argumenterror (missing required :bucket option):

that's error, , it's defined paperclip problem.

the issue you're trying use s3 connectivity in paperclip, have not defined bucket option (which required)

---

fix

there 2 ways fix problem:

1) model

as defined in paperclip docs, can set bucket option in model:

#app/models/your_model.rb has_attached_file :image,         :styles => { :medium => "x300", :thumb => "x100" },         :storage => :s3,         :bucket => '******',         :s3_credentials => s3_credentials 

2) config

a far more robust way use config files of system fix it. way use production.rb file define bucket once:

#config/environments/production.rb .... paperclip::attachment.default_options.merge!({     storage: :s3,     s3_credentials: {       access_key_id: env['aws_access_key_id'],       secret_access_key: env['aws_secret_access_key']     },     bucket: env['s3_bucket_name'] }) 

---

as may able tell; both of these our current codebase, should work. issue may have config script might need tweaking. if comment, i'll help
