Button actions are the current focus, enabling request-capable buttons with action and method attributes, plus form HTTP method upgrades and partial DOM replacement.

Haki Benita shows how carefully crafted check constraints can achieve partition pruning in PostgreSQL even when filtering by non-partition key columns.
CPython’s visible CVE output is rising, but the bigger story is the surge in incoming reports handled by the Python Security Response Team, including GitHub Security Advisories and older email threads. Charts show a sharp climb since 2025 and halfway through 2026, plus context on how PSRT guidance and the shift to GHSA reporting affect what gets counted.
django-orjson wraps orjson’s faster Rust-backed JSON serialization and deserialization as drop-in replacements for Django and Django REST Framework pieces like JsonResponse, test client parsing, and the json_script template tag. The project also points to a Django feature proposal to make pluggable JSON backends a first-class option, listing multiple Django integration points.
Django raw cursor code that used IN %s with a tuple can fail on Postgres with psycopg 3, producing syntax errors like IN '(1,2,3)'. Switch to WHERE some_value = ANY(%s) and pass a list (not a tuple), and for lists of strings either keep ANY with correctly typed columns or build an OR chain with one %s per value for a safe, parameterized query.
Use gc.get_objects() to scan the garbage collector’s tracked objects and filter with isinstance(obj, MyClass) to find all current instances, without changing the class code. For debugging, prefer a generator with Counter when you only need aggregated data, and delete any temporary instance lists so you do not accidentally keep objects alive.
Partitioned tables prune only when queries include the partition key, leaving common lookups like session_id stuck scanning every partition. This guide shows how to use per-partition CHECK constraints to “talk to” the planner so filtering by a correlated non-key column can eliminate irrelevant partitions, with an outlier-friendly approach based on multiple ranges.
