Manual:User groups table/pl

Tabela user_groups łączy użytkowników z przypisanymi im grupami uprawnień. Each group can be assigned a mixture of permissions through or via extensions; all users of a particular group have those permissions granted to them as a result of their membership in the group. As the table is separate from the table, this allows for the creation of a shared user database with permissions that vary from wiki to wiki within a wiki farm. This table was introduced on r5648, in MediaWiki 1.5. If you are using MediaWiki 1.3 or 1.4, have a look at. Before MediaWiki 1.5, user rights were stored in the field of the  table.

All unregistered users automatically belong to the  group and only to that group; all registered users additionally are automatically part of the   group. User groups are additive; as a result, all registered users have all the privileges assigned to the  group as well. Formerly there was a "sysop bit"; now, making a user a sysop adds a row to.

ug_user
This field links to a given user's. It is a foreign key used to link accounts with their assigned privileges.

ug_group
This field stores the user's permissions, which are stored as groups. At runtime, will associate group keys with particular permissions; a user will have the combined permissions of any group they're explicitly in, plus the implicit   and   groups. Example  values: 'bot', 'bureaucrat', 'sysop'.

There is one row for each (explicit) group the user is in.

ug_expiry
This field stores a user group's expiry time. It is similar to pr_expiry in the page restrictions table and ipb_expiry in the ipblocks table.
