Fix for setting a he locale (/he prefix) to named routes. Bug was that #url_for called from views didn't get the correct locale. Solved by set_locale if @locale.nil in #default_url_options

gistfile1.rb

def set_locale
  if @locale.nil?
    I18n.locale = params[:locale] || I18n.default_locale
    @locale     = I18n.locale.to_sym
  end
end
  
def default_url_options(options = {})
  set_locale if @locale.nil?
  
  if [:he].include? @locale
    options.reverse_merge locale: @locale
  else
    options
  end
end
