SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires quo, literal, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps you build and manage complex queries for databases and collections, saving you time and reducing errors through its composable and type-safe query objects.

Core Features & Use Cases

Composable Queries: Build queries from smaller, reusable components.
Type Safety: Use Literal to ensure query properties are defined and validated at compile time.
Pagination: Implement built-in pagination for efficient data retrieval.
Transformations: Apply transformations to query results for custom presentation or manipulation.
Use Case: Suppose you have a Rails application with a Post model and you want to fetch all unread posts from the last week and display them with additional information. The Quo Skill would allow you to define a query object that encapsulates this logic, making the code clean and easy to maintain.

Quick Start

Use the Quo skill to define and execute a query for fetching posts from the last 7 days.

FAQPage Schema

How do I build composable database queries in Rails?▼

Composable database queries in Rails are built by defining reusable query objects with type-safe properties. This approach encapsulates complex query logic into smaller, maintainable components using a fluent API.

How does type safety work with Rails database queries?▼

Type safety for Rails database queries works by validating query properties at compile time using the Literal gem. This ensures defined query parameters are checked before execution, reducing runtime errors.

What's the best way to organize reusable query logic for collections?▼

The best way to organize reusable collection query logic is encapsulating it within dedicated query objects. This makes the query code testable, composable, and easy to maintain across your application.

Can I paginate and transform database query results in Ruby?▼

Yes, you can paginate and transform database query results by applying built-in pagination methods and custom transformations. This allows efficient data retrieval and tailored presentation of the fetched collection.

Do I need the Literal gem to use type-safe query objects?▼

Yes, you need the Literal gem alongside the Quo gem to use type-safe query objects. Literal provides the compile-time property validation required for the query definitions to function correctly.

When should I use query objects instead of standard Rails scopes?▼

You should use query objects instead of standard Rails scopes when your database queries become complex and require type safety. Query objects offer better composability, testability, and transformations for collections.
