debug:rails

Debug Rails routing and ActiveRecord errors by following a structured workflow: reproduce the issue, gather information, form hypotheses, and verify fixes using tools like rails routes, rails console, and byebug.

Detect and resolve N+1 queries in ActiveRecord by using the Bullet gem to identify inefficient data access patterns, then applying eager loading optimizations during your hypothesis testing phase.

Troubleshoot ActionController::RoutingError by running the rails routes command to inspect defined path mappings, verifying controller actions, and isolating mismatches within your Rails application routes.

Rails CSRF token failures occur when session tokens mismatch form submissions; debug by inspecting middleware configurations, verifying token generation, and checking cross-origin request headers.

Yes, use Byebug to inspect runtime states during migration conflicts and Better Errors to visualize asset pipeline failures, applying iterative fixes within your Rails environment to resolve root causes.

When standard Rails debugging tools fail, isolate the issue by reproducing the error in a clean environment, checking middleware configurations, and verifying that Byebug and Bullet dependencies are loaded correctly.
