我有一个控制器,用户选择一个文件,其中包含要在系统中加载的数据,但我需要验证文件尚未加载,因此我尝试创建Remote
验证
我创建了一个类:
public class FileUpload
{
[Display(Name = "Archivo")]
[Required(ErrorMessage = "Debe seleccionar un archivo.") ]
[Remote("BackupFileExist", "ImportJobs", ErrorMessage = "El archivo ya fue cargado.")]
public HttpPostedFileBase File { get; set; }
[Display(Name = "Test")]
[Required(ErrorMessage = "Debe seleccionar un archivo.")]
[Remote("BackupTestExist", "ImportJobs", ErrorMessage = "El archivo ya fue cargado.")]
public string Test { get; set; }
}
以及包含jquery.validate
和jquery.validate.unobtrusive
的强类型视图:
@using (Html.BeginForm(null, null, FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true, "", new { @class = "text-danger" })
<div class="form-group">
@Html.LabelFor(model => model.File, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.TextBoxFor(x => x.File, new { type = "file" })
@Html.ValidationMessageFor(model => model.File, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
@Html.LabelFor(model => model.Test, htmlAttributes: new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.TextBoxFor(x => x.Test, htmlAttributes: new { @class = "control-label col-md-2" })
@Html.ValidationMessageFor(model => model.Test, "", new { @class = "text-danger" })
</div>
</div>
<div class="form-group">
<div class="col-md-offset-2 col-md-10">
<input type="submit" value="Cargar Archivo" class="btn btn-default" />
</div>
</div>
</div>
}
@section scripts {
<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.min.js"></script>
<script src="http://ajax.aspnetcdn.com/ajax/mvc/4.0/jquery.validate.unobtrusive.min.js"></script>
}
然后我的控制器:
public class ImportJobsController : Controller
{
public JsonResult BackupFileExist(HttpPostedFileBase File)
{
return Json(!db.ImportJobs.Any(f => f.FileName == File.FileName),
JsonRequestBehavior.AllowGet);
}
public JsonResult BackupTestExist(string Test)
{
return Json(!db.ImportJobs.Any(f => f.FileName == Test), JsonRequestBehavior.AllowGet);
}
}
我的问题是调用BackupFileExist
函数,但File
变量为空
修改:在发布问题后,我决定添加一个类型为字符串的Test
字段。该字段按预期工作。所以看起来是File
类型
