我正在尝试让CKEditor与Carrierwave和Cloudinary一起工作。到目前为止,带有常规文件上传域的未启用CKEditor的视图可以与Carrierwave和Cloudinary完美地协同工作。但是,当我尝试在CKEditor中上传一个文件并“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。
这里是我当前的CKEditor上传程序:
class CkeditorAttachmentFileUploader < CarrierWave::Uploader::Base
include Cloudinary::CarrierWave
include Ckeditor::Backend::CarrierWave
def extension_white_list
Ckeditor.attachment_file_types
end
end

更新-来自Tal Lev-Ami answer的工作配置
这是我当前正在工作的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

end
# Add a white list of extensions which are allowed to be uploaded.

尝试将以下代码添加到CkPictureUploader/CkeditorAttachmentFileUploader:中
[: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,因此根据ckeditor gem版本的不同,可能需要extract_size和extract_dimensions
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

我对这些宝石的组合也有问题。编辑您的CkeditorAttachmentFileUploader
,使其如下所示:
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
在那之后,你会发现另一个错误。我发现在Ckeditor::AssetResponse#asset_url方法中,asset
对象不会重新加载,因此asset.content_url
将始终为空,从而导致错误。我是这样修复的:
class Ckeditor::Picture < Ckeditor::Asset
...
def url_content
url(:content) || begin
if persisted?
reload
url(:content)
end
end
end
end
如果你有Ckeditor::AttachmentFile
类,它也是一样的。
