Item5771: Provide a mechanism to clear votes

Being as the votes are stored in a hidden db, it would be useful to provide a mechanism to clear out votes for a particular vote id. Obviously, this would require incorporation of access controls.

Propose this:

Resetting a Poll

Sometimes you want to be able to clear the results of a poll. You can do this by including the %RESETVOTE{"id"}%. If a user is authorised, then a button will be generated which, when clicked, will reset the results for that poll to initial conditions. Access to this feature is controlled using the CANRESETVOTES TWiki variable. This variable defines a list of wiki names and the id's of votes they are allowed to reset. You can use * as a wildcard in the vote IDs. For example, in a WebPreferences topic you can write

   * Set CANRESETVOTES = GeorgeWBush(*),RobertMugabe(zim),SimonCowell(*Idol, XFactor)
   * Set FINALPREFERENCES = CANRESETVOTES

to allow:

• George W. Bush to reset any vote he likes,
• Robert Mugabe to reset the results of any vote with the id zim,
• Simon Cowell to reset the results of all votes with an ID ending in Idol and any vote with the ID XFactor.

Note that it is important to finalise the setting, otherwise it can be overridden in individual topics by anyone with CHANGE access.

Looks good. I can't think of any other way to enable this feature and preserve appropriate permissions.

I did it slightly differently in the end. See the doc.
