Form ajax upload to s3

Francisco Quinones asked in Rails

Hi!, So I have a form that was using ajax to post the data to the server, then I add it a img file and the process was taking to long so now I want to do direct upload to s3.

https://gist.github.com/Frank004/2424f5ddcf742846e9c26a3b82e83277

I setup the :

  • aws
  • cors
  • form
  • ajax
  • presigned_post

Im getting this error Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin'. I think that my persigned data its not passing correct on the ajax.
