Change Log

Unreleased

0.5.0 - 2026-01-29

Added

• Credential validation and invalidation system with INVALIDATED status.

• verify_uuid field on credentials — a separate UUID used for third-party verification, distinct from the primary key.

• invalidated_at timestamp and invalidation_reason fields on the Credential model.

• learning_context_name cached field on credentials for use in validation display.

• Public API endpoint (/api/learning_credentials/v1/metadata/<uuid>/) to retrieve credential metadata by verification UUID.

• “Reissue credential” admin action that invalidates the current credential and generates a new one.

• {verify_uuid} placeholder support in PDF text elements.

• Admin test suite (test_admin.py) and included it in test coverage.

Changed

• Replaced user_id (IntegerField) with a user ForeignKey to the User model.

• Added configuration ForeignKey on Credential linking to CredentialConfiguration, replacing credential_type and learning_context_key lookups.

• Simplified generate_pdf_credential() signature to accept a Credential object instead of separate parameters.

• Changed the PDF output directory from hardcoded external_certificates/ to the configurable LEARNING_CREDENTIALS_OUTPUT_DIR setting.

• Credential issue date on PDFs now uses the credential’s creation date instead of the current time.

• get_localized_credential_date() now accepts an explicit datetime parameter.

• Disabled add and delete permissions for credentials in the Django admin.
