rake aborted! uninitialized constant <ClassName> - ruby-on-rails

Question

Hi um quite new to rails and currently working on a task definition in rake file . This is my code
test_task.rake
namespace :test_name_space do
namespace :to do
task :my_task do
p "========================="
sample_out_put = SOutput.new
sample_out_put.createfileoutput
end
end
end
and in my SOutput
class SOutput
def createfileoutput
current_time = Time.new
puts "====================================="
puts "This is a scheduled file output"
puts "====================================="
File.open("/home/kalanamith/Desktop/out.txt", "a+") do |file|
p current_time.inspect.to_s
file.write("This is a sample test")
file.write(current_time.inspect.to_s)
end
end
fileoutput = SOutput.new
fileoutput.createfileoutput
end
and when I run the
rake test_name_space:to:my_task
"========================="
rake aborted!
uninitialized constant SOutput
um getting above error
I dont have a big picture about this error. Can anyone guide me?
