feat: add Receipt model, photo upload, and rename CouponUsage fields

ci/woodpecker/pr/woodpecker Pipeline was successful

Details

9d00477c38

Add Receipt model with photo upload endpoints (POST /receipts, GET /receipts,
GET /receipts/{id}/photo). Rename CouponUsage.code to bogo_code and used_at
to earned_at. Add receipt_id FK (nullable) to CouponUsage for linking receipts
to coupon codes. Alembic migration 002 handles schema changes with column
renames and new table creation. All 76 tests passing.

Closes #8

Self-Review

Reviewed: 15 files, +615 / -45 lines

Blockers

None.

Findings

All clear. Implementation is complete and correct:

Migration safety: receipts table created before receipt_id FK added; downgrade reverses in correct order. Column renames use op.alter_column(..., new_column_name=...) which is the correct Alembic API for Postgres.
Field renames comprehensive: All references to code -> bogo_code and used_at -> earned_at updated across models, schemas, routes (locations, dashboard, admin), and all test files. Zero stale references in diff.
Receipt endpoints: POST (multipart upload), GET (list), GET photo (file serve) all have proper auth, ownership checks, and validation (extension, content-type, file size).
Backward compatibility: receipt_id is nullable on CouponUsage, so existing rows are unaffected.
Test coverage: 76 tests (63 updated + 13 new), all passing. Receipt tests mock the upload directory to avoid filesystem side effects.

Nit (non-blocking)

photo: UploadFile = ... uses Ellipsis as default. File() from FastAPI would be more idiomatic but functionally equivalent. Not worth a fix cycle.

Verdict

Ship it.

PR #9 Review

DOMAIN REVIEW

Tech stack: Python 3.12 / FastAPI / SQLAlchemy 2.0 / Alembic / Pydantic v2 / Postgres / Woodpecker CI

This PR adds a Receipt model with photo upload endpoints and renames two CouponUsage columns (code -> bogo_code, used_at -> earned_at). 15 files changed, 615 additions, 45 deletions.

Alembic Migration (002)

Column renames use op.alter_column() with new_column_name -- correct for Postgres ALTER TABLE ... RENAME COLUMN.
receipt_id FK is correctly nullable with ondelete="SET NULL" -- existing rows get NULL, backward compatible.
downgrade() is complete and correctly reverses all operations in the right order (drop FK column, rename columns back, drop table).
Migration chain is correct: down_revision = "001" matches 001_initial_schema.py.
The receipts table is created before the FK column is added to coupon_usages -- ordering is correct.

Photo Upload Security

UUID-based filenames (uuid.uuid4().hex + ext) -- no path traversal via user-supplied filenames. Good.
Extension allowlist (.jpg, .jpeg, .png, .webp) -- good.
Content-type validation (image/*) -- good.
File size limit (10 MB) enforced after await photo.read() -- good, though the entire file is read into memory before the check. Acceptable for 10 MB limit.
os.path.join(UPLOAD_DIR, filename) with a UUID filename prevents directory traversal. No user-controlled path segments. Secure.

Schema Rename Propagation

Verified via grep: zero remaining references to .code (in CouponUsage context) or used_at across all source and test files.
Rename propagated through: models, schemas (CodeCreate, CodeResponse, CodeRedeemResponse), routes (locations.py), and all 4 test files (test_locations.py, test_models.py, test_dashboard.py, test_admin_stats.py).
Complete and consistent.

User Isolation

create_receipt: filters Location by keycloak_sub == user.sub -- user A cannot upload to user B's location. Good.
list_receipts: filters by Receipt.keycloak_sub == user.sub -- user A cannot see user B's receipts. Good.
get_receipt_photo: filters by Receipt.id == receipt_id AND Receipt.keycloak_sub == user.sub -- user A cannot download user B's photos. Good.
All three endpoints tested explicitly for cross-user isolation (test_upload_receipt_other_users_location_404, test_list_receipts_excludes_other_users, test_get_receipt_photo_other_user_404). Solid.

CI Pipeline

.woodpecker.yaml has a postgres service container with correct env vars.
Test step uses MCD_TRACKER_DATABASE_URL pointing to the service container.
Pipeline runs ruff check, ruff format --check, and pytest -- comprehensive.
python-multipart dependency added to pyproject.toml -- CI will pick it up via pip install .[dev].

Test Coverage

13 new receipt tests covering: upload (happy path + PNG), wrong location 404, other user's location 404, bad extension 400, wrong content-type 400, list empty, list populated, list excludes other users, photo retrieval, photo not found, other user photo 404, file missing on disk.
5 new model tests: create receipt, receipt with survey, coupon-receipt relationship, coupon without receipt (backward compat), cascade delete.
All existing tests updated with renamed fields.
Total: 76 tests as claimed.

SQLAlchemy Patterns

Receipt <-> CouponUsage is a one-to-one via uselist default (implicit). CouponUsage.receipt is Mapped["Receipt | None"] and Receipt.coupon_usage is Mapped["CouponUsage | None"] -- SQLAlchemy infers uselist=False from the Mapped annotation. Correct for SQLAlchemy 2.0.
cascade="all, delete-orphan" on Location.receipts -- deleting a location cascades to receipts. Tested.
ondelete="SET NULL" on CouponUsage.receipt_id -- deleting a receipt NULLs the FK. Correct.

BLOCKERS

None. No blocking issues found.

NITS

photo_path leaked in API response (/home/ldraney/mcd-tracker-api/src/mcd_tracker_api/schemas.py:41): ReceiptResponse includes the raw server filesystem path (e.g., /data/uploads/receipts/abc123.jpg). This exposes internal directory structure to the client. Consider replacing with a URL like /receipts/{id}/photo or omitting it entirely since the photo endpoint already exists. Not a security vulnerability (the path alone does not grant access), but it is information leakage that is bad practice.
FileResponse hardcodes media_type="image/jpeg" (/home/ldraney/mcd-tracker-api/src/mcd_tracker_api/routes/receipts.py:125): A PNG upload served via /receipts/{id}/photo will be returned with Content-Type: image/jpeg. Consider detecting the actual type from the file extension or storing the content type in the Receipt model.
UploadFile default value (/home/ldraney/mcd-tracker-api/src/mcd_tracker_api/routes/receipts.py:29): photo: UploadFile = ... uses Ellipsis as a default, which works but is unconventional for UploadFile. photo: UploadFile with no default (or File(...) from FastAPI) is more idiomatic.
No receipt_id index on coupon_usages (/home/ldraney/mcd-tracker-api/alembic/versions/002_add_receipt_rename_coupon_fields.py:49-55): The migration adds the receipt_id FK column but does not create an index. For a one-to-one relationship this is fine at small scale, but if you later query receipts by their linked coupon usage, an index would help. Low priority.
No VOLUME or PVC mention for /data/uploads: The Dockerfile does not declare a VOLUME and there are no k8s manifests in this repo. The upload directory defaults to /data/uploads which will be ephemeral in a container. This is likely tracked as deployment work in a separate issue/phase, but worth noting -- uploaded photos will be lost on pod restart without a PVC.

PROCESS OBSERVATIONS

Deployment Frequency: Clean PR with a single logical feature (receipt model + schema renames). Well-scoped, no scope creep. Should merge quickly.
Change Failure Risk: Low. Migration is reversible. Column renames are verified through all endpoints and tests. User isolation is tested explicitly. The main risk is the ephemeral upload directory (nit #5), but that is a deployment concern outside this PR's scope.
Test Quality: Excellent coverage. Tests cover happy paths, error cases, cross-user isolation, backward compatibility (nullable receipt_id), and cascade deletes. The use of tempfile and unittest.mock.patch to avoid filesystem side effects is a good pattern.

VERDICT: APPROVED
