为什么我的Umbraco根页面仅在当前活动页面时没有子级？
[英]Why does my root Umbraco page have no Children only when it is the currently active page?
问题描述
I have the following page structure in Umbraco:
我在Umbraco中具有以下页面结构：
- Home
- Device Management
- Resources
- Manuals
- Downloads
- Terms & Conditions
I have a navigation menu as a partial in my Master.cshtml template which is the base template of all of these pages.
Model.Content.Site().Childrento get all the "Device Management" and "Resources" nodes then recurse to get any descendant nodes of these.Model.Content.Site().Children来获取所有的“设备管理”和“资源”节点，然后递归以获取这些节点的任何后代节点。This all worked fine when all of the pages used the same Document Type (
ChildNodeSelectionPage) but now I've changed the Home page to use a derived form of this document type (CustomChildNodeSelectionPage) for an additional property and had to create a dummy controller (CustomChildNodeSelectionPageController) in my project which derives from the originalChildNodeSelectionPageControllerso that theMastermodel still gets passed back to the view.ChildNodeSelectionPage）时，这一切都很好，但是现在我已更改主页，以使用此文档类型的派生形式（CustomChildNodeSelectionPage）作为附加属性，并且不得不创建一个虚拟控制器（我的项目中的CustomChildNodeSelectionPageController）是从原始ChildNodeSelectionPageController派生的，因此Master模型仍然可以传递回视图。This part also seems to work fine (based upon breakpoints being hit in the original controller) but the problem happens when the view is hit: now, for some unknown reason,
Model.Content.Site().Childrenhas a count of 0 when on the Home page but yet, if navigating to the URL of any of the child pages it's 2 (as expected).Model.Content.Site().Children的计数为0在首页上，但是，如果导航到任何子页面的URL，则为2（按预期）。Also note that the Home Document still uses the
ChildNodeSelectionPage.cshtmlTemplate even though its Document Type has now been changed to use "Custom Child Node Selection Page").ChildNodeSelectionPage.cshtml模板。Master.cshtml (note: irrelevant code omitted for brevity)
@inherits Umbraco.Web.Mvc.UmbracoViewPage<Web.Portal.Models.Master> <!DOCTYPE html> <html> <body> @Html.Partial("Navigation Menu") @RenderBody() </body> </html>Navigation Menu.cshtml
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage @using Umbraco.Web @using Umbraco.Web.Models @helper AddMenuItems(IEnumerable<IPublishedContent> menuItems) { if (menuItems.Any()) { <ul> @foreach (var menuItem in menuItems) { <li> @if (menuItem.Id == UmbracoContext.PageId) { @menuItem.Name } else { <a href="@menuItem.Url" title="@menuItem.GetPropertyValue("description")">@menuItem.Name</a> } @AddMenuItems(menuItem.Children) </li> } </ul> } } //NOTE: This is where the problem is when called from the `CustomChildNodeSelectionPage`. @AddMenuItems(Model.Content.Site().Children)ChildNodeSelectionPage.cshtml
@inherits Umbraco.Web.Mvc.UmbracoTemplatePage @{ Layout = "Shared/Master.cshtml"; } //NOTE: Irrelevant code omitted for brevity.ChildNodeSelectionPageController
public class ChildNodeSelectionPageController : RenderMvcController { private ActionResult Index(IPublishedContent content, CultureInfo currentCulture) => CurrentTemplate ( new Master ( content, currentCulture, new Company(0, "ACME"), new[] { new Company(0, "ACME"), new Company(1, "Jimbo Jones' Jimbo Burgers Inc.") }, "Jiminy Jilikers" ) ); public override ActionResult Index(RenderModel model) => Index ( model.Content, model.CurrentCulture ); }CustomChildNodeSelectionPageController
//Exists only so that the new Document Type can call Index on ChildNOdeSelectionPageController. public class CustomChildNodeSelectionPageController : ChildNodeSelectionPageController { }

So it turns out all I had to do was manually republish ("Save and Publish" button on "Content") every page through the CMS and it magically started working again! 因此，事实证明，我要做的就是通过CMS在每个页面上手动重新发布（“内容”上的“保存并发布”按钮），并且神奇地再次开始工作！ Prior to this issue, I did have to change the Content Type of the root page via the database which seemed to create a few problems (of which I'm guessing this was one of them). 在此问题之前，我确实必须通过数据库更改根页面的内容类型，这似乎会产生一些问题（我猜这是其中的一个）。
If anyone's interested, I got the idea to republish from here: https://our.umbraco.com/forum/templating/templates-and-document-types/4585-Change-document-type 如果有人感兴趣，我有个主意可以从此处重新发布： https : //our.umbraco.com/forum/templating/templates-and-document-types/4585-Change-document-type
