Ruby on Rails issues we fix before deploying
Common Ruby on Rails problems that affect Replit Deployments 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.
Replit Deployments deployment issues we check for
Common Replit Deployments problems that break Ruby on Rails apps in production.
Development server used in production
AI tools configure Replit to run the dev server (next dev, vite dev) in production instead of building and serving optimized output, wasting resources and exposing debug features.
Secrets exposed in .replit or replit.nix
API keys and database credentials end up in version-controlled configuration files instead of Replit's Secrets manager, visible to anyone who forks the project.
Reserved VM resources insufficient for workload
Replit's reserved VM allocations have fixed CPU and RAM limits. AI-generated apps with heavy processing or multiple services exceed these limits and get throttled.
Outbound networking blocked on free tier
Free Replit deployments restrict outbound network requests, breaking API calls to external services that AI-generated backends depend on.
