The model item passed into the dictionary is of type... ut this dictionary requires a model item of type

Question

I'm new to exploring MVC3 and came up with a problem.

I'm editing my Master view and want the login boxes to be visible on every page when a user isn't logged in. I've done this by using this code:

@if (Request.IsAuthenticated)
        {
<text>Welcome <strong>@User.Identity.Name</strong>!
[ @Html.ActionLink("Log Off", "LogOff", "Account") ]</text>
        }
        else
        {
           Html.RenderPartial("../Account/LogOn");
        }

This works when going to my normal Index method of the HomeController.

However, when going to the Index method of my NewsController I get the following error:

The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[LeagueSite.Models.News]', but this dictionary requires a model item of type 'LeagueSite.Models.LogOnModel'.

I understand what the problem is but don't really know a sollution for it.

The view LogOn looks like this (standard MVC3 logon view):

@model LeagueSite.Models.LogOnModel

@{
    ViewBag.Title = "Log On";
}

<h2>Login</h2>
<p>
    Please enter your user name and password. @Html.ActionLink("Register", "Register") if you don't have an account.
</p>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@Html.ValidationSummary(true, "Login was unsuccessful. Please correct the errors and try again.")

@using (Html.BeginForm()) {
    <div>
        <fieldset>
            <legend>Account Information</legend>

            <div class="editor-label">
                @Html.LabelFor(m => m.UserName)
            </div>
            <div class="editor-field">
                @Html.TextBoxFor(m => m.UserName)
                @Html.ValidationMessageFor(m => m.UserName)
            </div>

            <div class="editor-label">
                @Html.LabelFor(m => m.Password)
            </div>
            <div class="editor-field">
                @Html.PasswordFor(m => m.Password)
                @Html.ValidationMessageFor(m => m.Password)
            </div>

            <div class="editor-label">
                @Html.CheckBoxFor(m => m.RememberMe)
                @Html.LabelFor(m => m.RememberMe)
            </div>

            <p>
                <input type="submit" value="Log On" />
            </p>
        </fieldset>
</div>

} `

Any tips/ideas?

Quick and dirty: instead of Html.RenderPartial use Html.RenderAction:

Html.RenderAction("LogOn", "Account");

and in the LogOn action of the Account controller ensure to return a PartialView or you will get a stack overflow and Cassini will crash:

public ActionResult LogOn()
{
    return PartialView();
}
