The model item passed into the dictionary is of type , how i will pass orders_tables model with variable

问题

Why I got this error:

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

This is the model Orders_Tables :

public class Orders_Tables
    {
        public List<Lab_Orders>  LabOrders { get; set; }
        public List<Lab_orders_Cash> LabOrdersCash { get; set; }
        public List<Lab_Sample_status> LabOrderStatus { get; set; }

        public List<LAB_RESULTS> LabResults { get; set; }
        public List<LabTests> labtests { get; set; }
        public List<LAB_RESULTS_CLINIC_VIEW> labViewResult { get; set; }
        public List<LAB_RESULT_CASH_VIEW> labCashView { get; set; }

        public List<LAB_PARASITOLOGY_VIEW> labparaview { get; set; }

       public List<Lab_Hematology_Samples> LabSamples { get; set; }

      public List<Patients> patients { get; set; }

        public Orders_Tables()
        {
            this.LabOrders = new List<Lab_Orders>();
            this.LabOrdersCash = new List<Lab_orders_Cash>();
            this.LabOrderStatus = new List<Lab_Sample_status>();
            this.LabResults = new List<LAB_RESULTS>();
            this.labtests = new List<LabTests>();
            this.labViewResult = new List<LAB_RESULTS_CLINIC_VIEW>();
            this.labCashView = new List<LAB_RESULT_CASH_VIEW>();
            this.labparaview = new List<LAB_PARASITOLOGY_VIEW>();
            this.LabSamples = new List<Lab_Hematology_Samples>();
            this.patients = new List<Patients>();
        }


    }

This is the controller:

public ActionResult ordersCash1()
        {
            Orders_Tables tables = new Orders_Tables();

            var OrdersList = from o in tables.LabOrdersCash
                             join st in tables.LabOrderStatus on o.order_status equals st.status_id
                             where o.patient_no == (int)Session["UserpatientNo"]
                             select o;


            return View(OrdersList);
         }

this is the view code:

@model IEnumerable<AljawdahNewSite.Models.Orders_Tables>
@{
    ViewBag.Title = "ordersCash1";
    Layout = "~/Views/Shared/_LayoutPatients.cshtml";
}

<h2>Orders List</h2>

<table class="table">
        <tr>
            <td> Order No. </td>
            <td> order date    </td>
            <td> MRN Patient No  </td>
            <td> Order Status   </td>


        </tr>
        @foreach (var item in Model)
        {
            <tr>
                <td>@item.LabOrdersCash.First().cash_order_id</td>
                <td>@item.LabOrdersCash.First().order_date</td>
                <td>@item.LabOrdersCash.First().patient_no</td>
                <td>@item.LabOrderStatus.First().status_name</td>
                <td>@Html.ActionLink("Result Details", "Details1", new { id = item.LabOrdersCash.First().cash_order_id })</td>
            </tr>
        }
    </table>

how to solve this error i checked solutions in the site but its different cases ?

回答1:

In the action, try to select list of oreders Cach and sample Status and add them to tables object like the following code :

public ActionResult ordersCash1()
{
    Orders_Tables tables = new Orders_Tables();
    int patientId = (int)Session["UserpatientNo"];

    var result  = (from o in db.Lab_orders_Cash
                 join st in db.Lab_Sample_status on o.order_status equals st.status_id
                 where o.patient_no == patientId
                 select new {orederCach = o, sampleStatus = st}).ToList();

    tables.LabOrdersCash = result.Select(x => x.orederCach).ToList();
    tables.LabOrderStatus = result.Select(x => x.sampleStatus).ToList();

    return View(tables);
 }

` In the view, change the model to :

@model AljawdahNewSite.Models.Orders_Tables

You don't need to loop, if you search just the first element for LabOrdersCash and LabOrderStatus

....
    <tr>
        <td>@Model.LabOrdersCash.First().cash_order_id</td>
        <td>@Model.LabOrdersCash.First().order_date</td>
        <td>@Model.LabOrdersCash.First().patient_no</td>
        <td>@Model.LabOrderStatus.First().status_name</td>
        <td>@Html.ActionLink("Result Details", "Details1", new { id = item.LabOrdersCash.First().cash_order_id })</td>
    </tr>

I hope you find this helpful.
