Access Paperclip attachments from a rake task

Question

I have a Model in my app which has an attached file for xml files using Thoughtbot's Paperclip.

In my rake task I want to loop through the records, process the XML and marking them as processed. Simple enough. Except I don't know the URL to the attached files

pp xml_record.datafile

just gives the system path like this:

/system/thingstoprocess/datafiles/000/000/001/original/data.xml

and

File.open(xml_record.datafile.url)

gives a no such file or directory error.

How can I pass the file to my Nokogiri class for processing?

Answer 1

Worked it out (by which i mean found on google somewhere)

xml_record.datafile.path

Gives the correct path to read for Nokiogiri. It even works with S3 storage when deployed on heroku (which seems magical)
