Razor view engine - How can I add Partial Views

问题:

I was wondering what, if it is possible, is the best way to render a partial using the new razor view engine. I understand this is something that wasn't finished completely by the time

Right now I am using RenderPage to render the user control:

@RenderPage("~/Views/Shared/LocaleUserControl.cshtml",ViewData.Model)

The page calling RenderPage uses a layout (master) page with three sections defined: TitleContent, HeadContent and Maincontent. When I attempt to render my locale control from this page it appears that these sections are also required - they should only be required in the calling page and are present. I receive the following message, regardless of whether or not I include the sections in my partial view (obviously I dont want to include these sections but it seemed like an interesting debugging point...).

The following sections have been defined but have not been rendered on the layout page '~/Views/Shared/LocaleUserControl.cshtml': TitleContent; HeadContent; MainContent

My partial view is as follows (adapted from the following link):

@inherits System.Web.Mvc.WebViewPage<LocaleBaseModel>
@using System.Web.UI;

<p>
     @Html.LabelFor(model => Model.CountryName)
    <br />
    @Html.DropDownListFor(model => Model.CountryName,null, string.Empty, new { @class = "text", accesskey="u"})
</p>
<p>
     @Html.LabelFor(model => Model.StateProvince)
    <br />
     @Html.DropDownListFor(model => Model.StateProvince, null, string.Empty, new { @class = "text", accesskey="t" })
</p>


<script type="text/javascript">
    $(function () {
        var countries = $("#CountryName");
        var statesprovinces = $("#StateProvince");
        countries.change(function () {
            statesprovinces.find('option').remove();
            var url = '@Url.Action("GetStatesProvinces", "Base")';
            $.getJSON(url, { countryId: countries.val() }, function (data) {
                $(data).each(function () {
                    $("<option value=" + this.ID + ">" + this.Name + "</option>").appendTo(statesprovinces);
                });
            });
        });
    });
</script>

回答1:

You partial looks much like an editor template so you could include it as such (assuming of course that your partial is placed in the ~/views/controllername/EditorTemplates subfolder):

@Html.EditorFor(model => model.SomePropertyOfTypeLocaleBaseModel)

Or if this is not the case simply:

@Html.Partial("nameOfPartial", Model)

If you don't want to duplicate code, and like me you just want to show stats, in your view model, you could just pass in the models you want to get data from like so:

public class GameViewModel
{
    public virtual Ship Ship { get; set; }
    public virtual GamePlayer GamePlayer { get; set; }     
}

Then, in your controller just run your queries on the respective models, pass them to the view model and return it, example:

GameViewModel PlayerStats = new GameViewModel();

GamePlayer currentPlayer = (from c in db.GamePlayer [more queries]).FirstOrDefault();

[code to check if results]

//pass current player into custom view model
PlayerStats.GamePlayer = currentPlayer;

Like I said, you should only really do this if you want to display stats from the relevant tables, and there's no other part of the CRUD process happening, for security reasons other people have mentioned above.
