Uploading carrierwave files to a subdomain?

Question

Ruby on Rails

Hello!
I dug out config.asset_host in the settings, and there you can specify which domain will be added to the path to the file
. But I don’t understand how to upload files to a subdomain (adjacent folder with the project), and so that later I pull out a link through image_url, that subdomain is taken, and accordingly the path to the file?

Answer 1

This parameter is not intended for uploaded files, but for application assets - styles, js code, icons.
Carrerwave can be used with S3 to store files not on the machine where the application is running. Or what do you mean by uploading to a subdomain?
To upload to a different folder on the machine, you need to configure the carrierwave uploader

class FileUploader < CarrierWave::Uploader::Base

  def store_dir
    model_class = model.has_attribute?(:type) ? model.type : model.class.to_s
    "uploads/#{model_class.underscore}/#{mounted_as}/#{model.id}"
  end

end

store_dir can contain both a relative path (like here) and an absolute path
