RailsAdmin is a Rails engine that provides an easy-to-use interface for managing your data

Project#validate_board_limit

Similar to the normal callbacks that hook into the life cycle of an
Active Record object, you can also define callbacks that get triggered
when you add an object to an association collection. If any of these
callbacks throw an exception, the object will not be added to the
collection. Before you add a new board to the boards collection if you
already have 1, 2, or n it will fail, but it if you have 0 that is lower
than the number of permitted boards per project it won't fail.
