orchardcms - 为什么具有编辑自己的内容权限的用户不能查看具有 EditOwnContent 要求的内容项？

Question

我们有以下代码成功地将菜单项添加到主菜单。

问题是，当我们授予用户编辑自己的内容时，用户看不到这个菜单项。只有我们授予站点所有者权限，用户才能看到它。

那是怎么回事？不应该授予用户编辑自己的内容来解决问题吗？

    {

        public Localizer T { get; set; }

        public DealerDashboardMenuProvider(
            IContentManager contentManager)
        {
            _contentManager = contentManager;
            T = NullLocalizer.Instance;
        }

        public void GetMenu(IContent menu, NavigationBuilder builder)
        {
            builder.Add(T("Dealers"), "2", subMenu => subMenu
                .Url("~/Dealers")
                .Permission(Orchard.Core.Contents.Permissions.EditOwnContent)
                );
        }
    }
