CarrierWave::Uploader::Store#filename

Override this in your Uploader to change the filename.

Be careful using record ids as filenames. If the filename is stored in the database
the record id will be nil when the filename is set. Don't use record ids unless you
understand this limitation.

Do not use the version_name in the filename, as it will prevent versions from being
loaded correctly.

=== Returns

[String] a filename
