This ruby on rails gem makes it easy to store polymorphic structure information ---
descendants, ... --- in a neo4j graph database parallel to using ActiveRecord.
All relevant information is stored in your default ActiveRecord database, including the parent-child relationships. But, in addition, the structure information is also stored in a neo4j graph database in order to use its power of fast graph traversing queries.
TODO: Write usage instructions here
Add the gem to your application's
# Gemfile # ... gem 'neo4j_ancestry'
And then execute:
# bash bundle install
Install the neo4j database
db directory and start the deamon:
# bash bundle exec rake neo4j:install neo4j:setup neo4j:start
Next, migrate the database in order to add the neccessary tables.
# bash bundle exec rake neo4j_ancestry:install:migrations bundle exec rake db:migrate
- The neo4j graph database
- The neography gem is used as datbase interface.
- The neoid gem is used for database abstraction in parallel to ActiveRecord.
- Fork it
- Create your feature branch (
git checkout -b my-new-feature)
- Commit your changes (
git commit -am 'Add some feature')
- Push to the branch (
git push origin my-new-feature)
- Create new Pull Request
Running the Gem's Specs Locally
Gemfile according to the Rails version you would like to use:
# bash rm Gemfile Gemfile.lock ln -s rails3.2.Gemfile Gemfile # for Rails 3 ln -s rails4.Gemfile Gemfile # for Rails 4 (default)
Next, install the dependencies and run the specs.
# bash bundle install bundle exec rake neo4j_ancestry:db:test:prepare bundle exec rake
