ASP.NET MVC创建功能无法在页面上工作

本文关键字：工作 NET MVC 创建 功能 ASP | 更新日期: 2023-09-27 18:02:43

我已经创建了一个使用实体框架检索/在数据库中显示信息的页面，我还在同一页面上的部分视图中创建了功能，但它不保存/插入数据。

这是我的Home View: 

@model IEnumerable<TerminalHost.Models.buildingInfo>
@{
ViewBag.Title = "Home Page";
}
<h3>We suggest the following:</h3>
<ol class="round">
<li class="one">
    <h5>Please begin creating your network structure:</h5> <button id="modal-opener">Add a new building</button>
</li>
<li class="two">
</li>
</ol>
<div class="Container">
<div class="Box1">
    @foreach (var item in Model)
        {<div>
            <h4 class="Heading">@item.buildingName</h4>
            <h4 class="Heading">@item.buildingNumber</h4>
            <p>@item.buildingDesc1</p>
            <p>@item.buildingDesc2</p>
            <p>@item.buildingDesc3</p>
        </div>
        }
</div>
</div>
<div id="Modal" title="Building Details">
@Html.Partial("buildForm", new TerminalHost.Models.buildingInfo())
</div>

这是我的局部视图:

@model TerminalHost.Models.buildingInfo
@{
ViewBag.Title = "Create";
}
<h2>Create</h2>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
<fieldset>
<legend>buildingInfo</legend>
<div class="editor-label">
    @Html.LabelFor(model => model.buildingNumber)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.buildingNumber)
    @Html.ValidationMessageFor(model => model.buildingNumber)
</div>
....
</div>
<p>
    <input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
@Html.ActionLink("Back to List", "Index") 
</div>
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}

这是我的控制器:

public class HomeController : Controller
{
    thDB _db = new thDB();
    public ActionResult building()
    {
        var buildingModel = _db.buildings.ToList();//you have to remove the FirstOrDefault() extension method
        return View(buildingModel);
    }
    public ActionResult buildForm()
    {
        return PartialView();
    }
    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult buildForm(buildingInfo buildinginfo)
    {
        if (ModelState.IsValid)
        {
            _db.buildings.Add(buildinginfo);
            _db.SaveChanges();
            return RedirectToAction("Index");
        }
        return PartialView(buildinginfo);
    }

    protected override void Dispose(bool disposing)
    {
        if(_db != null)
        {
            _db.Dispose();
        }
        base.Dispose(disposing);
    }
}

我已经尝试复制相同的代码作为脚手架模板，是创建做CRUD功能，但他们被分开到不同的视图，而我希望他们都在一个页面上。

你需要的是告诉你的局部视图要调用的Action。你能改一下这一行吗? 

 @using (Html.BeginForm())


 @using (Html.BeginForm("builForm","Home"))

And in your Action:

HttpPost]
[ValidateAntiForgeryToken]
public ActionResult buildForm(buildingInfo buildinginfo)
{
    if (ModelState.IsValid)
    {
        _db.buildings.Add(buildinginfo);
        _db.SaveChanges();
        return RedirectToAction("Index");
    }
    return PartialView(buildinginfo);//instead of return this you can redirect to Index so you can see the update. Just a suggestion
}
