Question

我正在尝试从spree 0.7升级到spree 1.0.7。成功安装捆绑后，我发现以下错误：

/config/initializers/product_review_ratings.rb

module Spree
  module ProductReviewsRatings
    class Config
      include Singleton
      include PreferenceAccess

      class << self
        def instance
          return nil unless ActiveRecord::Base.connection.tables.include?('configurations')
          ProductReviewsRatingsConfiguration.find_or_create_by_name("Default product reviews and ratings configuration")
        end
      end
    end
  end
end

我试图谷歌，但找不到任何东西

通过此提交从Spree 1.0.0中删除了PreferenceAccess： https://github.com/spree/spree/commit/a4a57db941eeb6329ac9a5de64f2175e33a56f95

您可以将preference_access.rb添加到您的应用中，以便恢复该功能，但这很可能会导致其他问题。

如果可能，您可能需要考虑从SpreeProductReviewsRatings移植到spree_reviews扩展，该扩展目前支持Spree 1.0 - 2.3.0.beta。
