I am getting an error when I create a taxonomy and select the "All Users" checkbox for assignment. I can create, edit, and destroy locations and organizations with any variety of settings set, as soon as the "All Users" box is checked this error is presented when I try to edit the taxonomy. Manually editing the MySQL foreman.taxonomies table and removing User from the ignored_types YAML list lets me go in and work without encountering this bug. The issue looks to be that a query is constructed that references usergroups.admin in the WHERE clause but is only selecting data from the users table.

I am running Foreman and Foreman Proxy on the same host as Puppetmaster. It is RHEL 6.5 x86_64 with the Puppetlabs repo, epel, and remaining packages are installed from RHN.
I am running the Git branch develop (1.5).
I just did a git pull and I believe everything is in working order and fully updated.
I am using MySQL (mysql-server-5.1.73-3.el6_5.x86_64) as a backing database, on another host, it was previously migrated from local PostgreSQL if that matters.

The full stack trace is included below with full stack trace. I can provide logs if needed.

Warning!

Mysql2::Error: Unknown column 'usergroups.admin' in 'where clause': SELECT `users`.`id` FROM `users` WHERE ((users.admin = 0 OR users.admin IS NULL) AND (usergroups.admin = 0 OR usergroups.admin IS NULL))
If you feel this is an error with Foreman itself, please open a new issue with Foreman ticketing system, You would probably need to attach the Full trace and relevant log entries.
