Question

我在Umbraco 6.1.5上使用uBlogsy WebForms 3.0.2 ...

目标网页上的帖子没有显示。

函数PostService.Instance.GetPosts返回0个帖子，即使帖子位于正确的位置。

当我尝试替换它时，我仍然会得到0个帖子：

var posts = PostService.Instance
                       .GetPosts(
                           IPublishedContentHelper.GetNode((int)Model.Id)
                       ).ToIPublishedContent(true);
int postCount = posts.Count();

有谁知道为什么邮政服务不起作用？或者，发生了什么？

我和Ublogsy有过同样的问题。所以我决定编写自己的代码如下：

（有点长）

// get tag, label, or author from query string
    var tag = Request.QueryString["tag"] ?? "";
    var label = Request.QueryString["label"] ?? "";
    var author = Request.QueryString["author"] ?? "";
    var searchTerm = Request.QueryString["search"] ?? "";
    var commenter = Request.QueryString["commenter"] ?? "";
    int page = int.TryParse(Request.QueryString["page"], out page) ? page : 1;
    var year = Request.QueryString["year"] ?? "";
    var month = Request.QueryString["month"] ?? "";
    var day = Request.QueryString["day"] ?? "";
    int postCount;

IEnumerable<IPublishedContent> posts = new BlockingCollection<IPublishedContent>();

var filterResults = this.FilterAgainstPosts(this.Model.Content, tag, label, author, searchTerm, commenter, year, month);
    if (filterResults != null)
    {
        posts = Enumerable.Take(filterResults.Skip((page - 1) * itemsPerPage), itemsPerPage);
    }

@RenderForLanding(posts)

我的FilterAgainstPosts方法如下：

@functions
{
private IEnumerable<IPublishedContent> FilterAgainstPosts(IPublishedContent landing, string tag, string label, string author, string searchTerm, string commenter, string year, string month)
    {
        IEnumerable<IPublishedContent> filteredPosts = landing.DescendantsOrSelf("uBlogsyPost").Where(x => x.GetProperty("umbracoNaviHide").Value.ToString() != "1");

        if (!String.IsNullOrEmpty(searchTerm))
        {
            filteredPosts = filteredPosts.ForEach(i => this.FilterAgainstTerm(i, searchTerm));
        }

        if (!String.IsNullOrEmpty(tag))
        {
            filteredPosts = filteredPosts.ForEach(i => this.FilterUponTag(i, i.GetProperty("uBlogsyPostTags").Value.ToString(), tag));
        }

        if (!String.IsNullOrEmpty(label))
        {
            filteredPosts = filteredPosts.ForEach(i => this.FilterUponLabel(i, i.GetProperty("uBlogsyPostLabels").Value.ToString(), label));
        }

        if (!String.IsNullOrEmpty(author))
        {
            filteredPosts = filteredPosts.ForEach(i => this.FilterUponAuthor(i, i.GetProperty("uBlogsyPostAuthor").Value.ToString(), author));
        }

        //
        //TODO: Coomenter search needs to added
        //

        if (!string.IsNullOrEmpty(year))
        {
            filteredPosts = filteredPosts.ForEach(i => this.FilterUponYear(i, i.GetProperty("uBlogsyPostDate").Value.ToString(), year));
        }

        if (!string.IsNullOrEmpty(month))
        {
            filteredPosts = filteredPosts.ForEach(i => this.FilterUponMonth(i, i.GetProperty("uBlogsyPostDate").Value.ToString(), month));
