.... 印象派宝石的未定义方法“cookie_value”

Question

我已经设置了印象派宝石。它一直工作正常，正在更新展示次数，但在尝试获取 Films#Show 页面时突然收到以下错误。

“60cb104e4befe185a8b81aac9a2c5e3c”的未定义方法“cookie_value\”：字符串

\n

\n

似乎与 session_hash 有关，但不知道如何解决这个问题。

\n

有人有什么想法吗？

这是我的电影模型：

\n

    class Film < ApplicationRecord\n\n\n  acts_as_votable\n  is_impressionable\n\n  mount_uploader :cover, ImageUploader\n  mount_uploader :video, VideoUploader\n  mount_uploader :trailer, VideoUploader\n\n\n\n   def score\n    self.get_upvotes.size - self.get_downvotes.size\n  end\n\n  extend FriendlyId\n  friendly_id :title, use: :slugged\n\n  # one film has many reviews\n  has_many :reviews, dependent: :destroy\n\n  validates :title, presence: true\n  validates :author, presence: true\n  validates :cover, presence: true\n  validates :description, presence: true\n\nend\n

Answer 1

我将使用impressiongem 的旧版 Rails 应用程序更新到版本 6，并遇到了相同的异常。impression我通过在以下位置指定 gem 的特定提交来解决这个问题Gemfile：

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

原因是该异常的修复不在其最新版本（2.0.0）中，而是在其 master 分支中。
