从部分视图中获取模型数据

Get model data from a partial view

本文关键字:获取 模型 数据 视图      更新时间:2023-09-26

我正在使用MVC架构和实体框架(数据库优先)开发一个内部网ASP web应用程序。我的问题如下:

我有一个实体"Person"和一个实体"PhoneCard",其中包括一个外键"Person"的主键(所以,Id_Person)。我使用实体框架创建了一个CRUD控制器"PersonController",Visual Studio自动生成了相应的视图(索引、详细信息、创建、编辑和删除)。然后,我创建了另一个CRUD控制器(总是使用EF),命名为"PhoneCardController"。在我的Create Person视图中,我通过一个AJAX函数包含了Create PhoneCard视图:

function addPhoneCardCreateView() {
    $('#divCreatePhoneCard').load("@Url.Action("Create","PhoneCard")");
}

然后这样命名:

<a href = "javascript:addPhoneCardCreateView()">Add a Phone card</a>
    <div id = "divCreatePhoneCard"></div>

通过这样做,我调用了我的局部视图,这样我就可以在添加一个人的同时添加一个电话卡。不幸的是,当我单击Create按钮时,它只向数据库中添加新的人员。下面是我的PersonController中的Create动作:

        public ActionResult Create()
    {
        ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name");
        return View();
    }
    //
    // POST: /Person/Create
    [HttpPost]
    public ActionResult Create(Person person)
    {
        if (ModelState.IsValid)
        {
            db.Persons.AddObject(person);
            db.SaveChanges();
            return RedirectToAction("Index");
        }
        ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories, "Id_ProductPackageCategory", "Name", person.Id_ProductPackageCategory);
        return View(person);
    }

My Partial View:

@model BuSIMaterial.Models.PhoneCard
@{
    Layout = null;
}

您的Person模型有一个集合属性PhoneCards,在您的Post操作中始终为空,因为您不尊重naming convention for binding to a list。此外,您的PhoneCard.cshtml不是部分视图,而是完整的视图(它包含<html><body>标签,这是错误的)。

我非常推荐你following article,其中Steven Sanderson详细解释了如何实现这一目标。它使用自定义Html.BeginCollectionItem帮助器在输入字段的名称中生成非顺序索引,从而允许动态添加和删除行。
