Question

我刚开始使用MVC，我正在尝试学习如何创建订单和订单详情项目。

我还有一个包含所有项目的库存，但是我在尝试通过订单详细信息从库存中提取数据时遇到了一些问题。

如何将这两者结合在一起？ @model InventoryTest.Models.Inventory.order和 @model IEnumerable＆lt; InventoryTest.Models.Inventory.Inventories＆GT;在视图代码？

我为代码的混乱结构道歉，因为我还在学习，但我希望有人可以就我面临的问题向我提出建议。

库存模型：

public int InventoryID { get; set; }
public string ItemNo { get; set; }
public string Item { get; set; }
public int Quantity { get; set; }

订单型号：

public int OrderID { get; set; }
public DateTime Date { get; set; }
public int EmployeeID { get; set; }
public int DepartmentID { get; set; }

 public IEnumerable<SelectListItem> GetEmployee()
{
    var query = db.Employees.Select(c => new SelectListItem
    {
        Value = c.EmployeeID.ToString(),
        Text = c.DisplayName,
    });
    return query.AsEnumerable();
}

 public IEnumerable<SelectListItem> GetDeptList()
{
    var query = db.Departments.Select(c => new SelectListItem
    {
        Value = c.DepartmentID.ToString(),
        Text = c.Description,
    });
    return query.AsEnumerable();
}

订单明细模型：

public int OrderDetailID { get; set; }
public int Quantity { get; set; }
public int OrderID { get; set; }
public int InventoryID { get; set; }

在我的订单创建视图代码如下：

  @model InventoryTest.Models.Inventory.Order

@{
    ViewBag.Title = "Order Forms";
}

<h2>Order Forms</h2>


@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()


    <div class="form-horizontal">
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="row">
            <div class="col-sm-4">
                @Html.LabelFor(model => model.EmployeeID, htmlAttributes: new { @class = "control-label col-md-2" })

                <div class="col-md-offset-4">
                    @Html.ValidationMessageFor(model => model.EmployeeID, "", new { @class = "text-danger" })

                    @Html.DropDownListFor(m => m.EmployeeID, Model.GetEmployee(), "Please Select", new
               {
                   @style = "width: 200px;height:35px",
                   @class = "input-select",
                   @data_bv_notempty = "true",
                   @data_bv_message = "Please select project."
               })
                </div>
            </div>
            <div class="col-sm-4">
                @Html.LabelFor(model => model.Department, htmlAttributes: new { @class = "control-label col-md-2" })
                <div class="col-md-offset-4">
                    @Html.ValidationMessageFor(model => model.DepartmentID, "", new { @class = "text-danger" })

                    @Html.DropDownListFor(m => m.DepartmentID, Model.GetDeptList(), "Please Select", new
               {
                   @style = "width: 200px;height:35px",
                   @class = "input-select",
                   @data_bv_notempty = "true",
                   @data_bv_message = "Please select project."
               })
                </div>
            </div>
        </div>
    </div>

        <hr />
}
<br />

<h4>Item Listing</h4>

<table class="table table-hover">
    <tr>
        <th>S/N</th>
        <th>Item No.</th>
        <th>Item</th>
        <th>Quantity</th>
    </tr>


*//I want to use foreach to populate the data here*
        <tr>
            <td></td>
            <td></td>
            <td></td>
            <td></td>
            <td></td>
        </tr>

</table>
<div>
    @Html.ActionLink("Back to List", "Index")
</div>

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

Answer 1

创建一个视图模型类：

@model <your namespace goes here>.OrderAndInventoryViewModel

在您看来，请使用：

type=password id='whatever'

将适当的订单和库存信息分配到控制器中的OrderAndInventory对象，并将其传递给视图。

Answer 2

一种解决方案是创建一个新对象，称之为＆＃34; OrderViewModel＆＃34;。该对象可能包含您的订单和库存清单。然后将OrderViewModel传递给View ...

namespace InventoryTest.Models.Inventory {
    public class OrderViewModel {
        public Order order { get; set; }
        public IEnumerable<InventoryTest.Models.Inventory.Inventories> inventories { get; set; }
    }
}

然后，View顶部的@model将是

@model InventoryTest.Models.Inventory.OrderViewModel

在视图中，您可以将EmployeeID作为...

进行访问

Model.order.EmployeeID

视图中的Mvc 5 - 2模型
