# PurchaseRequest

> **Last updated:** 2026-06-03 — added Postgres / Drizzle schema section, child-table breakdowns, migration status, and dispute/escrow hold fields present in both Mongo and PG schemas.

The central buyer-side document. A `PurchaseRequest` captures what a buyer wants to acquire (physical product, digital product, service, or consultation), the budget envelope, urgency, delivery details, and the entire lifecycle from creation through payment, delivery, and completion. Sellers respond by attaching [[SellerOffer]] documents; the buyer accepts one, a [[Payment]] is opened, and delivery is verified by a 6-digit code.

> [!note] Sources
> Mongo model: `backend/src/models/PurchaseRequest.ts:95` — schema definition; `:387` — model export
> Drizzle schema: `backend/src/db/schema/purchaseRequest.ts`

## Migration Status

**DUAL-WRITE active** — part of `DualWriteMarketplaceRepo`. Writes go to both Mongo and Postgres; reads still come from Mongo. Backfill and read-cutover are human-gated and not yet executed.

### Status enum — all valid values

`pending_payment` · `pending` · `active` · `received_offers` · `in_negotiation` · `payment` · `processing` · `delivery` · `delivered` · `confirming` · `completed` · `seller_paid` · `cancelled`

**Note:** `finalized` and `archived` are **not** valid status values and do not appear in the `IPurchaseRequest` frontend type or the Mongoose schema enum. Using either would cause a validation error.

### Virtuals

None defined.

## Postgres / Drizzle Schema

Source: `backend/src/db/schema/purchaseRequest.ts`

The PG model normalises the embedded Mongo subdocuments into 7 tables. The `offers[]` array is dropped; [[SellerOffer]] holds `purchase_request_id` as a back-reference.

### Design Notes

- **`offers[]` dropped in PG.** The Mongo `offers[]` array is not migrated. Query `SellerOffer WHERE purchase_request_id = ?` instead.
- **Money scale.** `budget_min` / `budget_max` use `numeric(38,18)` (project-wide crypto convention) rather than the `numeric(15,8)` suggested in the migration guide, for consistency with `Payment` and `FundsLedgerEntry`.
- **`tags` / `attachments`** stored as `text[]` (not JSONB) to enable `ANY()` array queries without a child table.
- **`legacy_object_id`** on every table uses a partial-unique index (`WHERE NOT NULL`) for idempotent backfill upserts.
- **Dispute / escrow hold fields** (`dispute_raised`, `dispute_raised_at`, `dispute_resolved`, `dispute_resolved_at`, `dispute_hold_reason`, `hold_until`) are present in both the Mongo interface (`IPurchaseRequest`) and the PG main table. They were added to the Mongo schema before the PG migration and are considered escrow-critical.

---

## Relationships

- **References**: [[User]] (`buyerId`, `preferredSellerIds[]`, `deliveryInfo.deliveryCodeUsedBy`, `deliveryInfo.deliveryAttempts[].sellerId`), [[Category]] (`categoryId`), [[SellerOffer]] (`offers[]` Mongo only, `selectedOfferId`).
- **Referenced by**: [[SellerOffer]] (`purchaseRequestId`), [[Payment]] (`purchaseRequestId`), [[Dispute]] (`purchaseRequestId`), [[Chat]] (`relatedTo.id` when `relatedTo.type === 'PurchaseRequest'`), [[Review]] (`purchaseRequestId`).

## Template Checkout Mapping

When a buyer converts a [[RequestTemplate]], the seller's template remains authoritative for delivery mode:

- `physical` templates require a buyer billing/delivery address in checkout. The generated request stores both `deliveryInfo.address` and `deliveryInfo.deliveryAddress`.
- `online` templates require a buyer email in checkout. The generated request stores it in `deliveryInfo.email`.
- Mixed carts can produce multiple requests with different delivery modes; the checkout UI asks for the union of required buyer details.

## Common Queries

```ts
// Buyer's open requests
PurchaseRequest.find({ buyerId, status: { $in: ['pending', 'active', 'received_offers'] } });

// Public marketplace feed
PurchaseRequest.find({ isPublic: true, status: 'active' }).sort({ createdAt: -1 });

// Sellers' eligible queue
PurchaseRequest.find({ productType, status: 'active', categoryId });

// Populate offers (Mongo only — offers[] array is not in PG)
PurchaseRequest.findById(id).populate('offers').populate('selectedOfferId');

// Redeem delivery code
PurchaseRequest.findOneAndUpdate(
  { _id: id, 'deliveryInfo.deliveryCode': code, 'deliveryInfo.deliveryCodeUsed': false },
  { $set: { 'deliveryInfo.deliveryCodeUsed': true, 'deliveryInfo.deliveryCodeUsedAt': new Date() } }
);

// PG: offers for a request
// SELECT * FROM seller_offers WHERE purchase_request_id = $1;

// PG: find requests with live escrow hold
// SELECT * FROM purchase_requests WHERE hold_until IS NOT NULL AND hold_until > now();
```
