Overview

Enforces I18n.l(value, format: :name) instead of .strftime(...) in view files.

Hardcoded strftime patterns bypass locale-aware formatting. Use I18n.l with named formats defined in config/locales/time..yml and date..yml.

.strftime inside a value: pair is exempt: HTML datetime-local input values must follow the HTML spec, not locale display formatting.

Scope with the standard RuboCop Include/Exclude in your config:

Locallingo/StrftimeInView:
Include: [app/views/**/*.rb]
Exclude: [app/views/**/*_mailer/**/*.rb]

Examples:

# bad
@user.created_at.strftime("%B %d, %Y")

# good
I18n.l(@user.created_at, format: :long)
