Ruby on Rails issues we fix before deploying
Common Ruby on Rails problems that affect Vercel deployments.
Mass assignment vulnerabilities
AI-generated Rails controllers that use permit! or don't properly whitelist params, allowing attackers to modify any database column including admin flags and passwords.
Missing authorization checks
Controllers that authenticate users but don't check authorization — a logged-in user can access or modify any other user's data by changing the ID in the URL.
N+1 query problems
ActiveRecord code that loads associated records in loops without includes, eager_load, or preload — causing hundreds of database queries on pages with lists.
Unsafe use of raw SQL
AI tools sometimes generate raw SQL with string interpolation instead of using ActiveRecord's parameterized query methods, enabling SQL injection attacks.
Vercel deployment issues we check for
Common Vercel problems that break Ruby on Rails apps in production.
Serverless function size exceeds 50MB limit
AI tools bundle heavy dependencies into API routes without tree-shaking, pushing serverless functions past Vercel's 50MB compressed size limit and failing the build.
Edge runtime incompatible with Node.js APIs
Generated code uses fs, crypto, or other Node.js built-ins inside Edge Runtime routes, causing deployment failures since Edge only supports a subset of Web APIs.
ISR revalidation not triggering correctly
Incremental Static Regeneration configured with stale revalidate values or missing on-demand revalidation hooks, serving outdated content indefinitely.
Environment variables missing in production
Secrets added to .env.local but not configured in the Vercel dashboard, causing runtime crashes only in production while working perfectly in local dev.
