base.html passed the cache-busting query string INSIDE the filename argument:
url_for('static', filename='uploads/header_logo.png?v=1')
Flask percent-encodes the '?' to '%3F', producing a request for a file
literally named "header_logo.png%3Fv=1", which does not exist. Every
authenticated page therefore logged:
GET /static/uploads/header_logo.png%3Fv=1 404
The logo silently stayed hidden too, because the element carries
onerror="this.style.display='none'".
Changes:
- base.html / login.html: append "?v=..." OUTSIDE url_for(), matching what
admin/customize_logos.html already did correctly.
- Inject logo_version from a context processor instead of hardcoding it.
It is derived from the newest logo's mtime, so uploading a new logo in
Admin -> Customize Logos is reflected immediately. The previous value was
a literal 1, which defeated cache-busting entirely; login.html used
range(1, 999999) | random, which changed on every request and made the
logo uncacheable.
Verified: /, /content/ and /players/ now render
/static/uploads/header_logo.png?v=<mtime> (HTTP 200), and no %3F requests
appear in the logs.
DigiServer v2 — Project Documentation
Comprehensive technical documentation generated with Graphify — an interactive knowledge-graph engine for AI-assisted coding.
Version: 2.0.0 · Build date: 2025-11-12 · Generated: 2026-08-16
DigiServer v2 is a digital signage management server built with Flask. It manages media content (images, videos, PDFs, presentations), organizes it into playlists, assigns players (physical signage displays), and remotely deploys and monitors those players over SSH — including HTTPS/SSL provisioning via Caddy and an on-player photo-editing pipeline.
