Heroku - Ruby on Rails - Upload of pictures

Question

we are working on the PYL project ( a kind of social network dealing with pictures users can modify ). we have the code for some function of the website which work on the localhost ( upload, modify...) but when we want to put in in the internet through Heroku the code doesn't work for the upload !

(I use paperclip)

In fact, the webside ask the user to upload the file, he can chose the picture hi wants but when he submits, the picture doesn't appear and we have an error !

The error : "We're sorry, but something went wrong." Here my heroku logs :

What is the problem ? The database ? Do I have to create a Amazon S3 account to be abble to upload and save images from my website ? It should work even without a Amazon S3 account isn't it ?

Thank you

Answer 1

To respond to my own question, in fact you can upload a picture on Heroku but it will be a temporary file and will be send to trash.(I did'nt make it works with paperclip but I know that for example with carrierwave it works).

I solved my problem making work the upload thing with amazon AWS S3 ( to store permanently my files).

Answer 2

As @TheChamp said, heroku's filesystem is ephemeral, but you should also beware that your logs display the following:

ActionController::RoutingError (uninitialized constant PhotoController):

Might want to investigate that if you find this issue still exists after switching to S3.

Answer 3

Heroku doesn't provide you with webspace for uploads, your assumption was right, setting it up with Amazon S3 is the way to go:
