Function revise 

Source 
pub async fn revise(
    pool: &PgPool,
    actor: &Actor,
    id: Uuid,
) -> AppResult<Revision>
Expand description

Creates the next revision of an item, copying attributes, files and BOM lines from revision id. Only possible when the item has no open revision.

§Invariants

  • Permission: CAD editor; the source revision is visible (“not found” otherwise) and in a group the actor may edit (403); the item has no revision in work or in review (409).
  • Locks: the source revision row (revisions::lock), then the item row (FOR UPDATE), which serialises concurrent revisions of the same item.
  • Audit: revision.revise.
  • Notifications: the watchers of the item.
  • Webhooks: none.
  • Data: the new revision is checked out by the actor and takes over attributes, files (as version 1), references, simulations and BOM lines.
  • Atomic: one transaction.
