Question

This is the first time I have experimented with the awesome Web Api and Backbone. So far everything seems like a match made in heaven. However I cant seem to return the relevant data using the OData filters. For Example I have the following as an action method:

    //GET /api/posts/
    public IQueryable<KiaFamilyPost> Get()
    {
        return _db.Posts
            .Include("Badge")
            .Include("Entry")
            .AsQueryable();
    }

Now I would like to filter the above posts, and return them in descending order. From my understanding I could do the following “http://[MySite]/api/posts?$filter=id eq 2&$orderby=DatePost desc”. I am trying to do the following to no avail:

        APP.posts_collection.fetch({data: {
            entryId: APP.entry.get('Id'),
            $order: 'Id desc'
        }});

Backbone makes the following call to the controller “http://[MySite]/api/posts?entryId=1&%24order=Id+desc”. Anyone been able to get this to work correctly?

Thanks

I experimented with a plugin from Addy Osmani called backbone.paginator. If you are working with a Web Api like MVC 4, I believe this will be a great fit. All you do is extend your collection with a handful of parameters provided by the Paginator. Eg.

    perPageAttribute: '$top',

    skipAttribute: '$skip',

    orderAttribute: 'orderBy',

    customAttribute1: '$inlinecount',

    queryAttribute: '$filter',

    formatAttribute: '$format',

    customAttribute2: '$callback',`
