Ruby on Rails issues we fix before deploying
Common Ruby on Rails problems that affect Cloudflare Pages 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.
Cloudflare Pages deployment issues we check for
Common Cloudflare Pages problems that break Ruby on Rails apps in production.
Workers runtime missing Node.js APIs
AI-generated server code uses Node.js built-ins (Buffer, fs, crypto) that don't exist in the Cloudflare Workers runtime, causing build or runtime errors.
Function invocation limits exceeded
Free tier allows 100,000 function invocations per day. AI-generated SPAs that use functions for every API call burn through limits quickly in production.
KV namespace not bound in wrangler.toml
AI tools reference KV storage in code but forget to declare the KV namespace binding in wrangler.toml, causing undefined binding errors at runtime.
Request body size limited to 100MB
Cloudflare Workers have a strict 100MB request body limit. AI-generated file upload handlers don't implement chunked uploads, failing on larger files.
