Question

我有一个名为event的DocumentType，它有一个名为eventCategories的属性，它是ContetPicker的NestedContent。我正在尝试在UmbracoApiController中创建一个事件 - 外部服务将填充这些事件。

我已经使用了这个要点 - https://gist.github.com/robertjf/c6d9122d90b4406b19ec - 这个问题 - Create NestedContent Items In SurfaceController - 作为我的起点。

这是我创建事件的代码（删除了不相关的属性）

 var newEvent = Services.ContentService.CreateContent(pageName, EventRootGuid, EventContentTypeAlias);

 var categories = new List<Dictionary<string, object>>();
 categories.Add(getCategory("test 1"));
 categories.Add(getCategory("test 2"));

 var pt = newEvent.PropertyTypes.FirstOrDefault(p => p.Alias == "eventCategories");
 newEvent.SetValue("eventCategories", NestedContentCreator.GenerateNestedContentValue(pt, categories));

 Services.ContentService.SaveAndPublishWithStatus(newEvent);

这会失败，因为在GetContentType函数中

    private static IContentType GetContentType(int propertyDefinitionId)
    {
        var preValueCollection = (PreValueCollection)ApplicationContext.Current.ApplicationCache.RuntimeCache.GetCacheItem(
            string.Concat("Our.Umbraco.NestedContent.GetPreValuesCollectionByDataTypeId_", propertyDefinitionId),
            () => ApplicationContext.Current.Services.DataTypeService.GetPreValuesCollectionByDataTypeId(propertyDefinitionId));

        var preValuesDict = preValueCollection.PreValuesAsDictionary.ToDictionary(x => x.Key, x => x.Value.Value);

        Guid contentTypeGuid;
        if (!preValuesDict.ContainsKey("docTypeGuid") || !Guid.TryParse(preValuesDict["docTypeGuid"], out contentTypeGuid))
            return null;

        var contentTypeAlias = GetContentTypeAliasByGuid(Guid.Parse(preValuesDict["docTypeGuid"]));
        return ApplicationContext.Current.Services.ContentTypeService.GetContentType(contentTypeAlias);
    }

preValuesDict不包含'docTypeGuid'，它包含这些属性

{[contentTypes, [ {"ncAlias": "eventCategoryList", "ncTabAlias": "Event Category List", "nameTemplate": "" }]]} System.Collections.Generic.KeyValuePair<string, string>
{[minItems, 1]} System.Collections.Generic.KeyValuePair<string, string>
{[maxItems, 10]}    System.Collections.Generic.KeyValuePair<string, string>
{[confirmDeletes, 1]}   System.Collections.Generic.KeyValuePair<string, string>
{[showIcons, 1]}    System.Collections.Generic.KeyValuePair<string, string>
{[hideLabel, ]} System.Collections.Generic.KeyValuePair<string, string>

我想也许我将错误的属性传递给NestedContentCreator.GenerateNestedContentValue但不知道我应该传递什么。

我已经通过不使用Gist - https://gist.github.com/robertjf/c6d9122d90b4406b19ec来解决这个问题。

相反，我使用了来自此处的信息 - https://github.com/umco/umbraco-nested-content/issues/57

生成此代码

        foreach (Dictionary<string, object> category in categories)
        {
            dynamic ncItem = new ExpandoObject();

            var locaUdi = Udi.Create(Constants.UdiEntityType.Document, ((Umbraco.Core.Models.Content)category["eventCategory"]).Key);

            ((IDictionary<string, object>)ncItem).Add("name", "Some item name");
            ((IDictionary<string, object>)ncItem).Add("ncContentTypeAlias", "eventCategoryList");
            ((IDictionary<string, object>)ncItem).Add("eventCategory", locaUdi);

            ncItems.Add(ncItem);
        }

getCategory是

    private Dictionary<string, object> getCategory(string v)
    {
        var eventCategoryRoot = Services.ContentService.GetById(EventCategoryRootGuid);
        var categoryGuid = Services.ContentService.GetChildren(eventCategoryRoot.Id).Where(c => c.Name == v).FirstOrDefault();

        if (categoryGuid == null)
        {
            return null;
        }

        var category = new Dictionary<string, object>();
        category.Add("eventCategory", categoryGuid);

        return category;
    }

在API控制器中创建NestedContent-ContentPicker项
