Class Method Details

.fetch_sfx_urls ⇒ Object

Atttempts to extract all URLs that SFX knows about from the db. This process is not 100%, becuase of the way SFX calculates URLs on the fly. We are only grabbing them from the db–and even the way they are stored in the db is hard for us to grab reliably! So this is really just a kind of guess heuristic in a bunch of ways. But we do our best, and use this to load the SfxUrl model.
