store images locally for development s3 for production Rails Paperclip

Question

I want to upload images on my local machine for development but store them on my Amazon S3 account for production.

upload.rb

if Rails.env.development?
  has_attached_file :photo, :styles => { :thumb => '40x40#', :medium => '150x200>', :large => '300x300>'},
                            :convert_options => { :thumb => "-quality 92", :medium => "-quality 92", :large => "-quality 92"  },
                            :processors => [:cropper]
else
  has_attached_file :photo, :styles => { :thumb => '40x40#', :medium => '150x200>', :large => '300x300>'},
                            :convert_options => { :thumb => "-quality 92", :medium => "-quality 92", :large => "-quality 92"  },
                            :storage => :s3,
                            :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
                            :path => ":attachment/:id/:style.:extension",
                            :bucket => 'birthdaywall_uploads',
                            :processors => [:cropper]
end

There is some code repetition here. Is there a way to write this without code duplication.

Here is the solution Thanks big time to Jordan and Andrey below:

config/environments/development.rb

   PAPERCLIP_STORAGE_OPTS = {
     :styles => { :thumb => '40x40#', :medium => '150x200>', :large => '300x300>' },
     :convert_options => { :all => '-quality 92' },
     :processor       => [ :cropper ]
   }

config/environment/production.rb

  PAPERCLIP_STORAGE_OPTS = {
    :styles => { :thumb => '40x40#', :medium => '150x200>', :large => '300x300>' },
    :convert_options => { :all => '-quality 92' },
    :storage        => :s3,
    :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
    :path           => ':attachment/:id/:style.:extension',
    :bucket         => 'birthdaywall_uploads',
    :processor       => [ :cropper ]
  }

One more solution is to move the hash with params to constants, which will be defined in config/environments/*.rb files. Then you can just use

has_attached_file :proto, PAPERCLIP_STORAGE_OPTS

Using if/unless in model while defining methods is a bit messy I think
