schema-drift-detector

Detect schema.rb drift in a pull request by cross-referencing the file against included database migrations to identify extra columns, tables, indexes, or version mismatches not present in the PR's migrations.

Schema drift occurs when a schema.rb file contains unrelated database changes from other branches. Detecting it before merging prevents accidental inclusions that lead to merge conflicts and confusion.

Verify schema integrity by comparing the schema.rb file against database migrations included in the pull request. The detector flags extra columns, tables, indexes, and version mismatches not covered by those migrations.

Yes, the drift detector flags extra columns, tables, indexes, and version mismatches by cross-referencing schema.rb changes against the database migrations included within the specific pull request.

No external dependencies are required. The schema drift detector runs as a standalone script with reference components, comparing schema.rb against migrations to ensure schema integrity before merging code.

Run drift detection when reviewing a pull request that includes database migrations. It ensures the schema.rb file only reflects intended changes, preventing accidental updates from other branches before merging.
