CarrierWave: Create the same, unique filename for all versioned files

Question

Before I go into detail I\'ll get right to the point: has anyone figured out a way to get Carrierwave to save files with their names as a timestamp or any arbitrary string that

Answer 1

Check also the solution from carrierwave wiki available now https://github.com/carrierwaveuploader/carrierwave/wiki/How-to:-Use-a-timestamp-in-file-names

You can include a timestamp in filenames overriding the filename as you can read in Carrierwave docs:

 class PhotoUploader < CarrierWave::Uploader::Base
     def filename
       @name ||= "#{timestamp}-#{super}" if original_filename.present? and 
       super.present?
    end

   def timestamp
     var = :"@#{mounted_as}_timestamp"
     model.instance_variable_get(var) or model.instance_variable_set(var, Time.now.to_i)
   end
 end

Don't forget to memorize the result in an instance variable or you might get different timestamps written to the database and the file store.
