Build Status: CircleCI

Code Quality: Codacy Badge

Documentation

If you are new to SlicingDice, check our quickstart guide and learn to use it in 15 minutes.

Please refer to the SlicingDice official documentation for more information on how to create a database, how to insert data, how to make queries, how to create columns, SlicingDice restrictions and API details.

Tests and Examples

Whether you want to test the client installation or simply check more examples on how the client works, take a look at tests and examples directory.

Installing

In order to install the Ruby client, you only need to use gem.

$ curl -s https://packagecloud.io/install/repositories/slicingdice/clients/script.gem.sh | bash
$ gem install rbslicer

Usage

The following code snippet is an example of how to add and query data using the SlicingDice ruby client. We entry data informing 'user50@slicingdice.com' has age 22 and then query the database for all users between 20 and 40 years old. If this is the first record ever entered into the system, the answer should be a list whose only element is 'user50@slicingdice.com'.

require 'rbslicer'

# Configure the client
client = SlicingDice.new(master_key: "API_KEY")

# Inserting data
insert_data = {
    "user50@slicingdice.com" => {
        "age" => 22
    },
    "auto-create" => ["dimension", "column"]
}
client.insert(insert_data)

# Querying data
query_data = {
    "query-name" => "users-between-20-and-40",
    "query" => [
        {
            "age" => {
                "range" => [
                    20,
                    40
                ]
            }
        }
    ]
}
puts client.count_entity(query_data)

Reference

SlicingDice encapsulates logic for sending requests to the API. Its methods are thin layers around the API endpoints, so their parameters and return values are JSON-like Hash objects with the same syntax as the API endpoints

Attributes

  • keys (String) - API key to authenticate requests with the SlicingDice API.

Constructor

initialize(master_key: nil, custom_key: nil, read_key: nil, write_key: nil, timeout: 60, use_ssl: true)

  • master_key (String) - API key to authenticate requests with the SlicingDice API.
  • custom_key (String) - API key to authenticate requests with the SlicingDice API.
  • read_key (String) - API key to authenticate requests with the SlicingDice API.
  • write_key (String) - API key to authenticate requests with the SlicingDice API.
  • use_ssl (Bool) - Define if the requests verify SSL for HTTPS requests.
  • timeout (Fixnum) - Amount of time, in seconds, to wait for results for each request.
