v2.1.1

netbox-custom-objects-tab v2.1.1

Highlights

Deferred DB queries — Typed-tab registration no longer queries the database during AppConfig.ready(), eliminating startup warnings from Django and netbox_branching.

What's Fixed

Fixed

• Deferred typed-tab initialization — DB-dependent work (typed-tab registration, CO URL injection, registry deduplication) is now deferred to the first HTTP request via Django's request_started signal. This prevents:
  • Django warning: "Accessing the database during app initialization is discouraged"
  • netbox_branching warning: "Routing database query before branching support is initialized"
• Combined tabs continue to register immediately during ready() (no DB access needed).
• Thread-safe one-shot handler ensures deferred init runs exactly once, then disconnects itself.

Fixes #4

How It Works

register_tabs() is now two-phase:

1. Phase 1 (ready()) — registers combined tabs (factory pattern, no DB queries)
2. Phase 2 (first request) — a one-shot request_started signal handler registers typed tabs, injects CO URL patterns, and deduplicates the view registry
