CKEditor Carrierwave Cloudinary

我正在尝试让CKEditor与Carrierwave和Cloudinary一起工作。 到目前为止，具有常规文件上载字段的非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，但在本地保存文件。

这是我目前的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

这是我目前工作的ckeditor_picture_uploader.rb文件：

 # encoding: utf-8 class CkeditorPictureUploader  [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 

Answer 1

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 

Answer 2

Ckeditor已更新，因此根据ckeditor gem版本，这可能需要是extract_size和extract_dimensions

提交更改位置： https ： //github.com/galetahub/ckeditor/blob/4e6d8413cc71f40d2d58ab3d0cb8dad19dd96894/lib/ckeditor/backend/carrierwave.rb

即：

 [: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 

Answer 3

在这里查看我的评论

https://github.com/galetahub/ckeditor/issues/670#issuecomment-301218366

 # encoding: utf-8 class CkeditorPictureUploader < CarrierWave::Uploader::Base include Ckeditor::Backend::CarrierWave include CarrierWave::MiniMagick include Cloudinary::CarrierWave process :extract_dimensions [: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 version :thumb do process :resize_to_fill => [118, 100] end version :content do process :resize_to_limit => [800, 800] end def extension_white_list Ckeditor.image_file_types end end 

Answer 4

我也对这些gem的组合有疑问。 编辑您的CkeditorAttachmentFileUploader看起来类似于：

 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，因此asset.content_url将始终为nil，从而导致错误。 我这样修好了：

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

类似的Ckeditor::AttachmentFile类，如果你有它。
