ruby-on-rails-3 - 将图像存储在本地以供开发s3用于生产Rails回形针

Question

我想将图像上传到本地计算机上进行开发，但将其存储在我的Amazon S3帐户中进行生产。

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

这里有一些代码重复。
有没有一种方法可以编写此代码而无需代码重复。

这是解决方案感谢您在下面感谢乔丹和安德烈:

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 ]
  }

Answer 1

当然。尝试这样的事情:

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

unless Rails.env.development?
  paperclip_opts.merge! :storage        => :s3,
                        :s3_credentials => "#{RAILS_ROOT}/config/s3.yml",
                        :path           => ':attachment/:id/:style.:extension',
                        :bucket         => 'birthdaywall_uploads',
end

has_attached_file :photo, paperclip_opts

除了明显的 unless / merge!块外，还请注意将 :all用于 :convert_options，而不是指定相同的选项三次。
