Connect to Trello Data in Ruby


Connect to Trello data in Ruby with ruby-dbi, dbd-odbc, and ruby-odbc.

The CData ODBC Driver for Trello makes it easy to integrate connectivity to live Trello data in Ruby. This article shows how to create a simple Ruby app that connects to Trello data, executes a query, and displays the results.

Create an ODBC Connection to Trello Data

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Trello uses token-based authentication to grant third-party applications access to their API. When a user has granted an application access to their data, the application is given a token that can be used to make requests to Trello's API.

Trello's API can be accessed in 2 different ways. The first is using Trello's own Authorization Route, and the second is using OAuth1.0.

  • Authorization Route: At the moment of registration, Trello assigns an API key and Token to the account. See the Help documentation for information on how to connect via the Authorization route.
  • OAuth Route: Similar to using Authorization, OAuth creates an Application Id and Secret when you create your account. See the Help documentation for information on how to to connect.

Installing Ruby and Necessary Gems

If you do not have Ruby installed, refer to the Ruby installation page. With Ruby installed, you will need to install the ruby-dbi, dbd-odbc, and ruby-odbc gems:

gem install dbi gem install dbd-odbc gem install ruby-odbc

Create a Ruby App with Connectivity to Trello Data

Create a new Ruby file (for example: TrelloSelect.rb) and open it in a text editor. Copy the following code into your file:

#connect to the DSN require 'DBI' cnxn = DBI.connect('DBI:ODBC:CData Trello Source','','') #execute a SELECT query and store the result set resultSet = cnxn.execute("SELECT BoardId, Name FROM Boards WHERE Name = 'Public Board'") #display the names of the columns resultSet.column_names.each do |name| print name, "\t" end puts #display the results while row = resultSet.fetch do (0..resultSet.column_names.size - 1).each do |n| print row[n], "\t" end puts end resultSet.finish #close the connection cnxn.disconnect if cnxn

With the file completed, you are ready to display your Trello data with Ruby. To do so, simply run your file from the command line:

ruby TrelloSelect.rb Writing SQL-92 queries to Trello allows you to quickly and easily incorporate Trello data into your own Ruby applications. Download a free trial today!
