Orchard CMS ContentManager BuildDisplay 非常慢

Question

我是 Orchard 的新手，但我觉得我正在取得重大进展。我一直致力于使我的显示驱动程序更高效，而构建显示似乎是最需要工作的领域。

当构建显示 30 个内容项时，以下代码大约需要 30 秒才能完成。我不知道还有什么其他方法可以为内容项构建显示形状或使其更快。

非常感谢您的反馈。

var contentItems = _profileService.GetProfileList(profileViewOptionsDetails.filteredServices, pageNumber, profileViewOptionsDetails.PageSize, queryString);
var pager = new Pager(_siteService.GetSiteSettings(), pageNumber, pageSize);
var pagerShape = shapeHelper.Pager(pager).TotalItemCount(totalItemCount);
var list = shapeHelper.List();

foreach (var contentItem in contentItems.ContentItems)
{
    list.Add(_mcrfContentManager.BuildDisplay(contentItem.Content, "Summary"));
}

public FilterGroup GetProfileList(List<int> filterList, int page, int pageSize, string query)
    {
        IList<ProfileRoles> profileRecords = new List<ProfileRoles>();

        FilterGroup filteredProfiles = new FilterGroup();

        profileRecords = GetMcrfProfileList(filterList, query, page, pageSize);

        filteredProfiles.ProfileCount = profileRecords.Count;

        var content = GetMcrfProfileRecords(profileRecords.Select(item => item.ContentID).ToList());

        IList<ProfileListEntity> profileList = new List<ProfileListEntity>();
        foreach (var c in content)
        {
            ProfileListEntity profileListEntity = new ProfileListEntity();
            profileListEntity.Content = c;
            profileListEntity.Role = profileRecords.Where(x => x.ContentID == c.Id).Select(y => y.Role).ToList().First();
                profileList.Add(profileListEntity);
        }
        filteredProfiles.ContentItems = profileList;
        return filteredProfiles;
    }

public IEnumerable<IContent> GetMcrfProfileRecords(IList<int> contentIDs)

如果有多个显示形状，您需要使用 Combined() 包装您的显示形状...并将逻辑放在匿名方法中。

不要使用子句来检查您的 DisplayType，让 placement.info 完成它的工作，一旦您掌握了它，它就会非常强大。

如果您是 Orchard 的新手，我会考虑快速浏览一些文档并下载源代码。通过查看其他零件驱动程序，您将能够了解可以改进什么以及如何改进。
