将部分视图模型发布到同一MVC页面

Question

From the bare-bones MVC template, I have modified Manage.cshtml to include a partial, the _AccountSettingsPartial :

<section id="accountSettings">            
    @Html.Partial("_AccountSettingsPartial")
</section>
@if (ViewBag.HasLocalPassword)
{
    @Html.Partial("_ChangePasswordPartial")
}

Manage.cshtml does not use @model anywhere, and it is loaded in AccountController.cs , in public ActionResult Manage(ManageMessageId? message) .

_AccountSettingsPartial uses @model crapplication.Models.ManagePublicSettingsViewModel and _ChangePasswordPartial uses @model crapplication.Models.ManageUserViewModel .

Originally, AccountController.cs had just a post method for ManageUserViewModel :

[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Manage(ManageUserViewModel model)

I have tried to overload it for the other partial:

[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Manage(ManagePublicSettingsViewModel model)

But this does not work, and produces the following error on a post:

System.Reflection.AmbiguousMatchException: The current request for action 'Manage' on controller type 'AccountController' is ambiguous between the following action methods:
System.Threading.Tasks.Task`1[System.Web.Mvc.ActionResult] Manage(crapplication.Models.ManagePublicSettingsViewModel) on type crapplication.Controllers.AccountController
System.Threading.Tasks.Task`1[System.Web.Mvc.ActionResult] Manage(crapplication.Models.ManageUserViewModel) on type crapplication.Controllers.AccountController

How can I make my _AccountSettingsPartial page post back data from the user account management portal?

You need to have separate forms in your partials, in order to post to different actions. (Or you could change the action of a single form with JQuery, etc., but this will be easier.)

@using (Html.BeginForm("ManagePublicSettings", "Account", FormMethod.Post))

...

@using (Html.BeginForm("ManageUser", "Account", FormMethod.Post))

You then need to uniquely name the actions.

[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> ManagePublicSettings(ManagePublicSettingsViewModel model)

...

[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> ManageUser(ManageUserViewModel model)
