目前，我们公司在cloud66上托管了我们公司的工作生产版本。我经历了设置所有环境变量并使我们的清单符合鼻烟。现在，除了我们的API密钥，登台是生产的精确复制品。我们的production.rb文件与sour staging.rb文件相同：
#staging.rb
Rails.application.configure do
# Settings specified here will take precedence over those in config/application.rb.
# Code is not reloaded between requests.
config.cache_classes = true
# Eager load code on boot. This eager loads most of Rails and
# your application in memory, allowing both threaded web servers
# and those relying on copy on write to perform better.
# Rake tasks automatically ignore this option for performance.
config.eager_load = true
# Full error reports are disabled and caching is turned on.
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
# Disable serving static files from the `/public` folder by default since
# Apache or NGINX already handles this.
config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
# Compress JavaScripts and CSS.
config.assets.js_compressor = :uglifier
# config.assets.css_compressor = :sass
# Do not fallback to assets pipeline if a precompiled asset is missed.
config.assets.compile = false
# Mailer
ActionMailer::Base.smtp_settings = {
:address => "smtp.sendgrid.net",

}
# Mailer for Devise
config.action_mailer.default_url_options = { host: ENV['FULL_URL'] }
# `config.assets.precompile` and `config.assets.version` have moved to config/initializers/assets.rb
# Enable serving of images, stylesheets, and JavaScripts from an asset server.

# Specifies the header that your server uses for sending files.
# config.action_dispatch.x_sendfile_header = 'X-Sendfile' # for Apache

# config.action_cable.allowed_request_origins = [ 'http://example.com', /http:\/\/example.*/ ]
# Force all access to the app over SSL, use Strict-Transport-Security, and use secure cookies.
config.force_ssl = true
# Use the lowest log level to ensure availability of diagnostic information
# when problems arise.
config.log_level = :debug
# Prepend all log lines with the following tags.
config.log_tags = [ :request_id ]
# Use a different cache store in production.

# Use a real queuing backend for Active Job (and separate queues per environment)
# config.active_job.queue_adapter = :resque
# config.active_job.queue_name_prefix = "gathrly_#{Rails.env}"
config.action_mailer.perform_caching = false
# Ignore bad email addresses and do not raise email delivery errors.
# Set this to true and configure the email server for immediate delivery to raise delivery errors.
# config.action_mailer.raise_delivery_errors = false
# Enable locale fallbacks for I18n (makes lookups for any locale fall back to
# the I18n.default_locale when a translation cannot be found).
config.i18n.fallbacks = true
# Send deprecation notices to registered listeners.
config.active_support.deprecation = :notify
# Use default logging formatter so that PID and timestamp are not suppressed.
config.log_formatter = ::Logger::Formatter.new
# Use a different logger for distributed setups.
# require 'syslog/logger'
# config.logger = ActiveSupport::TaggedLogging.new(Syslog::Logger.new 'app-name')
if ENV["RAILS_LOG_TO_STDOUT"].present?
logger = ActiveSupport::Logger.new(STDOUT)
logger.formatter = config.log_formatter
config.logger = ActiveSupport::TaggedLogging.new(logger)
end
# Do not dump schema after migrations.
config.active_record.dump_schema_after_migration = false
end
我将暂存设置添加到我们的c66清单文件中，这也是生产的精确副本：
# C66 manifest file
production:
postgresql:
configuration:
version: 9.6.1
postgis: false
staging:
postgresql:
configuration:
version: 9.6.1
postgis: false
部署失败，日志指向Devise：

所以，我正在查看devise.rb文件，我看到这个注释掉的代码：
# The secret key used by Devise. Devise uses this key to generate
# random tokens. Changing this key will render invalid all existing
# confirmation, reset password and unlock tokens in the database.
# Devise will use the `secret_key_base` as its `secret_key`
# by default. You can change it below and use your own secret key.
# config.secret_key = 'somekey' # Real key removed for security.
我对这段代码知之甚少。我认为，因为所有内容都是生产的精确复制品，所以我们也应该为我们的暂存环境注释掉它。我不知道取消注释config.secret_key的含义以及可能对我们的生产环境有什么影响。
有人可以解释为什么它在生产中有效，但是在其他设置中的分段失败了吗？
答案 0 :(得分：2)
我发现了这个问题。我忘了将登台信息添加到设置了secret_key_base的secrets.yml。
