How to pass two vars from one controller into one view - asp.net-mvc

Question

I want this two methods pass to one view :
public IEnumerable<ProfitAndCostViewModel> getProfitSum()
{
var profBalance = db.Profits
.Where(x => x.IdUser.UserId == WebSecurity.CurrentUserId)
.GroupBy(x => x.IdUser.UserId)
.Select(x => new ProfitAndCostViewModel { ProfitSum = x.Sum(y => y.Value) })
.ToList();
return profBalance;
}
public IEnumerable<ProfitAndCostViewModel> getCostSum()
{
var costBalance = db.Costs
.Where(x => x.IdUser.UserId == WebSecurity.CurrentUserId)
.GroupBy(x => x.IdUser.UserId)
.Select(x => new ProfitAndCostViewModel { CostSum = x.Sum(y => y.Value) })
.ToList();
return costBalance;
}
in my ActionResult I Have this:
ProfitAndCostViewModel pcv = new ProfitAndCostViewModel();
pcv.ProfModel =getProfitSum();
pcv.CostModel =getCostSum();
return View(pcv);
And in ProfitAndCostViewModel code is this:
public double ProfitSum { get; set; }
public double CostSum { get; set; }
public double FinalBalance { get; set; }
public IEnumerable<ProfitAndCostViewModel> ProfModel { get; set; }
public IEnumerable<ProfitAndCostViewModel> CostModel { get; set; }
this is the error:
The model item passed into the dictionary is of type 'WHFM.ViewModels.ProfitAndCostViewModel', but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable`1[WHFM.ViewModels.ProfitAndCostViewModel]'.

Answer 1

Create a view model which has them both;
public class BigViewModel
{
public List<ProfitsModel> ProfModel { get; set; }
public List<CostsModel> CostModel { get; set; }
}
And controller
public ActionResult Index()
{
BigViewModel model = new BigViewModel();
model.costBalance = db.Costs...;
model.profBalance = db.Profits...;
return View(model)
}

You can wrap your parameters into a ViewModel or use a ViewBag
