How to install?

Add this to your Gemfile

gem 'prediction_io'

Install with Bundler

bundle install

Install with gem install

gem install prediction_io

---

Configurations have to be pre-defined in config/prediction_io.yml Such as:

user:
  username: batman
  password: secret

api:
  appkey: my_supersecret_key
  host: http://localhost:3000
  timeout: 5
  proxy: null
  pool: 5

Bear in mind:

PredictionIO::Worker is responsible for 'getting the job done' whenenver you make a request. ( e.g aget(1), acreate(1) ) It is also smart enough to call a fallback when an exception is encoutered, therefore, Whenever a exception is raised it will call a fallback which will return an instance of OpenStruct object with two methods defined:

• notice -> What the exception raised has returned.
• worker -> The worker assigned to that particular job.

The catch here is, if you call a method that an instance of OpenStruct does not respond to it will return nil, this prevents other exceptions from being raised. For example:

  PredictionIO::User.adelete(4){ |response|
    puts response.id
  }
  # => nil

  PredictionIO::User.adelete(4) { |r|
    puts r.notice.response.code
  }
  # => 404

Usage:

###Creating an user

  Prediction::User.acreate(1, { pio_latlgn: [ 23.0, 20.1 ] })

  # Or if you need to do something with the response:
  Prediction::User.acreate(1, { pio_latlgn: [ 23.0, 20.1 ] }) { |u|
  # this will be called whenever this job is done.
    puts u.id
  }
  # => 1

###Getting an user

  Prediction::User.aget(1)

  # OR

  Prediction::User.aget(1, { extra_params }) { |u| print u.id }

###Deleting an user

  PredictionIO::User.adelete(1)
  # OR
  PredictionIO::User.adelete(1) { |u| ... }
