📝 Walkthrough

Walkthrough

The pull request refactors I18n locale fallback and pluralization handling. Static environment configurations setting config.i18n.fallbacks are removed and replaced with a custom FallbackLocaleList class in the i18n initializer that dynamically determines fallback order using site settings. Pluralization backend setup is consolidated into the i18n initializer, and a runtime ensure_loaded! method is added to guarantee locale data availability.

Changes

Cohort / File(s)	Summary
Environment Configuration Removals config/environments/production.rb, config/environments/profile.rb, config/cloud/cloud66/files/production.rb	Removed static config.i18n.fallbacks = true configuration and related comments from all three environment files.
I18n Initialization Refactoring config/initializers/i18n.rb, config/initializers/pluralization.rb	Moved I18n::Backend::Pluralization integration from pluralization.rb into i18n.rb. Introduced new FallbackLocaleList class that provides dynamic fallback order based on locale and SiteSetting.default_locale. Set I18n.fallbacks to instance of FallbackLocaleList and added I18n::Backend::Fallbacks support.
Runtime Locale Loading lib/freedom_patches/translate_accelerator.rb, app/controllers/application_controller.rb	Added ensure_loaded!(locale) singleton method to I18n::Backend for explicit locale initialization. Controller's set_locale method now calls I18n.fallbacks.ensure_loaded! after determining locale to ensure fallback data is loaded at runtime.

Poem

🐰 whiskers twitching with joy

Locales now load with care,
FallbackLists float through the air,
No config stuck in static place,
Runtime calls set the pace! 🌍✨

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The PR title 'Automated Test: localization-system-post' is vague and does not meaningfully describe the actual changes. While it references 'localization-system', the substantial refactoring involves moving I18n fallback and pluralization configuration from environment files to initializers, plus adding a custom fallback locale strategy.	Replace with a more specific title describing the core change, such as 'Refactor I18n fallbacks and pluralization initialization' or 'Move I18n configuration to custom initializers with runtime fallback loading'.
