Class Method Details

.find_or_create!(name, known_groups = nil) ⇒ Object

Finds a group by name, creating it if it doesn’t exist

If known_groups is provided, it will be used as a cache to reduce the number of database lookups needed.

This uses Lock#synchronize internally, so it probably should not be called within a transaction block.
