Exchange paperclip with dragonfly for image processing in Spree.
This extension is not maintained anymore
Add the spree_dragonfly gem to your bundler Gemfile:
gem 'spree_dragonfly'
From your spree rails root path:
rails generate spree_dragonfly:install
Customize the dragonfly initializer in config/initializers/dragonfly.rb if necessary.
Include this code in your application.rb:
config.middleware.insert 0, 'Rack::Cache', {
:verbose => true,
:metastore => URI.encode("file:#{Rails.root}/tmp/dragonfly/cache/meta"),
:entitystore => URI.encode("file:#{Rails.root}/tmp/dragonfly/cache/body")
}
config.middleware.insert_after 'Rack::Cache', 'Dragonfly::Middleware', :images
If you want to keep using the default image sizes as defined in the Spree config, you can use:
image.attachment.mini.url
image.attachment.small.url
image.attachment.product.url
image.attachment.large.url
If you want to use custom thumbnail sizes in your views as custom in dragonfly, you can use any valid dragonfly image processing method. For example:
image.attachment.process(:greyscale).process(:thumb, '40x20#').encode(:gif).url
To apply your own thumbnail sizes to existing views in spree, use deface overrides or override the whole template view file or partial. Example deface override:
Deface::Override.new(:virtual_path => "spree/products/_image",
:name => "products_image",
:replace => "code[erb-loud]:contains('image_tag image.attachment.product.url, :itemprop => \"description\"')",
:text => "<%= image_tag image.attachment.process(:thumb, '400x400>').url, :itemprop => \"description\"') %>")
To implement image attachment validations, create a image_decorator.rb file in app/models of your spree rails app:
Spree::Image.class_eval do
validates_size_of :attachment, maximum: 500.kilobytes
