Grouper Users - Open Discussion List

[Chris Hyzer <>]

Yes, that is what the classlist at penn and the joins to the grouper_groups table does...  obviously I need to revist that doc, its hard to understand.

 

I wrote this up earlier this year with a long discussion on the list:

Now you need to flex your SQL muscles and make a query that will create all the other groups for you (use UNION?). Or this could be multiple loader jobs.   This is in a separate loader job that runs after (?) the first one. You can join to the grouper groups table so that it only does groups that exist and wont have unresolvable subject errors. Note if you join to the grouper_groups table, the you will get better performance too.  However you might want to run this 3 times in a row (or however many times it needs) so that all can be managed in one day.

grouperLoaderQuery:   select group_name, subject_identifier, subject_source_id from course_group_structure_v
GROUP_NAME		SUBJECT_IDENTIFIER	SUBJECT_SOURCE_ID
courses:math101:math101		courses:math101:math101_students	g:gsa
courses:math101:math101		courses:math101:math101_instructors	g:gsa
courses:math101:math101_students		courses:math101:math101_students_includes	g:gsa
courses:math101:math101_students		courses:math101:math101_students_systemOfRecord	g:gsa
courses:math101:math101_instructors		courses:math101:math101_instructors_includes	g:gsa
courses:math101:math101_instructors		courses:math101:math101_instructors_systemOfRecord	g:gsa
courses:english101:english101		courses:english101:english101_students	g:gsa
courses:english101:english101		courses:english101:engilsh101_instructors	g:gsa

Now we can have privileges on these groups... again, you can do this with views, and unions, etc  Note, if you can join to the grouper_groups table and use the group UUIDs, it would be faster.

grouperLoaderGroupQuery: select group_name, readers, updaters from course_group_query_v
GROUP_NAME		READERS	UPDATERS
courses:math101:math101		courses:etc:courseReaders,courses:math101:math101_instructors
courses:math101:math101_students		courses:etc:courseReaders,courses:math101:math101_instructors
courses:math101:math101_students_includes		courses:etc:courseReaders,courses:math101:math101_instructors	courses:etc:courseUpdaters,courses:math101:math101_instructors
courses:math101:math101_instructors		courses:etc:courseReaders,courses:math101:math101_instructors
courses:math101:math101_instructors_includes		courses:etc:courseReaders,courses:math101:math101_instructors	courses:etc:courseUpdaters,courses:math101:math101_instructors
courses:english101:english101		courses:etc:courseReaders,courses:english101:english101_instructors

Subject: [grouper-users] roll ups using the loader?

 

Hi,

 

Outside of the addIncludeExclude functionality is it possible for a

loader job to manage arbitrary "roll ups" of groups like 'students',

'instructors', and 'guests' into an 'all' group?

 

Thanks,

 

Scott K
