Feed

Inherits Ktistec::Model::Common < Ktistec::Model < Reference < Object

An algorithmic feed.

A feed is a runtime-created sibling collection to the timeline whose membership is decided by a judge rather than by a fixed structural rule. The judge's verdicts are the base facts a generic materialized view queries.

Constants

HORIZON = 30.days

How far back a newly published feed reaches.

Class methods

Source

feed_type

The relationship type of the feed's materialized rows.

nil means "no backfill".

Source

floor=(floor : Time | Nil)
