Ruby Trello API

This library implements the Trello API.

Trello is an awesome tool for organization. Not just aimed at developers, but everybody. Seriously, check it out.

Full API documentation.

Installation

# gem install ruby-trello

Full Disclosure: This library is mostly complete, if you do find anything missing or not functioning as you expect it to, please let us know.

Supports Ruby 2.0 or newer. Version 1.3.0 is the last version that supports Ruby that is older than 1.9.3.

Configuration

####Basic authorization:

1. Get your API public key from Trello via the irb console:

$ gem install trello
$ irb -rubygems
irb> require 'trello'
irb> Trello.open_public_key_url                         # copy your public key
irb> Trello.open_authorization_url key: 'yourpublickey' # copy your member token

2. You can now use the public key and member token in your app code:

require 'trello'

Trello.configure do |config|
  config.developer_public_key = TRELLO_DEVELOPER_PUBLIC_KEY # The "key" from step 1
  config.member_token = TRELLO_MEMBER_TOKEN # The token from step 3.
end

####2-legged OAuth authorization

Trello.configure do |config|
  config.consumer_key = TRELLO_CONSUMER_KEY
  config.consumer_secret = TRELLO_CONSUMER_SECRET
  config.oauth_token = TRELLO_OAUTH_TOKEN
  config.oauth_token_secret = TRELLO_OAUTH_TOKEN_SECRET
end

####3-legged OAuth authorization

Trello.configure do |config|
  config.consumer_key    = TRELLO_CONSUMER_KEY
  config.consumer_secret = TRELLO_CONSUMER_SECRET
  config.return_url      = "http://your.site.com/path/to/receive/post"
  config.callback        = lambda { |request_token| DB.save(request_token.key, request_token.secret) }
end

All the calls this library make to Trello require authentication using these keys. Be sure to protect them.

So lets say you want to get information about the user bobtester. We can do something like this:

bob = Trello::Member.find("bobtester")
# Print out his name
puts bob.full_name # "Bob Tester"
# Print his bio
puts bob.bio # A wonderfully delightful test user
# How about a list of his boards?
bob.boards

Multiple Users

Applications that make requests on behalf of multiple Trello users have an alternative to global configuration. For each user's access token/secret pair, instantiate a Trello::Client:

@client_bob = Trello::Client.new(
  :consumer_key => YOUR_CONSUMER_KEY,
  :consumer_secret => YOUR_CONSUMER_SECRET,
  :oauth_token => "Bob's access token",
  :oauth_token_secret => "Bob's access secret"
)

@client_alice = Trello::Client.new(
  :consumer_key => YOUR_CONSUMER_KEY,
  :consumer_secret => YOUR_CONSUMER_SECRET,
  :oauth_token => "Alice's access token",
  :oauth_token_secret => "Alice's access secret"
)

You can now make threadsafe requests as the authenticated user:

Thread.new do
  @client_bob.find(:members, "bobtester")
  @client_bob.find(:boards, "bobs_board_id")
end
Thread.new do
  @client_alice.find(:members, "alicetester")
  @client_alice.find(:boards, "alices_board_id")
end
