显示内容选择器字段中的容器部件项

Question

我有一个名为 DayTile 的内容类型，我设置了一个仅限于 HotelSection 类型的内容选择器字段。此类型是酒店类型的容器。

我想在 DayTile 选择该部分时呈现 HotelSection 中的所有酒店。这可能吗？

根据我目前的尝试，HotelSection 包含的项目似乎无法作为内容选择器字段进行访问。

如果我理解正确的话，这绝对是可能的。

您将希望覆盖 theme/module 中的 Fields.ContentPicker 视图，并且在 foreach 循环中，您希望显示该 HotelSection 的内容，而不是向每个 HotelSection 显示 link item，它将依次显示 HotelSection 中包含的所有酒店，如下所示：

@using Orchard.ContentPicker.Fields
@using Orchard.Utility.Extensions;

@{
    var field = (ContentPickerField) Model.ContentField;
    string name = field.DisplayName;
    var contentItems = field.ContentItems;
}
<p class="content-picker-field content-picker-field-@name.HtmlClassify()">
    <span class="name">@name</span>
    @if(contentItems.Any()) {
        foreach(var contentItem in contentItems) {
            @Display(contentItem.ContentManager.BuildDisplay(contentItem, "Detail"))
        }
    }
    else {
        <span class="value">@T("No content items.")</span>
    }
</p>

如果您希望直接从内容选择器字段中访问酒店，您将需要向视图中添加更多内容，有点乱，但像这样：

@using Orchard.ContentPicker.Fields
@using Orchard.Utility.Extensions;

@{
    var field = (ContentPickerField) Model.ContentField;
    string name = field.DisplayName;
    var contentItems = field.ContentItems;
}
<p class="content-picker-field content-picker-field-@name.HtmlClassify()">
    <span class="name">@name</span>
    @if(contentItems.Any()) {
        foreach(var contentItem in contentItems) {
            var container = contentItem.As<ContainerPart>();
            if(container == null) {
                continue;
            }

            var hotels = contentItem.ContentManager
                .Query(VersionOptions.Published)
                .Join<CommonPartRecord>().Where(x => x.Container.Id == container.Id)
                .Join<ContainablePartRecord>().OrderByDescending(x => x.Position);

            foreach(var hotel in hotels) {
                // do something
            }
        }
    }
    else {
        <span class="value">@T("No content items.")</span>
    }
</p>

我在顶部缺少一些 using 语句，但它的要点就在那里。

所选内容项由 ContentPickerFields ContentItems 属性公开（参见 Orchard.ContentPicker.Fields.ContentPickerField）。

要从 DayTile 内容项访问它，比方说从名为 "Content-DayTile.cshtml" 的 Razor 模板，您可以这样做：

@{
    dynamic contentItem = Model.ContentItem; // How to access the content item depends on the context. In this case, we're in a Content shape template.

   // Assuming your picker field is named "HotelSections" and attached to your DayTile content type (which in reality means it's attached to an automatically created part called "DayTile").

   var picker = contentItem.DayTile.HotelSections;
   var hotelSectionContentItems = picker.ContentItems; // Typed as IEnumerable<ContentItem>.
}

<ul>
   @foreach(var hotelSectionContentItem in hotelSectionContentItems)
   {
      // You can now either access individual parts and fields of each hotel section content item and render it, or you can choose to build a shape for each item and display that. Here are examples:  

      <li>@hotelSectionContentItem.TitlePart.Title</li>

      // or: 
      // Build a content shape for the content item.
      var hotelSectionContentShape = BuildDisplay(hotelSectionContentItem, "Summary");

     // Render the shape.
     <li>@Display(hotelSectionContentShape)</li>
}
