我正在使用 MVC 4 和实体框架开发 Intranet Web 应用程序。从开发开始，我就有一个我无法解决的问题。为了说明我在说什么，这里有一个例子：
我可以通过“创建视图”添加一个人。在这个观点中，我必须精确一个十进制数，它代表这个人的房子和工作地点之间的距离。在这个阶段，一切都很好。但是，当我想编辑一个人并想保存更改时，该数字不被接受为十进制数。
我阅读了我的问题，并尝试了在 web.config 中添加标签和精确我想要使用的文化（准确地说是法国文化）。
这是我的“编辑视图”：
@model BuSIMaterial.Models.Person
@{
ViewBag.Title = "Edit";
}
<h2>
Edit</h2>
<script src="@Url.Content("~/Scripts/jQueryFixes.js")" type = "text/javascript"></script>
@using (Html.BeginForm())
{
@Html.ValidationSummary(true)
<fieldset>
<legend>Person</legend>
@Html.HiddenFor(model => model.Id_Person)
<div class="editor-label">
First name :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.FirstName, new { maxlength = 50 })
@Html.ValidationMessageFor(model => model.FirstName)
</div>
<div class="editor-label">
Last name :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.LastName, new { maxlength = 50 })
@Html.ValidationMessageFor(model => model.LastName)
</div>
<div class="editor-label">
National number :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.NumNat, new { maxlength = 11 })
@Html.ValidationMessageFor(model => model.NumNat)
</div>
<div class="editor-label">
Start date :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.StartDate, new { @class = "datepicker" })
@Html.ValidationMessageFor(model => model.StartDate)
</div>
<div class="editor-label">
End date :
</div>
<div class="editor-field">
@Html.TextBoxFor(model => model.EndDate, new { @class = "datepicker" })
@Html.ValidationMessageFor(model => model.EndDate)
</div>
<div class="editor-label">
Distance House - Work (km) :
</div>
<div class="editor-field">
@Html.EditorFor(model => model.HouseToWorkKilometers)
@Html.ValidationMessageFor(model => model.HouseToWorkKilometers)
</div>
<div class="editor-label">
Category :
</div>
<div class="editor-field">
@Html.DropDownList("Id_ProductPackageCategory", "Choose one ...")
@Html.ValidationMessageFor(model => model.Id_ProductPackageCategory) <a href="../ProductPackageCategory/Create">
Add a new category?</a>
</div>
<div class="editor-label">
Upgrade? :
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Upgrade)
@Html.ValidationMessageFor(model => model.Upgrade)
</div>
<p>
<input type="submit" value="Save" />
</p>
</fieldset>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
你有解决这个问题的想法吗？这很烦人，不幸的是，我没有找到解决它的方法。
编辑：编辑方法（人控制器）：
public ActionResult Edit(long id = 0)
{
Person person = db.Persons.Single(p => p.Id_Person == id);
if (person == null)
{
return HttpNotFound();
}
ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name", person.Id_ProductPackageCategory);
return View(person);
}
//
// POST: /Person/Edit/5
[HttpPost]
public ActionResult Edit(Person person)
{
ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name", person.Id_ProductPackageCategory);
if (ModelState.IsValid)
{
ModelStateDictionary errorDictionary = Validator.isValid(person);
if (errorDictionary.Count > 0)
{
ModelState.Merge(errorDictionary);
return View(person);
}
db.Persons.Attach(person);
db.ObjectStateManager.ChangeObjectState(person, EntityState.Modified);
db.SaveChanges();
return RedirectToAction("Index");
}
return View(person);
}
