Orchard CMS一個ContentPart在多個視圖上

Question

現有模型-\\ Models \\ HeaderPart.cs。 在驅動程序中，要創建CategoriesMenuDriver並使用HeaderPart：

  public class CategoriesMenuDriver : ContentPartDriver<HeaderPart>
    {
    private readonly dynamic shapeFactory;
    private readonly IMenuAccessor menuAccessor;

    public CategoriesMenuDriver(
          IShapeFactory shapeFactory,
          IMenuAccessor menuAccessor)
      {
        this.shapeFactory = shapeFactory;
        this.menuAccessor = menuAccessor;
    }

    protected override DriverResult Display(HeaderPart part, string displayType, dynamic shapeHelper)
        {
          return this.ContentShape("Parts_CategoriesMenu", () => shapeHelper.Parts_CategoriesMenu(
            MenuItems: this.menuAccessor.GetMenu<NavigationMenuItem>("UserAccount")));
        }
    }

但是在CategoriesMenu視圖中

  var headerPart = (HeaderPart)Model.ContentItem.HeaderPart;

Model.ContentItem為null。

我可以在View CategoriesMenu中獲得HeaderPart嗎？

您應該能夠像這樣訪問零件：

HeaderPart part = Model.ContentPart;

盡管Model.ContentItem不應為null，這很奇怪

編輯如果它也為null，則可以嘗試自己進行設置：

protected override DriverResult Display(HeaderPart part, string displayType, dynamic shapeHelper)
{
        return ContentShape("Parts_CategoriesMenu", () => shapeHelper.Parts_CategoriesMenu(
            MenuItems: this.menuAccessor.GetMenu<NavigationMenuItem>("UserAccount"),
            ContentPart: part       
        ));
    }
}
