Ruby on rails Class being mistaken as a Constant - ruby-on-rails

Question

First of all, I'm experimenting with Ruby on Rails for the first time.
I'm doing a simple exercise of designing a form to receive events information and save those events in Google Calendar.
To save the events on Google Calendar I'm using the following gem: http://googlecalendar.rubyforge.org/
I have the following code for the view.
<h1>Welcome to Ruby On Rails Calendar</h1>
<h3>Add Event</h3>
<form action="/google_calendar/create" method="post">
<table>
<tr>
<td>Title</td><td><input type="text" /></td>
</tr>
<tr>
<td>Begin Date</td><td><input type="date" name="begindate" id="bagindate" /><input type="time" name="beginhour" id="beginhour" /></td>
</tr>
<tr>
<td>End Date</td><td><input type="date" name="enddate" id="enddate" /><input type="time" name="endhour" id="endhour" /></td>
</tr>
<tr>
<td>Local</td><td><input type="text" name="local" id="local" /></td>
</tr>
<tr>
<td>Description</td><td><input type="textarea" rows="10" name="description" id="description" /></td>
</tr>
<tr>
<td><input type="Submit" value="Save" /></td>
</tr>
</table>
</form>
<%= #result_message %>
And for the controller I have this code (mostly taken from the gem site I shared previously).
class GoogleCalendarController < ApplicationController
def create
send_event(params[:title],params[:begindate] + " " + params[:beginhour], params[:enddate] + " " + params[:endhour], params[:local], params[:description])
#result_message = 'Event sent successfully'
render :welcome => index
end
private def send_event(title, begin_datetime, end_datetime, local, description)
require 'googlecalendar'
google_calendar_service = GData.new
google_calendar_service.login(Rails.configuration.google_calendar_email, Rails.configuration.google_calendar_password)
event = { :title => title,
:content => description,
:where => local,
:startTime => begin_datetime,
:endTime => end_datetime}
google_calendar_service.new_event(event)
end
end
The thing is that when I try to save an event I get the following error.
uninitialized constant GoogleCalendarController::GData
Supposedly GData is a class defined in the googlecalendar gem, but seems to not being recognized as such.
I have gem 'googlecalendar' on my Gemfile, did bundle install and it appears when I do bundle show googlecalendar.
Does anyone know what can be causing this?

Answer 1

The documentation is little bit wrong
try this
require 'googlecalendar'
google_calendar_service = Googlecalendar::GData.new
Since you didnot specify the namespace so first Ruby searched it in the ::global namespace and didnot find, so expected it to be GoogleCalendarController::GData
References
Code from the gem's lib/googlecalendar.rb, you can see the namespace is Googlecalendar
$:.unshift(File.dirname(__FILE__)) unless
$:.include?(File.dirname(__FILE__)) || $:.include?(File.expand_path(File.dirname(__FILE__)))
module Googlecalendar
# List of lib files to include
FILES = %w{calendar.rb dsl.rb event.rb gcalendar.rb gdata.rb ical.rb net.rb version.rb}
end
# Add all FILES as require
Googlecalendar::FILES.each { |f| require "googlecalendar/#{f}"}
