Rails: секретный маркер ошибки

Question

Я использую Rails 3.2.13 и получить следующее сообщение:

ArgumentError (A secret is required to generate an integrity hash for cookie session data. Use config.secret_token = "some secret phrase of at least 30 characters"in config/initializers/secret_token.rb): 

Я нашел ссылку на это this pull request и обсуждение here.

Я использую Devise (следовательно, Warden), и информация в обсуждении актуальна. Я бы предпочел не взламывать драгоценный камень railtie - что здесь рекомендуется?

Благодаря

Answer 1

В моих config/initializers/secret_token.rb я следующий

# Be sure to restart your server when you modify this file. 

# Your secret key for verifying the integrity of signed cookies. 
# If you change this key, all old signed cookies will become invalid! 
# Make sure the secret is at least 30 characters and all random, 
# no regular words or you'll be exposed to dictionary attacks. 
Friendflat::Application.config.secret_token = 'asdf...' 

Вы должны добавить то же, настраиваемое значение до некоторой случайной длиной шестнадцатеричной строки.
