在MVC 4模型提交表单是控制器POST方法无效 [英] Submitting Form in MVC 4 model is null in controller post method
问题描述
所以我的问题,现在的问题是,我不能让我的模式进入我的控制器,当我提交这份以下表格。我想有从开票codeS(即开票codeObjects列表)遍历和显示的项目。我已删除了这些不在的情况确实有些相关code,使其更短,更易于阅读。
So my problem right now is that I cant get my model into my controller when I submit this following form. I am trying to have the items from the BillingCodes (which is a list of BillingCodeObjects) loop through and display. I have removed some code from these that isn't really relevant to the situation to make it shorter and easier to read.
下面是code对我的看法...
Here is the code for my view...
@using (Html.BeginForm("SubmitTimesheet", "Timesheet", FormMethod.Post))
{
foreach (var item in Model.BillingCodes)
{
<div class="button-padding">
<a class="btn btn-large btn-danger btn-block billCodeBtn">
<div class="btnText">@item.Name</div>
<div class="btnTime">@item.TotalHours</div>
<i class="icon-chevron-down billCodeIconUp billCodeIcon"></i>
<i class="hidden icon-chevron-up billCodeIconDown billCodeIcon"></i>
</a>
<div class="content" >
<div class="row timeEntry">
<p></p>
<div class="col-12 col-lg-2">
Enter Time:
<div class="row">
<div class="col-12">
@Html.DropDownListFor(model => item.EnterTimeHours, new SelectList(new[] {
new { Value = "0", Text = "0" },
new { Value = "1", Text = "1" },
new { Value = "2", Text = "2" },
new { Value = "3", Text = "3" },
new { Value = "4", Text = "4" },
new { Value = "5", Text = "5" },
new { Value = "6", Text = "6" },
new { Value = "7", Text = "7" },
new { Value = "8", Text = "8" },
new { Value = "9", Text = "9" },
new { Value = "10", Text = "10" },
new { Value = "11", Text = "11" },
new { Value = "12", Text = "12" },
}, "Value", "Text")) <b>:</b>
@Html.DropDownListFor(model => item.EnterTimeMinutes, new SelectList(new[] {
new { Value = "0", Text = "00" },
new { Value = "15", Text = "15" },
new { Value = "30", Text = "30" },
new { Value = "45", Text = "45" },
}, "Value", "Text"))
</div>
</div>
</div>
<div class="col-lg-2"></div>
<div class="col-lg-1"></div>
<div class="control-group col-12 col-lg-2">
<label class="checkbox">
Billable @Html.CheckBoxFor(model => item.Billable)
</label>
</div>
<div class="col-12 col-lg-2">
Enter Memo:
<div class="row">
<div class="col-12">
@Html.TextAreaFor(model => item.Comment)
</div>
</div>
和这里是一些code为我的控制器:
And here is some code for my controller:
public class TimesheetController : Controller
{
//
// GET: /Timesheet/
public ActionResult Index()
{
string getBillingCodeUrl ="";
//SOME CODE REMOVED FOR LENGTH / READABILITY
foreach (var entryItem in timePeriod.TimeEntries[0].EntryCollection)
{
foreach (var billingItem in billingCodeList.BillingCodes)
{
if (entryItem.BillingCode == billingItem.Name)
{
//update record in billingItem with data from entryItem
billingItem.Comment = entryItem.Comment;
billingItem.Billable = entryItem.Billable;
billingItem.TotalHours = entryItem.Hours;
}
}
}
return View(billingCodeList);
}
[HttpPost]
public void SubmitTimesheet(BillingCodeList model)
{
string uri = "";
foreach (var billingCode in model.BillingCodes)
{
//do stuff with each of these
}
}
}
}
和最后,这里要说的是在模型的信息:
and lastly, here is the info that is in the model:
public class BillingCodeList
{
public List<BillingCodeObj> BillingCodes;
}
public class BillingCodeObj
{
public string Name { get; set; }
public decimal TotalHours { get; set; }
public decimal EnterTimeHours { get; set; }
public decimal EnterTimeMinutes { get; set; }
public bool Billable { get; set; }
public string Comment { get; set; }
public BillingCodeObj(string name, decimal hours)
{
this.Name = name;
this.TotalHours = hours;
}
public BillingCodeObj()
{
}
}

推荐答案
您正在做的意见的foreach,所以输入元素应该有张贴的地方像这个值: NAME =结算codeS [0] .EnterTimeHours
, NAME =结算codeS [0] .EnterTimeMinutes
您可以在网络选项卡上的检查Chrome开发者工具(CTRL + SHIFT + C)的要求
或者仅仅查看源。如果是这种情况,您要提交多个开票codeObj对象。你必须有一个接收的控制器。
You are doing a foreach on the views, so the input elements should have the values posted somewhere like to this :
name="BillingCodes[0].EnterTimeHours"
, name="BillingCodes[0].EnterTimeMinutes"
you can inspect in the network tab the request on Chrome Developer Tools (CTRL+SHIFT+C)
or just viewing the source. If this is the case, you are submitting multiple BillingCodeObj objects. You must have a controller that receive that.
看看源$ C $ C,因为这可以极大地帮助你了解这是怎么回事幕后。
Take a look at the source code as this can greatly help you understand what's going on behind the scenes.
试试这个控制器上:
[HttpPost]
public void SubmitTimesheet(IEnumerable<BillingCodeObj> billingCodes){
}
您也可以(用于调试)做
You can also (for debugging purposes) do
public void SubmitTimesheet(FormCollection form){}
和检查的形式如何填充上调试。
and inspect the form how is populated on debug.
后的意见和更多code提供
改变你的看法为:
after comments and more code provided change your view to :
@using (Html.BeginForm("SubmitTimesheet", "Timesheet", FormMethod.Post))
{
@Html.EditorFor(m=>m.BillingCodes)
}
创建EditorTemplates /计费codeObj.cshtml新CSHTML:
create a new cshtml in EditorTemplates/BillingCodeObj.cshtml :
@model BillingCodeObj
<div class="button-padding">
<a class="btn btn-large btn-danger btn-block billCodeBtn">
<div class="btnText">@Model.Name</div>
<div class="btnTime">@Model.TotalHours</div>
<i class="icon-chevron-down billCodeIconUp billCodeIcon"></i>
<i class="hidden icon-chevron-up billCodeIconDown billCodeIcon"></i>
</a>
<div class="content" >
<div class="row timeEntry">
<p></p>
<div class="col-12 col-lg-2">
Enter Time:
<div class="row">
<div class="col-12">
@Html.DropDownListFor(model => model.EnterTimeHours, new SelectList(new[] {
new { Value = "0", Text = "0" },
new { Value = "1", Text = "1" },
new { Value = "2", Text = "2" },
new { Value = "3", Text = "3" },
new { Value = "4", Text = "4" },
new { Value = "5", Text = "5" },
new { Value = "6", Text = "6" },

new { Value = "10", Text = "10" },
new { Value = "11", Text = "11" },
new { Value = "12", Text = "12" },
}, "Value", "Text")) <b>:</b>
@Html.DropDownListFor(model => model.EnterTimeMinutes, new SelectList(new[] {
