Trying to connect rails app to trello APi

Question

I am trying to connect my rails app to the trello API. I have asked for tokens and secrets at https://trello.com/app-key I have installed the ruby gem 'ruby-trello' in my gemfile.

I need to generate a trello card with on submit of my contact form with the email submitted, the message's object and the message content. This is my create method in contact_controller.rb

def create
    @contact = Contact.new(contact_params)
    if @contact.save
      redirect_to root_path
      flash[:alert] = "Votre message a bien été envoyé à l'équipe TennisMatch, nous vous contacterons dans les plus brefs délais !"

        Trello.configure do |config|
          config.developer_public_key = ENV['PUBLIC_TRELLO_KEY']
          config.member_token = ENV['MEMBER_TRELLO_TOKEN']
        end
        me = Trello::Member.find("david_geismar")

      # find first board
      board = me.boards.first
      puts board.name
      # puts "Lists: #{board.lists.map {|x| x.name}.join(', ')}"
      # puts "Members: #{board.members.map {|x| x.full_name}.join(', ')}"
      board.cards.each do |card|
            puts "fu"
            # puts "-- Actions: #{card.actions.nil? ? 0 : card.actions.count}"
            # puts "-- Members: #{card.members.count}"
            # puts "-- Labels: #{card.labels.count}"
      end
    else
      render 'new'
    end
  end

my application.yml file looks like this:

development:
      PUBLIC_TRELLO_KEY: "******"
      MEMBER_TRELLO_TOKEN: "******"

But everytime I am submitting my contact form I get the error : invalid token

here's the actual log:

Redirected to http://localhost:3000/ E, [2015-06-17T01:47:19.732876 #11385] ERROR -- : [401 GET https://api.trello.com/1/members/david_geismar]: invalid token

Answer 1

Environment variables placed in application.yml are not automatically populated in your Rails environment. You might want to take a look at the dotenv gem, which makes this super easy IMO. Essentially, you can place your environment variables in a top level file called .env and the gem handles getting them installed in your environment.

Otherwise, you can add a bit of code in an initializer to read these into your environment.

Answer 2

Are you sure you load your application.yml ?

It is not loaded by default, you must add:

ENV.update YAML.load_file('config/application.yml')[Rails.env] rescue {}

to config/application.rb

Answer 3

You might not be using the correct member token.

The 'secret' displayed on your https://trello.com/app-key page is not a member token.

You can obtain a member token by authorizing your app in a browser and copying the returned string. Use the following URL:

https://trello.com/1/authorize?key=YOUR_API_KEY&scope=read%2Cwrite&name=APP_NAME&expiration=never&response_type=token

• key = your developer API key
• scope = read,write to give you full access
• name = app name that appears in the authorization dialog, seems arbitrary
• expiration = never so that you don't need to keep renewing, default is 30 days
• response_type = token string that can be copied to your Rails config

The 'secret' is not used here at all. It seems to be only used for the oAuth method of authenticating.
