Línea de trabajo

Start in core/map_projects/serializers.py and trace MapProjectSerializer, MapProjectDetailSerializer and the create/update serializer; then inspect MapProject.jsx to follow how Context is loaded and saved. Check whether Create similar copies configurations, including the configurations/ path named in the issue. Add coverage for saving Context, reading it after reload and saving again; done when the API returns the saved description and the round trip preserves it.

Descripción

component/api component/mapper decision/human-review signal/needs-human signal/quick-win signal/small-scope signal/well-specified stage/triaged type/bug

Found on production (API 2.3.227, Mapper 1.0.31-beta) on 2026-10-20 while preparing the OHDSI 2026 Mapper demo.

The Mapper's Context field (Configure) is stored in MapProject.description. MapProjectCreateUpdateSerializer accepts it, but no read serializer returns it:

  • core/map_projects/serializers.py: MapProjectSerializer.Meta.fields, and so MapProjectDetailSerializer, leave out description. MapProject.CONFIGURATION_FIELDS doesn't include it either.
  • oclmap loads it with setDescription(response.data?.description || '') (MapProject.jsx), so it always loads '', and every save sends description back (formData.append('description', description)).

Reproduced on a project:

  1. Enter Context and save. The map_projects row has the text.
  2. Reload the project. Context is blank.
  3. Save again for any reason. description is now '' in the database.

Every user who fills in Context loses it on the next save after a reload, with no warning.

Acceptance criteria

  • GET on a map project returns description.
  • After a reload the Mapper shows the saved Context, and saving keeps it.
  • Decide whether Create similar copies Context; if so, include it in configurations/.
  • A test covers the save, read and save-again round trip.
