// Troubleshoot common Wheels errors and provide debugging guidance. Use when encountering errors, exceptions, or unexpected behavior. Provides error analysis, common solutions, and debugging strategies for Wheels applications.
Automatically detect and prevent common Wheels framework errors before code is generated. This skill activates during ANY Wheels code generation (models, controllers, views, migrations) to validate patterns and prevent known issues. Scans for mixed arguments, query/array confusion, non-existent helpers, and database-specific SQL.
Generate RESTful API controllers with JSON responses, proper HTTP status codes, and API authentication. Use when creating API endpoints, JSON APIs, or web services. Ensures proper REST conventions and error handling.
Generate authentication system with user model, sessions controller, and password hashing. Use when implementing user authentication, login/logout, or session management. Provides secure authentication patterns and bcrypt support.
Generate Wheels MVC controllers with CRUD actions, filters, parameter verification, and proper rendering. Use when creating or modifying controllers, adding actions, implementing filters for authentication/authorization, handling form submissions, or rendering views/JSON. Ensures proper Wheels conventions and prevents common controller errors.
Configure Wheels applications for production deployment with security hardening, performance optimization, and environment-specific settings. Use when preparing for production, configuring servers, or hardening security.
Generate documentation comments, README files, and API documentation for Wheels applications. Use when documenting code, creating project READMEs, or generating API docs.

Cause: Mixed positional and named arguments
Solution: Use consistent argument style
โ hasMany("comments", dependent="delete")
โ
hasMany(name="comments", dependent="delete")
Cause: Using Array functions on queries
Solution: Use query methods
โ ArrayLen(post.comments())
โ
post.comments().recordCount
Cause: Association not properly defined or typo
Solution:
Cause: Migration not run or table name mismatch
Solution:
wheels dbmigrate latest
Cause: Property doesn't exist in database
Solution:
// In config/settings.cfm
set(showDebugInformation=true);
set(showErrorInformation=true);
<cfdump var="#post#" label="Post Object">
<cfabort>
// Wheels logs all SQL to debugging output
// Look for red SQL queries (errors)
