This gem is based on mongoid-paperclip 0.0.4.
This is actually easier and faster to set up than when using Paperclip and the ActiveRecord ORM. This example assumes you are using Ruby on Rails 3 and Bundler. However it doesn't require either.
Make sure you are using JRuby. Simply define the
neo4jrb-paperclip gem inside your
Gemfile. Additionally, you can define the
aws-s3 gem if you want to upload your files to Amazon S3. You do not need to explicitly define the
paperclip gem itself, since this is handled by
Rails.root/Gemfile - Just define the following:
gem "neo4jrb-paperclip", :require => "neo4jrb_paperclip" gem "aws-s3", :require => "aws/s3"
Next let's assume we have a User model and we want to allow our users to upload an avatar.
Rails.root/app/models/user.rb - include the Neo4jrb::Paperclip module and invoke the provided class method
class User < Neo4j::Rails::Model include Neo4jrb::Paperclip has_neo4jrb_attached_file :avatar end
That's all you have to do. Users can now upload avatars. Unlike ActiveRecord, Neo4j doesn't use migrations normally, so we don't need to define the Paperclip columns in a separate file. Invoking the
has_neo4jrb_attached_file method will automatically define the necessary
:avatar fields for you in the background.
File size returns 0 - paperclip issue
