Manuel:Contenu Schéma de base de données MédiaWiki table user_former_groups
Version de MediaWiki :
1.18

The user_former_groups table stores the groups the user has once belonged to (will not contain groups the user had belonged to before MW 1.17). The user may again belong to these groups; check the table user_groups , if you want to know. This is used to keep MediaWiki from automatically adding users to groups from which they have been manually removed before. The table was added in r90749.

Fields

ufg_user

Key to user_id .

ufg_group

Name of the group, which the user was member of.
