ruby-on-rails - Ruby on Rails bootsy + cloudinary 上传图片麻烦

Question

我有 RoR 项目，生活在 heroku 上。我有 bootsy (具有图像上传功能的编辑器)，我有 cloudinary。我已经设置了 uploader 、cloudinary api key 和初始化程序(如果需要，可以向您展示)。现在，当我尝试在 bootsy 中上传图像时 - 它会创建数据库行，并在 cloudinary 中创建图像。但是在 bootsy 的 js 窗口中，有空 <img>

ruby '2.3.1'
gem 'rails', '~> 5.1.1'
gem 'bootsy'
gem 'carrierwave'
gem 'fog'
gem 'cloudinary', '~> 1.8.1'

1) uploaders/bootsy/image_uploader.rb

module Bootsy
  class ImageUploader < CarrierWave::Uploader::Base
    include CarrierWave::MiniMagick

    # storage Bootsy.storage

    include Cloudinary::CarrierWave

    def store_dir
      "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
    end

    version :large do
      process :eager => true
      process resize_to_fit: [
                  700, 700
              ]

    end

    version :medium do
      process :eager => true
      process resize_to_fit: [
                  300, 300
              ]
    end

    version :small do
      process :eager => true
      process resize_to_fit: [
                  150, 150
              ]
    end

    version :thumb do
      process :eager => true
      process resize_to_fit: [
                  150, 150
              ]
    end


    def extension_white_list
      %w(jpg jpeg gif png)
    end
  end
end

2) 初始化器/bootsy.rb

Bootsy.setup do |config|
  config.image_versions_available = [:small, :medium, :large, :original]
  config.storage = :fog
end

3) models/article.rb

class Article < ApplicationRecord
  include Bootsy::Container
  mount_uploader :image, Bootsy::ImageUploader

  mount_uploader :main_image, ArticleImageUploader
  mount_uploader :list_image, ArticleImageUploader

end

P.S 好吧，我真的不知道 - 我只是在公共(public)存储库中重复这个错误。 https://bitbucket.org/dekakisalove/bootsy_tes/我会尽快为这个问题添加悬赏。

此问题是由于方法 store! 的返回值不正确造成的类Cloudinary::CarrierWave::Storage

要解决此问题，您可以使用多种变体，例如:

像这样 config/initializers/cloudinary_store.rb

module CloudinaryStorage
  def store!(file)
    super || uploader.metadata
  end
end

ActiveSupport.on_load :after_initialize do
  Cloudinary::CarrierWave::Storage.prepend CloudinaryStorage
end

或者像 app/uploaders/image_uploader.rb 中这样

module Bootsy
  class ImageUploader < CarrierWave::Uploader::Base
    after :store, :reload_data

    def reload_data(file)
      model.reload
    end
    # etc..
