Devise Secret Key was not set
提问by
I am developing a Rails 4 app using the Active Admin gem for the administration back end. Active Admin in turn uses Devise for user authentication. Now, when I try to deploy the app using capistranoon the VPS server, I get the below error:
我正在使用 Active Admin gem 为管理后端开发 Rails 4 应用程序。Active Admin 反过来使用 Devise 进行用户身份验证。现在，当我尝试capistrano在 VPS 服务器上部署应用程序时，出现以下错误：
rake aborted!
Devise.secret_key was not set. Please add the following to your Devise initializer:
config.secret_key = '-- secret key --'
A Google search does not do much for this error. Any suggestions why it is throwing an error? Should I add the secret key to deviseinitializer, as I cannot find any place to set such config key in initializers/devise.rb?
谷歌搜索对这个错误没有多大作用。任何建议为什么会抛出错误？我是否应该将密钥添加到devise初始化程序，因为我找不到任何地方可以设置这样的配置密钥initializers/devise.rb？

What worked for me on Rails 4.1 and Devise 3.2.4 is in config/initializers/devise.rb:
在 Rails 4.1 和 Devise 3.2.4 上对我有用的是config/initializers/devise.rb：
config.secret_key = ENV['DEVISE_SECRET_KEY'] if Rails.env.production?

As of Devise 3.2.3for Rails 4+ applications the key setting location defaults to YourAppName::Application.config.secret_key_basefound in config/initializers/secret_token.rb
作为设计3.2.3为Rails 4+应用的关键位置设置默认为YourAppName :: Application.config.secret_key_base发现，在配置/初始化/ secret_token.rb

This solved my problem:
这解决了我的问题：
Add the code below to your config/initializers/devise.rbfile.
将下面的代码添加到您的config/initializers/devise.rb文件中。
config.secret_key = '-- secret key --'
Replace '-- secret key--' with your own key. I recommend storing it in an ENV variable for security purpose.
将“--密钥--”替换为您自己的密钥。为了安全起见，我建议将其存储在 ENV 变量中。

As per changelog:
根据变更日志：
Devise will use the secret_key_base on Rails 4+ applications as its secret_key. You can change this and use your own secret by changing the devise.rb initializer.
Devise 将在 Rails 4+ 应用程序上使用 secret_key_base 作为其 secret_key。您可以通过更改 devise.rb 初始值设定项来更改此设置并使用您自己的秘密。
I went to config/secrets.ymland changed the productionvalue.
我去config/secrets.yml改变了production价值。
Before:
前：
production:
secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>
After:
后：
production:
secret_key_base: string of charaters
Of course, that should be set to the environment variable, which I will set later, but this at least got it running. I got my string by using bundle exec rake secret.
当然，这应该设置为环境变量，我稍后会设置，但这至少让它运行了。我通过使用得到了我的字符串bundle exec rake secret。

In config/initializers/devise.rbI put:
在config/initializers/devise.rb我提出：
config.secret_key = ENV["SECRET_KEY_BASE"] if Rails.env.production?
Because if you put:
因为如果你把：
$ heroku config
You'll see a secret_key_basefor the mode production.
您会看到secret_key_basemode production。

Could it be, that you did not run rails g devise:install?
难道，你没有跑rails g devise:install？
Running rails generate devise Userwithout the previous command does cause this problem.
在rails generate devise User没有上一个命令的情况下运行确实会导致此问题。

I solve my initializer problem with this ugly approach:
我用这种丑陋的方法解决了我的初始化问题：
config.secret_key = 'some1234keyq23' if Rails.env == 'production'
in config/initializers/devise.rb It now works in production as well as in development !
在 config/initializers/devise.rb 它现在可以在生产和开发中使用！

I cloned my repository onto a new machine from git. The
我从 git 将我的存储库克隆到一台新机器上。这
config/secrets.yml
file was on my .gitignore list, so that file didn't exist, and Devise doesn't create the file.
文件在我的 .gitignore 列表中，因此该文件不存在，并且 Devise 不会创建该文件。
I added the file, then re-ran
我添加了文件，然后重新运行
rails generate devise MODEL
and it worked.
它奏效了。

Check if your config\initializers\secret_token.rbhas:
检查您config\initializers\secret_token.rb是否有：
YourAppName::Application.config.secret_token
It should be:
它应该是：
YourAppName::Application.config.secret_key_base
