-- Grow journal (#52): time-stamped notes on gardens, beds and plantings.
|
|
--
|
|
-- There is already free-text `notes` on gardens, objects and plants, but it is a
|
|
-- single mutable field: writing "powdery mildew on the west bed" overwrites what
|
|
-- you wrote in June. The distinction worth keeping is that `notes` is WHAT THIS
|
|
-- THING IS, while a journal entry is WHAT HAPPENED, AND WHEN. Both stay.
|
|
--
|
|
-- garden_id is NOT NULL even when the entry is about a bed or a single plop, and
|
|
-- that is the whole trick: permission checks reuse requireGardenRole unchanged
|
|
-- and no new ACL path is invented. object_id/planting_id narrow the target; the
|
|
-- garden always anchors it.
|
|
--
|
|
-- observed_at is deliberately distinct from created_at — you write up Saturday's
|
|
-- observations on Sunday, and the date that matters is Saturday's.
