This quick post is about some Paperclip-related code that I see quite frequently that could cause problems. It’s easy to miss this stuff in development and then get major headaches later.

Adding multiple images to a Rails model with paperclip

How to add multiple images to a rails model – all in one form!

The Goal

I have been working on improving the admin section of a ski club website. The club sells ski trips online and they need to be able to create new trips from the admin panel. A trip has a title, description, date and price. For marketing reasons when the trip information is displayed on the website a number of pictures related to the trip are also displayed in a slideshow. The goal was to allow admins to add a new trip to the website (including the images) through a single form. Up until now, admins had to create the trip text data and then add the images separately through another form.

The Solution

The solution makes use of Paperclip (the awesome file attachment ruby gem) and the nested attribute functionality that has been added in rails 2.3. If you are new to these I strongly suggest watching these two screencasts from Railscasts: http://railscasts.com/episodes/196-nested-model-form-part-1 and http://railscasts.com/episodes/134-paperclip

To install paperclip add the following line to the environment.rb file and run rake:gems:install

config.gem "thoughtbot-paperclip", :lib => "paperclip"
