Diagnoses and resolves Ecto database constraint violations in Elixir and Phoenix applications.
The Ecto Constraint Debugger provides a systematic framework for troubleshooting Ecto.ConstraintError occurrences, ranging from unique index violations to foreign key failures. It guides developers through a rigorous verification process—parsing constraint names from logs, auditing migrations against schema definitions, and tracing concurrent insert paths—to identify root causes like race conditions or missing transaction isolations. By applying proven fix patterns such as upserts or data backfills, it helps maintain data integrity and reduces runtime errors in Phoenix and LiveView applications.
