美好的一天课程!

我正在管理帐户页面上,用户可以在其中更改密码和电子邮件。

我有一个管理视图,其中包含两个部分视图,更改密码和更改电子邮件。这两种都使用两种不同的模型。这样做的目的是在同一页面上同时包含更改密码和更改电子邮件。

如果当前密码正确,更改密码有效,但问题是当我输入错误的当前密码时。这给了我一个InvalidOperationException:

“传入字典的模型项的类型为'test.Models.LocalPasswordModel',但此字典需要类型为'test.Models.LocalEmailModel'的模型项。”

忽略瑞典语错误消息:)

这是我的模特:

public class LocalPasswordModel
{
    [Required(ErrorMessage = "Nuvarande lösenord måste fyllas i.")]
    [DataType(DataType.Password)]
    [Display(Name = "Nuvarande lösenord")]
    public string OldPassword { get; set; }

    [Required(ErrorMessage = "Nya lösenordet måste fyllas i.")]
    [StringLength(100, ErrorMessage = "Lösenordet måste vara minst 4 tecken lång.", MinimumLength = 4)]
    [DataType(DataType.Password)]
    [Display(Name = "Nya lösenordet")]
    public string NewPassword { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Bekräfta nya lösenordet")]
    [Compare("NewPassword", ErrorMessage = "De nya angivna lösenorden stämmer inte med varandra.")]
    public string ConfirmPassword { get; set; }
}

public class LocalEmailModel
{
    [Required(ErrorMessage = "Nuvarande E-postadress måste fyllas i.")]
    [DataType(DataType.EmailAddress)]
    [Display(Name = "Nuvarande E-postadress")]
    public string OldEmail { get; set; }

    [Required(ErrorMessage = "Nya E-postadressen måste fyllas i.")]
    [System.Web.Mvc.Remote("IsUserEmailAvailable", "Account", ErrorMessage = "E-postadressen används redan. Var god skriv in en annan E-postadress.")]
    [DataType(DataType.EmailAddress)]
    [Display(Name = "Nya E-postadressen")]
    public string NewEmail { get; set; }

    [DataType(DataType.EmailAddress)]
    [Display(Name = "Bekräfta nya E-postadressen")]
    [Compare("NewEmail", ErrorMessage = "De nya angivna E-postadresserna stämmer inte med varandra.")]
    public string ConfirmEmail { get; set; }
}

这是我的观点:

“父视图”:

@model test.Models.LocalPasswordModel
@{
    ViewBag.Title = "Hantera ditt konto";
}

<p class="message-success">@ViewBag.StatusMessage</p>

<p>Du är inloggad som <strong>@User.Identity.Name</strong>.</p>

<div id="Managebox1">
    @Html.Partial("_ChangePasswordPartial")
</div>

<div id="Managebox2">
    @Html.Partial("_ChangeEmailPartial")
</div>

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

“子视图,更改密码”:

@model test.Models.LocalPasswordModel

<h3>Byt lösenord</h3>

@using (Html.BeginForm("Manage", "Account")) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary()

    <fieldset>
        <legend>Change Password Form</legend>
        <ol>
            <li>
                @Html.LabelFor(m => m.OldPassword)
                @Html.PasswordFor(m => m.OldPassword)
            </li>
            <li>
                @Html.LabelFor(m => m.NewPassword)
                @Html.PasswordFor(m => m.NewPassword)
            </li>
            <li>
                @Html.LabelFor(m => m.ConfirmPassword)
                @Html.PasswordFor(m => m.ConfirmPassword)
            </li>
        </ol>
        <input type="submit" value="Byt lösenord" id="managesubmit" />
    </fieldset>
}

“子视图,更改电子邮件”:

@model test.Models.LocalEmailModel

<h3>Byt E-postadress</h3>

@using (Html.BeginForm("ManageEmail", "Account")) {
    @Html.AntiForgeryToken()
    @Html.ValidationSummary()

    <fieldset>
        <legend>Change Email Form</legend>
        <ol>
            <li>
                @Html.LabelFor(n => n.OldEmail)
                @Html.TextBoxFor(n => n.OldEmail)
            </li>
            <li>
                @Html.LabelFor(n => n.NewEmail)
                @Html.TextBoxFor(n => n.NewEmail)
            </li>
            <li>
                @Html.LabelFor(n => n.ConfirmEmail)
                @Html.TextBoxFor(n => n.ConfirmEmail)
            </li>
        </ol>
        <input type="submit" value="Byt E-postadress" id="managesubmit"/>
    </fieldset>
}

当您使用单个参数(要渲染的局部视图的名称)调用Html.Partial时,它会自动传入主视图的模型LocalPasswordModel。您需要做的事情如下:

public class ManageViewModel
{
    public ManageViewModel()
    {
        LocalPassword = new LocalPasswordModel();
        LocalEmail = new LocalEmailModel();
    }

    public LocalPasswordModel LocalPassword { get; set; }
    public LocalEmailModel LocalEmail { get; set; }
}

然后,在您的主视图中:

@model test.Models.ManageViewModel

...

<div id="Managebox1">
    @Html.Partial("_ChangePasswordPartial", Model.LocalPassword)
</div>

<div id="Managebox2">
    @Html.Partial("_ChangeEmailPartial", Model.LocalEmail)
</div>
