#add_to_hook(hook, block) ⇒ Object

def add_to_hook(hook, block)
  # get existing hook calls
  hook_calls = instance_variable_get(:"@hook_calls")
  # add new one for the appropriate hook
  if hook_calls[hook].is_a?(Array)
    hook_calls[hook] << block
  else
    hook_calls[hook] = [block]
  end
  instance_variable_set(:"@hook_calls",hook_calls)
end

#setup_hooks! ⇒ Object

A method to call the hooks. This iterates over each of the types of hook (:after_find, :before_save etc, identified here: github.com/remiprev/her#callbacks) and sets up the actual hook. All this is worth it to control order.
