SID-02278: Display Members of a Group

Status: Answered Answered TWiki version: 6.0.1 Perl version:
Category: CategoryAccessControl Server OS: Last update: 10 months ago

Is there a way to display the usernames of all members of a group if the parent group contains nested groups?

%SEARCH{ "Set GROUP =" web="Main" topic="TWikiAdminGroup" nosearch="on" nototal="on" multiple="on" format="$percntCALC{$SET(list, $pattern(.*\= *([^\n]*).*)) $GET(list) }$percnt" }%

The above works if the group contains ONLY individual users however if the group contains other groups the output returns the group name.

If this doesn't exist would a good strategy be to modify the GROUPS variable be modified to allow for an individual group name to be entered as a parameter?

Discussion and Answer

I agree with the enhancement to GROUPS to limit output to a single group.

By the way: There is (there always seems to be) a way to leverage the GROUPS variable to do what you want:

  1. Use GROUPS to populate a SpreadSheetPlugin-hash mapping group names to group members
  2. Use $GETHASH to retrieve a single group.

%GROUPS{header="" format="$percntCALC{$SETHASH(groups,$group,$members)}$percnt"}%
Members of !TopLevelGroup: %CALC{$GETHASH(groups,TopLevelGroup)}%
Other formats of the user list can be achieved by mangling the GETHASH result through the amazing functions of the SpreadSheetPlugin. Get a sorted bullet list like this (note there are exactly three spaces before CALC to get the first entry right):
   %CALC{$LISTJOIN($n$sp$sp$sp,$LISTEACH($index $item,$LISTSORT($GETHASH(groups,TopLevelGroup))))}%

Brilliant! Thank you Harald!

I've submitted this as a Feature Proposal as well - GroupsAdditionalFunctionality.

For anyone else coming across this support request I've added the info below if you want to use the results of the hash as Main.Harald posted above as values in a form.

I believe that the $SETHASH must be provided for each formfield value.

For example, a topic defining a form:

---+ %TOPIC%

| *Name* | *Type* | *Size* | *Values* | *Tooltip message* | *Attributes* |
| PaintReviewers | checkbox | 5 | %CALCULATE{%GROUPS{header="none" format="$SETHASH(groups,$group,$members)" memberformat="$wikiname" separator=""}%$GETHASH(groups, PaintReviewerGroup)}%| | |
| PaintApprovers | checkbox | 5 | %CALCULATE{%GROUPS{header="none" format="$SETHASH(groups,$group,$members)" memberformat="$wikiname" separator=""}%$GETHASH(groups, PaintApproverGroup)}% | | |

If the hash is defined outside of the Values column of the form table the HASH itself is not defined and the result is no options in your form.

%EDITFORMFIELD{"PaintReviewer" topic="%TOPIC%"}%

An alternative is defining the hash ($SETHASH) in each topic that the form is used however I believe this is a better way.
