Split the list view code up in three pieces 1. getListContents which returns the required contents dictionary 2. _list which returns the response for a specified list of contents 3. list which constructs just one content dict and passes it to _list This way it is easier to do step 1 and 2 in other code than list(), which makes it possible to display multiple list pages (by calling getListContents multiple times and passing the result to _list).
