# Assessment Results Backend
|
|
|
|
## Purpose
|
|
|
|
`assessment_results` is the per-organization join between an assessment and a student, holding
|
|
that student's score, letter grade, and remarks for the assessment. It is a generic-CRUD slice
|
|
assembled from the shared factories; the backend is the source of truth for these records.
|
|
|
|
## Slice Files (by layer)
|
|
|
|
- Route: `src/routes/assessment_results.ts` — `createCrudRouter(controller, { permission: 'assessment_results' })`.
|
|
- Controller: `src/api/controllers/assessment_results.controller.ts` — `createCrudController(service, { csvFields })`.
|
|
- Service (BLL): `src/services/assessment_results.ts` — `createCrudService(DbApi, { notFoundCode: 'assessment_resultsNotFound' })`.
|
|
- Repository (DAL): `src/db/api/assessment_results.ts` (`Assessment_resultsDBApi`) —
|
|
entity-specific `create`/`bulkImport`/`update`/`findBy`/`findAll`;
|
|
`remove`/`deleteByIds`/`findAllAutocomplete` delegate to `db/api/shared/repository.ts`.
|
|
- Model: `src/db/models/assessment_results.ts`.
|
|
- Shared used: CRUD factories (`services/shared/crud-service.ts`,
|
|
`api/controllers/shared/crud-controller.ts`, `api/http/crud-router.ts`), repository helpers
|
|
(`db/api/shared/repository.ts`), `shared/constants/pagination.ts` (`resolvePagination`).
|
|
|
|
## API
|
|
|
|
The standard generic-CRUD surface (all under `/api/assessment_results`, JWT +
|
|
`${METHOD}_ASSESSMENT_RESULTS` permission, all `200`) — see `backend-architecture.md` for the
|
|
shared contract:
|
|
|
|
- `POST /` — body `{ data }`, returns `true`.
|
|
- `POST /bulk-import` — multipart CSV file, returns `true`.
|
|
- `PUT /:id` — body `{ data, id }` (the service reads the id from the **body**), returns `true`.
|
|
- `DELETE /:id` — returns `true`.
|
|
- `POST /deleteByIds` — body `{ data: string[] }`, returns `true`.
|
|
- `GET /` — query filters, returns `{ rows, count }`; `?filetype=csv` streams a CSV of `csvFields`.
|
|
- `GET /count` — returns `{ rows: [], count }`.
|
|
- `GET /autocomplete` — `?query&limit&offset`, returns `[{ id, label }]` where `label` is
|
|
`grade_letter`.
|
|
- `GET /:id` — returns the record with eager associations (see Data Contract).
|
|
|
|
`csvFields`: `id`, `remarks`, `score`.
|
|
|
|
## Access Rules
|
|
|
|
- JWT required; the whole router is guarded by `checkCrudPermissions('assessment_results')`,
|
|
deriving `READ_ASSESSMENT_RESULTS` / `CREATE_ASSESSMENT_RESULTS` / `UPDATE_ASSESSMENT_RESULTS`
|
|
/ `DELETE_ASSESSMENT_RESULTS` per HTTP method.
|
|
- Access is granted by role permission or per-user `custom_permissions` (see `permissions.md`).
|
|
|
|
## Tenant Scope
|
|
|
|
- `findAll` scopes `where.organizationId` to `currentUser.organizationId`; a `globalAccess`
|
|
role clears the org filter (sees all tenants).
|
|
- `create` assigns the organization from `currentUser.organizationId`; `update` only reassigns
|
|
organization for `globalAccess` users (otherwise it stays the caller's org).
|
|
|
|
## Data Contract
|
|
|
|
Model columns (`paranoid`, soft-delete via `deletedAt`):
|
|
|
|
- `id` (UUID PK), `remarks` (TEXT, nullable).
|
|
- `score` — DECIMAL (nullable).
|
|
- `grade_letter` — ENUM `A` | `B` | `C` | `D` | `E` | `F` | `P` | `N`.
|
|
- `importHash` (unique), `organizationId`, `assessmentId`, `studentId`, `createdById`,
|
|
`updatedById`, timestamps.
|
|
|
|
Associations: `belongsTo` organization, assessment (assessments), student (students),
|
|
createdBy/updatedBy (users). `findBy`/`GET /:id` eager-load `organization`, `assessment`, and
|
|
`student` in a single `Promise.all`.
|
|
|
|
List filters (`AssessmentResultsFilter`): `id`, `remarks`, `scoreRange`, `active`,
|
|
`grade_letter`, `assessment` (id or assessment `name`, `|`-separated, applied as an `include`
|
|
where-clause), `student` (id or `student_number`, `|`-separated, applied as an `include`
|
|
where-clause), `organization` (`|`-separated ids), `createdAtRange`, plus `field`/`sort`
|
|
ordering and `limit`/`page` pagination.
|
|
|
|
## Behavior / Notes
|
|
|
|
- `create`/`update` set the `assessment`, `student`, and `organization` associations from the
|
|
ids in the request body.
|
|
- `bulkImport` offsets `createdAt` per row by `BULK_IMPORT_TIMESTAMP_STEP_MS` to preserve order.
|
|
- List pagination uses the shared `resolvePagination` defaults (page size 10, capped at 100).
|
|
- Note: `AssessmentResultsFilter` accepts an `active` flag the model has no column for; it is
|
|
currently inert (kept for source accuracy).
