ruby-on-rails - Rails API，Cloudinary：未初始化的常量 CLOUDINARY_CLOUD_NAME (NameError)

问题描述

我一直在我的 Rails API 中上传和删除 Cloudinary 上的图像，直到我开始收到主题错误。我无法启动并运行服务器。

任何想法是什么原因造成的？

我安装了 cloudinary gem，并在 config/initializers/cloudinary.rb 中有我的配置，我的凭据在 application.yml 中：

Cloudinary.config do |config|
  config.cloud_name = ENV[CLOUDINARY_CLOUD_NAME]
  config.api_key = ENV[CLOUDINARY_API_KEY]
  config.api_secret =  ENV[CLOUDINARY_API_SECRET]
  config.secure = true
  config.cdn_subdomain = true
end

我在我的图像控制器中引用 Cloudinary，如下所示：

result = Cloudinary::Uploader.upload(image, options = {})

这是完整的错误：

*** 作为更新，我将 cloudinary url 放在了我的 application.yml 中并注释掉了 cloudinary.rb，它现在可以工作了，但是如果有人能解释为什么会出现未初始化的常量错误，我将不胜感激。****

解决方案

从共享的规范看来，您没有指定环境变量，而是将变量作为常量提及。

将代码更改为以下提到的：

Cloudinary.config do |config|
  config.cloud_name = ENV["CLOUDINARY_CLOUD_NAME"]
  config.api_key = ENV["CLOUDINARY_API_KEY"]
  config.api_secret =  ENV["CLOUDINARY_API_SECRET"]
  config.secure = true
  config.cdn_subdomain = true
end
