NO, it isn't right.
If I use this code:
members.select {|m| m.role.assignable?}.collect {|m| m.role}.sort
...I get several roles with the same ID and NAME, but I want to get
unique ones, like using DISTINCT operation in SQL statements (SELECT
DISTINCT name FROM roles.....)
But unfortunately I can get the list from table "members", where records
may have several same role names:
Manager
Tester
Manager
Manager
Manager
Tester
Developer
Developer
Tester
Developer
Tester
Developer
Developer
Developer
But I have to get this list:
Manager
Tester
Developer
