Rails 4：无法使用 Figaro gem 保护数据

Question

使用 twitter api 创建应用程序，我有相关代码 但是当我想使用 figaro gem 来保护时，我在输入 rake figaro:heroku 时出现错误

rake figaro:heroku
rake aborted!

keyword.rb 文件

def grab_twitts
      client = Twitter::REST::Client.new do |config|
      config.consumer_key        = "2DZcdTw4p1m2yU18xxxxxxxxx"
      config.consumer_secret     = <%= ENV["CONFIG.CONSUMER_SECRET"] %>
      config.access_token        = "71875314-xPOGuWIU7CiDcR3Vx9xxxxxxxxxxxxxxxx"
      config.access_token_secret = <%= ENV["CONFIG.ACCESS_TOKEN_SECRET"] %>
    end

安装了 figaro gem 并将以下信息添加到 application.yml

CONFIG.CONSUMER_SECRET     = "whpCvjNmePXzj6iSfxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
CONFIG.ACCESS_TOKEN_SECRET = "1P00CJmiQ7Tqhxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

删除 = 后：现在又出现错误

class Keyword < ActiveRecord::Base

    has_many :tweets

    def grab_twitts
      client = Twitter::REST::Client.new do |config|
      config.consumer_key "2DZcdTw4pvccccccccccccc"
      config.consumer_secret <%= ENV["CONFIG.CONSUMER_SECRET"] %>
      config.access_token "71875314-xPOGuWIU7CiDcR3Vx9pkJbbbbbbbbbbbbb"
      config.access_token_secret:  <%= ENV["CONFIG.ACCESS_TOKEN_SECRET"] %>
    end

    client.search(self.word, :count => 10, :result_type => "recent").take(10).collect do |tweet|
        new_tweet = Tweet.new

        new_tweet.tweet_id = tweet.id.to_s
        new_tweet.tweet_created_at = tweet.created_at
        new_tweet.text = tweet.text


        new_tweet.user_uid = tweet.user.id
        new_tweet.user_name = tweet.user.name
        new_tweet.user_screen_name = tweet.user.screen_name
        new_tweet.user_image_url = tweet.user.profile_image_url.to_s


        new_tweet.keyword = self

        new_tweet.save

        end
    end
end

Answer 1

当您从database.yml 之类的地方访问值时，您需要<%= ... %> 语法。但是当你在一个模型中时，你应该把它排除在外。试试：

client = Twitter::REST::Client.new do |config|
  config.consumer_key = "2DZcdTw4pvccccccccccccc"
  config.consumer_secret = ENV["CONFIG.CONSUMER_SECRET"]
  config.access_token = "71875314-xPOGuWIU7CiDcR3Vx9pkJbbbbbbbbbbbbb"
  config.access_token_secret = ENV["CONFIG.ACCESS_TOKEN_SECRET"]
end

Answer 2

application.yml（和一般的 YAML 文件）键值对需要像这样格式化：

CONFIG.CONSUMER_SECRET: "whpCvjNmePXzj6iSfxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
CONFIG.ACCESS_TOKEN_SECRET: "1P00CJmiQ7Tqhxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

I.E.使用 Javascript 对象表示法。你改用=，我认为这就是导致 figaro 崩溃的原因。
