I am trying to upload images to S3 using paperclip. It currently works perfectly in development, but when I push it to heroku I get a status 500.
I've looked on current topics and some reasons for this are either the lack of a pg gem and bucket name not configured but I've checked those.
My error log currently says this

The only hint I have is that status=500.
Would really appreciate any thoughts / help!

Answer 1

ENV Vars
The most pertinent issue will likely be that you've not got your ENV variables set up correctly. These are environment specific - meaning you will have to set them in each "environment" (server) you deploy your app to
A common problem for many is they will deploy to Heroku without setting these ENV vars, consequently preventing the system from accessing the information it needs.
The solution is to use heroku config:set VARIABLE=value in your CMD
--
Production
Your log doesn't have any errors, which isn't very helpful
One other piece of speculation, therefore, would be the idea that you've not set the production environment options in Rails itself:
#config/environments/production.rb
config.paperclip_defaults = {
:storage => :s3,
:s3_credentials => {
:bucket => ENV['S3_BUCKET_NAME'],
:access_key_id => ENV['AWS_ACCESS_KEY_ID'],
:secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
}
}
There is another issue you may have, which is how paperclip uses the bucket option. We've found that it requires this setup to work correctly:
#config/environments/production.rb
config.paperclip.defaults = {
storage: :s3,
s3_host_name: 's3-eu-west-1.amazonaws.com',
s3_credentials: {
access_key_id: ENV['AWS_ACCESS_KEY_ID'],
secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']
},
bucket: ENV['S3_BUCKET_NAME']
}
