# Create Paddock

`POST /paddocks`

## Request

- Base URL: `https://api.purplegrain.com/api/v1`
- URL: `https://api.purplegrain.com/api/v1/paddocks`
- Auth: HTTP bearer

A name is a valid paddock — everything else arrives later, and the map
lists a paddock with no ring as "by name" rather than as incomplete.

Names are unique per property, case-insensitively, across live AND
archived paddocks: reusing the name of one that was archived is rejected
here, where a name is being typed, rather than stranding the archived
paddock with no way to be restored.

`boundary` is not accepted — the ring is written through
`updatePaddockBoundary`. Requires organization edit rights.

## Query parameters

- `include` string

## Request body

- PaddockCreateModelAttributes: Flat attributes-adapter request body (Content-Type application/json). Attribute fields and relationships live directly under `data` (no nested `attributes` / `relationships` envelopes). Each relationship is a resource identifier object ({ id, type }). Equivalent JSON:API (nested) shape: `PaddockCreateModel` sent as application/vnd.api+json.
  - `data` object, required
    - `name` string, required
    - `area_ha` number, nullable
    - `area_source` 'typed' | 'drawn', nullable
    - `land_use` 'cropping' | 'grazing' | 'mixed' | 'fallow', nullable
    - `current_crop` string, nullable
    - `archived` boolean, nullable
    - `farm` object, nullable, required
      - `id` string, nullable
      - `type` 'farm', nullable

## Response `201`

Created

- PaddocksShowResponseAttributes
  - `data` PaddockModelAttributes: Single paddock in attributes-adapter shape (Accept application/json).
    - `id` string
    - `type` string
    - `slug` string: Unique within its parent (a property per owner; a paddock or mob per property); generated from the name and renamed with it. The old slug keeps resolving. See `resolveLink`.
    - `web_path` string: The address on the web. Present when read directly.
    - `url` string: The whole link; carries the property's `?share=` token when it is shared by link. Present when read directly.
    - `name` string
    - `area_ha` number, nullable: Paddock area in hectares. Measured from the boundary when `area_source` is `drawn`; the farmer's own number when it is `typed`.
    - `area_source` 'typed' | 'drawn', nullable: Where `area_ha` came from. A `typed` area is never overwritten by a drawn one.
    - `land_use` 'cropping' | 'grazing' | 'mixed' | 'fallow', nullable
    - `current_crop` string, nullable
    - `boundary` array[], nullable: The paddock outline: an array of rings, each ring an array of `[longitude, latitude]` pairs in RFC 7946 order — **longitude first** — with at least 4 positions and the first repeated last. Not a GeoJSON object (see `PaddockBoundaryModel`).
      - array[]: One closed exterior ring.
        - number[]: [longitude, latitude]
    - `has_boundary` boolean: Whether the paddock has an outline at all — the cheap face of `boundary`.
    - `withholding` object, nullable: Is the paddock under a grazing or harvest withholding period right now? The latest spray record whose graze or harvest date is still ahead, or null. **Derived, not stored.** Read-only. Served on the paddock's own read and on lists (SPRAY_RECORD.md).
      - `task_id` string
      - `record_id` string: The SprayRecord id.
      - `safe_to_graze_on` string, date, nullable
      - `safe_to_harvest_on` string, date, nullable
      - `products` string[]
    - `boundary_captured_at` string, date-time, nullable
    - `boundary_source` 'traced' | 'grid' | 'gps' | 'imported', nullable: How the ring was captured — traced over imagery, placed on the grid with no imagery, walked with the phone's GPS, or read from a KML/shapefile. Null for a ring saved before provenance was recorded or by a caller that named no source. Written with the ring and cleared with it.
    - `boundary_captured_by` string, nullable: Id of the user who saved the ring, stamped server-side from the request's actor and never accepted from a client. Null when a machine token saved it, and null while the paddock has no ring.
    - `archived` boolean: An archived paddock leaves the map and the lists; its records stay on the property.
    - `archived_at` string, date-time, nullable
    - `block_id` string, uuid, nullable: The block the paddock sits in. Null in the home block.
    - `record_count` integer: Completed rows on this paddock — its diary.
    - `open_task_count` integer: Pending rows on this paddock.
    - `last_record_at` string, date-time, nullable
    - `created_at` string, date-time
    - `updated_at` string, date-time
    - `farm` object: Present when include=farm
  - `meta` PaginationMeta
    - `current_page` number
    - `next_page` number, nullable
    - `prev_page` number, nullable

## Other responses

- `401`: Unauthorized
- `403`: Forbidden
- `404`: Not Found
- `422`: A missing name, a name already used on the property (live or archived), or an unknown land use
