Mass assignments protection

Only visible fields are editable in RailsAdmin. Others will get caught and sanitized.

Basically you don't need to protect your attributes in RailsAdmin.

However, :attr_accessible and :attr_protected are taken into account: restricted fields are not editable (read_only). If you whitelist attributes, don't forget to whitelist accessible associations' 'id' methods as well : division_id, player_ids, commentable_type, commentable_id, etc.

:attr_accessible specifies a list of accessible methods for mass-assignment in your ActiveModel models.
