your viewmodel to corresponding view.
return View(viewModel);
}
In your view define your model.
#model MySolution.ViewModels.ParentsInformationViewModel
Is there in your view declared that you are receiving model of type
In view:
#model IEnumerable<ParentsInformationViewModel>
Maybe a simple question, but I can't seem to figure it out. Saving a collection to a model when adding a model to the database isn't working. I have a site which uses asp.net MVC and entity framework.
The models:
public class Event
{
public int Id { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public ICollection<EventRange> Ranges { get; set; }
}
public class EventRange
{
public int Id { get; set; }
public string RangeName { get; set; }
public string RangeDescription { get; set; }
public int Capacitiy { get; set; }
}
The controller actions:
[HttpPost]
public ActionResult Create(Event model)
{
ICollection<EventRange> eventRanges = new Collection<EventRange>();
var range = new EventRange {RangeName = "testrange", RangeDescription = "test", Capacitiy = 5}
eventRanges.Add(range);
model.Ranges = eventRanges;
db.Events.Add(model);
db.SaveChanges();
return View();
}
public ActionResult Events()
{
return View(db.Events);
}
When setting a breakpoint in the Events action and evaluated the query, the Range isn't saved to the event:
Code Screenshot
Note that that the database created for the eventrange model by EF does save the range:
EF DB Screenshot
Am I doing something wrong?
What if you mark the Ranges property as virtual?
public virtual ICollection<EventRange> Ranges { get; set; }
