Q: 

Select all users that have a particular role (where users and roles are many-to-many)

My users have and belong to many roles, and likewise my roles have and belong to many users.

How can I select all users who have the role "editor"? How can I select all users who have only the role "editor"?

+2  A: 

How can I select all users who have the role "editor"? 

Role.find_by_name('editor').users

How can I select all users who have only the role "editor"?
For that, you'll probably have to pass pure sql condition in the 'find' method.
