Question

通过cloudinary上载图像可在localhost上进行，但在rails app部署在heroku上时则无法。（即“很抱歉，但是出了点问题”）

代码：upload_file = params [：log] [：picture] .path cloudinary_file = Cloudinary :: Uploader.upload（uploaded_file，：folder =>“铁路新闻”）。

我已经指出，在本地打印出uploaded_file会显示“ / var / folders / 2f / ...”，但是在heroku中会显示“ /tmp/RackMultipart20190606-4-1i7nfxh.jpg”。

在logs_controller.rb文件中：

def update
    @log = Log.find(params[:id])

    if params[:log][:picture]
      p "begin cloudinary upload if there is image: "
      uploaded_file = params[:log][:picture].path
      p "printing uploaded_file path below: "
      p uploaded_file
      cloudinary_file = Cloudinary::Uploader.upload(uploaded_file, :folder => "journal-on-rails")

      p "printing cloudinary_file below: "
      p cloudinary_file

      p "printing cloudinary_file url below: "
      p cloudinary_file["url"]


      @log.attributes = {:image => cloudinary_file["public_id"]}
    else
      log_params[:image] = @log.image
    end

    respond_to do |format|
      if @log.update(log_params)
        format.html { redirect_to @log, notice: "Entry updated!" }
        p "Log updated!"
      else
        format.html { render action: 'logs/edit' }
      end
    end
  end

在edit.html.erb文件中：

<<%= form_with scope: :log, model: @log, local: true do |form| %>
  <p>
    <%= form.label :title, 'Entry Title' %><br>
    <%= form.text_field :title, class: "title-text-field" %><br>
        <%= form.label :content, "Content - Great! Felt better?" %><br>
        <%= form.text_area :content, class: "log-text-area"%><br>
        <%= form.label :picture %><br>
        <%= cl_image_tag(@log.image, :width => 350, :fetch_format=>:auto, :crop=>"scale") %><br>
    <%= form.file_field :picture %><br>
  </p>
  <p>
    <%= form.submit %>
  </p>
<% end %>

<%= link_to 'Back', log_path, class: 'btn btn-primary' %>

我的heroku Journal on Rails网络应用程序：https://agenda-journal-on-rails.herokuapp.com/

在localhost中，我可以创建标题，正文，还可以通过Cloudinary上传图像。根路径显示日记条目/日志的列表，以及上载图像的缩略图。但是在heroku中，当在生产环境中部署时，所有的cloudinary函数都无法正常工作。结果，没有缩略图。

我得出的结论是，Cloudinary的cl_image_tag（）帮助器方法正在运行。因为我可以获取它以获取我的cloudinary帐户中的另一个public_id。但是在Heroku中，当执行POST方法进行编辑时。我在“ heroku日志--tail”中收到此错误：

2019-06-06T05：18：07.303488 + 00：00 heroku [router]：at = info method = POST path =“ / logs / 3” host = agenda-journal-on-rails.herokuapp.com request_id = f7c5bdff-79e2-4f28-b500-f5ffecdc4246 fwd =“ 129.126.207.229” dyno = web.1 connect = 0ms service = 819ms status = 500 bytes = 1827 protocol = https

cloudinary：“ uploaded_file = params [：person] [：picture] .path”在本地运行，但在heroku部署上不运行
