可能在这里遗漏了一些明显的东西,但我发布到 Controller 的模型始终为空...模型正确传递到 View 并且我可以访问属性,但是在提交表单时,模型为空。为什么?
模型...
public class ProfileModel
{
public MembershipUser user { get; set; }
public ProfileSettingsModel settings { get; set; }
}
Controller ...
[HttpPost]
public ActionResult SaveSettings(ProfileModel model)
{
var x = model.user.UserName;
return View();
}
查看...
@model MyApp.Models.Profile.ProfileModel
@using(Html.BeginForm("SaveSettings","Profile"))
{
//Tried removing these as I shouldn't need them, but no luck.
@Html.HiddenFor(x=>x.settings)
@Html.HiddenFor(x=>x.user)
@Html.CheckBoxFor(model=>model.settings.VisitorsCanAddMeAsFriend)
@Html.LabelFor(x=>x.settings.VisitorsCanAddMeAsFriend, "Visitors can add me as a friend")
@Html.CheckBoxFor(x=>x.settings.VisitorsCanMessageMe)
@Html.LabelFor(x=>x.settings.VisitorsCanMessageMe, "Visitors can message me")
<button id="save" type="submit" class="btn btn-default">Save</button>
}
呈现的 HTML...
<form action="/Profile/SaveSettings?HttpMethod=POST&InsertionMode=Replace&LoadingElementDuration=0&AllowCache=False" method="post" novalidate="novalidate">
<input data-val="true" data-val-required="The VisitorsCanAddMeAsFriend field is required." id="settings_VisitorsCanAddMeAsFriend" name="settings.VisitorsCanAddMeAsFriend" type="checkbox" value="true">
<input name="settings.VisitorsCanAddMeAsFriend" type="hidden" value="false">
<label for="settings_VisitorsCanAddMeAsFriend">Visitors can add me as a friend</label>
<input data-val="true" data-val-required="The VisitorsCanMessageMe field is required." id="settings_VisitorsCanMessageMe" name="settings.VisitorsCanMessageMe" type="checkbox" value="true">
<input name="settings.VisitorsCanMessageMe" type="hidden" value="false">
<label for="settings_VisitorsCanMessageMe">Visitors can message me</label>
<button id="save" type="submit" class="btn btn-default">Save</button>
</form>
有什么明显的吗?
最佳答案
您不能在模型绑定(bind)中使用 MembershipUser。模型绑定(bind)要求所有属性都有一个公共(public)的无参数构造函数,MembershipUser 的无参数构造函数是 protected 。因此,您不能直接使用它。您将需要创建自己的 View 模型来传递属性。
因此,删除设置和用户 HiddenFor's,然后直接对这些属性进行出价将获得您想要的结果。
