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: odd number list for Hash /Users/Zack/Desktop/General/Rails/ergotech/app/controllers/charts_controller.rb:31: syntax error, unexpected tIDENTIFIER, expecting '}' line.text = "Line" ^ /Users/Zack/Desktop/General/Rails/ergotech/app/controllers/charts_controller.rb:40: syntax error, unexpected '}', expecting kEND /Users/Zack/Desktop/General/Rails/ergotech/app/controllers/charts_controller.rb:54: syntax error, unexpected $end, expecting kEND
Many thanks,
zack.
