What I do is create a csv file from the database. I had some memory problems there, but using active record find_in_batches() seemed to solve that. The CSV file has 1.4 million rows. It gets created successfully. I then use rubyzip gem to create a zip file that just contains that CSV file. I just used examples I found from google searches on how to create the zip file which are shown earlier up in the thread. I looked at the class info on the web for rubyzip and didn't see an obvious way to stream data into the zip file. Tomorrow I can look at perhaps some other way to create a zip file using a different gem or some such .. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
