ruby-on-rails - 从 Heroku 迁移到专用服务器后，rails 生成蜻蜓为 #

Question

站点已从 Heroku 迁移到专用的 Ubuntu 服务器，迁移站点正常工作后，除了托管在 S3 上的图像。

加载带有图像的页面时，将返回以下类型的错误:

Completed 200 OK in 1428.8ms (Views: 505.5ms | ActiveRecord: 322.2ms)

Dragonfly::Configurable::NotConfigured (You need to configure Dragonfly::DataStorage::S3DataStore with bucket_name):

我可以看到该应用程序没有在 gemfile 中列出蜻蜓，因为 Heroku 似乎做的事情有点不同，并且已经重新安装了蜻蜓，但是当尝试生成配置文件时返回以下错误。

Recaptcha 本身似乎工作正常，并且 bundle install 没有返回任何错误，但我无法让蜻蜓工作。

recaptcha.rb 看起来像这样

Recaptcha.configure do |config|
  config.public_key  = 'public key'
  config.private_key = 'private key'
  config.api_version = 'v2'
end

我创建了不存在的 .env 文件，内容如下:

export RECAPTCHA_PUBLIC_KEY = 'public key'
export RECAPTCHA_PRIVATE_KEY = 'private key'

我还尝试手动添加到 config/environments/production.rb 和 config/environments/development.rb 如下:

recaptcha_public_key= "[PUBLIC KEY]"
recaptcha_private_key= "[PRIVATE KEY]"

我不确定我在这里缺少什么，从 Heroku 迁移到独立的 Linux 系统后，是否有人对蜻蜓和 recaptcha 有任何经验

Answer 1

他们在版本 4 中更改了 API，因此如果您通过 gemfile 安装它而不指定版本并且默认为版本 4，则需要在配置中进行更改。

从他们的 CHANGELOG.md :

4.0.0 - 2016-11-14

public_key -> site_key and private_key -> secret_key

更改您的 config/initializers/recaptcha.rb对此:

Recaptcha.configure do |config|
  config.site_key  = 'public key'
  config.secret_key = 'private key'
  ...
