Connect to Deepgram Data in Ruby

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

Create an ODBC Connection to Deepgram 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.

Start by setting the Profile connection property to the location of the Deepgram Profile on disk (e.g. C:\profiles\Deepgram.apip). Next, set the ProfileSettings connection property to the connection string for Deepgram (see below).

Deepgram API Profile Settings

Deepgram uses API key authentication for all endpoints. API keys are scoped to a project and carry permission scopes (member, administrator, or owner). Create and manage API keys in the Deepgram console.

After obtaining your API key, set the following connection properties:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your Deepgram API key.

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 Deepgram Data

Create a new Ruby file (for example: APISelect.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 API Source','','')

#execute a SELECT query and store the result set
resultSet = cnxn.execute("SELECT ApiKeyId, MemberEmail FROM Keys WHERE ProjectId = 'your-project-id'")

#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 Deepgram data with Ruby. To do so, simply run your file from the command line:

ruby APISelect.rb
