ruby-on-rails - undefined method `cookie_value' for .... Impressionist gem

Question

我已经设置了 impressionist gem在我的电影模型中。它一直运行良好，更新了展示次数，但在尝试获取 Films#Show 页面时突然收到以下错误。

undefined method `cookie_value' for "60cb104e4befe185a8b81aac9a2c5e3c":String

好像和session_hash有关系，但是不知道怎么解决。

有没有人有什么想法？

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

电影放映页面

<%= render "shared/ticker" %>




<div class="back-to-films">
  <%= link_to films_path do %>
  <span><%= image_tag "BackArrow1.svg" %> </span><h3 class="back-to-gallery">Back to film gallery</h3>

</div>

Answer 1

我将使用 impression gem 的遗留 Rails 应用程序更新到版本 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它:

gem 'impressionist',
  git: 'git@github.com:charlotte-ruby/impressionist.git',
  ref: '46a582ff8cd3496da64f174b30b91f9d97e86643'

原因是 fix因为异常不在他们的最新版本 (2.0.0) 中，而是在其 master 分支中。
