Viewdata in Application.spark

[xteron]

Hello,

I have written this in the mode/menu.cs file:

IQueryable<MenuItem> ViewMenu()
{
return from ost in db.MenuItems
orderby ost.SortID
select ost;
}


I want to use this in the application.spark file to view the menu on
all pages? What is the best way to do that?

I'm not sure of the best way. But the way I might use would be to
(using .Net 3.5):

1) Make a MenuItemViewMode.cs with needed properties like Text and
Link (or just use your MenuItem if just a DTO).
2) Add a BuildMenuList.cs filter that in OnActionExecuting does your
query, maps each MenuItem to MenuItemViewModel, and sets
filterContext.Controller.ViewData["MenuItems"] =
IEnumerable<MenuItemViewModel>.
3) Put this filter on the Controller(s) as an attribute
[BuildMenuList].
4) Add a partial view <MenuItems/> to the master layout in
application.spark.
5) Have _MenuItems.spark use <li each='var item in
ViewData["MenuItems"]'><a href="!{item.Link}">${item.Text}</a></li>.

The best way would probably not use a filter, add the list to a
strongly typed model, and do some caching.

I have not used IQueryable, but I know IEnumerable or IList will work.  You just add a viewdata tag to the top of the view as such:

<viewdata model='IList[[MenuItem]]' />

you can then access the model property as in webforms view engine.  There is much more documentation on it at the spark website.

Hope this helps.

Thank you so much. Will try what you sad and see if I get it to
work. :)
