Overview

The WikiController follows the Rails REST controller pattern but with a few differences

  • index - shows a list of WikiPages grouped by page or date

  • new - not used

  • create - not used

  • show - will also show the form for creating a new wiki page

  • edit - used to edit an existing or new page

  • update - used to save a wiki page update to the database, including new pages

  • destroy - normal

Other member and collection methods are also used
