在ASP.Net MVC中使用硬编码表单在对象中插入数据

我有两张桌子Product& Orders,我做的是,我创建了View和硬编码HTML表单,将Ordered Products传递给Order对象。 保存Orders时收到错误INSERT statement conflicted with the FOREIGN KEY constraint 我也添加了断点,所有值都在Orders对象中正确填充,但是Id& Products属性为null。

我创建了一对多关系,如下图所示。 Relationship one to many between orders and products

这是我的观点

@model Myapp.Areas.Admin.ViewModel.ProductDisplayViewModel
@ViewBag.Message    
    @using (Html.BeginForm("OrderProduct", "Order"))
        {
            @Html.AntiForgeryToken()
            @Html.ValidationSummary(true)

        <div class="form-group">
            <label>Your Name</label>           
            <input id="Name" name="Name" class="form-control" type="text"/>
        </div>

            <div class="form-group">
        <label>Your Email</label>
        @Html.TextBox("Email", null, new { @class = "form-control" })
    </div>
    <div class="form-group">
        <label>Your Contact Number</label>
        @Html.TextBox("ContactNumber", null, new { @class = "form-control" })
    </div>
    <div class="form-group">
        <label>Your Address</label>
        @Html.TextBox("Address", null, new { @class = "form-control" })
    </div>
    <div class="form-group">
        <label>Quantity</label>
        @Html.TextBox("Quantity", null, new { @class = "form-control",type="Number" })
    </div>
    <div class="form-group">
        <label>Any Comments</label>
        @Html.TextBox("Comments", null, new { @class = "form-control" })
    </div>
    <div class="form-group">
    @Html.Hidden("ProductId", Model.ProductId)
    </div>
    <div class="form-group">        
        <input id="Submit1" type="submit" value="Order Now" class="read-more"/>        
        <a href="@Url.Action("Index")" class="read-more">Back to Products</a>

    </div>
        }

这是我在订单控制器中的操作方法

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult OrderProduct(Orders order)
{
    if (ModelState.IsValid)
    {
        db.Orders.Add(order);
        db.SaveChanges();
        // if Order Saved in DB show success Message and Redirect on the same product page
        ViewBag.Message = "Value Entered in DB";
        return RedirectToAction("Details", "Product", new { id = order.ProductId });
    }
    // if something went wrong Redirect on the same product page
    return RedirectToAction("Details", "Product", new { id = order.ProductId });
}

ProductId应该是产品表中的ID,按照您的定义进行,但您传递的Model.ProductId会导致您的问题。

使用您添加订单的产品中的Product.Id填充您返回的模型的ProductId字段。
