History: Permission Management

            A profile would not be very useful if it could not grant rights appropriately for groups. Profiles allow to create groups and to modify the permissions of existing groups using a unified syntax.

The permissions block is a top level block.

For category permissions: create the categories and assign items to them with the ((category handler)). Then give groups permissions on the categories with the permissions handler.
! Example

!! Group Permissions Example
{CODE(caption=>YAML,wrap=>1)}
permissions:
 Anonymous:
  allow: [ export_wiki ]
 Registered:
  description: Users that are logged in
  allow: [ edit, minor ]
  deny: [ export_wiki ]
 Moderators:
  description: Trusted users watching the recent changes to avoid spam
  allow: [ rollback ]
  include: [ Registered ]
{CODE}



!! Group Permissions and Object Permissions Example
{CODE(caption=>YAML,wrap=>1)}
permissions:
 Anonymous:
  allow: [ export_wiki ]
 Registered:
  description: Users that are logged in
  allow: [ edit, minor ]
  deny: [ export_wiki ]
 Moderators:
  description: Trusted users watching the recent changes to avoid spam
  allow: [ rollback ]
  include: [ Registered ]
  objects:
   -
    type: forum
    id: $moderator_discussion_forum
    allow: [ forum_post, forum_post_topic, forum_read ]
{CODE}

!! Dynamic group name examples
The dynamic groups are useful when ((Data Channels)) are used to set-up workspaces. Based on user input or object reference, a dynamic group name can be created and used instead of the simple group name.

{CODE(caption=>YAML,wrap=>1)}
mappings:
 Member: Member ($profileobject:some_ref$)
 Leader: Leader ($profileobject:some_ref$)
permissions:
 Member:
  allow: [ view, edit ]
 Leader:
  allow: [ view, edit, rollback ]
{CODE}
In the above example, the group respectively named 'Member (ref)' and 'Leader (ref)' will be created if they did not exist (if ref is the input you give in the form)

Permissions can be set to specific objects as long as the ID is known or it was also created by a profile using ((Object References)). The object type does not have to be supported by Tiki Profiles, but a static ID will have to be provided.

!!! Create a group from user input
The example below uses two $profilerequest inputs, one for group name and one for description.

''Note: if you have underscore characters in your reference names it will not work (here __groupname__ is good, __group_name__ is not).''

{CODE(caption=YAML wrap=1)} 

mappings:
 DummyGroupName: $profilerequest:groupname$Default name$

permissions:
 DummyGroupName:
  description: $profilerequest:groupdesc$Default description$
  include: [ Registered ]
  allow: [ search, view_category, wiki_view_attachments, view ]

{CODE}

! Group attributes
Unless mentioned otherwise, these attributes only apply on group creation
||__Field name__|__Mandatory__|__Value__
