如何在rails中使用gem "ckeditor“从桌面上传视频？

<%= f.cktext_area :content %>

def article_params
  params.require(:article).permit(:title, :content)
end

class Article < ApplicationRecord
  attr_accessor :video
end

<%= form.file_field :video %>

def create
  @article = Article.new(article_params)
  @article.video = params[:article][:video] if params[:article][:video].present?
  if @article.save
    # 保存成功的逻辑
  else
    # 保存失败的逻辑
  end
end

<%= f.cktext_area :content, uploadUrl: upload_video_path %>

post 'upload_video', to: 'articles#upload_video'

def upload_video
  uploaded_video = params[:upload]
  # 处理上传的视频文件，保存到服务器或云存储等操作
  render json: { url: uploaded_video.url } # 返回视频文件的URL给CKEditor
end
