CarrierWave for Neo4j

This gem adds support for Neo4j 3.0+ (neo4j.rb 9.6.0+) to CarrierWave 2.1.0+, see the CarrierWave documentation for more detailed usage instructions.

Installation Instructions

Add to your Gemfile:

gem 'carrierwave-neo4j', '~> 3.0', require: 'carrierwave/neo4j'

You can see example usage in spec/neo4j_realistic_spec.rb but in brief, you can use it like this:

class AttachmentUploader < CarrierWave::Uploader::Base
  storage :file

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end
end

class Asset
  include Neo4j::ActiveNode

  property :attachment, type: String
  mount_uploader :attachment, AttachmentUploader
end

If you want image manipulation, you will need to install ImageMagick

On Ubuntu:

sudo apt-get install imagemagick --fix-missing

On macOS:

brew install imagemagick

Development

bundle install
rake neo4j:install[community-latest,test]
rake neo4j:start[test]
rake spec

Troubleshooting

Files are nil

If you aren't getting your files back after querying a record from Neo4j, be aware that this will only happen automatically for the Model#find method. For all other finders (#all, #first, #find_by, #find_by_*, #find_by_*!, #last) you will need to force a reload so the model sees the file. For example:

users = User.all
users.each(&:reload_from_database!)

Sorry, this sucks. But this is a limitation of Neo4j.rb as these other finders don't fire any callbacks.

binstubs (particularly bin/rspec) seem broken

If you're getting some infinite recursion when you run the specs that ultimately results in an error like:

`ensure in require': CRITICAL: RUBYGEMS_ACTIVATION_MONITOR.owned?: before false -> after true (RuntimeError)

You may want to try:

rm .bundle/config
bundle install
