This is a small engine that allows you to manage slideshows.
Add gem definition to your Gemfile:
gem 'comfy_carousel'
Then from the Rails project's root run:
bundle install
rails g comfy:carousel
rake db:migrate
You should be able to access /admin/carousel/carousels where you can add carousels and their slides.
This gem comes bundled with slides.jquery.js that you can use via asset pipeline by adding this line to your app/assets/javascripts/application.js:
//= require slides.jquery
You'll notice that carousels have dimensions field. You can force-resize uploaded images via ImageMagic values. For example: 300x200# will resize any image to be 300px wide and 200px in height. Also it will crop image if necessary.
There's nothing on the front-end really. You have access to Carousel::Carousel objects that in turn can be used to access their slides. Like so:
@carousel = Carousel::Carousel.find_by_identifier('my_carousel')
@slides = carousel.slides
Each slide will have following attributes: label, content, url, file (paperclip object), and position
