Brickset

This gem provides a Ruby wrapper around the Brickset (v2) API, using HTTParty. Brickset is a library to access the Brickset API in an easy way. It wraps all of the methods, which are described in the official documentation. The Brickset API by default responds with XML. This gem maps the XML responses to Ruby objects using HappyMapper.

Installation

Add this line to your application's Gemfile:

gem 'brickset_api', require: 'brickset'

And then execute:

$ bundle

Or install it yourself as:

$ gem install brickset_api

Apply for an API key

You can retrieve an API key from the official Brickset site. Just follow the instructions and once you've received the API key move on to the next step.

Configuration

In order for you to use the Brickset gem, you'll need to configure the API key you've requested in the previous step. If you're using Rails, you could add the following to e.g. config/initializers/brickset.rb:

Brickset.configure do |config|
  config.api_key = '<API_KEY>'
end

That's it. You're now ready to start using this gem.

Usage

Using Brickset is easy. All you need to know is that all calls go through the Brickset::Client class. Most of the API calls provided by the Brickset v2 API require you to sign into Brickset in order for you to retrieve a token (which they call a userHash). This token can than be used to call the authenticated API calls and retrieve information of the signed in user.

Now, you're not required to do so, but if you don't, you will only be able to retrieve generic information from the API. User specific information will not be accessible.

Create an instance of the Brickset client

In order to retrieve data from the API, we'll need an instance of the Brickset client. So let's create it:

client = Brickset.client

Yeah, that's it.

Create an instance of the Brickset client with access to authenticated API calls

If you want to retrieve user specific information you'll need a token. You can retrieve one as follows:

token = Brickset.login('<YOUR_USERNAME>', '<YOUR_PASSWORD>')

Now that you have access to the token, provide the client with it and you'll be good to go:

client = Brickset.client(token: token)

That's it.

Helper methods

There are two helper methods that you can use to check whether your API key and token are valid. Both of them will return a Boolean value. You can use them as follows:

client.valid_api_key? # => true
client.valid_token?   # => true

Calling API methods

Now, let's call our sets method with Star Wars (because its awesome, obviously) as a theme:

sets = client.sets(theme: 'Star Wars')

The above call will return all sets that are in the Star Wars theme. As can be seen on the API page (look for getSets), there's a default limit of 20 records per page to retrieve. You could change that with the following:

sets = client.sets(theme: 'Star Wars', page_size: 50)

Or navigate to the second page:

sets = client.sets(theme: 'Star Wars', page_number: 2)

Let's say you're looking for the Ultimate Collector Series sets and more specifically the ones based on the Millenium Falcon. You can retrieve those with the following example:

sets = client.sets(theme: 'Star Wars', subtheme: 'Ultimate Collector Series', query: 'Millenium Falcon')

At the time of writing this will result in two sets: 10179-1 from 2007 and 75192-1 from 2017. Let's say we want to select the last one to view its data:

sets = client.sets(theme: 'Star Wars', subtheme: 'Ultimate Collector Series', query: 'Millenium Falcon')
set  = sets.last           # => #<Brickset::Elements::Set:0x000055ad9ddfdd60 @set_id=26725, @number="75192", @number_variant=1, @name="Millennium Falcon", @year="2017", @description=nil, @category="Normal", @theme="Star Wars", @theme_group="Licensed", @subtheme="Ultimate Collector Series", @pieces="7541", @minifigs="8", @image=true, @image_url="https://images.brickset.com/sets/images/75192-1.jpg", @image_filename="75192-1", @thumbnail_url="https://images.brickset.com/sets/thumbs/tn_75192-1_jpg.jpg", @thumbnail_url_large="https://images.brickset.com/sets/small/75192-1.jpg", @brickset_url="https://brickset.com/sets/75192-1", @owned_by_total=5194, @wanted_by_total=4551, @released=true, @rating=5.0, @user_rating=4, @review_count=3, @instructions_count=2, @additional_image_count=61, @last_updated=Thu, 14 Sep 2017, @age_minimum=16, @age_maximum=nil, @notes=nil, @tags=nil, @retail_price_uk="649.99", @retail_price_us="799.99", @retail_price_ca="899.99", @retail_price_eu="799.99", @date_added_to_shop="2018-01-10", @date_removed_from_shop="", @packaging_type="Box", @height=0.0, @width=0.0, @depth=0.0, @weight=0.0, @availability="LEGO exclusive", @ean="", @upc="", @acm_data_count=0, @owned=true, @wanted=true, @number_owned=1, @user_notes="">

set.id                     # => 26725
set.pieces                 # => '7541'
set.image_url              # => 'https://images.brickset.com/sets/images/75192-1.jpg'
set.additional_image_count # => 61

You could now use additional_images to retrieve the 61 additional images from the above set. Simply supply the API call with the set ID:

client.additional_images(set.id)

# => [#<Brickset::Elements::AdditionalImage:0x000055ad9e0292b0 @thumbnail_url="https://images.brickset.com/sets/AdditionalImages/75192-1/tn_75192_1to1_jpg.jpg", @thumbnail_url_large=nil, @image_url="https://images.brickset.com/sets/AdditionalImages/75192-1/75192_1to1.jpg">, #<Brickset::Elements::AdditionalImage:0x000055ad9e027d98 @thumbnail_url="https://images.brickset.com/sets/AdditionalImages/75192-1/tn_75192_alt10_jpg.jpg", @thumbnail_url_large=nil, @image_url="https://images.brickset.com/sets/AdditionalImages/75192-1/75192_alt10.jpg">, ...]

It really is that easy. Need a specific method? Look for them in the lib/brickset/api directory.
