Parliament Data API Wrapper (Ruby)
NOTE: This gem is in active development and is likely to change at short notice. It is not recommended that you use this in any production environment.
- Getting Started with Development
parliament-ruby requires the following:
This gem is currently not available on RubyGems. To use it in an application, install it directly from GitHub via your Gemfile
gem 'parliament', git: 'https://github.com/ukparliament/parliament-ruby.git', branch: 'master'
This gem's main function is fetching an n-triple file from a remote server and converting it into linked ruby objects.
Setting up a connection
In order to connect to a remote server, we first need to set a base_url value, from which we will build an 'endpoint'. The base_url should be the beginning of a url without the trailing slash. For example
http://example.com instead of
parliament = ::.(base_url: 'http://test.com')
Setting a base URL 'globally'
Within code you can set a global base URL using the following snippet.
::. = 'http://test.com' # The base_url should be set for all new objects ::.. #=> 'http://test.com' # You can still override the base_url on an instance by instance basis ::.(base_url: 'http://example.com'). #=> 'http://example.com'
Alternatively, you can set the environment variable
PARLIAMENT_BASE_URL on your machine and we will automatically use that.
ENV['PARLIAMENT_BASE_URL'] #=> 'http://example.com' ::. #=> nil ::.. #=> 'http://example.com'
Building an 'endpoint'
Now that we have a
base_url set, we will want to build an 'endpoint' such as:
An endpoint is effectively just a full URL to an n-triple file on a remote server.
Building an endpoint is simple, once you have a Parliament::Request object, you do something like this:
parliament = ::.(base_url: 'http://test.com') #=> #<Parliament::Request> # target endpoint: 'http://test.com/parties/current' parliament.parties.current.get # target endpoint: 'http://test.com/parties/123/people/current' parliament.parties('123').people.current.get # target endpoint: 'http://test.com/people/123/letters/456' parliament.people('123').letters('456').get
Once you've built your endpoint (
parliament.people.current), we use the
#get method to tell us you're finished building and ready to get the data.
