jquery - 载波；在生产服务器上保存图像并移动它们？

Question

编辑:我的文件仅按照缓存而非 store_dir 的规定存储

我花了几个小时试图让它工作，Carrierwave 在本地工作，但在我的生产中，它们只保存在 Cache_dir 中，并且表单没有将我重定向到我指定的路径。

是否需要将文件从已发布的 TMP 文件夹移动到它应该在的位置？或者 carrierwave 不应该自动执行此操作吗？

如果有人想提供帮助，请发布大量代码。

我的文件被保存@:

/releases/20150601122454/public/uploads/tmp/pics/1433164111-29887-8666/elg.jpg 

我正在尝试用以下方式移动它:

require 'fileutils'
   tmp = params[:instruction][:image].tempfile
   newfile = File.join("public/system/pics",params[:instruction][:image].original_filename)
  FileUtils.touch('newfile') 
  FileUtils.copy_file(tmp.path,newfile)

这只会崩溃说

No such file or directory - public/system/pics/elg.jpg

她是我的 Image_Uploader:

class ImageUploader < CarrierWave::Uploader::Base

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

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




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

  def cache_dir
    "uploads/tmp/pics"
  end

这是我更新模型的方式:

def update
    file = params[:instruction][:image]
   puts @instruction.text + " HERE IT IS " +file.path
   @instruction.image = file
   @instruction.save
   Rails.logger.info("@inst.image path: " + @instruction.image.path)

  require 'fileutils'
  # tmp = params[:instruction][:image].tempfile
  # newfile = File.join("public/system/pics",params[:instruction][:image].original_filename)
   #FileUtils.touch('newfile') 
   #FileUtils.copy_file(tmp.path,newfile)

    if @instruction.update(instruction_params)
      redirect_to instructions_path, notice: 'Instruktionerna sparades.'
    else
     render action: 'edit' , alert: 'Misslyckades att uppdatera instruktionerna'
    end

结束

 def instruction_params
    params.require(:instruction).permit(:text,:role_id)
end

我的表格:

<%= form_for @instruction, :html => {:multipart => true} do |f| %>
  <div class="row">
    <div class="col-xs-12 col-sm-12 col-md-8 col-lg-8">
    <br>
    <div> 
    <%= f.file_field :image%>

    <%= f.hidden_field :image_cache %>
    </div>
    <br>
      <div class="form-group">
        <%= f.text_area :text, rows: 15, class: "form-control" %>
      </div>
    </div>
  </div>

  <%= f.submit 'Spara', class: "btn btn-primary" %>
<% end %>

模型:

class Instruction < ActiveRecord::Base
  belongs_to :role
  mount_uploader :image, ImageUploader
end

拜托拜托，我真的需要帮助。

Answer 1

可能的方法 #1 - 添加一个 /#{Rails.root}/public

File.join("/#{Rails.root}/public/system/pics",params[:instruction][:image].original_filename)

可能的方法 #2

Verify that Rails has permission to read/write to your file system.

引用类似于我在生产atm中运行的代码

这与我们在生产中使用的代码相似，效果很好。

class SomeUploader < CarrierWave::Uploader::Base
  ...

  # 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
    if Rails.env.production?
      "uploads/prod/#{model.id}"
    else if Rails.env.staging?
      "uploads/staging/#{model.id}"
    else
      "uploads/dev/#{model.id}"
    end
  end
