Question

所以我正在使用fb_graph gem从facebook中提取数据，以便在我的应用程序中创建新事件。麻烦的是，我似乎无法使用remote_image_url通过carrierwave上传图片。这是organization.rb的代码：

  page = FbGraph::Page.fetch(uri, :access_token => token)
  org_events = page.events({:fields => "name,description,picture,id,location,start_time"})
  org_events.each do |event|
    Event.create!(
        :name => event.name,
        :description => event.description,
        :location => event.location,
        :date =>event.start_time ,
        :time => event.start_time,
        :organization_id => self.id,
        :remote_image_url => event.picture  #broken code
    )
  end

这是从模型顶部安装的上传器和图像属性：

attr_accessible :image
mount_uploader :image, ImageUploader

这是我遇到的错误消息 -

Can't mass-assign protected attributes: remote_image_url

试试这个，

  org_events.each do |event|
   myEvent = Event.new(
    :name => event.name,
    :description => event.description,
    :location => event.location,
    :date =>event.start_time ,
    :time => event.start_time,
    :organization_id => self.id
  )
  myEvent.remote_image_url = event.picture
  myEvent.save!
  myEvent
 end

我们正在使用myEvent.remote_image_url，因为remote_image_url是一个辅助方法

无法分配remote_image_url carrierwave
