def refresh_render_caches
  # TODO: inefficient, but Model.each breaks Sequel in validation
  # "commands out of sync"
  all.each do |record|
    # Mark all caching columns as changed, so the before_save hook
    # processes them.
    record.skip_timestamp_update = true
    render_fields.keys.each do |column|

#render(field, params = {}) ⇒ Object

Assigns a field to cache

render :body, :with => ‘wikify’, :to => ‘cached_body’

… calls #wikify on the value of self.body, and stores the result in self.cached_body. :to defaults to the field name with _cache appended. :with defaults to :render.
