Create a simple JRuby app with access to live Calendly data.
JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for Calendly makes it easy to integrate connectivity to live Calendly data in JRuby. This article shows how to create a simple JRuby app that connects to Calendly data, executes a query, and displays the results.
Configure a JDBC Connection to Calendly Data
Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for Calendly\lib).
JRuby natively supports JDBC, so you can easily connect to Calendly and execute SQL queries. Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.
Start by setting the Profile connection property to the location of the Calendly Profile on disk (e.g. C:\profiles\CalendlyProfile.apip). Next, set the ProfileSettings connection property to the connection string for Calendly (see below).
Calendly API Profile Settings
To authenticate to Calendly, you will need to provide an API Key. The Calendly API Key, can be found in your Calendly account, under 'Integrations' > 'API & Webhooks' > 'Generate New Token'. Set the APIKey in the ProfileSettings connection property.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the Calendly JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.api.jar
Fill in the connection properties and copy the connection string to the clipboard.
Below is a typical JDBC connection string for Calendly:
jdbc:api:Profile=C:\profiles\Calendly.apip;ProfileSettings='APIKey=your_api_token';
Create a JRuby App with Connectivity to Calendly Data
Create a new Ruby file (for example: APISelect.rb) and open it in a text editor. Copy the following code into your file:
require 'java'
require 'rubygems'
require 'C:/Program Files/CData/CData JDBC Driver for Calendly 2018/lib/cdata.jdbc.api.jar'
url = "jdbc:api:Profile=C:\profiles\Calendly.apip;ProfileSettings='APIKey=your_api_token';"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Uri, Name FROM OrganizationScheduledEvents")
while (rs.next) do
puts rs.getString(1) + ' ' + rs.getString(2)
end
With the file completed, you are ready to display your Calendly data with JRuby. To do so, simply run your file from the command line:
jruby -S APISelect.rb
