問題：
I am wondering if there is a way (similar to Gmail) for AngularJS to delay showing a new route until after each model and its data has been fetched using its respective services. 我想知道AngularJS是否有一種方法（類似於Gmail） 延遲顯示新路由，直到每個模型及其數據已使用其各自的服務獲取 。
For example, if there were a ProjectsController that listed all Projects and project_index.html which was the template that showed these Projects, Project.query() would be fetched completely before showing the new page. 例如，如果有一個ProjectsController列出了所有Projects和project_index.html ，它們是顯示這些Projects的模板， Project.query()將在顯示新頁面之前完全獲取。
Until then, the old page would still continue to show (for example, if I were browsing another page and then decided to see this Project index). 在此之前，舊頁面仍將繼續顯示（例如，如果我正在瀏覽另一個頁面，然後決定查看此項目索引）。
