Question

我的观点中有一个表格：

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

    <div class="form-horizontal">
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
            @Html.LabelFor(model => model.DateFrom, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.DateFrom, new { htmlAttributes = new { @class = "form-control date-picker" } })
                @Html.ValidationMessageFor(model => model.DateFrom, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.DateTo, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.DateTo, new { htmlAttributes = new { @class = "form-control date-picker" } })
                @Html.ValidationMessageFor(model => model.DateTo, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" formAction=@Url.Action("CreateReport")  />
            </div>
        </div>
        <div class="form-group">
            @Html.LabelFor(model => model.EMail, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.EMail, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.EMail, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Send to email" class="btn btn-default" formAction=@Url.Action("SendEmail") />
            </div>
        </div>
    </div>
}

正如你所看到我有两个按钮，第一个按钮调用CreateReport动作而不是发送按钮调用SendEmail动作。我想创建报告，然后通过电子邮件发送此报告。

这是我的控制器操作：

    public ActionResult Index()
    {
        Report 

report=ReportRepository.GetReport(DateTime.Parse("02.08.1996"), DateTime.Parse("07.08.1996"));
            return View(report); 
        }

        public ActionResult CreateReport(Report report)
        {
            report = ReportRepository.GetReport(report);
            return View("Index", report);
        }

        public ActionResult SendEmail(Report report)
        {
            return View("Index", report);
        }

我的模特课：

public class Report
{
    public DateTime DateFrom { get; set; }
    public DateTime DateTo { get; set; }
    public List<OrderDetails> Orders { get; set; }
    [Display(Name = "Email address")]
    [EmailAddress(ErrorMessage = "Invalid Email Address")]
    public string EMail { get; set; }
}

所以我的意思是我在CreateReport操作中填写Orders列表并显示它，然后我按下＆＃34;发送到电子邮件＆＃34;按钮，那个电话＆＃34; SendEmail＆＃34;动作，我将订单列表保存到文件并发送。

问题在于＆＃34; SendEmail＆＃34;动作列表为空。我该如何解决？

Answer 1

我能想到的最简单的方法是删除创建报告的提交操作，并使用ajax调用处理此操作。这样你只需要一次提交动作。

否则，您可以在视图中尝试使用2个表单。

就个人而言，我更喜欢第一种选择。

Answer 2

我找到了解决方案。解决方案不是将模型传递给控制器，而是将我的List存储在Session中。像这样：

    public ActionResult Index()
    {
        Report report=ReportRepository.GetReport(DateTime.Parse("02.08.1996"), DateTime.Parse("07.08.1996"));
        Session["Orders"] = report.Orders;
        return View(report); 
    }

    public ActionResult CreateReport(Report report)
    {
        report = ReportRepository.GetReport(report);
        Session["Orders"] = report.Orders;
        return View("Index", report);
    }

    public ActionResult SendEmail(Report report)
    {
        List<OrderDetails> orders = (List<OrderDetails>)Session["Orders"];
        report.Orders = orders;
        return View("Index", report);
    }
