How can I set paperclip's storage mechanism based on the current Rails environment?

Question

I have a rails application that has multiple models with paperclip attachments that are all uploaded to S3. This app also has a large test suite that is run quite often. Th

How about this:

1. Defaults are established in application.rb. The default storage of :filesystem is used, but the configuration for s3 is initialized
2. Production.rb enables :s3 storage and changes the default path

Application.rb

config.paperclip_defaults = 
{
  :hash_secret => "LongSecretString",
  :s3_protocol => "https",
  :s3_credentials => "#{Rails.root}/config/aws_config.yml",
  :styles => { 
    :original => "1024x1024>",
    :large => "600x600>", 
    :medium => "300x300>",
    :thumb => "100x100>" 
  }
}

Development.rb (uncomment this to try with s3 in development mode)

# config.paperclip_defaults.merge!({
#   :storage => :s3,
#   :bucket => "mydevelopmentbucket",
#   :path => ":hash.:extension"
# })

Production.rb:

config.paperclip_defaults.merge!({
  :storage => :s3,
  :bucket => "myproductionbucket",
  :path => ":hash.:extension"
})

In your model:

has_attached_file :avatar
