djust 0.3.6rc3

Pre-releaseReleased
GitHub release

This is a pre-release. djust 0.3.6 has shipped since: read the djust 0.3.6 release notes.

Before you upgrade, read Breaking Changes, Deprecated below.

Breaking Changes

  • model.id now returns the native type, not a string — _serialize_model_safely() previously wrapped obj.pk with str() when producing the "id" key, causing template comparisons like {% if edit_id == todo.id %} to fail silently when edit_id was an integer. model.id now matches model.pk and returns the native Python type (e.g. int, UUID). Migration: if your templates or event handlers compare model.id against string literals or string-typed variables, update them to use the native type. PR #262 fixed .pk; this PR (#472) completes the fix for .id.

Fixed

  • djust cache --all now correctly clears all sessions on the Redis backend — The CLI called cleanup_expired(ttl=0) to force-clear sessions, but the semantics of ttl=0 changed in 0.3.5 to mean "never expire". The command now calls the explicit delete_all() method, which uses a Redis pipeline for an efficient single round-trip bulk delete. (#409)
  • dj-params attribute no longer silently dropped — Between 0.3.2 and 0.3.6rc2, dj-params was removed from the client event-binding code. Templates using dj-params='{"key": value}' continued to fire click events but the server received params: {}. The attribute is now read and merged into the params object for backward compatibility. A console.warn is emitted in debug mode (globalThis.djustDebug) to notify developers to migrate. (#469)
  • Prefetch Set not cleared on SPA navigation — The client-side _prefetched Set persisted across live_redirect navigations, preventing links on the new view from being prefetched. Added clear() to window.djust._prefetch and call it in handleLiveRedirect() so each SPA navigation starts with a fresh prefetch state. (#402)
  • Auto-reload on unrecoverable VDOM state — When VDOM patch recovery fails because recovery HTML is unavailable (e.g. after server restart), the client now auto-reloads the page instead of showing a confusing error overlay. The server sends recoverable: false to signal the client. (#421)
  • {% djust_pwa_head %} and other custom tags with quoted arguments containing spaces now render correctly — The Rust template lexer used split_whitespace() to tokenize tag arguments, which broke quoted values like name="My App" into separate tokens (name="My and App"). This caused the downstream Python handler to receive malformed arguments, silently returning empty output. Replaced with a quote-aware splitter (split_tag_args) that preserves quoted strings as single arguments. (#419)
  • {% load %} tags stripped during template inheritance, breaking inclusion tags — The Rust parser treated {% load %} as Node::Comment, which nodes_to_template_string() discarded during inheritance reconstruction. When the resolved template was re-parsed, custom tags that relied on Django tag libraries (e.g. {% djust_pwa_head %}) could silently fail. Fixed by adding a dedicated Node::Load variant that preserves library names through reconstruction. Also improved _render_django_tag() error handling: failures now log a full traceback via logger.exception() and return a visible HTML comment instead of an empty string. (#418)
  • Checkbox/radio checked and <option>selected state not updated by VDOM patches — SetAttr and RemoveAttr patches only called setAttribute/removeAttribute, which updates the HTML attribute but not the DOM property. After user interaction the browser separates the two, so server-driven state changes via dj-click had no visible effect on checkboxes, radios, or select options. Fixed by syncing the DOM property alongside the attribute. Also fixed createNodeFromVNode to set .checked/.selected when creating new elements. (#422)
  • SESSION_TTL=0 breaks all event handling (no DOM patches) — cleanup_expired() methods in both InMemoryStateBackend and RedisStateBackend now treat TTL ≤ 0 as "never expire". Previously SESSION_TTL=0 caused cutoff = time.time() - 0, making all sessions appear expired, deleting them immediately, and leaving no state for VDOM patches. (#395)
  • WebSocket session extraction crashes on Django Channels LazyObject — Replaced hasattr(scope_session, "session_key") with getattr(scope_session, "session_key", None) in the consumer's request context builder. hasattr() on a Django Channels LazyObject can raise non-AttributeError exceptions during lazy evaluation, causing the consumer to crash silently. (#396)

Deprecated

  • dj-params JSON blob attribute — Use individual data-* attributes with optional type-coercion suffixes instead. dj-params will be removed in a future release.

    Migration guide (0.3.2 → 0.3.6):

    <!-- Before (0.3.2) -->
<button dj-click="start_edit" dj-params='{"todo_id": {{ todo.id }}}'>Edit</button>
<button dj-click="set_filter" dj-params='{"filter_value": "all"}'>All</button>

<!-- After (0.3.6+) -->
<button dj-click="start_edit" data-todo-id:int="{{ todo.id }}">Edit</button>
<button dj-click="set_filter" data-filter-value="all">All</button>

    Type-coercion suffixes: :int, :float, :bool, :json. Kebab-case attribute names are auto-converted to snake_case for server handler parameters.

Added

  • djust-deploy CLI — new python/djust/deploy_cli.py module providing deployment commands for djustlive.com. Available via the djust-deploy entry point after installation. (#437)

    • djust-deploy login — prompts for email/password, authenticates against djustlive.com, and stores the token in ~/.djustlive/credentials (mode 0o600)
    • djust-deploy logout — calls the server logout endpoint and removes the local credentials file
    • djust-deploy status [project] — fetches current deployment state; optionally filtered by project slug
    • djust-deploy deploy <project-slug> — validates the git working tree is clean, triggers a production deployment, and streams build logs to stdout
    • --server flag / DJUST_SERVER env var to override the default server URL (https://djustlive.com) See docs/website/guides/djust-deploy.md.

  • TypeScript type stubs updated — DjustStreamOp now includes "done" and "start" operation types and an optional mode field ("append" | "replace" | "prepend"). getActiveStreams() return type changed from Map to Record. See docs/website/guides/typecheck.md.

  • .flex-between CSS utility class — Added to demo project's utilities.css for laying out flex children horizontally with space-between. Use on card headers or any flex container that needs a title on the left and action widget on the right. (#397) See docs/website/guides/css-frameworks.md.

  • Debug toolbar state size visualization — New "Size Breakdown" table in State tab shows per-variable memory and serialized byte sizes with human-readable formatting (B/KB/MB). Added _debug_state_sizes() method to PostProcessingMixin included in both mount and event debug payloads. (#459)

  • Debug panel TurboNav persistence — Event, patch, network, and state history now persist across TurboNav navigation via sessionStorage (30s window). Panel state restores on next page if navigated within 30 seconds. (#459) See docs/website/advanced/debug-panel.md.

  • TurboNav integration guide — Comprehensive guide covering setup, navigation lifecycle, inline script handling, known caveats, and design decisions: docs/guides/turbonav-integration.md. (#459)

  • Debug panel search extended to Network and State tabs — The search bar in the debug panel now filters across all data tabs. The Network tab shows a N / total count label when a query narrows the message list (#530). The State tab filters history entries by trigger, event name, and serialized state content, with the same N / total count label (#520). Overlapping nameFilter and searchQuery on the Events tab now correctly apply AND semantics (#532). (#541)
