When you include it in your Pyramid application, every request gets its own transaction context that commits on success or aborts on exception, eliminating manual transaction boilerplate in request handlers.\n\nThe package runs as a Pyramid tween (middleware layer) positioned to wrap exception views, meaning the transaction remains active even when handling errors. It supports customization through hooks like commit_veto to override commit/abort decisions, and tm.annotate_user to track authenticated users in transaction logs. It integrates with pyramid_retry for automatic transaction retry on transient errors.","worth_installing":"Yes. pyramid_tm is a mature, actively maintained package (last release November 2024) with no known vulnerabilities, low install friction, and a permissive license.
