Question

我无法找到有关如何针对信息集部分执行HQLQuery的任何示例。我正在构建自定义日历/事件管理模块，需要查询即将发生的事件。我使用严格的信息集（没有EventPartRecord类），但我似乎无法正确查询。

每个日历可以显示多个事件类别，每个事件也可以显示多个事件类别。

以下代码产生代码后发布的错误：

    public IEnumerable<EventPart> GetUpcomingEventsForCalendar(CalendarPart calendar, 
        VersionOptions versionOptions, int count)
    {
        versionOptions = versionOptions ?? VersionOptions.Published;

        string[] ids = calendar.EventCategoryIds;

        var events = _contentManager.HqlQuery()
            .ForPart<EventPart>()
            .Where(alias => alias.ContentItem() ,a=>
                a.And(x => x.Ge("StartDate", DateTime.Today), y => y.InG("EventCategoryIds", ids)))
            .OrderBy(x => x.ContentItem(), order => order.Asc("StartDate"))
            .Slice(0, count);

        return events;
    }

错误：

Orchard.ContentManagement.Drivers.Coordinators.ContentPartDriverCoordinator: 
ERROR - QueryException thrown from IContentPartDriver by

NHibernate.QueryException: could not resolve property: StartDate of:

Answer 1

您无法查询仅保留在InfosetPart内的属性。如果您需要查询某个零件的某些属性，则需要有一个包含这些属性的支持记录 - 经典方式。
