How to rename a file already uploaded with carrierwave?

Question

Ruby on Rails

Hello
It is necessary to rename existing files uploaded with carrierwave.
In the loader I changed the filename method
to be:

def filename
    "photo.jpg" if original_filename
  end

became:

def filename
    "#{secure_token}.jpg" if original_filename
  end
  
  protected
  def secure_token
    var = :"@#{mounted_as}_secure_token"
    model.instance_variable_get(var) or model.instance_variable_set(var, SecureRandom.uuid)
  end

I'm trying to recreate file versions using the rake task.

RoutePointPhoto.all.each { |i| i.photo.recreate_versions! }

But this only creates new files with the desired name, and does not change anything in the database. Tell me how to be?

Answer 1

After you have changed the filename method , run through the rake task or from the console

RoutePointPhoto.all.each do |p|
  p.photo.recreate_versions!
  p.save!
end
