Overview

An action is a group of changes to a single card that is recorded during an act. Together, acts, actions, and changes comprise a comprehensive card history tracking system.

For example, if a given web submission changes both the name and type of a given card, that would be recorded as one action with two changes. If there are multiple cards changed, each card would have its own action, but the whole submission would still comprise just one single act.

An Action records:

  • the card_id of the card acted upon

  • the card_act_id of the act of which the action is part

  • the action_type (create, update, or delete)

  • a boolean indicated whether the action is a draft

  • a comment (where applicable)
