I am using paperclip for some image uploading in my ruby on rails application. Everything works fine locally.

When I deploy to heroku, the upload appears to work but when I look at my item it is obvious the upload has somehow failed - see Companylogo field:

Please see the form and try it yourself:

This is my gemfile:

I believe I have Paperclip in file storage mode. Perhaps this is not allowed on heroku....if this is the case - how do I get Paperclip to store files in my pg database instead?

As i believe you cannot write directly to Heroku which is what i believe to be your problem. Therefore you have to use a file storage system-I have always used Amazon s3 for image storing. This will take a few amendments but it is fairly easily set up! Your first step will be to get an Amazon s3 account which is free-at least for the first year. You will need to add these to the gemfile 

gem 'aws-sdk'

Following this you need to create a bucket on the Amazon s3 website which is what will act as an object container. Then you will need to get an access key and secret access key which you need to keep somewhere safe! In the config/production you will need to set something along the lines of this..

  config.paperclip_defaults = {
            :storage => :s3,
            :s3_credentials => {
              :bucket => ENV['AWS_BUCKET'],
              :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
              :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
            },
            :path => ":class/:id/:basename_:style.:extension",
            :url => ":s3_sg_url"
      }

Then in the config initializer a file called paperclip.rb needs to be made and something along the lines of the following should be input!

Paperclip.interpolates(:s3_sg_url) do |att, style| 
"#{att.s3_protocol}://s3-ap-southeast-1.amazonaws.com/#{att.bucket_name}/#{att.path(style)}"
end

For more information and instructions i suggest reading this https://devcenter.heroku.com/articles/paperclip-s3

  • Do you think it would be possible to implement an option where in development I could store files in the default way , on local disk, and when deployed to production it uses S3. This would mean I could continue my development offline without always needing a web connection to hit S3 whenever I am developing - which is not always accessible. – RenegadeAndy Jan 26 '15 at 15:55
  • Yes i think you would just specify this is code in your config/environments production and development files. I think the code would be something like below... – Lilp Jan 26 '15 at 18:06
