我正在尝试让 CKEditor 与 Carrierwave 和 Cloudinary 一起工作。到目前为止，具有常规文件上传字段的非 CKEditor 启用视图与 Carrierwave 和 Cloudinary 完美配合。但是，当我尝试在 CKEditor 中上传文件并“将其发送到服务器”时，我得到了一个NoMethodError - undefined method 'each' for "image/jpeg":String:

在从 CKEditor 类中删除本地存储配置之前，它正在工作，但将文件保存在本地。

这是我当前的 CKEditor 上传器：

class CkeditorAttachmentFileUploader < CarrierWave::Uploader::Base
  include Cloudinary::CarrierWave
  include Ckeditor::Backend::CarrierWave

  def extension_white_list
    Ckeditor.attachment_file_types
  end
end

任何想法表示赞赏！

更新 - 来自 Tal Lev-Ami 答案的工作配置

这是我当前的工作ckeditor_picture_uploader.rb文件：

# encoding: utf-8
class CkeditorPictureUploader < CarrierWave::Uploader::Base
  include Ckeditor::Backend::CarrierWave
  include Cloudinary::CarrierWave

  # Include RMagick or ImageScience support:
  # include CarrierWave::RMagick
  include CarrierWave::MiniMagick
  # include CarrierWave::ImageScience

  # Choose what kind of storage to use for this uploader:
  # storage :file

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  # def store_dir
  #   "uploads/ckeditor/pictures/#{model.id}"
  # end

  # Provide a default URL as a default if there hasn't been a file uploaded:
  # def default_url
  #   "/images/fallback/" + [version_name, "default.png"].compact.join('_')
  # end

  # Process files as they are uploaded:
  # process :scale => [200, 300]
  #
  # def scale(width, height)
  #   # do something
  # end

  [:extract_content_type, :set_size, :read_dimensions].each do |method|
    define_method :"#{method}_with_cloudinary" do
      send(:"#{method}_without_cloudinary") if self.file.is_a?(CarrierWave::SanitizedFile)
      {}
    end
    alias_method_chain method, :cloudinary
  end

  process :read_dimensions

  # Create different versions of your uploaded files:
  version :thumb do
    process :resize_to_fill => [118, 100]
  end

  version :content do
    process :resize_to_limit => [800, 800]
  end

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:
  def extension_white_list
    Ckeditor.image_file_types
  end
end

尝试将以下代码添加到您的 CkPictureUploader/CkeditorAttachmentFileUploader：

[:extract_content_type, :extract_size, :extract_dimensions].each do |method|
  define_method :"#{method}_with_cloudinary" do
    send(:"#{method}_without_cloudinary") if self.file.is_a?(CarrierWave::SanitizedFile)
    {}
  end
  alias_method_chain method, :cloudinary
end

ckeditor 已更新，因此这可能需要为 extract_size 和 extract_dimensions 取决于 ckeditor gem 版本

提交更改的地方： https ://github.com/galetahub/ckeditor/blob/4e6d8413cc71f40d2d58ab3d0cb8dad19dd96894/lib/ckeditor/backend/carrierwave.rb

IE：

[:extract_content_type, :extract_size, :extract_dimensions].each do |method|
  define_method :"#{method}_with_cloudinary" do
  send(:"#{method}_without_cloudinary") if self.file.is_a?  (CarrierWave::SanitizedFile)
    {}
 end
  alias_method_chain method, :cloudinary
end

我对这些宝石的组合也有疑问。编辑您CkeditorAttachmentFileUploader的外观与此类似：

class CkeditorAttachmentFileUploader < CarrierWave::Uploader::Base
  include Ckeditor::Backend::CarrierWave
  include Cloudinary::CarrierWave

  [:extract_content_type, :extract_size, :extract_dimensions].each do |method|
    define_method :"#{method}_with_cloudinary" do
      send(:"#{method}_without_cloudinary") if self.file.is_a?(CarrierWave::SanitizedFile)
      {}
    end
    alias_method :"#{method}_without_cloudinary", method
    alias_method method, :"#{method}_with_cloudinary"
  end

  def extension_white_list
    Ckeditor.attachment_file_types
  end
end

之后，您会发现另一个错误。我发现在Ckeditor::AssetResponse#asset_url 方法中，asset对象没有重新加载，所以asset.content_url总是 nil 从而导致错误。我这样修复它：

class Ckeditor::Picture < Ckeditor::Asset
  ...
  def url_content
    url(:content) || begin
      if persisted?
        reload
        url(:content)
      end
    end
  end
end

Ckeditor::AttachmentFile如果你有它，同样适用于课堂。
