需要执行#cache！如果你想使用 Cloudinary::CarrierWave::Storage 作为缓存存储

Question

我在尝试上传图片时遇到此错误 "Need to implement #cache! if you want to use Cloudinary::CarrierWave::Storage as a cache storage." 它在我的控制器中突出显示了这部分代码：

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。我有一个包含我的配置的 cloudinary.yml 文件以及我的初始化程序中的一个 cloudinary.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
end

company.rb

class Company < ApplicationRecord
  mount_uploader :identitylogo, IdentitylogoUploader
end

companies_controller.erb

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

def company_params
  params.require(:company).permit(:identitylogo, :name, :industry, 
  :employees, :website)
end

_form.erb

<%= simple_form_for @company do |f| %>
  <%= f.input :name %>
  <%= f.input :industry %>
  <%= f.input :employees %>
  <%= f.input :website %>
  <%= f.input :identitylogo_cache, as: :hidden %>
  <%= f.input :identitylogo, label: false %>

  <%= f.button :submit %>
<% end %>

_show.html.erb

<img src="<%= @company.identitylogo %> " alt="Logo de 
l'entreprise">

我注意到 link 已生成，但文件尚未上传到 cloudinary。

Answer 1

最新版本的 CarrierWave 似乎与 Cloudinary 不兼容。

检查你的 Gemfile 和 Gemfile.lock。我必须删除 .rc-ending 并重新启动服务器。

Answer 2

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

CarrierWave.configure do |config|
 # For an application which utilizes multiple servers but does not need caches persisted across requests,
 # uncomment the line :file instead of the default :storage.  Otherwise, it will use the default storage as the temp cache store.
 config.cache_storage = :file
end

这是更改旧行为的提交：link
