Support WorkerRun on Transcription
- add
worker_run_idFK onTranscription(nullable, blank) - make it available in the admin details of an Transcription, using
raw_id_field - expose it in
CreateTranscriptionsendpoint (required for PyLAIA) - bonus: expose it in
CreateTranscriptionendpoint
Rules for endpoints:
- we only support
worker_version_idXORworker_run_id, raise a 400 if both are supplied - the endpoint must load the
WorkerRunfrom its ID to check its existence - and use the related
WorkerVersionasworker_version_idon the resulting transcriptions (so we end up with both worker_version & worker_run being set on the Transcription)
