Description of Changes

Added conditional inclusion of websocket routes from openwisp_firmware_upgrader.routing.get_routes() in the Channels routing.py template, gated behind the openwisp2_firmware_upgrader variable.

This is required to support real-time upgrade progress tracking via WebSockets, introduced in openwisp/openwisp-firmware-upgrader#320.

📝 Walkthrough

Walkthrough

This PR adds conditional integration of firmware upgrader websocket routes to the routing template. When the openwisp2_firmware_upgrader feature is enabled, the template now imports get_routes from openwisp_firmware_upgrader.routing and extends the shared routes list with the returned websocket patterns, maintaining compatibility with existing extra websocket routes and the protocol type router construction.
