Rails 4 - NoMethodError

Question

I am using the PaperClip, AWS, and s3_direct_upload gems to upload simple images. I am following this tutorial here: http://blog.littleblimp.com/post/53942611764/direct-uploads-to-s3-with-rails-paperclip-and

The file is uploaded successfully to S3, but during post-processing, I get the following error:

  Completed 500 Internal Server Error in 973ms

  NoMethodError (undefined method `upload_file_name=' for #<Choice:0x007f9ea60e02d0>):
   app/models/choice.rb:60:in `set_upload_attributes'
   app/controllers/choices_controller.rb:24:in `create'

Here is what my model ("Choice") looks like, where upload_file_name should be defined: https://gist.github.com/dodinas/7237377

Any ideas on what I am doing wrong here? Thanks very much!

Answer 1

Did you run your migrations. You would get that error if the column doesnt exist on the table in the database.
