The Antaeus SDK for Ruby

About

Antaeus is a guest management system written by KnuEdge. The name comes from a figure in Greek mythology that would challenge travellers passing through his land to compete with him in a wrestling match. While this application has little to do with wrestling, it is used to track passers-by at KnuEdge office locations.

This is the Ruby SDK designed to aid in and serve as a reference for interacting with the Antaeus API. This SDK is certainly not required to use the API (everything could be done with curl calls or most any REST client), but it provides first-class Ruby objects to make things easy for a Ruby developer. It also happens to serve as the basis for the Antaeus Web application.

Building and Installing

Building the gem requires a modern Ruby:

# highly recommend using RVM here, and Ruby 2.x or above
gem build antaeus-sdk.gemspec
# install what you just built
gem install antaeus-sdk-*.gem

That said, recent releases should be available on rubygems.org so building is probably not necessary.

Just add the following to your Gemfile:

gem 'antaeus-sdk', '~> 0.2'

Then run:

bundle install

If you're not using bundler for some reason (shame on you!), you can manually install like so:

gem install antaeus-sdk

If you see a message like this:

Thanks for installing the Antaeus Ruby SDK!

You should be all set!

Usage

Check back, because this file will be updated with a lot more usage examples.

For simplicity, this gem includes a CLI application for interacting with an API backend. To use it, run:

$ antaeus-cli

It should be in your PATH. On the first run, it will create a directory called ~/.antaeus (meaning it places it in your home directory), and it will drop a base configuration for the tool at ~/.antaeus/client.yml. Edit this file, specifically changing base_url, login, and password as required. This document will be updated to show all configuration options available, along with their default values, in the future.

The CLI tool really is just a shortcut to the next few lines of boilerplate code to connect to the backend API and reuse configuration from a config file.

For a typical custom ruby application, you'll need to do something like the following to get started:

require 'antaeus-sdk'

# create an 'instance' of the User API Client Singleton
client = Antaeus::UserAPIClient.instance
# authenticate
client.authenticate 'username', 'password'

From here, whether using the provided CLI tool or building a custom application, the instructions are the same.

First, connect the client to the API backend and obtain an API token:

client.connect

You'll probably see something similar to the following:

=> #<RestClient::Resource:0x007fa693ecbbe8
 @block=nil,
 @options=
  {:content_type=>:json,
   :accept=>:json,
   :headers=>{:"X-API-Token:"=>"cv0qTNvJsTRMEn2jzLBvb+T25l6zc8feG3s62Q6XDPbB9isxG3gJ1wxRpyxINHgPRd9lu+afLrIzFj50KjLIFtPkGc5bOJKyO7BCCWFGY0erhbhFpXLJZg=="}},

This API client is built to be very flexible, working for both guest users (using the GuestAPIClient), typical users (using the UserAPIClient shown in this example), as well as for trusted front-end applications (using the same UserAPIClient in multi-user / impersonation mode). For this reason, Antaeus resources (subclasses of the Antaeus::Resource class) need to know which client to use to perform a given operation on the backend API. These resources are smart enough to keep using the same client, but a client (a sublcass of the Antaeus::APIClient class) must be provided to all class methods. For instance:

# Retrieve a list of all Guests known to the system
guests = Antaeus::Resources::Guest.all(client: client)

Note though, that any objects created using a class method with a client provided carry along that same client. This means that method chaining (for instance, on resource collections) is simple:

# For simplicity, include the Antaeus::Resources module / namespace
include Antaeus::Resources

# Retrieve all guests with "gmail.com" in their email address
guests = Guest.all(client: client).where(:email, /gmail\.com/, comparison: :match)
# Or
all_guests = Guest.all(client: client)
guests = all_guests.where(:email, /gmail\.com/, comparison: :match)
# Or even
guests = Guest.where(:email, /gmail\.com/, comparison: :match, client: client)

The #where() is an instance method on the Antaeus::ResourceCollection class, which means that the searching is actually done locally. For small installations of Antaeus (or especially powerful client machines), this is likely the fastest way to do searching. That said, Antaeus::Resource also provides a .search() method that submits queries to the server for processing, returning only matching resources. This style of searching is less flexible, and may be slower for some operations given the lazy-loading of resource model data employed by this SDK.

The following resource classes (all under the Antaeus::Resources namespace) are available for typical API operations:

  • Appointment
    • Used for creating, listing, and managing guest appointments
  • Group
    • Read-only, used for listing and querying backend groups and their members. Only available to administrators and via the UserAPIClient
  • Guest
    • Used for creating, listing, and managing guests.
  • Hook
    • Used to configure plugins, targeting certain plugins at named system events. Only available to administrators and via the UserAPIClient
  • Location
    • Used for creating, listing, and managing office locations. Read-only to non-administrators.
  • RemoteApplication
    • Used for creating, listing, and managing remote front-end applications to the API. This is for very advanced cases only (such as integrating with different authentication systems). Only available to administrators and via the UserAPIClient
  • User
    • Read-only, used for listing and querying backend users.

These do not correlate 1:1 with objects defined in the API, but they are a close and convenient approximation.
