Rails-I18nLocaleAssignment.md

Pattern: Use of I18n.locale=

Issue: -

Description

Checks for the use of I18n.locale= method.

The locale attribute persists for the rest of the Ruby runtime, potentially causing unexpected behavior at a later time. Using I18n.with_locale ensures the code passed in the block is the only place I18n.locale is affected. It eliminates the possibility of a locale sticking around longer than intended.

Examples

# bad
I18n.locale = :fr

# good
I18n.with_locale(:fr) do
end
