Question

我有一个场景，我需要在一个表中存储多行。让我详细解释一下。

我有表格 Price，其 4列，ID, ModelID, AppSettingID,Amount。

我正在寻找向表格中插入多个值

ID将是主键。
所有行的ModelID都相同。
AppSettingID和Amount对于所有行都是不同的，并且将基于用户在视图上的选择。

我已将AppSettingID绑定到视图上的不同组合框，因为我将其分类到数据库中。

这就是我现在正在做的事情。

查看：

<div class="editor-label">
        @Html.LabelFor(model => model.ModelID, "Model")
    </div>
    <div class="editor-field">
        @Html.DropDownList("ModelID", String.Empty)
        @Html.ValidationMessageFor(model => model.ModelID)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.AppsettingID, "Mobile Condition")
    </div>

    <div class="editor-field">
        @Html.DropDownList("Mobile Condition", new       SelectList(ViewBag.ConditionID, "Text", "Value"))
        @Html.ValidationMessageFor(model => model.AppsettingID)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.Amount)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Amount)
        @Html.ValidationMessageFor(model => model.Amount)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.AppsettingID, "Tennure")
    </div>

    <div class="editor-field">
        @Html.DropDownList("Tennure", new SelectList(ViewBag.AppsettingID, "TexT", "Value"))
        @Html.ValidationMessageFor(model => model.AppsettingID)
    </div>

    <div class="editor-label">
        @Html.LabelFor(model => model.Amount)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.Amount)
        @Html.ValidationMessageFor(model => model.Amount)
    </div>

    <p>
        <input type="submit" value="Create" />
    </p>

控制器：

public ActionResult Create()
    {
        //ViewBag.AppsettingID = db.Appsettings.Select(r => r.ID).Distinct();
        ViewBag.ModelID = new SelectList(db.Models, "ID", "Name");
        //ViewBag.Tennure = db.Appsettings.Select(s => s.Type == "Tennure").Distinct();

        IQueryable<Appsetting>TennureIDs = db.Appsettings.Where(s => s.Type == "Tennure").Distinct();
        IQueryable<Appsetting> Conditions = db.Appsettings.Where(s => s.Type == "Mobile Condition").Distinct();

        List<SelectListItem> items = new List<SelectListItem>();
        foreach (var t in TennureIDs)
        {
            SelectListItem s = new SelectListItem();
            s.Text = t.ID.ToString();
            s.Value = t.Value.ToString();
            items.Add(s);
        }
        ViewBag.AppsettingID = items;

        List<SelectListItem> conds = new List<SelectListItem>();
        foreach (var t in Conditions)
        {
            SelectListItem s = new SelectListItem();
            s.Text = t.ID.ToString();
            s.Value = t.Value.ToString();
            conds.Add(s);
        }

        ViewBag.ConditionID = conds;

        return View();
    }

    //
    // POST: /Price/Create

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create(Price price, FormCollection form)
    {
        if (ModelState.IsValid)
        {
            int test = Convert.ToInt16(form["Mobile Condition"]);
            price.AppsettingID = test;
            db.Prices.Add(price);
            db.SaveChanges();
            return RedirectToAction("Index");
        }

        //ViewBag.AppsettingID = new SelectList(db.Appsettings, "ID", "Type", price.AppsettingID);
        //ViewBag.ModelID = new SelectList(db.Models, "ID", "Name", price.ModelID);
        return View(price);
    }

我希望这个解决方案可以帮到你

以下是剃刀页面，这里我以表格格式显示模型

@model List<MyModel>

<h2>Create</h2>

@using (Html.BeginForm())
{
    <table>
        <tr>
            <th>
                Model ID
            </th>
            <th>
                App Setting ID
            </th>          
            <th>
                Amount
            </th>            
        </tr>

        @for (int i = 0; i < Model.Count; i++)
        {
            <tr>
                <td>
                    @Html.TextBoxFor(x => Model[i].ModelID)
                </td>
                <td>
                    @Html.TextBoxFor(x => Model[i].AppsettingID)
                </td>
                <td>
                    @Html.TextBoxFor(x => Model[i].Amount)
                </td>
            </tr>                    
        }
    </table>
    <input type="submit" />
}

当用户点击提交按钮时，它会将模型传递给控制器

<强>控制器

    [HttpPost]
    public ActionResult Create(List<MyModel> m)
    {
        // Do Coding
        return View("Create", m);
    }

使用MVC Razor Views在表中插入多行
