Resolve 3 merge conflicts and renumber the automation_hooks migration to follow main's migration chain (036_add_document_translation_fields). Conflicts resolved: - app/api/__init__.py: add automation_router alongside main's new routers - app/utils/settings_service.py: add automation_hooks_enabled alongside compliance_enabled - tests/conftest.py: add AutomationHook alongside AuditLog/ComplianceTemplate imports Migration renumbered: - 027_add_automation_hooks → 037_add_automation_hooks - down_revision: 026_add_scheduled_jobs → 036_add_document_translation_fields Co-authored-by: christianlouis <361235+christianlouis@users.noreply.github.com>

|
The caller is responsible for computing ``effective_mime_types`` and
|
|
``effective_extensions`` from the relevant :class:`ImapIngestionProfile` (or
|
|
the global default) via :func:`app.utils.allowed_types.get_allowed_types_for_categories`
|
|
before calling this function. ``pull_inbox`` does this automatically.
|
|
|
|
If either set is ``None`` the function falls back to the default category list
|
|
so the function still works correctly when called directly in tests or from
|
|
other contexts.
|
|
|
|
If the attachment is a PDF (by extension or MIME type), it is enqueued for upload;
|
|
any other allowed file is enqueued for conversion to PDF.
|
|
|
|
Args:
|
|
email_message: The parsed email message to extract attachments from.
|
|
owner_id: Optional user identifier forwarded to ``process_document`` /
|
|
``convert_to_pdf`` for multi-tenant attribution.
|
|
effective_mime_types: Pre-computed frozenset of allowed MIME type strings.
|
|
effective_extensions: Pre-computed frozenset of allowed file extension strings.
|
|
|
|
Returns True if at least one allowed attachment was processed.
