Forum rights management

There are few entities that we should focus on when we are talking about rights in the Forum application: forum, topic, answer and comment.
By default, any regular user is allowed to perform the same actions on all the above mentioned entities, just as they are on any other wiki page: create a new one, edit any(even created by others), delete only those for which is the creator.
In order to be able to properly configure a rights schema on Forum application, please read and understand the XWiki Access Rights Guide.
Since the default behavior often needs to be modified to meet the requirements, the following sections represent some general use cases and the solutions that address them:

Allow only certain users to create a forum

In order to allow only certain users to create a forum, two actions have to be done, by an user with admin rights (using, in each case, the menu > Administer page > Rights: Page & Children):

  • from Forums.WebHome page -> explicitly allow edit rights only for the needed users or groups of users (this will prevent all the other users to create, edit, delete).
  • from each Forum page -> explicitly allow edit rights for XWikiAllGroup (this will resume the unwanted behavior from the previous action).

This is a simple rights schema achievable when there are no other rights constraints on the Forum application. Things get complicated, otherwise.

Close a forum, topic or answer

An entity can be closed when is considered to be at end of live and the activity on it should stop. Nothing can be created, edited or deleted.
A closed forum implies that all the topics and answers are closed.
A closed topic implies that all the answers are closed.
When an entity needs to be closed, an user with Admin rights can deny edit and comment rights for all the users by explicitly allowing the edit and comment rights to some Admin/Moderator users or groups (using, in each case, the menu > Administer page > Rights: Page & Children).

Delete a forum, topic or answer

Deletion can be performed, by default, only by Admin users. It will also work when in the forum is only one participant (the creator).
By default Forums, Topics and Answers can be deleted only by their creators and Admin users. However, an user can't delete a forum if is not allowed to delete all the topics children and their answers children.
Deleting a forum means that all its topics and answers are being deleted.
Deleting a topic means that all its answers are being deleted.
A forum creator must be explicitly allowed to delete a forum, in order to be able to delete the topics and answers (using the menu > Administer page > Rights: Page & Children). The same applies when a topic creator wants to delete a topic. An answer can be deleted by its creator without any constraint.
