我是相当新的MVC所以请多多包涵。
我手头的目标是张贴含有称为“验证”来使用Ajax我的控制器属性checkboxfor HTML帮手。 我做的研究土堆，并取得了这个职位非常类似，但它仍然没有达到控制器，而是我收到一个505错误。 checkboxfor阿贾克斯链接 。 这个帖子没有显示控制器如何处理被传递到数据，我带领相信这可能是我的问题，但我不能肯定。 或者，它可能是一些与在foreach块做一些怪异的东西。（边注上表中，我们使用的表格格式datatables.net库）。 下面是我的代码...
模型（直接从EF实体类来得快，经由元数据带来的）
namespace Entities
{
public class FPDrinkingWater : AccessibleRecord<FPDrinkingWater>
{
public FPDrinkingWater();
public bool Approved { get; set; }
public string ApprovedBy { get; set; }
public DateTime? ApprovedDate { get; set; }
public string Clorinated { get; set; }
public DateTime? CollectionDate { get; set; }
public TimeSpan? CollectionTime { get; set; }
public string Collectors { get; set; }
public string Comments { get; set; }
public override string CreatedBy { get; set; }
public override DateTime CreatedDate { get; set; }
public bool Deleted { get; set; }
public bool EC { get; set; }
public override int Id { get; set; }
public string Location { get; set; }
public bool RAG { get; set; }
//
// Summary:
// Drinking water record
public override string RecordName { get; }
public short? Replicate { get; set; }
public virtual SampleLog SampleLog { get; set; }
public int SID { get; set; }
public bool SWAT_LAB { get; set; }
public bool TIMS { get; set; }
public override string UpdatedBy { get; set; }
public override DateTime? UpdatedDate { get; set; }
public bool Verified { get; set; }
public string VerifiedBy { get; set; }
public DateTime? VerifiedDate { get; set; }
public override void UpdateTo(FPDrinkingWater entity);
protected override void ParameterChecks();
}
}
控制器的动作来填充观点：
//unverified Drinking Water log
[OpenAction]
public async Task<ActionResult> UnverifiedDrinkingWaterLog(AlertModel alert)
{
//return partial Drinking water log view
return await UnverifiedDataTableAsync<FPDrinkingWater>(alert);
}
定义UnverifiedDataTableAsync ：
//Unverified data table
[OpenAction]
public async Task<ActionResult> UnverifiedDataTableAsync<TEntity>(AlertModel alert, string viewName = null) where TEntity : class
{
// get data
var data = (from a in await LimsManager.AllAsync<TEntity>()
select a).ToList();
//LimsManager.AllAsync returns the entire context contents of the Entity in a List then the view tests if `Verified` is not populated.
// create sample log model with alert
var response = new TableModel<TEntity>
{
Alert = alert,
Data = data
};
// return partial data view
return PartialView(viewName ?? $"_Unverified{typeof(TEntity).Name}Table", response);
}
控制器更新动作：
[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> VerifyDrinkingWater(FPDrinkingWater drinkingWater, string id )
{
//create alert model
var response = new AlertModel();
//check model state
if(ModelState.IsValid)
{
//add the verifier to the DrinkingWater record
drinkingWater.Verified = true;
drinkingWater.VerifiedBy = User.Identity.Name;
drinkingWater.VerifiedDate = DateTime.Now;
//update the drinking water with the new verified information
var result = await LimsManager.UpdateAsync(drinkingWater);
//check update result
if(result.Succeeded)
{
response.AddInfo($"All SID's successfully verified in the database.", BSContextualTypes.success);
}
else
{
//add failure to alert
response.AddInfo($"Unable to verify SID's in database.", BSContextualTypes.warning);
}
}
else
{
InvalidState(response);
}
return await UnverifiedDrinkingWaterLog(response);
}
视图应遍历实体的背景下，建设了表中的每个记录发现未经验证：
@model MyProgram.Application.TableModel<Entities.FPDrinkingWater>
@{
Layout = null;
var insertionMode = InsertionMode.Replace;
var fail = "displayFailure";
var target = "UnverifiedDrinkingWaterContent";
var ajax = "UnverifiedDrinkingWaterLogLoader";
var verify = Html.UserHasClaim("FP/DrinkingWater/VerifyDrinkingWater");
}
<br />
@if (Model != null && Model.Alert != null && Model.Alert.Message != null)
{
@Html.Alert(Model.Alert)
}
@MyHelper.Loader(ajax)
<table id="UnverifiedDrinkingWaterTable" class="table table-hover">
<thead>
<tr>
<th>@Html.LabelFor(m => m.Data.FirstOrDefault().SID)</th>
<th>@Html.LabelFor(m => m.Data.FirstOrDefault().Location)</th>
<th>@Html.LabelFor(m => m.Data.FirstOrDefault().Replicate)</th>
<th>@Html.LabelFor(m => m.Data.FirstOrDefault().CollectionDate)</th>
<th>@Html.LabelFor(m => m.Data.FirstOrDefault().CollectionTime)</th>
<th>@Html.LabelFor(m => m.Data.FirstOrDefault().Collectors)</th>
<th>@Html.LabelFor(m => m.Data.FirstOrDefault().Clorinated)</th>
<th>@Html.LabelFor(m => m.Data.FirstOrDefault().Comments)</th>
<th>@Html.LabelFor(m => m.Data.FirstOrDefault().Verified)</th>
</tr>
</thead>
<tbody>
@if (Model.Data.Any(v => !v.Verified))
{
foreach (var log in Model.Data.Where(v => !v.Verified))
{
<tr data-record-id="@log.Id">
<td>@log.SID</td>
<td>@log.Location</td>
<td>@log.Replicate</td>
<td>@log.CollectionDate.Value.ToShortDateString()</td>
<td>@log.CollectionTime</td>
<td>@log.Collectors</td>
<td>@log.Clorinated</td>
<td>@log.Comments</td>
<td>@Html.CheckBoxFor(m => log.Verified, new { data_url = Url.Action("VerifyDrinkingWater", "DrinkingWater"), id = "mycheckbox", @class = "toggle" })</td>
</tr>
}
}
else
{
<tr>
<td colspan="@Html.ColumnCount(3)"><em>No Drinking Water data to verify.</em></td>
</tr>
}
</tbody>
</table>
<hr />
@if (Model.Data.Count > 0)
{
<script>
$(document).ready(function () {
makeDataTable('UnverifiedDrinkingWaterTable');
$(function () {
$('.toggle').change(function () {
var self = $(this);
var url = self.data('url');
var id = self.attr('id');
var value = self.prop(':checked');
$.ajax({
url: url,
data: { id: id },
type: 'POST',
success: function (result) {
alert(response)
}
});
});
});
});
</script>
}
生成的HTML：
<tr data-record-id="3" role="row" class="odd">
<td>5</td>
<td>Location</td>
<td>1</td>
<td>3/31/1997</td>
<td>18:00:00</td>
<td>YY</td>
<td>Y</td>
<td></td>
<td><input class="toggle" data-url="/FP/DrinkingWater/VerifyDrinkingWater" data-val="true" data-val-required="The Verified field is required." id="mycheckbox" name="log.Verified" type="checkbox" value="true"><input name="log.Verified" type="hidden" value="false"></td>
</tr>
和data-record-id在数据库中的那些相匹配。
