This gem is based on mongoid-paperclip 0.0.4. It is a fork of Leo Lou's original gem, updated for Neo4j.rb 3.0. It is platform-independent and compatible with Paperclip 4.2.0.
As the title suggests: Neo4jrb::Paperclip makes it easy to hook up Paperclip with Neo4j.rb.
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 4 and Bundler.
Simply define the neo4jrb-paperclip gem inside your Gemfile, pulling from subvertallchris/neo4jrb-paperclip. Additionally, you can define the aws-sdk 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 neo4jrb-paperclip.
Rails.root/Gemfile - Just define the following:
gem "neo4jrb-paperclip", github: 'subvertallchris/neo4jrb-paperclip', require: "neo4jrb_paperclip"
gem "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
include Neo4j::ActiveNode
include Neo4jrb::Paperclip
has_neo4jrb_attached_file :avatar
validates_attachment_content_type :avatar, content_type: ["image/jpg", "image/jpeg", "image/png", "image/gif"]
end
More or less. See Paperclip's documentation for additional instructions.
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
