rails generate dragonfly从Heroku迁移到专用服务器后返回未定义的方法`public_key ='for#<Recaptcha

Question

站点已从Heroku迁移到专用的Ubuntu服务器,并且在迁移站点正常工作之后,除了在S3上托管的映像之外.

当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)
Started GET "/system/images/W1siZiIsIjIwMTYvMDkvMjIvMTMvMjQvMjUvMjE1L05hb21pX1NhbnNvbS5qcGciXSxbInAiLCJ0aHVtYiIsIjM2MHgzNjAjIl1d/picture.jpg" for ip at 2016-11-23 00:27:24 +0000

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

我可以看到应用程序没有在gemfile中列出蜻蜓,因为Heroku似乎做了一些不同的事情,并重新安装了蜻蜓,但是当试图生成配置文件后,返回错误.

Recaptcha本身似乎工作正常,捆绑安装没有返回任何错误,但我不能让蜻蜓工作.

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系统之后,是否有任何人有使用dragonfly和recaptcha的经验

Answer 1

他们使用版本4更改了API,因此如果您通过gemfile安装它而未指定版本且默认为版本4,则需要在配置中进行更改.

来自他们的CHANGELOG.md:

4.0.0 - 2016-11-14

public_key -> site_key and private_key -> secret_key

把你config/initializers/recaptcha.rb改成这个:

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