使用自定义过滤器属性 - Umbraco

Question

我有一个问题。我需要从自定义控制器和 .cshtml

中列出带有 "Active == true" 属性的子项

控制器

public class PollsController : SurfaceController
{
    private List<Theme> ThemeList()
    {
        var themePageList = Umbraco.Content(CurrentPage.Id).Children.Where("¿¿¿???");
        var themeList = new List<Theme>();

        foreach (var currentTheme in themePageList)
        {
            themeList.Add(
                new Theme
                {
                    ID = currentTheme.Id,
                    Title = currentTheme.Name,
                }
                );
        }

        return themeList;
    }
}

如果不在控制器上过滤，就像我过滤视图一样？

CSHTML

@model Encuestas.ViewModels.PollViewModel

@foreach (var currentTheme in Model.Themes.Where("¿¿¿???")
{
    <div>
        <p>
            <h1 style="text-align: center">@currentTheme.Title</h1>
        </p>
    </div>
}

谢谢！！！

编辑

public ActionResult RenderPoll()
{

    var viewModel = new PollViewModel
    {
        Themes = ThemeList()
    };

    return PartialView("~/Views/Partials/_Polls.cshtml", viewModel);

}

Answer 1

@model Encuestas.ViewModels.PollViewModel

@foreach (var currentTheme in Model.Themes(p => p.Active==true))
{
    <div>
        <p>
            <h1 style="text-align: center">@currentTheme.Title</h1>
        </p>
    </div>
}

Answer 2

更改此行：

var themePageList = Umbraco.Content(CurrentPage.Id).Children.Where("¿¿¿???");

到

var themePageList = Umbraco.TypedContent(CurrentPage.Id).Children.Where(x => x.GetPropertyValue<bool>("active"));

Umbraco.Content() 是动态类型，而 Umbraco.TypedContent() 是 IPublishedContent 类型。

您不需要在 razor 文件中过滤。
