Ruby on rails 未定义的方法“cookie”值'；对于印象派宝石

我已经在我的电影模型中设置了。它一直运行良好，更新了印象计数，但在尝试获取电影放映页面时，我突然收到了以下错误

“60CB104E4BEE185A8B81AAC9A2C5E3C”的未定义方法“cookie_值”：字符串

它似乎与session_散列有关，但不确定如何解决这个问题

有人有什么想法吗

这是我的电影模型：

    class Film < ApplicationRecord


  acts_as_votable
  is_impressionable

  mount_uploader :cover, ImageUploader
  mount_uploader :video, VideoUploader
  mount_uploader :trailer, VideoUploader



   def score
    self.get_upvotes.size - self.get_downvotes.size
  end

  extend FriendlyId
  friendly_id :title, use: :slugged

  # one film has many reviews
  has_many :reviews, dependent: :destroy

  validates :title, presence: true
  validates :author, presence: true
  validates :cover, presence: true
  validates :description, presence: true

end

我将一个使用

impression

gem的遗留Rails应用程序更新为版本6，并遇到了相同的异常。我通过在

Gemfile

中为

impression

gem指定一个特定的提交来解决这个问题：

gem‘印象派’，
吉特：'git@github.com：夏洛特·鲁比/印象派.git'，
参考：“46a582ff8cd3496da64f174b30b91f9d97e86643”

---

这是因为异常的原因不在其最新版本（2.0.0）中，而是在其主分支中。

Jules，非常感谢！你的回答解决了这个问题。只是好奇，你是如何发现这个补丁在主分支中的？我将gem转移到本地开发环境并开始调试。当我无法在

master

上重现问题时，我查看了

app/controllers/impressive\u controller.rb

的提交历史记录，发现修复程序尚未发布。Jules，通过在Gemfile中指定此提交，您成功部署了吗？我刚刚尝试部署到Heroku，在构建过程中，它无法访问印象派git—说“主机密钥验证失败—无法从远程存储库读取”@AaronZ我刚才使用上面的代码片段成功地部署到Heroku。虽然我没有部署问题，但我希望替换此gem以避免将来出现问题，因为此gem不再维护。当我尝试为部署构建时，我在构建日志中收到错误：

从中获取gem元数据https://rubygems.org/............        吸引git@github.com：charlotte ruby/impressionist.git主机密钥验证失败。致命：无法从远程存储库读取。请确保您具有正确的访问权限，并且存储库存在。

您没有这些错误吗？您是否已将此gem克隆并提交到您自己的本地环境中？谢谢你的信息！
