I am trying to get all the folders items inside of a list. I know that folder content types start with 0x0120. So I wrote these two queries
http://sharepoint.com/sites/dev3/_api/web/lists/getbytitle('Discussions')/items?$filter=substringof(%270x0120%27,ContentTypeId)
This returns no results.
(this was a solution recommended in this thread OData substringof or startswith returning all items)
I also tried
http://sharepoint.com/sites/dev3/_api/web/lists/getbytitle('Discussions')/items?$startswith(%270x0120%27,ContentTypeId)
This returns results but it returns everything ... it does not really do the filtering based on the ID specified by me.
i also tried
http://sharepoint.com/sites/dev3/_api/web/GetFolderByServerRelativeUrl('/sites/dev3/lists/Discussions')/folders
This gives results... but does not return details like the Item Id which I need.
My end object is that if there is a list which has a folder called Foo and an Item called Bar. the query should fetch only the Foo folder and give me details like the etc.
I am looking for a REST solution (no CAML). so far the soltuions which I have tried either return everything Foo and Bar. or nothing.
