问题:

Paperclip doc about url options:

You can choose to have the bucket's name placed domain-style (bucket.s3.amazonaws.com) or path-style (s3.amazonaws.com/bucket).

How would look like the setup to actually have bucket's name placed domain-style? I can't force paperclip to generate urls like bucket.s3.amazonaws.com instead of s3.amazonaws.com/bucket.

回答1:

Just set it like this:

Paperclip::Attachment.default_options[:url] = ':s3_domain_url'

Or like this:

Paperclip::Attachment.default_options.merge!(
  :url => ':s3_domain_url'
)

回答2:

Add :url and :path to the Paperclip default options in your application.rb or environment.rb

config.paperclip_defaults = {
  storage: :s3,
  s3_credentials: {
    bucket: ENV['MY_S3_BUCKET_NAME'],
    access_key_id: ENV['AWS_ACCESS_KEY_ID'],
    secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']
  },
  url: ':s3_domain_url',                                     # ADD THIS
  path: '/:class/:attachment/:id_partition/:style/:filename' # ADD THIS
}
