Hello everyone,
Im using a charting plugin called openflashcharts and I seem to be
getting an error when trying to use respond to. Now I know hashes are
supposed to have an even amount of elements in them, but I dont see
where I am going wrong. Heres my code:
def index
workouts = Workout.find_all_by_user_id(current_user.id)
spinclasses = SpinClass.find_all_by_user_id(current_user.id)
workouts_array = Array.new
spinclasses_array = Array.new
workouts.each do |w|
workouts_array << [w.created_at.to_date, w.calories_burned]
end
spinclasses.each do |sc|
spinclasses_array << [sc.created_at.to_date,
sc.calories_burned]
end
title = Title.new("Calories burned.")
respond_to do |wants|
wants.html
{
@graph = open_flash_chart_object(600, 300, url_for(:action =>
'index', :format => :json))
}
wants.json
{
line = Line.new()
line.text = "Line"
line.width = 1
line.colour = '#5E4725'
line.dot_size = 5
line.values = workouts_array
chart = OpenFlashChart.new(title)
chart.add_element(line)
render :text => chart, :layout => false
}
end
end
and heres my error:
/Users/Zack/Desktop/General/Rails/ergotech/app/controllers/charts_controller.rb:25:
odd number list for Hash
/Users/Zack/Desktop/General/Rails/ergotech/app/controllers/charts_controller.rb:30:
