Rack
====
For more info about using Rack applications, see the docs at {http://rack.rubyforge.org/}
Basic usage involves storing data (e.g. images),
then serving it in some form.
A basic rackup file `config.ru`:
require 'rubygems'
require 'dragonfly'
Dragonfly[:my_app_name].configure do |c|
# ... configuration here
end
run Dragonfly:App[:my_app_name]
See {file:Configuration} for more details.
The basic flow is instantiate an app -> configure it -> run it.
Example: Using to serve resized images
--------------------------------------
`config.ru`:
require 'rubygems'
require 'dragonfly'
app = Dragonfly[:images].configure_with(:imagemagick)
run app
This enables the app to use all the ImageMagick goodies provided by Dragonfly (see {file:Configuration}).
By default the {Dragonfly::DataStorage::FileDataStore file data store} is used.
In the console:
app = Dragonfly[:images]
# Store
uid = app.store(File.new('path/to/image.png')) # ===> unique uid
# Get the url for a thumbnail
url = app.fetch(uid).thumb('400x300').url # ===> "/media/BAhbBlsHOgZmIg9hc..."
Now when we visit the url `/media/BAhbBlsHOgZmIg9hc...` in the browser, we get a resized image!
