我在设置MVC 3体系结构中的一些嵌套视图时遇到了问题。这是我目前有:MVC 3问题中的嵌套视图
_Layout.cshtml
Logon.cshtml
Login.cshtml
ForgotPassword.cshtml
所以基本上,我有我的_Layout.cshtml页面,只是我的母版页。然后我有Logon.cshtml。这充当我的登录页面的“母版页”。在那之下,我有两个部分视图,Login.cshtml和ForgotPassword.cshtml。在所有这些背后,我有一个名为AccountController的控制器。首先,让我告诉你Logon.cshtml
查看/帐号/ Logon.cshtml
@model Coltrane.Web.Website.Models.Account.LogonViewModel
@{
Layout = "~/Views/Shared/_Layout.cshtml";
ViewBag.Title = "Logon";
}
@*@this.CssIncludes(@Url.Content("~/Content/login.css"))*@
@this.ScriptIncludes(@Url.Content("~/Content/scripts/Account/logon.js"))
@this.InitFunctionIncludes("lga_loginTabs.init()")
@this.InitFunctionIncludes("lga_formFocus.init()")
<div id="container">
<div class="sectionFocus noBg">
<div style="margin: 24px auto; width: 450px;">
<div class="customerLogo" style="margin: 24px auto;">
logo
</div>
<div id="tabContainer" style="position: relative; width:100%;">
<div id="login" class="box_c" style="position:absolute; width:100%;">
<h1>User Login</h1>
<div class="box_c_content">
<div class="sepH_c">
@{ Html.RenderAction("Login", "Account"); }
<a href="#" id="gotoFogot">Forgot your password?</a>
</div>
</div>
</div>
<div id="forgot" class="box_c" style="position: absolute; width:100%;display: none;">
<h1>Forgot Your Password?</h1>
<div class="box_c_content">
<div class="sepH_c">
@{ Html.RenderAction("ForgotPassword", "Account"); }
<a href="#" id="gotoLogin">Back to Login</a>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
请注意,我有渲染登录和ForgotPassword与Html.RenderAction部分景色。我这样做是因为这些实际上都是表单,他们需要发布到AccountController。接下来,让我告诉你我的Login.cshtml文件:
查看/帐号/ Login.cshtml
@model Coltrane.Web.Website.Models.Account.LoginViewModel
@{
Layout = null;
}
@this.ScriptIncludes(@Url.Content("~/Content/scripts/Account/login.js"))
@this.InitFunctionIncludes("login.init()")
<div class="sepH_a">
<label>
Please enter your email and password to log into the system.</label>
</div>
@using (Html.BeginForm("Login", "Account", FormMethod.Post, new { id = "form_login" }))
{
<div class="sepH_a">
<div class="loginError">
@Html.ValidationSummary(true, "Login was unsuccessful. Please correct the errors and try again.")
@Html.ValidationMessageFor(m => m.UserName)<br />
@Html.ValidationMessageFor(m => m.Password)
</div>
</div>
<div class="sepH_a">
@Html.LabelFor(m => m.UserName, new { @class = "lbl_a" })
<br />
@Html.TextBoxFor(m => m.UserName, new { @class = "inpt_a_login", id = "lusername", name = "lusername" })
<span class="inputReqd" style="visibility: visible;">*</span>
</div>
<div class="sepH_a">
@Html.LabelFor(m => m.Password, new { @class = "lbl_a" })
<br />
@Html.PasswordFor(m => m.Password, new { @class = "inpt_a_login", id = "lpassword", name = "lpassword" })
<span class="inputReqd" style="visibility: visible;">*</span>
</div>
<div class="sepH_a">
@Html.CheckBoxFor(m => m.RememberMe, new { @class = "input_c", id = "remember" })
@Html.LabelFor(m => m.RememberMe, new { @class = "lbl_c" })
</div>
<div class="box_c_footer">
<button class="sectB btn_a" type="submit">
Login</button>
</div>
}
正如你所看到的,这只是一个简单的形式。有一点需要注意的是,我试图在这里使用两种模型。每个观点一个。一个用于父视图,另一个用于两个子视图(忘记密码也有一个)。不管怎么说,让我告诉你我的AccountController
控制器/ AccountController.cs
public class AccountController : Controller
{
private IAuthenticationService _authenticationService;
private ILoggingService _loggingService;
public AccountController(IAuthenticationService authenticationService,
ILoggingService loggingService)
{
_authenticationService = authenticationService;
_loggingService = loggingService;
}
public ActionResult Logon()
{
return View();
}
[HttpGet]
[ChildActionOnly]
public ActionResult Login()
{
return PartialView();
}
[HttpPost]
public ActionResult Login(LoginViewModel model, string returnUrl)
{
if (ModelState.IsValid)
{
if (Membership.ValidateUser(model.UserName, model.Password))
{
FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);
if (Url.IsLocalUrl(returnUrl) && returnUrl.Length > 1 && returnUrl.StartsWith("/")
&& !returnUrl.StartsWith("//") && !returnUrl.StartsWith("/\\"))
{
return Redirect(returnUrl);
}
else
{
return RedirectToAction("Index", "Home");
}
}
else
{
ModelState.AddModelError("", "The user name or password provided is incorrect.");
}
}
else
{
ModelState.AddModelError("", "An error has occurred.");
}
// If we got this far, something failed, redisplay form
return View("Logon");
// return View(model)
// return RedirectToAction("Index", "Home");
}
//........
}
在方法[HttpPost]登录(...),我检查,看看用户是否creds是正确的。如果是这样,一切正常,但问题出在一个错误。如果我使用return View("Logon");
我认为我得到一个无限循环,如果我使用return View(model)
我获得了Login.cshtml的部分视图,并且如果使用return RedirectToAction("Index", "Home");
,我会正确返回到我的登录视图,但我添加的错误是我不知道如何使它正常工作,我想返回呈现登录。我想我的设置是有意义的,但我不知道如何使它正常工作。 ,与错误CSHTML视图只要是完整的,这里有我的两个的ViewModels为提供浏览:
public class LogonViewModel
{
}
public class LoginViewModel
{
[Required]
[Display(Name = "Email")]
public string UserName { get; set; }
[Required]
[DataType(DataType.Password)]
[Display(Name = "Password")]
public string Password { get; set; }
[Display(Name = "Remember Me?")]
public bool RememberMe { get; set; }
}
真棒!我更接近!在ImportModelStateFromTempData上,我可以看到它在呈现Logon.cshtml时遇到了这个问题,并且它获取了错误,但是当它呈现Login.cshtml(子部分视图)时,它正在触及else并将其删除。因此,我需要通过错误的观点仍然迷失。父母的观点基本上是在吃他们。思考? –
@Tyler - 由于'ViewResult'和'PartialViewResult'都扩展了'ViewResultBase',因此简单的修改就是改变'if'语句来检查结果是否为'ViewResultBase'而不是'ViewResult'类型。但是,如果您的其他部分视图也有显示错误的区域,则可能会显示两次。另一种方法是在Logon.cshtml而不是Login.cshtml上显示两个部分的错误。 –
感谢您的帮助。我最终使用了关于使用ViewResultBase的建议。我通过添加一个tempdata值和导出错误的操作名称来防止重复的错误显示。如果当前操作与tempdata中的操作匹配,则导入过滤器仅合并模型状态。我可能还会创建另一个导入/导出过滤器,并且只会使用ViewResult将错误复制到父视图。再次感谢! –
