"""Make help-center upload URLs relative (strip baked-in absolute host)
|
|
|
|
Revision ID: rel_hc_uploads_001
|
|
Revises: add_hc_favicon_001
|
|
Create Date: 2026-07-25
|
|
|
|
Article images (baked into faqs.answer markdown) and, historically, some
|
|
logo/favicon rows carried an absolute host in front of the /api/v1/uploads/
|
|
path (e.g. http://localhost:8000/api/v1/uploads/...). That breaks the moment the
|
|
help center is viewed from any other origin. Convert those to relative paths so
|
|
they resolve against whichever origin serves the page. S3 URLs (no
|
|
/api/v1/uploads/ segment) and already-relative paths are left untouched.
|
|
Irreversible best-effort — downgrade is a no-op.
