This is a great use case for a background job. Have you tried Resque? If I have a user uploading thousands of rows, all of which need to be validated and processed/saved, I’d do it like this: Let the user upload the file, save it somewhere. Trigger a Resque job. Read the file one or more rows at a time, make a ActiveRecord or ActiveModel object out of them and run the validators. Collate the errors and include the row number. If all the rows were valid, continue processing or saving. If not, send an email to the uploader and/or show in his dashboard the failure message, along with a list of all errors with row numbers.
I’ve used this method in our app, and is working out great for our users. -- Dheeraj Kumar On Tuesday, 5 November 2013 at 10:45 am, Fahim Patel wrote: > @tam - I am even not sure how can experiment it.
