Ruby On Rails Interview Questions and Answers

Ques. HOW CAN YOU UPLOAD A FILE TO A SERVER in Ruby on Rails?
Ans.

Paperclip is the best solution to manage file uploads to a server.

It can also help you with multiple file uploads and associate it with ActiveRecord.

There are also good examples online that show how you can make rotating sliders with the paperclip images.

Another nice solution is using carrier_wave gem. 

The nice thing about carrier_wave is that it has good documentation on how to integrate with S3, Google & Rackspace for file storage.

You can achieve the same file storage capability with Paperclip as well though. 

Is it helpful? Yes No
