SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you implement internationalization (i18n) in Rails so your app can present the right language, pluralization, and localized formatting without scattering hardcoded strings everywhere.

Core Features & Use Cases

  • Translation structure for Rails: Organize locale files by domain (models, views, mailers, components) to keep lookups predictable and maintainable.
  • Correct lookup patterns: Use lazy view lookups (t(".key")), interpolation, and _html keys for localized dynamic content.
  • Locale-aware formatting & pluralization: Localize dates/currency, apply plural rules (including complex cases like French), and switch locales via URL or user preference.

Quick Start

Configure your Rails locale defaults and add matching translation files under config/locales/, then update your views to use t(".title") so the correct language is resolved lazily.

FAQPage Schema
How do I structure Rails i18n locale files for multilingual apps?▼

Organize Rails i18n locale files by domain—models, views, mailers, and components—under config/locales/ to keep translation lookups predictable and maintainable across multilingual apps.

What is the best way to handle Rails translation lookup patterns for views and components?▼

Use Rails I18n lazy lookups like `t(".title")` in views and components to resolve the correct language automatically based on the template path, avoiding hardcoded strings.

How do I handle complex pluralization and date formatting in Rails locales?▼

Handle Rails pluralization and date formatting by applying locale-specific plural rules, including complex cases like French, and localizing dates and currencies using YAML-based locale configuration.

Does this Rails i18n approach work with i18n-tasks for testing and maintenance?▼

Yes, this Rails i18n approach satisfies requirements for i18n-tasks driven testing and maintenance, validating that translation keys, interpolation, and locale organization remain consistent across the application.

When do I need to use interpolation and _html keys for localized dynamic content in Rails?▼

Use interpolation and `_html` keys in Rails when localized dynamic content requires variable substitution or safe HTML rendering, ensuring translations handle dynamic data without breaking multilingual display.
