Elixir Ecto Patterns

The elixir-ecto-patterns skill provides a curated collection of reusable database interaction patterns for Elixir applications using the Ecto ORM. It streamlines complex queries, migrations, and repository logic by offering pre-defined, battle-tested solutions common in production environments.

When to use it

• Accelerate development when implementing standard CRUD operations or advanced query filters without writing boilerplate code from scratch.
• Standardize database access patterns across a team to ensure consistency and reduce onboarding time for new Elixir developers.
• Quickly prototype complex data relationships, such as nested associations or polymorphic queries, leveraging existing community solutions.
• Refactor legacy Ecto repositories by replacing ad-hoc database logic with established, maintainable patterns.

Key capabilities

• Pre-built query macros and functions for common Ecto scenarios.
• Repository pattern implementations that separate business logic from data access.
• Migration templates and utilities for schema management.
• Association helpers to simplify linking related database tables.

Example prompts

• "Generate an Ecto repository module using the patterns from elixir-ecto-patterns for a User model with nested comments."
• "Show me how to implement a complex multi-table join query using the provided Elixir Ecto patterns library."
• "Refactor this custom database function into a standard pattern defined in the elixir-ecto-patterns collection."

Tips & gotchas

Ensure your project is already initialized with Ecto and the necessary dependencies before applying these patterns, as they rely on specific version compatibility. While these patterns cover common ground cases, always review the generated code to ensure it fits your specific business logic constraints and performance requirements.
