需要实现#cache！如果要使用Cloudinary :: CarrierWave :: Storage作为缓存存储 [英] Need to implement #cache! if you want to use Cloudinary::CarrierWave::Storage as a cache storage

问题描述

尝试上传图片如果要使用Cloudinary :: CarrierWave :: Storage作为缓存存储区，则需要实现#cache！时出现此错误。
它突出显示了控制器中的这部分代码：

I am getting this error when trying to upload a picture "Need to implement #cache! if you want to use Cloudinary::CarrierWave::Storage as a cache storage." It highlights this part of code in my controller:

def update
  @company.update(company_params)
  redirect_to company_path(@company)
end

我正在使用Carrierwave将照片上传到cloudinary。
我的配置文件中有一个cloudinary.yml文件，而初始化程序中有一个cloudinary.rb。

I am using Carrierwave to upload photo to cloudinary. I have a cloudinary.yml file with my configuration as well as a cloudinary.rb in my initializers.

identitylogo_uploader.rb

identitylogo_uploader.rb

class IdentitylogoUploader < CarrierWave::Uploader::Base
  include Cloudinary::CarrierWave


  process :convert => 'png'
  process :tags => ['logo_entreprise']

  version :standard do
    process :resize_to_fill => [150, 150, :north]
  end

  version :thumbnail do
    resize_to_fit(50, 50)
  end


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

我注意到链接已生成，但文件未上传到cloudinary。

I noticed that the link is generated yet the file is not uploaded to cloudinary.

推荐答案

已将 config.cache_storage =：file 添加到载波初始化程序，并且错误消失了。 / p>

Added config.cache_storage = :file to carrierwave initializer and the error is gone.

CarrierWave.configure do |config|
 config.cache_storage = :file
end

这是更改的提交旧行为：链接

Here is the commit that change the old behavior : link
