Time to add some images to a Ruby project that I am working on. I have a Projects model already that has some basic content. I want to enable people to upload images and associate them with a specific project. Later on, I hope to add in permissions so only Admins can access add/change/delete, and automate thumbnails so that on the /index page, relevant pictures show up automatically.
There are three popular plugins available for Ruby on Rails: Paperclip, CarrierWave and Dragonfly.
Everyone needs ImageMagick to run. It processes images, reading and writing from all the varied image file formats in the wild.
Get ImageMagick loaded.
brew install imagemagick and you should have Homebrew.
If you also want to install GhostScript for fun PDF uploads.
brew install gs.
gem "paperclip" to your Gemfile.
And of course, stop your Rails server,
bundle and restart. Proceed if your site is not destroyed.
Paperclip (RIP Clippy)
We all miss you Clippy.
We need to add a model for our images. I’m going to use Rails scaffolding because that’s what refactoring is for
rails g scaffold paperclip_image --skip-assets. (Run first with the -p flag for “pretend” on the end to see what it would do).
