module Resourceful
module Default
# This module is mostly meant to be used by the make_resourceful default actions.
# It provides various methods that declare where callbacks set in the +make_resourceful+ block,
# like Builder#before and Builder#response_for,
# should be called.
module Callbacks
# Calls any +before+ callbacks set in the +make_resourceful+ block for the given event.
def before(event)
resourceful_fire(:before, event.to_sym)
end
# Calls any +after+ callbacks set in the +make_resourceful+ block for the given event.
def after(event)
resourceful_fire(:after, event.to_sym)
end
# Calls any +response_for+ callbacks set in the +make_resourceful+ block for the given event.
# Note that these aren't called directly,
# but instead passed along to Rails' respond_to method.
def response_for(event)
if responses = self.class.read_inheritable_attribute(:resourceful_responses)[event.to_sym]
respond_to do |format|
responses.each do |key, value|
format.send(key, &scope(value))
end
end
end
end
# Returns a block identical to the given block,
# but in the context of the current controller.
# The returned block accepts no arguments,
# even if the given block accepted them.
