Class Method Details

.normalize_name(name)

[ GitHub ]

  
# File 'actionpack/lib/action_dispatch/routing/mapper.rb', line 429

def self.normalize_name(name)
  normalize_path(name)[1..-1].tr("/", "_")
end

.normalize_path(path)

Invokes Journey::Router::Utils.normalize_path, then ensures that /(:locale) becomes (/:locale). Except for root cases, where the former is the correct one.

[ GitHub ]

  
# File 'actionpack/lib/action_dispatch/routing/mapper.rb', line 412

def self.normalize_path(path)
  path = Journey::Router::Utils.normalize_path(path)

  # the path for a root URL at this point can be something like
  # "/(/:locale)(/:platform)/(:browser)", and we would want
  # "/(:locale)(/:platform)(/:browser)"

  # reverse "/(", "/((" etc to "(/", "((/" etc
  path.gsub!(%r{/(\(+)/?}, '\1/')
  # if a path is all optional segments, change the leading "(/" back to
  # "/(" so it evaluates to "/" when interpreted with no options.
  # Unless, however, at least one secondary segment consists of a static
  # part, ex. "(/:locale)(/pages/:page)"
  path.sub!(%r{^(\(+)/}, '/\1') if %r{^(\([^)]\))(\(/:[^)]\))*$}.match?(path)
  path
