CouchDB
=====
Dragonfly can be used with any ActiveModel-compatible model, and so you can use it with CouchDB using [CouchRest::Model](https://github.com/couchrest/couchrest_model).
Since CouchDB allows you to store files directly on documents as attachments, you can also use the supplied {Dragonfly::DataStorage::CouchDataStore CouchDataStore}.
which allows storing files as attachments directly on documents.
For more info about ActiveModel, see {file:Models}.
For more info about using the Couch data store, see {file:DataStorage}.
Example setup in Rails, using CouchRest::Model
-------------------------------------
In config/initializers/dragonfly.rb:
require 'dragonfly'
app = Dragonfly[:images]
# Get database config from config/couchdb.yml
couch_settings = YAML.load_file(Rails.root.join('config/couchdb.yml'))[Rails.env]
# Configure to use ImageMagick, Rails defaults, and the Couch data store
app.configure_with(:imagemagick)
app.configure_with(:rails) do |c|
c.datastore = Dragonfly::DataStorage::CouchDataStore.new(
:host => couch_settings['host'],
:port => couch_settings['port'],
:username => couch_settings['username'],
:password => couch_settings['password'],
:database => couch_settings['database']
)
end
# Allow all CouchRest::Model models to use the macro 'image_accessor'
app.define_macro(CouchRest::Model::Base, :image_accessor)
# ... any other setup, see Rails docs
Then in models:
class Album < CouchRest::Model::Base
property :cover_image_uid
image_accessor :cover_image
# ...
end
See {file:Models} for more info.
