将照片上传到网站上需要绝对路径

Question

我使用rails 3用云和载波将照片上传到服务器。

class NutsController < ApplicationController
  include UsersHelper
  include NutsHelper

  def index
    if current_user
      @user = User.find(session[:user_id])
      @nuts = Nut.all
    else
      redirect_to :root
    end
  end

  def new
    # current_user
  end

  def show
  end

  def create
    if params[:file].present?
      @upload = Cloudinary::Uploader.upload(params[:file])
      @picture = @upload["secure_url"]
    end

    @nut = Nut.new(url: [@picture])
    if @nut.save
      redirect_to user_path(current_user)
    end
  end
end

<

<%= cloudinary_js_config %>
<h1>Create a Nushell</h1>
<%= form_for :nut, url: nuts_path do |f| %>

  <%= cl_image_upload_tag(:image_id) %>

  <%= f.submit "Nut it Up!"%>
<% end %>

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

  storage :file

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

我的文件名为Yellow_Happy.jpg。当我打印出params:file时，它返回‘黄_幸福. out’。要上传到cloudinary，我需要我的文件的整个路径，即用户/学徒/桌面/黄_幸福. the。有人知道如何指定我文件的整个路径吗？

如果您查看您的Uploader代码，您已经指定了storage :file，它基本上告诉载波在您的应用程序中上传图像，而store_dir函数则告诉您在哪里上传图像。您甚至可以在app/public/uploads中检查它。有关更多详细信息，请查看carrierwave documentation

如果您查看cloudinary documentation，您只需要在上传器中包含Cloudinary：：载波(除非您使用缩略图或其他载波功能)。上传者应该是这样的：

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

  #storage :file  #You don't need it

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