Overview

Checks for places where I18n "lazy" lookup can be used.

This cop has two different enforcement modes. When the EnforcedStyle is lazy (the default), explicit lookups are added as offenses.

When the EnforcedStyle is explicit then lazy lookups are added as offenses.

Examples:

EnforcedStyle: lazy (default)

# en.yml
# en:
#   books:
#     create:
#       success: Book created!

# bad
class BooksController < ApplicationController
  def create
    # ...
    redirect_to books_url, notice: t('books.create.success')
  end
end

# good
class BooksController < ApplicationController
  def create
    # ...
    redirect_to books_url, notice: t('.success')
  end
end

EnforcedStyle: explicit

# bad
class BooksController < ApplicationController
  def create
    # ...
    redirect_to books_url, notice: t('.success')
  end
end

# good
class BooksController < ApplicationController
  def create
    # ...
    redirect_to books_url, notice: t('books.create.success')
  end
end
