Paperclip console command for Rails 4

I want to upload paperclip files in console mode. In rails 3, I tried this Paperclip: How to store a picture in a Rails console? - Stack Overflow and it worked.

YourPaperclippedModelHere.new(:your_paperclip_field => File.new(path,
“r”))

However, in Rails4, when I try this, I get

ActiveRecord::UnknownAttributeError: unknown attribute: your_paperclip_field

I am using the master branch of paperclip.

My guess would be, because of strong_params in Rails 4. You need to add

private
  def paperclip_model_parameters
    params.require(:parperclip_model_name).permit(:your_paperclip_field)
  end
