ASP.NET MVC 2问题的UpdateModel [英] ASP.NET MVC 2 problem with UpdateModel
问题描述
我想使用的UpdateModel(myItem,的FormCollection)与asp.net MVC 2,但它无法与下面的堆栈跟踪。
在System.Web.Mvc.FormCollection.GetValue(字符串名称)
在System.Web.Mvc.DefaultModelBinder.BindModel(ControllerContext controllerContext,ModelBindingContext的BindingContext)
在System.Web.Mvc.Controller.TryUpdateModel [的TModel(的TModel模型,字符串preFIX,字符串[] includeProperties,字符串[] excludeProperties,IValueProvider valueProvider)
在System.Web.Mvc.Controller.TryUpdateModel [的TModel(模型的TModel,IValueProvider valueProvider)
在Stormbreaker.Dashboard.Controllers.DashboardController`1.Update(的FormCollection集合)在D:\\项目\\ SVN \\旋风特务\\干线\\ Stormbreaker.Dashboard \\ \\控制器DashboardController.cs:23行
在lambda_method(ExecutionScope,ControllerBase,对象[])
在System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext,IDictionary`2参数)
在System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext,ActionDescriptor actionDescriptor,IDictionary`2参数)
在System.Web.Mvc.ControllerActionInvoker.<>c__DisplayClassd.<InvokeActionMethodWithFilters>b__a()
在System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodFilter(IActionFilter过滤器,ActionExecutingContext preContext,Func`1续)
我的动作看起来是这样的:
的[AcceptVerbs(HttpVerbs.Post)
[ValidateInput(假)]
公众的ActionResult更新(的FormCollection集合){
的UpdateModel(CURRENTITEM,集合);
CURRENTITEM =(T)_repository.Update(CURRENTITEM);
返回RedirectToAction(编辑,新的{PAGEPATH = CurrentItem.UrlSegment});
}
...我的表是这样的:
&LT;使用%(Html.BeginForm(更新,仪表盘,FormMethod.Post,新{NAME =editForm}))%GT;
&LT;%{%GT;
&LT; DIV&GT;
&所述;%= Html.EditorForModel()%&GT;
&LT;输入类型=提交值=保存/&GT;
&LT; / DIV&GT;
&LT;%}%GT;
这是MVC 2 RC确认的错误。如果您有的MVC源,可以去掉字符串从FormCollection.GetValue .IsNullOrEmpty()检查(),重新编译和重新部署。该班的FormCollection在的src \\ SystemWebMvc \\的mvc \\ FormCollection.cs 。该小组是意识到这一点,并修复被计划在未来preVIEW。
I'm trying to use updatemodel(myItem, formcollection) with asp.net mvc 2 but it fails with the stack trace below.
at System.Web.Mvc.FormCollection.GetValue(String name)
at System.Web.Mvc.DefaultModelBinder.BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, String prefix, String[] includeProperties, String[] excludeProperties, IValueProvider valueProvider)
at System.Web.Mvc.Controller.TryUpdateModel[TModel](TModel model, IValueProvider valueProvider)
at Stormbreaker.Dashboard.Controllers.DashboardController`1.Update(FormCollection collection) in D:\Projects\SVN\Stormbreaker\trunk\Stormbreaker.Dashboard\Controllers\DashboardController.cs:line 23
at lambda_method(ExecutionScope , ControllerBase , Object[] )
at System.Web.Mvc.ReflectedActionDescriptor.Execute(ControllerContext controllerContext, IDictionary`2 parameters)

at System.Web.Mvc.ControllerActionInvoker.<>c__DisplayClassd.<InvokeActionMethodWithFilters>b__a()
at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodFilter(IActionFilter filter, ActionExecutingContext preContext, Func`1 continuation)
My action looks like this:
[AcceptVerbs(HttpVerbs.Post)]
[ValidateInput(false)]
public ActionResult Update(FormCollection collection) {
UpdateModel(CurrentItem, collection);
CurrentItem = (T)_repository.Update(CurrentItem);
return RedirectToAction("edit", new { pagePath = CurrentItem.UrlSegment });
}
... and my form looks like this:
<% using (Html.BeginForm("Update","Dashboard", FormMethod.Post, new { name = "editForm" } )) %>
<% { %>
<div>
<%=Html.EditorForModel() %>
<input type="submit" value="Save" />
</div>
<% } %>
This is a confirmed bug in MVC 2 RC. If you have the MVC source, you can remove the String.IsNullOrEmpty() check from FormCollection.GetValue(), recompile, and redeploy. The FormCollection class is at src\SystemWebMvc\Mvc\FormCollection.cs. The team is aware of it and a fix is planned for the next preview.
