feat(triggers): declarative time-relative trigger (#1874) - #3230
Merged
Conversation
Time-relative business rules ("alert 60 days before a contract's end_date")
could only be expressed as a record_change flow gated on a date-equality
condition like `end_date == daysFromNow(60)`. That predicate is evaluated only
when the record happens to change, so it fires only if a record is edited on
exactly the threshold day — i.e. almost never, unattended. The robust
alternative was a hand-written cron + range query that every author
re-implemented (contracts renewal_alert, hr document_expiring_soon,
procurement po_overdue, ...).
A flow's start node can now declare a `timeRelative` descriptor:
config: {
timeRelative: {
object: 'contracts',
dateField: 'end_date',
offsetDays: [60, 30, 7], // T-minus reminders — fires on each threshold day
// — or — withinDays: 30 // "expiring soon" range; negative = overdue lookback
filter: { status: 'active' }, // optional, ANDed with the date window
},
schedule: { type: 'cron', expression: '0 8 * * *' }, // optional; default daily 08:00 UTC
}
The new time_relative trigger (TimeRelativeTriggerPlugin, shipped in
@objectstack/trigger-schedule) sweeps the object on that schedule and launches
the flow once per matching record, with the record on the automation context —
so the start-node condition gate and {record.<field>} interpolation work exactly
as for a record-change flow. Because the window is evaluated every day, a
threshold is never missed regardless of when the record last changed.
- spec: new TimeRelativeTriggerSchema (@objectstack/spec/automation), the Zod
source of truth; exactly one of withinDays | offsetDays is required.
- engine: resolveTriggerBinding routes a start node carrying config.timeRelative
to the time_relative trigger, ahead of the plain schedule trigger (whose
behavior is unchanged) since such a flow also carries a schedule cadence.
- trigger: composes the schedule trigger's job service (sweep cadence) with the
ObjectQL engine (date-window query). The discovery query runs as a system
operation (RLS-bypassing), is capped at maxRecords/tick (default 1000), and
isolates per-record failures so one bad row never aborts the sweep.
- lint: os validate gains readiness checks for the new descriptor (unknown swept
object, ambiguous draft status).
- cli: serve.ts arms the plugin in the triggers group.

Adds the declarative time-relative trigger to the two hand-written author-facing surfaces: skills/objectstack-automation/SKILL.md (a Time-relative triggers section, framed as the replacement for the date-equality-on-record-change anti-pattern) and content/docs/automation/flows.mdx (a Time-relative flow example). The auto-generated reference and package README landed with the feature (#3230).

… 进入 v17 (objectstack-ai#4732) * chore: bump objectui to 785b8a5d432c fix(fields)!: FieldWidgetComponentProps stops claiming to have every key (objectstack-ai#3221) (objectstack-ai#3230) objectui@785b8a5d432cf009389a1a9180fdac2a8297543f * docs(changeset): carry the objectui batch's authoring semantics into the pin changeset The auto-generated pin changeset lists commit subjects only, so the one author-BREAKING change in the range (objectui#3203 — `ActionParam` loses the nine resolved-only picker keys) would have reached the release notes as a one-line Chinese subject with no migration and no rationale. Spell out the FROM/TO prescription and why the removal is not a regression (the keys were never storable: `ActionParamSchema` is `.strict()` and its alias table names `referenceto -> reference`), plus the author-visible halves of objectui#3196 / objectstack-ai#3204 / objectstack-ai#3210. Also drops the two `fix(ci)` lines from the enumerated range: they release nothing and are not in the shipped bundle, so listing them as "frontend changes" overstates what the artifact carries.
