ruby-on-rails - tinymce 图片上传后服务器响应错误

Question

我正在尝试使用回形针和 tinymce-rails-image-upload 上传图像关注this演示。我正在问题模型中上传图像(属于评论)。当我上传时，我收到“从服务器收到错误响应”消息，并且图像未显示在编辑器中，但它确实创建了一个新问题。

这是我上传后的日志:

Processing by TinymceAssetsController#create as HTML

Completed 200 OK in 68ms (Views: 0.6ms | ActiveRecord: 8.7ms)

这是tinymce Controller :

class TinymceAssetsController < ApplicationController
respond_to :json

def create
  geometry = Paperclip::Geometry.from_file params[:file]
  question = Question.create params.permit(:file, :alt, :hint)

 render json: {
   question: {
   url:    question.file.url,
   height: geometry.height.to_i,
   width:  geometry.width.to_i
  }
 }, layout: false, content_type: "text/html"

 end
end

问题 Controller 创建操作如下所示(我是否向tinymce Controller 添加@comment和附加参数？):

def create
  @comment = Comment.find(params[:comment_id])
  @question = @comment.questions.new(question_params)
end
...
def question_params
  params.require(:question).permit(:body, :comment_id, :user_id, :file, :position)
end

问题模型:

class Question < ActiveRecord::Base
  has_attached_file :file
end

和编辑器 View :

<%= simple_form_for [@comment, Question.new] do |f| %>    
<%= f.text_area :body, :class => "tinymce", :rows => 10, :cols => 60 %>
<% end %>
<%= tinymce plugins: ["uploadimage"] %>

我很困惑为什么它为每个上传的图像创建一个新问题以及仍然导致“错误响应”错误的原因。

似乎tinymce-rails-imageupload需要“图像”来响应上传的文件

render json: {
   image: {
   url:    question.file.url,
   height: geometry.height.to_i,
   width:  geometry.width.to_i
  }
 }, layout: false, content_type: "text/html"
