果園自定義工作流程活動

我在Orchard中創建了一個自定義模塊，它創建了一個新的部件，類型和一個自定義活動，但我正在努力處理我需要做的最後一部分，即創建所有與特定父項目相關聯的內容項目。例如，當有人創建「Trade Show」（來自我的模塊的新類型）時，可以創建各種子頁面（路線，供應商地圖等），因爲客戶一次只運行一個節目。我需要做的是，當他們創建一個新的展會時，我想獲得最近的展會前景（我正在通過_contentManager.HqlQuery().ForType("TradeShow").ForVersion(VersionOptions.Latest).ForVersion(VersionOptions.Published).List().Last()（正面展示，這不是最有效的方式，但它的工作原理和記錄數量是〜5年後），然後找到所有那些與舊節目相關的子頁面，並將它們複製到新的內容項目中，它們必須是副本，因爲有時它們可能不得不用舊節目參考部分，？或者它可能會改變，等所有的通常的原因果園自定義工作流程活動

我如何去尋找所有引用的是，在活動之前展示的內容項這裏是我的活動滿級：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using Orchard.Autoroute.Services; 
using Orchard.ContentManagement; 
using Orchard.Localization; 
using Orchard.Projections.Models; 
using Orchard.Projections.Services; 
using Orchard.Workflows.Models; 
using Orchard.Workflows.Services; 
using Orchard.Workflows.Activities; 

namespace Orchard.Web.Modules.TradeShows.Activities 
{ 
public class TradeShowPublishedActivity : Task 
{ 
    private readonly IContentManager _contentManager; 
    private readonly IAutorouteService _autorouteService; 
    private readonly IProjectionManager _projectionManager; 

    public TradeShowPublishedActivity(IContentManager contentManager, IAutorouteService autorouteService, IProjectionManager projectionManager) 
    { 
     _contentManager = contentManager; 
     _autorouteService = autorouteService; 
     _projectionManager = projectionManager; 

     T = NullLocalizer.Instance; 
    } 

    public Localizer T { get; set; } 

    public override LocalizedString Category 
    { 
     get { return T("Flow"); } 
    } 

    public override LocalizedString Description 
    { 
     get { return T("Handles the automatic creation of content pages for the new show."); } 
    } 

    public override string Name 
    { 
     get { return "TradeShowPublished"; } 
    } 

    public override string Form 
    { 
     get { return null; } 
    } 

    public override IEnumerable<LocalizedString> GetPossibleOutcomes(WorkflowContext workflowContext, ActivityContext activityContext) 
    { 
     yield return T("Done"); 
    } 

    public override IEnumerable<LocalizedString> Execute(WorkflowContext workflowContext, ActivityContext activityContext) 
    { 
     var priorShow = _contentManager.HqlQuery().ForType("TradeShow").ForVersion(VersionOptions.Latest).ForVersion(VersionOptions.Published).List().Last(); 
     var tradeShowPart = priorShow.Parts.Where(p => p.PartDefinition.Name == "TradeShowContentPart").Single(); 

     //new show alias 
     //workflowContext.Content.ContentItem.As<Orchard.Autoroute.Models.AutoroutePart>().DisplayAlias 

     yield return T("Done"); 
    } 
}

}

我Migrations.cs文件設置一個用於子頁面引用父秀這樣的部分：

ContentDefinitionManager.AlterPartDefinition("AssociatedTradeShowPart", builder => builder.WithField("Trade Show", cfg => cfg.OfType("ContentPickerField") 
                                    .WithDisplayName("Trade Show") 
                                    .WithSetting("ContentPickerFieldSettings.Attachable", "true") 
                                    .WithSetting("ContentPickerFieldSettings.Description", "Select the trade show this item is for.") 
                                    .WithSetting("ContentPickerFieldSettings.Required", "true") 
                                    .WithSetting("ContentPickerFieldSettings.DisplayedContentTypes", "TradeShow") 
                                    .WithSetting("ContentPickerFieldSettings.Multiple", "false") 
                                    .WithSetting("ContentPickerFieldSettings.ShowContentTab", "true")));

然後，創建我的子頁面（只有一個了，但還有更多的來臨）像這樣：

ContentDefinitionManager.AlterTypeDefinition("ShowDirections", cfg => cfg.DisplayedAs("Show Directions") 
                       .WithPart("AutoroutePart", builder => builder.WithSetting("AutorouteSettings.AllowCustomPattern", "true") 
                                   .WithSetting("AutorouteSettings.AutomaticAdjustmentOnEdit", "false") 
                                   .WithSetting("AutorouteSettings.PatternDefinitions", "[{Name:'Title', Pattern: '{Content.Slug}', Description: 'international-trade-show'}]") 
                                   .WithSetting("AutorouteSettings.DefaultPatternIndex", "0")) 
                       .WithPart("CommonPart", builder => builder.WithSetting("DateEditorSettings.ShowDateEditor", "false")) 
                       .WithPart("PublishLaterPart") 
                       .WithPart("TitlePart") 
                       .WithPart("AssociatedTradeShowPart") /* allows linking to parent show */ 
                       .WithPart("ContainablePart", builder => builder.WithSetting("ContainablePartSettings.ShowContainerPicker", "true")) 
                       .WithPart("BodyPart"));

所以，你必須在展會內容項目，下一步將是找到一個ContentPickerField所有部分，再往下篩選列表中那些字段包含你的節目的ID。

 var items = _contentManager.Query().List().ToList() // Select all content items 
      .Select(p => (p.Parts 
       // Select all parts on content items 
      .Where(f => f.Fields.Where(d => 
       d.FieldDefinition.Name == typeof(ContentPickerField).Name && 
       // See if any of the fields are ContentPickerFields 
       (d as ContentPickerField).Ids.ToList().Contains(priorShow.Id)).Any()))); 
        // That field contains the Id of the show

這可能會變得很貴，具體取決於數據庫中有多少內容項目。
