Access logic is not _entirely_ exported from the controller, unfortunately. For interface reasons, some actions which require admin have to be listed within the controller's deny_access method. This is required because, being a default-deny system, cancancan _cannot_ tell you the reason you were denied access; and so the "nice" feedback presenting next steps can't be gleaned from the exception

#
|
|
# user ||= User.new # guest user (not logged in)

# The first argument to `can` is the action you are giving the user
|
|
# permission to do.
|
|
# If you pass :manage it will apply to every action. Other common actions
|
|
# here are :read, :create, :update and :destroy.
|
|
#
|
|
# The second argument is the resource the user can perform the action on.
|
|
# If you pass :all it will apply to every resource. Otherwise pass a Ruby
|
|
# class of the resource.
|
|
#
|
|
# The third argument is an optional hash of conditions to further filter the
|
|
# objects.
|
|
# For example, here the user can only update published articles.
|
|
#
|
|
# can :update, Article, :published => true
