Class Method Details

.domains ⇒ Object

A backfill domain is an opaque selector for backfills and their client resources to coordinate with. Use them to partition backfills by the stability of interface, or to group like resources or whatever. Backfill domain names will never be exposed outside of the server.

def self.fragment_for(name, type)
  "##{name}-#{type}"
end

.types ⇒ Object

Backfill types are used to select within a resource which backfill is being rendered - the defaults are :update and :create to correspond with PUT and POST methods and af:Update and af:Create.
